culty was experienced in treating the upper portions of the trees. 
In attaining this end the lower branches were repeatedly drenched 
with the wash and were much oversprayed. The precipitation 
following the operations was as follows: April 18, 14 and 15, 
heavy snow during the afternoon and evening; April 19, heavy 
snow followed by rain; April 20, rain all day; April 24, light 
Showers in the afternoon; April 27, rain in the. afternoon and 
evening. The bordeaux-arsenical mixtures were applied April 
12, June 1 and June-14. The second application with this spray 
was made just as the petals were dropping, for the purpose of 
controlling the codling moth. 
Effects of sulphur sprays on trees.—On May 10, the buds were 
opened and the leaves were appearing in clusters. At this time 
it was evident that the treatment of the lower branches had 
reduced the number of buds, but it was hardly possible to deter- 
mine the exact nature or the full extent of the injuries. By 
June 24 when the leaves and fruits were well developed the effects 
of the spraying were more plainly marked; for the lower por- 
tions of the sulphur-treated trees had relatively less foliage and 
fruit than like areas upon the untreated trees. The sprayed 
trees as a rule bore their crops on their topmost branches while 
with the unsprayed trees there was usually a more even ‘distribu- 
tion of the fruit. The sulphur-treated Baidwins had on the aver- 
age much smaller yields, than the untreated trees. The Greenings 
did not set as heavy a crop, and the yields of the sulphur-sprayed 
trees were on the whole not as large as those of the unsprayed 
trees. On October 16 the fruit was picked and counted. The 
yields are as follows:
