fspet'ilic siravity varied from 1.001 to 1.071. A fornnila containinjj 25 lbs. lime, 20 

 Ihs. sulphur, and 20 11)^=. Hulphate of copper per 100 gal. water gave excellent results. 

 As a result of these tests and other experiments with this mixture the author recom- 

 mends in general the following forintda: Lime 30 lbs., sulphur 80 lbs., salt 10 lbs., 

 water 100 gal. As a winter wash llic author recommends 2 treatments, one in 

 November or December and the other in February or March. 



Experiments were also made in applying this mixture to the trunks and branches 

 of trees in July, August, and September. As a result of these experiments the 

 author reconunends lime-sulphur wash as a summer treatment for apple trees, and 

 believes that it may prove safe for peach and other fruit trees.
