Lonicera japónica var. Halliana (twining).
Lonicera japónica var. Halliana (twining).
Lycium chínense and L . halimifolium. Both are shrubs with recurving trailing stems which do not twine. Plant must be fastened to its support. Excellent to hold banks, but very vigorous and may become a nuisance.
Lycium chínense and L . halimifolium. Both are shrubs with recurving trailing stems which do not twine. Plant must be fastened to its support. Excellent to hold banks, but very vigorous and may become a nuisance.
Tall-growing vines reaching eaves of the house.
Actinidia arguta (vigorous; dark glossy foliage, twining).
Aristolochia macrophylla. Twining; large Heavy foliage; should not be used unless dense shadeis desired.
Campsis radicans. This is a heavy vine climbing by root-like holdfasts which are too weak to hold it in storm or wind; must be fastened to its support. Somewhat tender in the N. and usually has more or less dead wood. Better when used as porch or pillar vine where it can be reached and pruned easily.
Celaatrus scandens (twining).Parthenocissus. All kinds; tendrils with or without disks.
Wisteria chinensis. The finest of tall-growing vines; vigorous and hardy at all times.Vines for foliage only. All in the following list are deciduous, i. e., drop their leaves in winter. The only evergreen vines which can be used in the North are Evonymus radicans and Hedera helix. Even the foliage of Evonymus radicans will occasionally burn in winter although it is hardier than English ivy in this respect. Vinca minor and Pachysandra terminalis are good creeping plants for evergreen ground-cover and Hall's honeysuckle is semi-evergreen, holding good foliage until Christmas. Other flowering vines also good in foliage arc Clematis paniculata, Forsythia suspensa, which is a shrub with recurving and trailing stems excellentfor running over a bank or hanging down a wall, Rosa Wichuraiana and some of its many hybrids,and Wisteria chinensis.
Actinidia arguta.
Akebia quinata. Very graceful vine with delicate five-parted foliage.
semi-evergreen, remaining until January; twining. Aristolochia macrophylla.
Celastrus scandens (berries red and orange all winter; twining).
Lycium halimifolium.
Parthenocissus quinquefolia. Beautiful red autumn color; first vine
to color in the fall; climbs by tendrils usually without disks
except in var. Engelmannii. Parthenocissus tricuspidata var. Veitchii (beautiful autumn color;
climbs by tendrils ending in disks). Smilax rotundifolia. A vigorous wild vine with thick
glossy foliage
enduring both shade and wet soil. Vitis Coignetiae. From Japan; a vigorous grower with immense
leathery leaves usually brown felty beneath; the foliage is
especially strong and bold and turns a rich red color in fall.
Vines for flower. Plants marked with an asterisk(*) have attractive foliage as well as bloom
Campsis radicans. A heavy vine.
Clematis Jackmanii. Climbs by twisting leaf-stems. Flowers large and purple. C. Jackmanii var.alba is similar, but the flowers are creamy white. Both of these are good vines for bloom in July and August.
Clematis paniculata. Climbs as does the preceding species. Flowers small and white, covering
plant with a mass of bloom in September and October. Foliage remains glossy green, good until
December. The best fall-blooming vine.
Forsythia suspensa. Flowers yellow, appearing before the leaves covering the plant with a mass of bloom in April. Flower- buds of ten killed by cold in the northern tier of states.
Lonicera Heckrottii. Climbs by twining. This is a hybrid which blooms continuously during July,August, and September. The flowers are rose outside and yellow inside, and as open and closed flowers are present at the same time they make a very handsome showing. The only objection to the plant is that it is badly infested with aphids or green-flies.
Lonicera japonica var. Halliana. Bloom profuse and fragrant; flowers white, fading yellow in June and July.
Rambler roses, in order of bloom, June and July. These must be tied up. but are hardy without protection except possibly in the northern tier of states. In such cold places one must be content with the upright shrubby Rosa rugosa in white, and red varieties, both single and double, beginning in early June; with the white Rosa multiflora, beginning from middle to late June; and with the pink Prairie, or Michigan, rose (Rosa setigera) which does not begin until the second week in July. R. multiflora and R. setigera are both shrubs with arching habit and have produced many Rambler roses.Of the varieties following ,those marked with the a dagger(+) are the best: + Tausendscbon middle June,double,delicate pink,larger than Dorothy Perkins; Lady Duncan, single, rich salmon-pink; +Excelsa, late June, or early July, a long-season rose,double, rich crimson, a new variety, blooming at the same season as the old Crimson Rambler, but a better color; Dorothy Perkins, early July, double pink; white Dorothy Perkins, a white variety of the preceding; Alberic Barbier, middle July, semi-double or double creamy white, yellow in center, dark yellow in bud, excellent glossy foliage; Aviator Bleriot is a new variety, very similar to Alberic Barbier; +Hiawatha. middle July, a long-season rose, single, bright red with white center and yellow stamens; +Mrs. H. M.Walsh, middle July, double, white,same long season and good foliage as Rosa Wichuraiana, the Memorial rose of which it is practically a
double form; +R.Wichuraiana, which is blooming at this time, is the parent of many of the varieties named above, and is itself a very attractive rose.
Wisteria chinensis. A strong, twining vine, with long, hanging clusters of white or purple
flowers, according to variety, in middle and late May. Leaves alternate, compound, large, loose, and feathery. Beautiful in flower, graceful in habit, satisfactory in foliage, and vigorous and hardy at all times.
Large trees for wind protection and for background setting to the house.
Deciduous: These deciduous types are dense and compact in habit and make a good screen or background even after the leaves are gone in winter.
Acer platanoides.
Acer saccharum.
Esculus Hippocastanum.
Fagus sylvatica.
Quercus alba.
Tilia europaea.
