164 Report oF THE BOTANIST OF THE 
Accurate information is lacking as to the susceptibility of dif- 
ferent varieties. Montmorency” has been more commonly af- 
fected than any other variety, but English Morello and some 
other varieties have shown it to a considerable extent. 
From the experience of Maxwell Bros., it would appear that 
little harm is hkely to result from this scorching of the foliage, 
but it seems incredible that a cherry tree can lose a large part of 
its foliage in July or August without affecting its productiveness. 
The effect must be the same as if the leaves were removed at this 
time. We shall watch the Maxwell orchard with interest the 
coming season. 
LEAF SCORCH, OR TIP BURN, OF CAULIFLOWER. 
On September 1 Mr. I. A. Sirrine, Entomologist at our Branch 
Office on Long Island, sent to the Station some cauliflower leaves 
the margins of which were blackened and shriveled. The di- 
seased leaves were accompanied by a letter saying that throughout 
eastern Long Island the partly unfolded leaves of cauliflower 
were quite generally affected in this manner. On September 7, 
in company with Mr. Sirrine, the writer visited-some of the af- 
fected cauliflower fields in the vicinity of Mattituck. At this 
time the affected leaves were growing and appeared normal ex- 
cept for their crisp, brown or black margins. ‘The newest leaves 
were entirely free from the trouble showing that the cause of 
the blackening was not then active. It was quite plainly another 
case of leaf scorch. 
Large plants were more severely injured than small ones. The 
worst affected field observed was one in which the plants were 
very large and thrifty and had commenced to form heads.° 
As with the beet and cherry, the exact time the injury occurred 
is unknown. It occurred some time during the last ten days of 
August. Although the rainfall for August in this section was
