LIME-SULPHUR MIXTURES FOR SUMMER SPRAYING. 15 
Examinations made in August and September revealed very little 
change in the condition of the various plots. The trees of plots 1, 5, 
and 6 held a full crop of foliage throughout the season,® and very little, 
if any, difference could be observed in these plots. The self-boiled 
lime-sulphur mixture (10-10-50), the factory-boiled lime-sulphur 
solution (1-40), and the Bordeaux mixture (2—4—50) were equally 
effective in controlling the cherry leaf-spot. The trees in plot 
2, which were sprayed with the weak (6-6—50) self-boiled lime- 
sulphur mixture, held up almost as well, but the mixture was evi- 
dently rather too weak for the best results. Most of the check trees

same date as that shown in figure 1. 
put out three or four leaves at the tips of the twigs, and a few blos- 
soms appeared from time to time during August and September. 
APPLE-SCAB EXPERIMENTS. 
On account of the extremely urfavorable weather conditions the 
apple experiments were unsatisfactory and the results not at all 
conclusive. To determine the relative merits of self-boiled lime- 
sulphur mixture (10-10-50), factory-boiled lime-sulphur solution 
@In arecent letter Mr. Aldrich stated that the sprayed trees held their foliage 
until frost.
