upon trees treated with the self-boiled lime-sulphur-caustic soda 
wash; no fruits and 43.3 per cent. of a crop of leaves upon trees 
treated with the boiled lime-sulphur-caustic soda wash. 
Beginning with July 10, there was a very apparent decline in 
the condition of many of the checks. The little growth that had 
been made upon such trees was commencing to drop its leaves. 
The remaining trees were making a good growth and from 
external appearances were as thrifty as the sprayed lots. On 
August 1, twenty of the checks were dead, and thirty-two were 
shedding their fruits and leaves. Likewise two of the trees treated 
with the self-boiled lime-sulphur-caustic soda wash had suc- 
cumbed, and one tree in each of the lots sprayed with the boiled 
lime-sulphur-salt wash and the boiled lime-sulphur-caustic soda 
wash respectively had considerable dead wood. The condition 
of the remaining sprayed trees appeared to be entirely satis- 
factory, with the exception of the fruit. The new growth and the 
amount of the foliage was fully equal to if not better than 
that of the average check. 
The results obtained in this orchard show that there was more 
or less injury done by the winter, although the external appear- 
ance of the trees did not show such during the spring or the 
early summer. In case of the treated trees the effects of the 
sprays were apparently to aggravate the evil consequences of a 
destructive winter, while the loss of a goodly portion of the 
fruit blossoms by the applications served in turn to promote the 
recuperation of the trees. The behavior of the checks would 
indicate that their attempt to mature a crop of fruit was, for 
them in their weakened state, a severe tax, and, in many instances, 
a fatal drain upon their depleted vitality. 
On plums.—Observations upon these trees during the latter 
part of April showed that there were differences in their con- 
dition which varied according to the spray applied. The buds of 
the treated trees were delayed in opening about the same length 
of time as the peaches. At their appearance it was clearly appar- 
ent that the blossoms and the leaves upon the sprayed trees were 
uniformly less numerous than upon the checks, and that there 
was a rather definite relation between their numbers and the 
spraying mixture employed. The conditions of the trees at this 
date, May 12, are shown by the appended table which was con-