Evergreen: The Scotch pine (Pinus sylvestris), Norway spruce (Picea excelsa), and Colorado blue spruce (Picea pungens) are probably the three most commonly planted evergreen trees. The Scotch pine is the best of the three for neutral mass planting but none is so satisfactory as the hemlock or the pines listed below. The Scotch pine has an irregular spreading habit with bluish green foliage, salmon-colored limbs and trunk and picturesque habit when old. It grows rapidly but is shortlived in America. The Norway spruce and Colorado blue spruce are both conical
evergreens and for this reason alone they are always emphatic and conspicuous. Even when planted in mass the individuals are so distinct that it requires years for them to merge into a uniform solid mass. Comparing a solid planting of Norway spruce with a similar planting of
hemlock, it is seen that in fhe former every individual spruce is stiff and conical and remains so for years, while the hemlocks with their graceful form and habit have lost their individuality and merged into one indefinite mass. The Norway spruce is also too somber and
funereal for cheerful home-ground planting. It is also short-lived in America and while hardy and rapid-growing it begins to go back and die at the top after forty or fifty years except in very favorable locations. The Colorado blue spruce is also short-lived in the eastern states and is altogether too conspicuous and emphatic both in form and color for neutral background planting.
Pinus austriaca.
Pinus resinosa.
Pinus Strobus,
Pseudotsuga taxifolia. This is a large conical tree like Norway spruce and therefore not so good for neutral background planting as either the pines or the hemlock mentioned in this same list. But it is the best of the conical spruce or fir type because more graceful in habit, with
soft more flexible foliage which is green or gray-green in color. It is a vigorous grower and though little known it is a very promising evergreen tree. Only the Rocky Mountain form is hardy in tne East.
Tsuga canadensis, the common hemlock.
Rapid-growing trees for screens. As a class, the rapid- growing trees are weak-wooded and transient. They are cheap and are usually thought of as fillers for temporary or quick effects until more permanent trees can be established.
Deciduous:
Acer Negundo.
Acer saccharinum.
Populus, Carolina poplar.
Evergreen:
Picea excelsa.
Pinus sylvestris. These are probably the fastest growing evergreen trees but they are not so long-lived as white pine, nor do they make either as graceful or as effective screen.
Screens tall and narrow (10 to 15 feet). Space the plants 2-3 feet apart in single row. For taller and more rapid-growing material, use Lombardy poplar (Populus nigra var. italica), or
upright sugar maple (Acer saccharum var. monumentale), 6 feet apart in the row. This latter is a new and very desirable form. It is durable and slower-growing like the sugar maple but narrow and upright like the Lombardy poplar. Bolle's poplar (Populus alba var. pyramidalis) is a
narrow upright form of the European white poplar and is just as undesirable as that tree. Moreover, the white woolly coating on the under side of the leaves makes the tree very conspicuous and when pronounced color is thus added to narrow upright form the tree becomes too emphatic for ordinary use. The Lombardy poplar with its normal green foliage is much safer to use when either vertical emphasis or a tall narrow screen is needed.
Deciduous:
Carpinus Betulus var. globosa. This is a compact upright variety of the European hornbeam. Excellent hedge-plant but very slow- growing. A plant standing in the open at Arnold Arboretum, Boston, has grown 6 feet wide and 12 feet high in 25 years. Perfectly hardy and,like Berberis Thunbergii, so dense that it makes a definite screen even after the leaves have fallen.
Quercus pedunculata var. fastigiata compacta (a compact upright form of the English oak).
Evergreen :Chamaecyparis nootkatensis. This is little known in the East as yet but has all the requirements for an ideal hedge-plant, tall and narrow. Plante observed in the open at Ithaca, New York, are perfectly hardy and have grown 5 feet wide and 7 feet high in twelve years. They
have not been protected nor trimmed nor specially cared for in any way. They are upright and oval in shape and very dense and compact. The foliage is thick and soft to the touch.
Juniperus chinensis. Resembles the native red cedar, J. vir- giniana, but is better because the foliage does not brown in winter. Also the leaves are more spreading and their bluish gray upper surfaces more noticeable which gives the spray a fuller and lighter-colored appearance.
Juniperus communis var. hibernica. This should be trained in the nursery to one central stem. When young the Irish juniper is a handsome narrow upright plant with bright gray-green foliage; but it grows much more rapidly than other cedars and soon looks miserable because, as now grown, its more or less equal upright parts become too heavy to support themselves and spread apart destroying the symmetry of the plant as well as revealing the dead and unsightly inner foliage.
Juniperus virginiana.
Taxus baccata var. hibernica (not quite hardy above N. Y. City).
Thuya occidentalis var. pyramidalis.
Thuya orientalis. This resembles the native arborvitae but is more handsome. Its branches and branchlets are also more distinctly vertical and the foliage smaller and brighter green.

habit but with good foliage will make very effective screen-planting when massed together):
Deciduous :
Berberís Thunbergii (occasionally 6 feet).
Catalpa Bungei. This is the trade name for C. bignonioides var. nana. It is simply a dwarf variety of the southern catalpa and makes a dense round bush when growing on its own roots. It is often grafted high on upright stem and planted as a substitute for bay trees.
Chaenomeles japonica.
Deutxia gracílis (2 to 3 feet).
Deutxia Lemoinei (3 to 4 feet).

Winter protection of planting.
Winter protection is the preparing of plants to withstand the winter (Figs. 3032-3047). All plants are usually hardy in their own habitat, but many become tender when removed to a colder climate, requiring artificial protection. A permanent covering of snow furnishes ideal
protection, but unfortunately the American winters are very changeable. Continued steady cold is seldom injurious, but the alternate freezing and thawing toward spring are often fatal, the damage varying according as the situation is wet or dry and the soil light or heavy. For example, shallow- rooted plants, as Lobelia cardinalis, will often be thrown out of the ground in clayey soil. Such damage may be prevented by placing sods over the plants. Gail- lardias will winter safely in light well-drained soils with ordinary protection, but perish if wet and
heavy. The remarks in this article are meant to apply in the vicinity of Chicago.
