Give preliminary report upon a bacterial disease of young grape clusters found in June, 
1891, at several localities near Modena. The disease is manifested by a brown coloring and 
final drying pp of the stems and pedicels of the young grapes and a consequent wilting of 
the immature berries. The organism (3-4 by 1-1J y), cultivated on gelatin, gives honey- 
yellow colonies with indefinite contours, which rapidly become continent and liquefy the 
medium; also grows on potato, giving same colored colonies, but with sinuose margins. 
Find the bright yellow color to fade out upon extended cultivation in gelatin. No inocula¬ 
tions were reported on, but it is the intention of the authors to work out the life-history of 
the parasite. Think the malady likely to prove a most serious one. (D. G. F.)

Describes a disease observed in Alabama due to Thelephora pedicellata Schw. Recommends 
cutting out diseased wood, washing with copperas or sulphate of iron, and coating wounds 
with wax or similar substance. This treatment was successful when tried. (J. F. J.)

Discusses question of the presenco of the black rot in Italy, deciding it to have made its 
first appearance in 1891, notwithstanding a previous report in 1877 by Arcangeli. Doubt is 
thrown on its correct identification by the fact that only the foim on the leaf has been found. 
Refers to work of Viala, and especialty to experiments of Galloway. (D. G. F.)

Discusses various diseases of sugar beet observed both in Europe and America. These are 
beet rust, caused by TJromyces betee; white rust of beets, caused by Cystopus bliti; spot dis¬ 
ease, caused by Cercosporct beticola; root-rot disease, caused by Hematode worms; violet-root 
fungus, caused by lihizoctonia betee , and also by species of bacteria; scab of beets, caused by 
bacterial germ as shown by Bolley. The life history of these species is given. In summary 
states that spot disease can be checked by Bordeaux mixture or ammoniaeal carbonate of 
copper. Beet scab and potato scab seem to be the same, and the two crops should not follow 
one another. They are liable to be carried from a diseased field to one not infected. [Re¬
