The trees sprayed with London purple suffered much. All the 

 leaves which were full grown at the time of application fell off, 

 and as the young leaves are comparatively few late in June, and the 

 growth slow, the trees presented a sorry appearance. Fig. 2 is a 

 good illustration of one of these trees about three weeks after treat- 

 ment. The young wood also became spotted, and it assumed a 



deep red color. 

 Many of the shoots 

 were killed outright, 

 and some of the trees 

 are permanently in- 

 jured. The trees 

 sprayed with Paris 

 green shed a large 

 part of the full grown 

 leaves, but no twigs 

 were seriouslv in- 

 jured. Trials with 

 Paris green were furt- 

 her made in lot 10.

 were sprayed with the

 ilar mixture which had stood fifteen hours. The trees were all 

 equally injured in both lots. A week after the application the full 

 grown leaves were all discolored, but none had fallen. Subsequently 

 they all fell. No twigs were injured. A number of very vigor- 

 ous young Russian Apricots were sprayed at the same time with 

 the colored liquid. The foliage was considerably injured, per- 

 haps a third of the full grown leaves falling, but the injury was 

 not apparent so quickly as in the peaches. Over three weeks