Winter-covering intercepts the sun's rays and retards premature activity. It is as essential "to keep in the cold" during temporary warm spells as it is to retard excessive depth of frost. More damage is generally done in February and March than earlier. Roses and other shrubs may be prepared for the winter any time from the last half of November until well into December, but any plants of an herbaceous nature may be covered much earlier. Where field-mice are troublesome it is well to defer covering until after a good freeze, so that these nibblers may seek other winter quarters. Rabbits are fond of the Japan quince, Spiraea Van- houttei, Evonymus alata, and some others, and often damage newly planted material the first winter. When the branches are beyond their reach, protect the trunk with straw, tar paper, or burlaps, which will also prevent sun-blistering. If the shrubs are in groups or low- branched, run wire netting around them. Fall-planted material should be better protected against frost than established plants of the same species. All the Japanese flowering forms of the plum, peach,
and cherry tribes should have their roots mulched 4 or more inches deep. The fatal damage in the winter of 1898-1899 was at the roots, not overhead. Figs. 3032, 3033 show protection by means of straw and boughs; Figs. 3034-3036, protection inside of boxes, barrels, and wire netting.
Plants with evergreen foliage, like Heuchera sanguinea, are safer with a covering that will not mat down and rot the foliage or injure the crown. The danger is in open, wet seasons. Forest leaves are excellent for winter covering, provided they do not mat down. Oak leaves are good,
but those of elm, maple, and other trees that shed their foliage early are soft and mat too much. Leaves may be held in place by evergreen boughs, brush, or tops of bushy perennials like the native asters, or coarse strawy material. When leaves are used in barrels or boxes, the top of the package should be water-tight, and the leaves dry when put in. This precaution is not essential in all cases, but it is a safe rule to follow. Tar paper is comparatively cheap and comes handy in many phases of winter-covering. Gather the leaves when they are dry, and store under shelter until wanted. Save vines like those of Clematis paniculata and pole limas; they are good for covering climbing roses that are almost hardy. These keep off the bright sun when the plants are in a semi-frozen condition, shield them from the drying winds, and retard premature starting of the flower-buds. Forsythia suspensa trained as a climber on a south wall is benefited by such covering, or by burlaps, as its sheltered position induces activity too early and its flowering buds become a victim to late frosts. Any rhizomatous iris, such as the German iris, should be planted where surface drainage is ample, and in the case of young plants, or those recently divided, not covered with heavy manure or they are likely to decay in wet weather. Cover such plants with light material. Old established plants seldom need protection. Chrysanthemum coccineum requires similar conditions and treatment. All lilies except the hardiest, such as L. tigrinum, L. elegans, L. canadense, L. superbum, L.philadelphicum, L. spe- ciosum, L. tenuifolium, and so on, are best covered by a mound of ashes—wood or coal—which retains an even temperature. The other lilies may be mulched with manure and L. candidum with leaves. Eremurus in all its species, and Alstraemeria aurantiaca, require a deep box of leaves and the surrounding soil well mulched. An inverted V-shaped trough placed over such low edging plants as Veronica circae- oides and Thymus Serpyllum var. montanus, is beneficial. It is well to take up a few plants of Monarda did- yma, the double perennial sunflower, and Thymus Serpyllum, and winter them in a frame, over which place a wooden shutter to shed rain,placing leaves or manure on those that remain.
Where permanent windbreaks, such as plantations of evergreens, buildings or solid fences, do not exist, temporary ones should be made of boards, evergreen boughs, corn-stalks, and the like, to protect arboreal plants that are not quite hardy, e. g., in this climate Halesia Carolina, and in the eastern states Magnolia grandiflora, hollies, and the like. Place the windbreak at the sides toward the prevailing winds, generally north and west, and at the sunny side of any evergreen that browns. The boughs or stalks may be attached to wire netting or to cords fastened to stakes.
The so-called retinisporas may have placed over them an empty box open at the top. Shrubs that are still more tender should be boxed, the box having a tight top and ventilation at the sides. In all cases mulch well at the roots. Magnolia Soulangeana, M. speciosa, and plants of similar
degrees of hardiness may have their branches tied in and empty casks placed over them, one sitting partially inside the other, and held in place by stakes. Put a cone-shaped covering over the top to shed the snow. Or poles may be set close to the tree, wigwam fashion. Wrap these with burlaps, or wind string around them for the straw to lean against, and in both instances wrap with straw. The so-called hardy climbing roses, such as the Seven Sisters and Prairie Queen, which are hardy without protection, but are benefited by it, Wichuraiana and its hybrids, Paul Carmine Pillar, Russell Cottage, Crimson Rambler, Thalia, and Lord Penzance Sweetbrier hybrids, if against a wall, may have clematis or other vines placed thickly over them; or if in an open exposed situation, they may be wrapped in straw. (Fig. 3033.) Better
still, hill up the soil rather high at the roots, —to prevent breaking and to afford protection and drainage,— and then take the trouble to extend the mound in the form of a gradually diminishing ridge. Bend the canes along the ridge, choosing a time when there is no frost in them; then cover the canes with tar paper, over which place soil, strawy manure, or any warm covering. If the presence of a lawn prevents this method, lay on the grass and cover with a water-tight box filled with leaves. Canes will rot directly under an open knothole.In the
spring allow them to remain prostrate some time after uncovering to inure them gradually to the change and to induce the lower buds to strengthen. Hybrid Perpetuáls, the tender forms of Moss roses, Hermosa, Clothilde Sou- pert, and the Dwarf Polyan-thas, may be wrapped, boxed,or bent over and covered with soil. Those in beds may be bent over, the tops tied to the base of their neighbors, lead tags bearing numbers fastened to each plant, and a record taken of their names, and all summer labels stored to prevent loss when removing the leaves in the spring. Make a solid frame around them, higher at one end. and fill with leaves so as to cover the plants. Lap the roof-boards; they will shed water and allow ventilation. In the spring remove the leaves, replace the top for a few days, but let the sides remain for a week or so to shield from cold winds. Keep the plants prostrate until cut back.The tender Hybrid Teas require special attention. Cultivation and watering should be discontinued in September in order to retard a late growth, but if the fall is a dry one, they should receive a thorough soaking late in October. Early in November hill up the soil around the plants to a Height of 6 to 8 inches. After there is a crust of frozen soil a few inches thick, fill up with dry leaves to a little over the height of the hills or higher. Then board up the bed some 21/2 feet high at one side
and 2 feet at the other, and cover top with boards or tar paper, the object being to keep the leaves dry. Hybrid Perpétuais, or in fact any semi-hardy rose of low growth, may be protected as above. In most winters the Hybrid Teas can be safely carried over by hilling up the soil as described and covering with hardwood leaves 18 to 24 inches deep, held down by evergreen boughs, brush, or corn-stalks.
