ing of wheat greatly influences amount of “scab;” that planted late, and 
hence blooming late being worst affected. Considers vigorous growth and 
early blooming the chief safeguards against the disease. (D. G. F.)

Agric. Ex. Sta., N. Dak., No. 4, Fargo, Dec., 1891, pp. 15-17, pi. 1. Describes 
disease and states it seems to he the same as that affecting potatoes. Oc¬

Sept., (Nov. 7,) 1891, pp. 212-214. Gives result of investigations made in 
Dakota, in which the fungus characterized by Thaxter is found undoubtedly 
genetically connected with the disease. Considers it possible that his pre¬ 
vious year’s investigation may contain errors and acknowledges the supe¬ 
riority of Thaxter’s fungus as a scab producer. (D. G. F.)

Sta., N. Dak., No. 4, Fargo, Dec. 1891, pp. 1-14, 21-31, pi. 1, figs. 4. Discusses 
nature of potato scab, giving theories in regard to cause. Considers dis¬ 
ease due to parasitic fungi and describes effects. Gives report of experi¬ 
ment for prevention of disease and recommends selection of sound potatoes 
for seed; gives also formula for treating seed before planting, as follows: 
Corrosive sublimate, 2 oz., dissolve in 2 gallons of hot water and leave all 
night; dilute with 13 gallons of water, stir thoroughly and immerse pota¬ 
toes to be used for seed in mixture for 1| hours; dry potatoes, cut and plant 
as usual. In appendix to article gives table of tests of effects of character of 
soil on the origin of the disease, together with statement of treatment adopted 
for prevention. Discusses the difference between surface and deep scab, leav¬ 
ing the subject in doubt as to whether the diseases are distinct or different 
forms of the same. (J. F. J.)

nose of the tomato, caused by Colletotrichum ly coper sici, n. sp. (2) A leaf 
spot of celery, possibly caused by a new species, in which case it might be 
named Septoria apii. (3) Blight of watermelon vines caused by Phyllosticta 
citrullina, n. sp. (J. F. J.)

“rust” of cotton appearing in the Erivan district in 1888 after a wet sum¬ 
mer. The disease had never before been observed on the plant known 
locally as “ Kara-kosa,” but in some localities it destroyed nearly one-half 
the crop. (J. F. J.)

potatoes, the one of scabby tubers and the other of healthy ones. Con¬ 
cludes harvest from planting of healthy tubers, though partly scabby, bet¬ 
ter than the harvest from the planting of scabby tubers. (D. G. F.)
