Conclusions drawn from such limited data would be coaonle é 
incorrect, inasmuch as the differences noted are not sufficient to 
B overcome individual traits. The difference in the amount of acid 
i present 1 in Fay’s Prolific differently fertilized is within the limit of 
; _ error in analysis, while it is worthy to note that in the case of 
oy dry matter and sugar content the precentage is higher in those 
a fertilized with the sulphate. Whether the differences are due to 
the influence of the fertilizers used, it is impossible to state at 
this stage of our investigations. 
GOOSEBERBRIES. 
Much interest has been manifested in the results obtained at 
this Station, in preventing the mildew from destroying the goose- — 
berry crop, and as each season gives more positive proof that the — 
| application of potassium sulphide is a sure preventive, the time | 
seems not far distant when this fruit will be again generally 
grown in marketable quantities. 
The following varieties were fruited here this year: 
Crown Bob, Smith’s Improved, 
Crystal, Triumph,

At fruiting time the product of one plant of each variety was 
weighed, and, with the exception of Crown Bob, each gaye over