Field-mice or the smaller moles are troublesome sometimes where any open or loose material like leaves or straw is used for winter protection. Plants in cold- frames are often destroyed. This may be prevented by the following method: Procure some poisoned wheat and place in the interior
of a 4- or 5-inch common drain-tile. Place these tiles in the frames or among the roses, using ten grains of wheat to a tile. When spring comes lift up the tile carefully, so as not to spill the wheat and count the grains; by the use of the tiles one keeps track of the wheat and does
not endanger the birds.
Tree peonies and yuccas should have an empty box placed over them, large enough to prevent the plant from touching the wood. Hibiscus syriacus, diervillas, deutzias—except D. Lemoinei and D. parviflora which are hardy—ltea virginica, Cornus mas, and the like, are wrapped in straw, and when the wrappings exceed 4 feet in height they should be staked to prevent high winds from toppling them over. Rhododendrons when planted out are taken up, the roots given a good soaking in a tub, and replanted in cold pits, or in boxes placed in a coldhouse or pits. In the spring,
another bath is given them and the soil firmly pounded around them before replanting. This is essential for continued vigor. Cut all vines of the clematis to within 1 or 2 feet of the ground and lay them down, first mounding the soil a few inches if surface drainage is not good
and cover with ashes, boxed leaves, or soil, or mulch well and wrap the canes with straw. If close to a porch or steps, do not let the swept snow stay over them, unless well protected, as this snow solidifies and excludes air. If. as some now think, the broken outer skin of the
hybrid forms subjects them to disease, then these varieties should not be bent over, but staked and wrapped. It is best not to cut the foliage of the eulalias or the Japan iris, as it, of itself, is a good protection, but manure at the base is essential. Cut down Arundo Donax, cover heavily with any material, and cover all with tar paper or water-tight shutters. Place half-rotted leaf-mold over fern-beds, narcissi, English and Spanish iris or any early-blooming bulbous plant, or a light strawy covering that is easily removed. Fine old manure a few inches thick is good and can remain. Place a good coating of stable manure around the trees on the lawn, and when they have been established any length of time bear in mind that the feeding-roots extend out as far as the branches do. The soil under them has a double duty to perform—to sustain both the tree and the grass. Place short stakes around groups of
platycodons, Asclepiae tuberosa, or any other plants that are late to appear in the spring. Otherwise they may be overlooked in the spring and injured by digging. Examine all labels and see that none is cutting into the limbs of trees. Replace all rotten or defaced ones in the borders, using heavy labels, as thin ones often break off and are carried away when the surplus manure is removed. Cypress is a good material for labels. A. good label for young trees and shrubs is made of a thin sheet of copper. The name is written with, a stylus and a thin white paint rubbed on so as to fill in the depression. The label is fastened to a copper wire ring 3 or 4 inches in diameter, placed around the trunk and allowed to lie on the ground. Such a label is durable, unobtrusive and requires no attention for fear of cutting the wood, nor can it be lost.

Structures for the winter protection of plants.
Pits, cold pits, storage-pits and plant-cellars (Figs. 3038-3047) are structures, with the greater part sunk beneath the surface of the ground, built for the purpose of protecting plants in winter without continued fire- heat. They are employed almost exclusively for storing
dormant plants. They are not suitable for storing growing plants any length of time, neither are they houses in which to grow plants. They should face the south and be sheltered against north winds by buildings or other windbreaks. Owing to their position they should be put in
well-drained ground only and well protected against surface water. A well-designed frame- yard is the best possible place for small pits.
The coldframe used by market-gardeners for wintering cabbage and lettuce for spring plantings, or by the florists for pansies, primroses, forget-me-nots, and the like, is really a simple pit. Such shallow pits, with proper protection, are useful for many other small plants which
would be injured by severe weather. A deep pit, like a coldframe, is shown in Fig. 3037. A pit built on the plan of the old-fashioned "outside cellar" (Fig. 3038) is useful for storing tubers and roots. See that it is well ventilated. A section of another pit is shown in Fig.
3039. More elaborate pits, for accommodating large plants, are illustrated in Figs. 3040-3047.
Double glazed hotbed sashes are now used and can be employed for the pits shown in Figs. 3043-3046, or wherever winter protection is required, as it takes too much time to cover the ordinary sash with mats and shutters. These sashes cost a little more and they are heavier; it
may be well to employ, therefore, a method for ventilation which obviates the necessity of lifting. They lessen the labor and let in sunlight all day. A thin layer of air is shut in by glass; the depth of this layer is the thickness of the sash bar; it keeps in heat and so keeps out frost. It is possible that some dust and perhaps fungous growth may accumulate or form within the layers. The glazing can be done at home, the lower glass being put in without putty and held in grooves on sides and ends and on the sash-bars by thin strips of wood.
