described bacterial disease which attacks sweet corn only, and 

 principally the early dwarf varieties of sweet corn. It makes 

 its appearance eariy in the season, stunting and often killing 

 the plants while they are forming ears, whereas the Hel- 

 mintJiospoHum disease usually do<'S not appear until the month 

 of August. 



The Helminthosporium disease has rarely been reported as be- 

 ing injuriously abundant, but on Long Island it must be regarded 

 as an enemy of considerable importance. Dr. Thaxter* reported 

 it abundant in Connecticut in 1889. 



No practical remedy can be recommended. 



Norway Maples Injured by Dry WiNos.f 



About May 25, 1895, the Norway maples {Acer platanoides) 

 on Long Island presented an appearance which puzzled observant 

 persons. The entire foliage, even of large trees, looked as if 

 it had been scorched by fire or killed by heavy frost. But since 

 there had been no frost for at least three weeks, the phenomenon 

 was at first thought inexplicable. However, the fact that the 

 trouble was a general one, and appeared suddenly, suggested 

 the idea that some unusual condition of the weather was re- 

 sponsible for it. Such was, in fact, the case. For a period of 

 about a week previous to the appearance of the trouble the tem- 

 perature had been unusually high for the time of year, and for 

 at least three days very strong, dry winds had blown steadily 

 from the west. The leaves of the Norway maples were about 

 half grown at this time and very tender. The hot, dry wind 

 caused the leaves to transpire water more rapidly than the roots 

 could supply it, the consequence of which was the death of the 

 leaves. It was observed that some trees suffered more than 

 .others, and trees recently transplanted were burned most se- 

 Terely of all. The explanation of this is, that trees in sheltered 

 positions transpired less water, and, consequently, suffered less 

 than trees exposed to the wind; and trees newly transplanted 

 were not able to supply their leaves with water as rapidly as

t Since this article w.is written Dr. Stone has reported a similar injury to siisar maples 

 {Acer saccharinum) in Massachusetts, in May, 1896. His theory as to the cause of the trouble 

 is the same as the one here a.ilvanced. See Ninth Ann. Rept. of the Hatch Exp Sta of Ma.ss
