1898, but the more susceptible varieties have suffered considerably. 
It is well known that varieties differ greatly in their susceptibility 
to leaf blight. At Poughkeepsie the variety Gandy was severely 
attacked, while the variety Clyde growing in adjacent rows under 
parallel conditions was almost entirely exempt. 
At Ghent we had an opportunity to observe the disastrous effect 
of leaf blight upon the crop of the following year. A row of Hunn 
stood beside a row of Parker Earle. In 1898 the Hunn blighted 
very severely while the Parker Earle was but slightly affected. 
On June “%, 1899, the Hunn promised a very trifling yield. Many 
of the plants did not even start in the spring. In marked con- 
trast to the condition of the Hunn, the Parker Earle was making 
the best showing for a berry crop that we have ever seen. 
It may be that some of our correspondents have confused the 
leaf spot caused by Sphaerella fragariae with that caused by Asco- 
chyta fragariae Sacce. The two diseases resemble each other 
considerably, but the Ascochyta spots are redder and show minute 
black pimples at the center. On May 31 we collected fruiting 
specimens of the Ascochyta at Athens, Greene Co., but we do 
not believe that it was anywhere as abundant as the Sphaerella. 
SUN-SCALD ( ?) 
On June 2 we observed at Ghent a peculiar disease on the 
Hunn strawberry. The leaflets showed dead, brown V-shaped 
areas at their tips (see Plate XVI, fig. 2). These dead areas often 
extended half way down the midrib. They were generally situated 
at the tip of the leaflet, but occasionally occurred at the side. 
The disease occurred only on the Hunn, on which it was com- 
mon but not destructive. It did not appear to be due to fungi 
and certainly not to insects. We are at a loss to account for it 
unless it may possibly have been a case of sun-seald.
