A recent bulletin I Xo. 35 ] of the Rhode Island Experi- ment Station describes and illustrates a modilication of the absorbing-block idea. Instead of a slab of stone or earthenware, "sprouting cups" are used. "These were made fir this station out of ponms clay by A. H. Hews >.S: Co., of North Cambridge, .Mass., the pattern being nuK h like that used at the Seed Control Station at Zurich, Switzerland. They are 3 inches in diameter and i^ inches high, including the cover, which is ven- tilated, as shown in Fig. 13. The bottom is solid and '2-inch thick. Each cup is placed in a glass dish in which a constant supply of water is ; These cups are placed in a " Sjirouting chamber" (Fig. 141, supjilied with unif)rm heat. "This about llt'ly cups. Ileat is su]iplied l>y a gas jet, which is supported beneath the chamber, and it is tlistribiUed evenly to all sides of the chamber, except the front, by means of ;i water-jacket. It is pro- \"ided with two doors, the inner one being glass. There is an oix-ning in the side and tup for \-ent\lating, and a second opening in the tup for the insertion of a thermum- eter. There are also two openings into the water-jacket.
