rain, it was impossible to follow the prearranged plan for spray- 
ing, and much difficulty was experienced in applying thorough 
treatments to the trees. 
With the opening of the buds there were marked differences 
in the trees under the same treatment. This variation was shown 
in the color of the leaves and in the relative amounts of foliage 
and fruit, and was noticeable in all of the four sections. These 
results did not appear to be occasioned by this season’s treatment 
but were apparently due to the ill effects of last year’s spraying 
with bordeaux mixture. In the summer of 1903 applications of 
this mixture caused severe injuries to the foliage; and it is rea- 
sonable to suppose that the accompanying defoliation, probably 
coupled with injuries by the severe winter following, was ‘largely 
responsible for the condition of these trees. With the picking 
of the fruit on September 27 the apples were carefully examined 
with respect to scale, codling moth and scab, the results. being 
tabulated as follows:
