Pots. Of the three firms of interest to horticulturists that are eligible to the Century Club because of one hundred years or more in the same business, are A. H. Hews & Co., potters, and J. M. Thorburn & Co., of New York, and D. Landreth & Co., of Philadelphia. This indicates the age of the flower-pot business in this country.

Until about 1864 or 1865, common flower-pots throughout the world had always been made by hand on the potter's wheel. There have been, indeed, many different forms of this wheel, but it had always been propelled by hand- or foot-power. When, in the early fifties, a wheel was made to be propelled by the foot, with two sizes of pulleys and a balance-wheel whereby the speed of the wheel was increased in the proportion of three to one, it was thought that perfection had been reached. Much time, though very little money, had been spent previous to the fifties in attempts to make a pot machine. It was left to William Linton, of Baltimore, an experienced practical potter, to perfect and patent the first machine. From him two machines were purchased and the exclusive right to use them in Massachusetts. In a short time great improvements were made on his patent. America was far ahead of Europe in this kind of machinery, as also in improved machinery in general. The machine made only small pots, up to about 5 inches in diameter; and while it had previously taken an experienced man to make his thousand 3-inch pots in ten hours, a smart boy without any previous experience whatever could make 3,000 on the machine in the same time.

When the standard pot was adopted, about twenty- five years ago, the hand-process was practically abandoned in the principal potteries in favor of what is technically called the jigger. This is a revolving disc propelled by machinery. These discs, or jigger-heads; are made of different sizes and fitted with various rings. Plaster molds are made in very large numbers for each size of pot, and the larger standard pots (6- to 12-inch)

The making of the pot is not its only cost: previous to that comes the preparation of the clay. The hundred years from 1765 to 1865 saw no improvement in the process of preparing it for use. It was ground in a wooden tank or tub, propelled by an ox. The various other processes remained as crude in 1865 as they had been the century previous: the drying, firing, and all connected with the manufacture. The capacity of our flower-pot drying-rooms of today far exceeds the

From the drier, the clay goes into large bins, where it must remain twenty-four hours, so that portions of it which have become too dry and hard may absorb the moisture from that not dry enough. From these bins it is carried to whippers, which beat the clay without further crushing the stone. From the whipper it goes to the revolving screens, and thence to the elevators.

The next process is mixing, or, as it is termed, "pugging." This is all done by machinery. From one machine the clay comes out very soft and plastic, to be worked in plaster molds. From the other the clay comes out into hard cubes for the irom molds of the machine. The pot machine and the jigger of today each does the work of six to eight men at the wheel.
The difference in cost between a good and a poor pot is very slight, and if the florist will demand and accept nothing but a first-class pot, a standard in quality as well as size will soon be reached. To be standard in quality a pot must be of clay properly prepared, be of uniform firing, and of a smooth surface inside as well as out. It must also be of right porosity, a condition which can be attained by the proper mixture of clay. Moreover, a machine-made pot should have a smooth run on the inside, so that the man standing at his bench potting thousands of plants a day, as is being done constantly in large establishments, may have flesh remaining on his thumbs at night. Such a pot must also be able to stand transportation and years of usage if necessary. "Standard flower-pots, such as are now used by American florists, are shown in Figs. 3160, 3161. A. H. Hews.
