Believing that the foregoing clearly sets forth the plan of the ex- 
periment, the work will now be taken up in detail. 
First treatment (April 14).—Two trees in each plat were sprayed 
with each of the ten fungicides, a Nixon Little Giant force pump pro- 
vided with Vermorel nozzle being used for the purpose. The flower 
buds were not open and only a few leaves had started. Heavy rains 
had fallen previous to the spraying, making it difficult to move the 
spraying machine about. No scab or leaf-blight whatever: was ob- 
served. Most of the trees gave promise of an excellent crop, flower 
buds being very abundant. 
Second treatment (April 25 ).—The two trees in each plat were again 
sprayed at this time, and in addition a third tree in each plat received 
its first spraying. Owing to the small quantity of fungicide used, the 
Galloway knapsack pump was substituted for the Nixon cart machine. 
This pump, which was provided with a Vermorel nozzle having a lance 
4 feet long, did its work well, the tops of all the trees being easily 
reached. 
At this time the leaves were about one-third grown and the flowers 
had for the most part disappeared. No rain of consequence had fallen