For forms of pits, consult Figs. 3043-3046. Figs. 3043-3045 show inexpensive and convenient pits for small and medium-sized plants. They may be built 4 feet or less below the level of the ground, the height and width as shown in the diagrams; the length should be some multiple of 3,any thing between 9 and 30 feet, so that the glass roof may be made of hotbed sash and also protected by the straw mats and wooden shutters in common use. See Hotbeds. These pits are useful for storage in winter and also for carrying some of the hardier greenhouse plants in autumn until the houses are relieved of the chrysanthemum crop. Figs. 3043, 3044 make light hotbeds in spring, if filled with the leaves which formed their winter protection, and are also available for growing such plants as euphorbia during the summer. They are generally too deep
for dung hotbeds. These pits are planned to run east and west. If Fig. 3045 is thus placed, the roof on the north side may be made of plank instead of glass, but if it runs north and south it should have a glass roof on both sides. Easy access to all is obtained through the roof by
removing a sash. Sometimes a door can be built at one end. Fig. 3043 does not cost much more than Fig. 3044, and furnishes more room. By putting a few doors in the board roof, excellent ventilation and access is provided. Fig. 3045 gives the best head-room, but is rather dark for
evergreens with soft foliage, e.g., Cytisus canariensis, unless the whole roof is glass. A pit like this has always been used in the Arnold Arboretum for wintering seedlings, rooted cuttings and grafts,—young stock grown in flats but too delicate for the open ground. The arrangement of shelves shown in the diagram gives storage to large numbers of these small plants. In Fig. 3046 is shown a small plant-cellar, more expensive but with better capacity for large plants. It
should run north and south, and, excepting the glass roof, is wholly below ground, and consequently extremely well protected against frost. The door is at either end or side. By taking advantage of sloping ground it ia possible to enter on the ground-floor level, which is important when large plants in tubs must be handled. In such cases a concrete floor may be built. The monitor roof provides plenty of light and ventilation; wooden shutters cover the glass in cold weather. This form of pit is not only well adapted to plants, but also is excellent for storing fruits and also brussels sprouts, celery, and cauliflower until
Christmas. The forms of buildings larger than those above described vary much with different circumstances. Sometimes the cellar of a stable, tool-house, or other outbuilding can be utilized. The chief consideration is protection against frost, but provision must be made for thorough ventilation, and against a too high temperature in the autumn and early spring. It is because it is hardly possible to provide for these matters that dwelling-house cellars do not make good pits; they cannot be sufficiently ventilated to keep the temperature low enough except in the middle of winter. Growth is incited and cannot be maintained owing to lack of light.
Owing to their position, pits cannot well be made of wood, plank and cedar posts lasting from 4 to 6 years only. For large pits, stone and brick are most economical for walls and ceilings; for small ones concrete probably makes the cheapest and best wall; hollow tile might be used.
At the Bussey Institution the concrete walls of several small pits have stood 15 to 20 years without showing any sign of deterioration.
An excavation of the required dimensions is made, with due allowance for the walls. Inside the excavation a plank molding-frame is built at the proper distance; viz., the thickness of the walls, from the walls of earth which should have been cut as true as possible. This frame,
which should also be true and plumb, is carried to the required height for the inside face of wall and another frame is made at the proper distance on the surface of the ground, the inner face of which will be the outside face of the completed wall. These frames must be well braced; they carry a heavy load until the cement hardens. It is not necessary to make a complete frame for the whole pit at once; one end and a half of both sides can be built first, and the same frame reversed will serve for the remainder. Use a good quality Portland cement mixed one part of cement to two of sand with four or five parts broken stone or gravel which should not be larger than an egg; for floors the broken stone or gravel may be increased to seven or eight parts. The whole should be completely and quite carefully blended with hoe or shovel until each stone is coated. Throw this mass into the space between the
molding-frame and earth wall and settle compactly with a rammer. It is not advisable to mix more than a barrel at once, nor so much as this unless at least six men are employed.
Continuous batches are made until the work is finished. When the top layers are going in, insert 3/4-inch iron bolts 6 to 8 inches long at intervals of 6 feet. These secure the wooden
sills. In warm dry weather the frames can be removed within twenty- four hours or less, but first examine carefully the condition of the concrete. After removal, smooth off any roughness and grout in with a whitewash brush a coat of portland cement mixed with water, but without
sand, thus obtaining a good color and a more homogeneous surface. For several days the work should be shaded and occasionally sprinkled with the hose. Do not attach the woodwork until the concrete is fully hardened. One and one-half barrels of cement make about 1 cubic yard of
concrete, that costs, in place, between five and six dollars, somewhat less if the cost of labor, sand, and gravel is moderate. Build in June or July, so that the concrete will be thoroughly dry before frost.
The construction of a brick roof is shown in Fig. 3046. Concrete could also be used. A good grade hotbed sash make the best glass roof. All sills, cross-bars, and the like, should be made of cypress and painted. The woodwork must be made strong to endure the continual exposures. It
is false economy to stint in quantity or quality. In cellars for nursery stock, a comparatively small amount of light is required, and the low roof is boarded in and shingled, building-paper being used. Planks may be substituted for boards, or the roof may be double.
Sand or gravel, 1 foot deep, makes the best floor, or half sand and half loam where plants are to be heeled-in. A concrete floor should be used only where the drainage is absolutely perfect.
