'■'•Results. — The copper solutions remained persistently on the 

 leaves, even resisting heavy showers, which washed off all traces 

 of the sulphur compounds, and when the leaves fell in October 

 traces of copper could still be see on them." 



"At time of harvesting Professor Taft picked all the apples on 

 the trees and assorted them into three lots, of first, second, and 

 third quality . The first class contained those free from scab, the 

 second those slightly scabby but not distorted or under size, the 

 third those that were distorted or under size. Those in each class 

 were counted and the percentage which they formed of the whole 

 estimated. 



"At Ithaca, Wis., the apples were not all picked, but a market- 

 basket holding about 1^ pecks was first filled with apples from the 

 lowest branches of one of the trees. Next a similar basketful was 

 picked from the branches that were just the height one could con- 

 veniently reach, taking care to pass clear around the trees in both 

 cases. After this a basket of one-half a bushel was filled from the 

 tallest branches of the tree. The apples were then poured upon an 

 assorting table ; and the baskets filled and emptied again in the 

 same manner and from the same tree, after which the contents of 

 the six basketfuls were assorted into three qualities as in the pre- 

 ceeding case." 



"Jt is evident from the tables that the sprayed trees, especially 

 those sprayed by copper compounds, producing a much larger per- 

 centage of healthy fruit than the unsprayed. The greatest differ- 

 ence between the perfect fruit on sprayed and unsprayed trees 

 under Prof. Goff's charge was i^l.fiS per cent, and the least (i.7
