places where the cold settled and late growth was favored by rich 
moist soil. In practically all cases trees of these ages made a 
rapid and satisfactory recovery during the summer. 
With peach trees over seven or eight years old the injury was 
found to be far more serious. The discoloration was much more 
pronounced, and increased in intensity with the age of the tree, 
when the other conditions were parallel, being greatest again 
upon trees located in low places and on moist rich soil. The 
older’ trees did not make a rapid nor vigorous recovery. The 
foliage was scanty, undersized and of a pale color—in contrast 
with the younger trees on which the foliage was normal in these 
respects. There were also more small dead twigs scattered 
through the tops of the older trees than there were in the younger 
trees. 
Many pear trees from two to five years old were examined in 
which the bark and wood were badly discolored, the bark being 
filled with brown streaks, instead of a solid color as in the case of 
the peach. The common opinion was that trées in which this dis- 
coloration was marked were practically ruined, and the best way 
would be to cut them off below the snow line, and let them send 
up sprouts from the stump. If there had been time enough in 
the spring for the work, the owner of these trees would have 
treated several thousand of them in this way. But the growing 
season proved the fallacy of the prediction. Lack of time was 
fortunate for the fruit grower. ; 
With but very few exceptions these young trees made a good 
recovery, had a good crop of healthy foliage, made a good amount 
of new wood and enlarged in the diameter of the trunk very 
noticeably. Wire labels loosely fastened on the trees in March 
had, in September, become imbedded in new growth. 
All of these trees were examined again in June, 1905, and 
practically all of them had made a very good recovery. Nearly 
all of the peach trees and many of the young pear trees had a 
good crop of fruit. 
EFFECT OF INJURY UPON TREBS, 
The injury manifests itself in various ways and at different 
times, depending upon the degree. 
In some cases the trees did not show any life at the opening of 
spring, being killed outright during the winter. This was more