The sides and ends should be banked with leaves or other material. (See Fig. 3039). In the vicinity of Boston this should be done about November 15. The same covering can also be given to low roofs. The glass is protected by mats and shutters, much as in ordinary hotbeds. It is a
good plan to have on hand an extra supply of dry meadow hay to give additional shelter in zero
weather. Pits like those shown in Figs. 3043 and 3045, like greenhouses, should carry more than
one "crop". In early autumn they hold chrysanthemums, carnations, stevias, and the like; next
Rhododendron (Azalea) indica, Cytisus canariensis, heaths, and the like, some of which remain for the winter, while others are replaced by hardy shrubs, bulbs, and other plants for forcing.
For spring and summer use, see above. In eastern Massachusetts gardeners begin to use them in
September, but the final storage sometimes is not finished until Christmas. The longer the
plants can be kept in the open air the better fitted they are for their winter quarters.
In the care of pits, watering and ventilation are of prime importance. When first housed the
plants should be well watered, and, if this is carefully done, it will often be found that no further water is required for plants in tubs and large pots (10 inches or more). This also is true of heeled-in stock. Everything, however, should be so arranged that inspection is easy,
and water should be given when necessary. Plants on the shelves, particularly in small pots
(4-inch), will go dry oftener than those placed on the gravel floor. It is best to water on bright days, when the sashes can be removed. The great difficulty in keeping plants in good condition is owing to the condensation of moisture within the pits at times when it is impossible to open them on account of severe weather; therefore no more water should be given than is absolutely needed. As long as the weather permits, keep the sashes off or the windows
open night and day, and afterward open up whenever possible. On sunny days ventilate whenever the thermometer registers over 20 F., but do not begin until the sun strikes the frames, and shut off early in the afternoon. On mild days, with the mercury above freezing, remove the sashes entirely. This is the best way to get rid of the moisture-laden air, and is essential for keeping evergreen plants with soft foliage in good condition. To change the air in large cellars is more troublesome; here it is advisable to build an open fireplace in which a brisk fire may be kindled on mild days when all win-dows can , be unclosed, thus obtaining a better
circulation than is otherwise possible. Sometimes these large cellars have a line of hot-water pipes or other means of heating, by which not only is better ventilation secured but also additional protection in severe weather.
An unheated greenhouse (Fig. 3042) can sometimes be used advantageously, not only for protection but, if it is warm enough, for growing plants in spring and autumn, and to a certain extent in winter. It is really a pit 5 or 6 feet deep built below ground and attached on the south side to some building already on the place. It might not be satisfactory for the extreme
North but in southern New England and the middle states it is a great help: in European gardens it is sometimes called an alpine house, or, if it is larger and better built, a winter-garden.
Give a southern exposure and have it so arranged that the floor is on the same or nearly the same level as the cellar floor; if this cellar is heated, so much the better. The cellar will be convenient for various operations, also for storing soil and tools; water should be handy. A
door between it and the cellar is a necessity, but there need be none on the outside. The form of roof can be either lean-to or three-quarters span; in the latter form boarding, double if possible, can cover the roof next the house. Use double glazed glass and provide plenty of
ventilation by glass or board shutters: this last is most important. The dimensions should not be less than 10 feet in width and may be more; the length can be any multiple of three so that hotbed sash can be used for the roof. The interior layout should be a walk, not over 2 feet
wide, so placed that convenient and economical access is given the plants. These may be grown on benches, either solid or of boards, or planted in the earth. The great advantage of such a structure is that the plants can be handled from the inside in all weathers. The hardier
plants, like wallflowers and violets, bloom all winter; in autumn it can be used to prolong the chrysanthemum season, in spring it is a good place for starting seedlings, e. g., lettuce, cauliflower, and cabbage, and, if warm enough, an inside hotbed can be made to start tomatoes,
peppers and eggplant also; in it most of the plants named below can be stored or grown. Many plants of doubtful hardiness or of small size can be wintered and tried out. It is much simpler to handle than pits or frames, largely on account of easy access and the storage capabilities
of the cellar. It makes a good place to store plants for forcing and will even flower well tulips, hyacinths, and narcissi. A three-quarters span 12 by 15 feet with 8 feet of glass roof,in southern Massachusetts, well protected in all ways, has recorded on a self-registering thermometer only 24° F. in the last three years, outside temperature going as low as—10°F.Following is a list of plants that may be wintered in pits and frames with satisfactory
results. The list is made for the neighborhood of Boston.
1. Nursery stock of every description.
2. Stocks, cions, and cuttings for winter work.
3. Young nursery stock,—seedlings, cuttings, or grafts too delicate for planting in autumn.
4. Hardy plants for forcing or winter decoration. The temperature of pit or cellar for the above plants should be 35°F. or even lower occasionally. The larger plants should be heeled-in on the floor in sandy loam or in bunk-like shelves along the sides. Instead of loam, sphagnum can be used and is particularly good for cuttings and grafting stock. The very young stock is stored in flats or pans in which it has been grown. For forcing stock, see Farcing, pages 1265-1267.
Those marked with a star (*) are more tender and should not be exposed to frost. They should also be kept in the driest part of the pit.
1. Alstroemeria, canna, dahlia, gladiolus, Milla biflora, montbretia, oxalis for summer bedding, tuberose, tigridia, Zephyranthes Atamasco, Z. candida. Keep the above in dry house-cellars, where no frost penetrates, temperature 35° to 40° F. Dahlias and cannas can be covered with dry sand if prone to wilt. Tigridias should be hung up in bags to avoid mice.
2. Agave, aloe, Lippia citriodora, Datura suaveolens, some of the hardier cacti, e. g., Selenicereus grandiflorus and Opuntia Ficus-indica, Cordyline indivisa, fuchsia, Yucca gloriosa and probably other genera and species of succulent plants. Keep at temperature 35° to 43° F. in a very dry house-cellar, with as much light as possible; too much moisture is destructive.

