The photographs in this article illustrate the difference in the two forms of Arsenate of Lead: one is Sherwin- Williams New Process Arsen- ate of Lead, which is the highest type of an absolutely neutral, thoroughly combined lead arsenate, and the other is one of the typical brands of acid Arsenate of Lead offered in competition at a much lower price, which shows very clearly the defects common to this form of Arsenate of Lead. In the illustration shown by Fig. 1 we have a picture of these two forms of Arsenate of Lead stirred up in water and allowed to settle for fifteen minutes. The same quantity of paste is used in each case and diluted to the same total volume with water. Fig. 2 shows them after they had stood over night and settled all they could. After thoroughly settling, the bulk occupied by a given quantity of S-W New Process Arsenate of Lead is approxi- mately 45 cubic centimeters, whereas the competitive ma- terial, in the acid form, is 20 cubic centimeters, showing two and one-quarter times the bulk for New Process Arsenate of Lead. The facts given above plainly show the inadvisability of the orchardist using the cheaper grades on ttte delicate foliage of his fruit trees. There's no need to take chances. Use the best.
