CERCOSPORA (?) ON PEACHES. 
Badly spotted Crawford Early peaches were received from A. A. 
Crozier, Ann Arbor, Mich., and later in the year the same disease was 
observed by the writer on other varieties at Douglas and Benton Har¬ 
bor, Mich. In the specimens from Ann Arbor the spots consisted of 
small, roundish, slightly elevated portions, with a dead, yellowish cen¬ 
ter, and a dark, purplish brown circumference. In the most typical 
specimen, not over one-eighth of the surface was pitted, but that bore 
50 spots, giving to the surface a very measly appearance. The central 
dead portion of the spot did not exceed a diameter of one-half mm. 
.and often it was less. In the specimens collected at Benton Harbor a 
central white spot was surrounded by dead, brown tissue, which was 
ringed in turn by deep crimson. There was a mycelium in the spots 
suggestive of Cercospora circumscissa , but all of the spots were sterile 
and the fungus Avas excluded from the living tissues by a thick layer 
of cork. 
Comparatively few fruits were attacked, and this is the first time 
anything of the kind has come to my notice. 
PEACH MILDEW.* 
A variety called Arkansas Traveler mildewed badly on the farm of 
William Smithson, at Youngstown, N. Y. No other variety in the 
orchard was attacked, and no other was destitute of glands at the base 
of the leaf blade (see Jour, of Mycoh, vol. vn, p. 90). As heretofore, 
no perithecia were found in connection Avith this mildew, even when 
the examinations were continued until winter, and its identification is 
still doubtful. 
PEACH CURL, t 
Peach curl Avas rather severe in southwestern Michigan along the 
lake shore. On uplands, some miles away from the lake, it Avas less 
prevalent. 
The sudden appearance of this disease under conditions such as were 
described in Field Notes, 1891 ,\ i. e., following a decided drop in tem¬ 
perature, is due, according to N. A. Cobb, solely to unusual deposits of 
dew, prevaling at such times, and affording special facilities for the 
germination of the spores and the entrance of the fungus. 
WILTING OF PEACHES ON THE TREE. 
At Benton Harbor, Mich., during a few days preceding September 
22, many Hales Early peaches partially separated from their peduncles 
and shriveled, and even fell from the trees. This was just in advance
