Survival of Storm-Injured Leaves—During the last summer it was 
frequently remarked that the late spring frosts had seriously injured 
the young foliage, several gentlemen having commented upon the dam- 
age thus wrought to their shade trees. My attention was first attracted, 
on May 27th, to the wilted appearance of the leaves of a white oak on 
Richmond terrace, near Stuyvesant place, and later to the similar con- 
dition of the Norway maples on DeKalb street. A search for para- 
sitic fungi as the cause revealed nothing, and it was not until a gar- 
dener suggested the wind that the true explanation appeared. This, 
perhaps, should have been more apparent, although few seem to have 
suspected the real cause. The damage was so general that it con- 
tributed a conspicuous feature to our summer’s foliage throughout our 
eastern and southern exposures, as has already been incidentally men- 
tioned in the Proceedings for October in connection with the effects 
upon the Cicadas. 
The storm, which lasted several days, began on May 20th, and the 
trees then in foliage all suffered more or less, the extent of damage 
seeming to be proportional to the size of the leaves. The white oaks 
and the maples having the largest leaves at that season, were lashed 
and bruised in a somewhat interesting, if not remarkable, manner. 
Fruit trees were also considerably injured. Few, if any, leaves were 
killed. They seem rather to have been injured in spots, chiefly at the 
tips, though also along the edges and through the blades of the leaves, | 
extending inward from the sinuses, withering at these points while the 
remainder of the surface was unharmed. Some were split radially 
along their weakest sections, withering on the edges of the split. In 
some, over three-fourths of the surface was killed, the shape, however, 
being preserved intact, the other fourth remaining green and healthy. 
It is difficult to describe their appearance, but the specimens submitted 
will indicate the peculiar way in which they were affected by the injury. 
The general appearance of the trees has been too common all summer