In eastern Massachusetts, with the possible exception of those marked thus (*), they will bear a few degrees of frost, if not too long continued, without harm. The average temperatures of the pit should be just above freezing, say 35° F. The value of these plants depends upon not only carrying them through the winter in good condition, but also in giving them a good start in the spring. For this purpose a cool greenhouse must be provided; a cold grapery or a house constructed from the sashes used on the pits is equally good, in which the plants can be properly grown until it is warm enough to put them out-of-doors.
4. Anemone japonica and A. coronaira, Bellis perennis, Dianthus Caryophyllus (clove pinks and European carnations from seeds), Galax aphylla, myosotis, primula in variety, including auricula, Persian ranunculus, Viola odorata (tender sorts), pansies. wall-flowers, ettuce,
cabbage, cauliflower and parsley. These planta are wintered in coldframes, which should vary in depth with the size of the plant; sometimes the plants are grown and flowered in the frame, at others they are bedded put when the season permits.
5. Arisaema; arum, calochortus (different species), freesia in variety, iris (tender species), ixia, sparaxis. The above plants can be potted and carried in a pit or frame until wanted in the greenhouse.

Shrubs for the Middle West.
The most popular shrubs in the Middle West, as in any new country, are usually of foreign origin. However, the native shrubs are beginning to play a great part in restoring and intensifying the characteristic beauty of this region. The dominant feature of middle western shrubbery is not apparent to all. This is largely due to the fact that the Middle West contains no unique species that compel universal admiration like the mountain laurel and rhododendrons, which are the crowning glory of the East. Every shrub of importance native to the Middle West is also native to the East. While the Middle West may rival the East in the luxuriance of its shrubbery, it is poorer in species, both native and foreign. About two-fifths of the middle western shrubs that are in general cultivation bear their flowers in flat clusters. These have
been called "symbols of the prairie" since they repeat many times on a small scale the great line of the horizon, which is the strongest feature of the middle western scenery, whether wild or cultivated, treeless or forested. Repetition of the horizontal is conspicuous enough
wherever hawthorns and prairie crab-apples (Pyrus ioensis) are abundant, owing to their strong horizontal branching. Few shrubs, however, have stratified branches. Their suggestion of the prairie is subtler and less insistent, because it appears only in the bloom. The boldest repeater of the prairie among the shrubs is the American black elder, with clusters 6 to 8 inches across. The viburnums and dogwoods have smaller clusters, ranging from 5 inches in diameter down to 2 inches. When wood and prairie meet, the prairie note is sounded more strongly by shrubs with horizontal branches, especially witch-hazel, and by juneherry and gray dogwood which, though erect when young, become intensely stratified when old. This is an important part of the prairie style of landscape gardening. The following lists are therefore classified according to this idea.Stratified shrubs. (Those marked * have horizontal branches, at least when old. The others have flat clusters of flowers.) Low shrubs, suitable for foundation planting and edging borders: Ceanothus americanus and C. ovatus; Hydrangea arborescens; Viburnum acerifolium and V. pubescens.Medium-high shrubs, ordinarily 5 to 6 feet: Cornus Amomum, C. racemosa* (or C. paniculata), and C. stolonifera; Sambucus pubens, S. canadensis, and its var. acutüoba; Viburnum cassinoides, V. dentatum, V. molle, and V. americanum. The last-named is considered by botanists to be the same as the European V. Opulus, but the American form is considered to be freer from plant-lice and is superior in other ways.Tall shrubs, suitable for the back of a border, corner of a house, or high foundation: Aralia spinosa*; Cornus alternifolia* and C. rugosa* (or C. circinata); Hamamelis virginiana*; Physocarpus opulifolius; Viburnum Lentago and V. prunifolium.Non-stratified shrubs.Low shrubs: Amelanchier alnifolia and var. pumila; Diervilla triflda; Evonymus obovata; Prunus pumila; Rhus canadensis (or R. aromatica); Ribes americanum; Rosa virginiana (or R. blanda), R. Carolina, R. humilis, and R. setigera; Rubus hispidus; Symphoricarpos occidentalis and S. orbiculatus.Medium-high shrubs: Corylus americana; Evonymus americana; Ilex verticillata; Rhus copallina, R. glabra, and R. typhina; Ribes aureum and R. Cynosbati; Spiraea alba; Symphoricarpos albus.
Tall shrubs: Aronia arbutifolia and A. melanocarpa; Benzoin aestivale; Cephalanthus
occidentalis; Staphylea trifolia; Zanthoxylum americanum.
The most significant plants in the above list, probably, are sumac and prairie rose. The sumac (Rhys glabra) was undoubtedly the most virile note on the wild prairie, where the summer foliage took on a wonderful gloss. It is still the most gorgeous color in the corn-belt, where brilliant reds are not commonly developed in autumn. The prairie rose, also known as the Michigan or Illinois rose (Rosa setigera), is now much planted beside front doors. The common wild rose of the open prairie is Rosa humilis, which, however, is familiar in the East, while Rosa setigera is decidedly more western in its range. The middle western point of view may be indicated by brief notes on a few other species.
Ceanothus ovatus is thought to be more refined in cultivation than New Jersey tea and has more, "western color;" should combine well with Lilium canadense or L. superbum. Cornus racemosa has been called "sunset dogwood" because in autumn its countless red pedicels make a glow like the characteristic prairie sunset; this and
sumac are prominent in "sunset gardens." Cornus rugosa is a magnificent species, but must have shade. Although hazel (Corylus) may be considered "coarse" in the East, its rugged character pleases the Middle West and its autumn color is unique. Hamamelis virginiana is very popular
because its yellow foliage lights up the autumn woods and because its stratified branches carry the prairie spirit into the woodland. Sambucus pubera, the red elder, will not thrive on clay or in full sun; it wants shade and prefers sandy soil. Symphori-carpos orbiculatus is commonly called "buckbush," and is a familiar sight in pastures. Viburnum
acerifolium is useful for the shady side of the house. Viburnum pubescens is the most floriferous of the viburnums and formerly common near Chicago. Zanthoxylum ameri- canum is almost as common in woodlots as buckbush; the scent of the foliage generally pleases.

