Experiment II. 

 The orchard of Mr. H. S. Wright, upon 

 wliich this experiment was made, is situ- 

 ated quite apart from other orchards of its 

 kind, on the slope of West Hill, Ithaca, 

 two or tliree hundred feet, perhaps, above 

 the level of the principal portion of the 

 city. It consists of youug trees and suf- 

 fered badly from curl in '98, but has not 

 been sprayed until the season just passed. 

 Elberta and Early Crawford varieties are 

 about equally represented, the latter occu- 

 pying mainly the southern portion of the 

 block. The trees matured a good crop of 

 fruit. Following the table of results by 

 rows, is given one sliowing the comparative 

 effectiveness of the solutions used.
