The blocks were selected in such a way as to overcome any lack of 
uniformity in the character of the soil. For example, part of Block 1 
was situated at the northwest or highest corner of the plat, while part 
was at the southwest corner, nearly 600 feet distant, where the ground 
was low and inclined to be moist. 
It will be seen from the foregoing table that part of the stocks re- 
ceived seven treatments, part received six, and the rest received five. 
Those receiving six sprayings were treated first May 19, when the other 
blocks were being sprayed the second time. The reasons for adopting 
this plan may be briefly stated as follows: 
(1) To ascertain the effects of early treatments. 
(2) To determine the effects of treatments up to the time of budding 
as compared with those continued for a month or longer after the buds 
lad been inserted. 
Before proceeding with the results in detail it may be well to call 
attention to the preliminary nature of this report. The work of 
course, in so far as it relates to the first season, is complete. But it is 
possible that as the treatments continue the results may be somewhat 
modified. Keeping this point in mind, the work will now be taken up. 
First treatment (May 5).—At this time the stocks were all in good 
condition, having been planted about three weeks before. The leaves 
on the pears, cherries, apples, and plums were just beginning to un-