Shrubs for midcontinental region.
The following list of shrubs for the most part consists of kinds known to be perfectly hardy and to succeed in the region of St. Louis if planted with usual care and subsequently given reasonably good treatment. Many choice sorts which are not likely to be hardy much north of central Missouri without some protection are indicated by an asterisk (*). A few may not be generally known to the trade and hence procured with some difficulty at present but their value for this region was demonstrated by being grown several years at the Missouri Botanical Gerden.
Azalea and certain other Ericaceae, together with some allied genera like Kalmia that have formed attractive features in many plantations, are not included because they are generally shortlived and require more than ordinary care in planting and subsequent handling.

Shrubs and climbers for the South.
Owing to the great diversity of soil, elevation, and climatic conditions found in the Mountain, Piedmont, and Coastal zones of the South, it is impossible to make or to give an absolutely accurate list of deciduous and broad-leaved shrubs and climbers adapted to the three above-mentioned zones. The planter must, therefore, make due allowances for local conditions.
1. Piedmont Zone extends from the Mountain Zone to the Fall Lane, which follows approximately the following cities: Weldon and Raleigh. North Carolina, Camden, and Columbia, South Carolina; Augusta, Milledgeville, Macon, and Columbus, Georgia; Montgomery, Alabama; Columbus and Holly

Ornamental shrubs for California.
No pretensions have been made in compiling the following list to include every plant of desirable ornamental characteristics that will grow in California. Many exotics are being continually introduced, some of which have proved highly satisfactory, while others are little known. The effort has been rather to classify under various subheads those shrubs which are undoubtedly suited for the purpose indicated and which have proved themselves well adapted to the various sections of the state.
Many of the deciduous ornamental plants commonly employed in the eastern United States for landscape planting have purposely been omitted, as they fail to produce the same wonderful spring-flower effects under the different climatic conditions of California. Only such deciduous shrubs as bloom freely and seem to have become more or less adapted to the drier climate of this state are included.Because of the great variety of climatic and soil conditions throughout the state, it has become necessary to think of it as divided into three general regions,—the interior valleys, the San Francisco Bay district, and that part of southern California in the vicinity of the coast.
Those kinds marked with a dagger(+) will thrive only in southern California; those with a star (*) will grow in the South and as far north on the coast as the San Francisco Bay region, while such kinds as have no abbreviation attached will probably grow in all the cultivated areas of the state, including the large interior valleys. With one exception, the shrubs in the lists are arranged in the order of their desirability for the purposes described by the subhead. By cross-reference, the lists should prove helpful in selecting species of certain characteristics for given climatic and cultural conditions to produce the results desired.
Group I. Shrubs which are more or less resistant to conditions created by full shade.
While the larger number of these shrubs will produce the best results in half-shade, or even in full sun if -given sufficient water, they are more or less tolerant to conditions existing under live oak trees, in courts, or on the north sides of buildings.

Group II. Shrubs which thrive most successfully in half- shades in California.
Many plants will produce the best results in full sun if favorable moisture conditions can be maintained throughout the summer, but the amount of sun exposure that plants in this list will withstand depends largelyon the section of the state in which they are located and on the amount of water they receive.Because of neglect aided by the long dry season, they often do better, however, in half-shade where the soil does
not dry out so rapidly.

Group IV. Shrubs resistant to soil and climatic conditions along the California seacoast.
The plants in this list are fairly resistant to the effects of strong prevailing winds and
thrive in dry sandy soils containing more or less salt and are therefore valuable for
windbreaks and shelter plantings. In general, the finer the foliage and the more willowy or
wire-like the branches, the more easily do they withstand the trying conditions. A noticeable
exception is some few kinds of hardy palms which thrive under such conditions because of the
stiff character of their leaves and stems.

Vines for California.
In countries where there is a maximum of sunlight, vines become a most important class of plant-material. The many vines used in California are roughly divided into classes according to the climatic divisions of the state. Tropical and semi-tropical evergreen vines find most favor
in southern California, where gorgeous coloring and luxurious growth appear most in harmony with the landscape; while the half-hardy evergreens and the choicest deciduous vines are most suitable for use along the central California coast. On the other hand, the vine which loses its foliage in winter finds the greatest favor in the interior sections of the state, although such few evergreens as withstand several degrees of frost are often employed for decorative purposes. When very quick effects are wanted, the annual vine is often used.
All vines except those clinging to rough surfaces need substantial support, while most vines require a certain amount of thinning and training. The tendency is to neglect the plant after
it is once established and allow it to form thick unsightly masses of stems near the top of the support, thereby destroying such decorative beauty as the vine may possess. Vines should not be "headed back" or heavily pruned unless the plant is to be renovated, as a coarse rank growth is encouraged. If possible, choose strong stems as leaders and train in a fan-like manner so as finally to cover the desired area. Spring-flowering vines should be pruned soon after blooming,
while summer- and fall-flowering vines may be thinned in the spring. The foliage of evergreen vines may be best reauced by careful selective thinning immediately after a blooming period. Always begin to train a vine as soon as possible; do not wait for it to begin to climb.
No climbing roses have been included in the following lists, as it is felt that they should be considered as a separate class of plant-material. Such vines as are not marked with D" or "A"
are evergreen, while those without an "o" or "x" are hardy. D—deciduous; A-annual; o—not resistant to frost; x—resistant to 10° to 12° of frost.
