ing he found a total of 193 infections, 151 of which were leaf 

 infections which had not yet entered the stem. 



THIRD SEASON. 



In 1909, also, there were four primings made on the following 

 dates: May 19, June 16, July 11 and August 18. The first 

 priming, on May 19, might better have been made on May 15. 

 Considering the care with which the pruning had been done we 

 were surprised to find that a good many canes were killed clear to 

 the ground and the fungus had gained access to the crown of the 

 plant. Four plants with single stems were entirely dead. Fifty- 

 two diseased canes were removed in the second priming and 69 

 in the third. The first priming required two hours and forty- 

 five minutes ; the second, one hour and five minutes, and the third, 

 one hour and fifteen minutes. 



FOURTH SEASON. 



This year priming was done on May 2, June 6 and July 6. 

 The spring was an unusually early one. At Milton, currants 

 were in half bloom by April 18. Beginning with the first prun- 

 ing of this year a single row was pruned at each passage through 

 the field. Owing to the increased size of the plants it was found 

 difficult to manage two rows at a time without overlooking 

 some of the diseased canes. The time required for the first prun- 

 ing (including removal of the primings) was two hours and 

 twenty minutes. Plats IV and VI each yielded one large arm- 

 load of primings while on Plat II there were more than could 

 be carried at a single load. It was thought that time might be 

 saved by putting the primings into a large muslin bag slung over 

 the shoulder, but a brief trial showed this method to be quite 

 impracticable. Some of the affected canes were so large that they 

 could not be put into the bag readily. This year, for the first 

 time, the yield of fruit was measured. The three primed plats 

 yielded 2,402 quarts (3,193 qts. per acre) while the total yield 

 of the three check plats was 2,481 quarts (3,296 qts. per acre).
