Ions water. The second, solution B, consisted of three ounces car- 

 bonate of copper, one pound carbonate of ammonia, fifty gallons 

 water. 



A number of trees were sprayed four times with each solution, 

 while others in the same vicinity were left as checks. Rain followed 

 soon after each application, and the results were not as striking as 

 might be desired. The average results, however, are slightly in 

 favor of the spra3-ed trees as compared with the unsprayed, while 

 solution A gave slightly better results than did solution B. The 

 percentage of fruit absolutely free from scab, was very low in 

 every case. In a general way, however, the work is of value in 

 that it confirms the results obtained in Mr. Pope's orchard. 



The work carried on in the orchard belonging to our president, 

 Mr. Pope of Manchester, was of sufficient extent to warrant very 

 free conclusions, from a commercial poi..t of view. The or:!hard is 

 situated on a gravelly hill-side, having a northwestern exposure, and 

 instead of single isolated trees being given different treatment, 

 contiguous rows, extending down the hill- side were selected. In 

 this way all of the rows presented essentially the same conditions, 

 pait of the trees being on high land and part on low. 



In addition to the two solutions used in Mr. Moore's orchard, a 

 third — the modified eau celeste described last year was used. The 

 formula for this solution was as follows : Two ponnds sulphate of 

 copper (''Blue Stone") ; two and one-half pounds carbonate of 

 soda ; one and one-half pints ammonia ; thirty gallons water. 



To be doubly sure of results, duplicate series were used. In 

 this way we have two rows in different parts of the orchard sprayed 

 with each solution ; while for comparison three rows, alternately 

 with these, were left without treatment. 



The following diagram shows the relative location of the sprayed 

 and unsprayed trees :
