This table shows a slightly greater injury in 1895 with the 

 untreated Baldwins, a greater injury with untreated Fall Pip- 

 pins in 1895, with untreated R. I. Greenings in 1893 and 1894 

 and with Boxbury Raissett in 1893 than with the treated trees of 

 the same varieties. With these exceptions these varieties show 

 on the average every year greater injury from scab where the 

 ground was fertilized with ashes than on corresponding sections 

 which received no ashes. 



In 1896 the season was unusually favorable to the development 

 of perfect fruit, yet with every one of these varieties, the records 

 show a greater average injury from scab on treated than on 

 untreated sections. If apple trees ever needed to be fortified 

 against conditions unfavorable to healthy growth it was in the 

 early summer of 1894, yet in that year, with the exception of R. 

 I. Greenings, every variety named in the table had a higher rate 

 of injury Mhere ashes were used than where they were not used. 



This orchard had been sprayed with London purple only, and 

 even in sections treated with the ashes had in some cases lost 

 over half of its foliage from an epidemic of fungous diseases and 

 other injuries following the long period of dark, cool, wet 

 weather. In marked contrast was an adjoining orchard that 

 had been treated with Bordeaux mixture to prevent the scab 

 and whose foliage had been kept in good condition by this means. 

 In the orchard where the ashes were used much of the fruit 

 dropped in June as a result of the loss of the foliage, while the 

 trees which were sprayed with Bordeaux mixture held both the 

 foliage and the fruit and matured a fairly good crop. The great 

 superiority of the Bordeaux mixture for preventing the scab 

 under most unfavorable conditions, as compared with fertilizing 

 the soil with ashes for the same purpose, was thus clearly shown. 



CONCLUSIONS. 



The investigation has extended over a period of five years, it 

 has included forty-seven trees in full bearing in the treated sec- 

 tions, comparable with the same number of trees representing 

 the same varieties in the untreated sections. The results show
