HALSTED, BYRON D.: Field experiments with beans.— 
Beans grown for the third successive crop upon a plot of 
ground (one-tenth acre) gave 25 per cent. of pods that were 
spotted with anthracnose. An adjoining plot of the same 
size as the first and in every way similar except that it had 
borne no previous crop of beans, gave only six per cent. 
of spotted pods. 
OVILLE, F. V.: Crimson clover hair-balls.—These balls, 
measuring two or three inches in diameter, were taken from 
the stomach of horses, whose death they had caused. They 
were compact, and much resembled the hair-balls often found 
in stomachs of ruminants, but were entirely composed of the 
small barbed trichomes from the mature calyx of crimson 
clover (Trifolium incarnatum). ‘ 
OOK, O. F.: A peculiar habit of a Libertan spectes of 
Polyporus.—This species produces long stipes, each succes- 
sive one starting from the upper portion of the preceding one, 
or even from the pileus, in a proliferous manner. This con- 
tinues until the plant becomes top heavy, and falls over upon 
the ground. Specimens were shown. The habit enables the 
fungus to lift the pileus well above water during the wet 
season.
