113. Arthur, J. C. Treatment for smut in wheat. Bull. 32, Vol. II, July, 1890, pp. 1-10, 
Indiana Agr. Exp. Sta., La Fayette, Ind. Gives tests of vitality of seed 
wheat after treatment with Jensen liot-water method for smut. Finds 66° 
C. as maximum temperature at which the vitality of the seeds is retained 
and immersion for five minutes in water at a temperature of 57° C. to give 
the largest percentage of uninjured grains, considering high temperature. 
Recommends lengthening time of immersion with lowering of temperature 
and vice versa. No test of the method as to preventive power against smut. 
Gives percentages of stalks smutted with loose smut in counts of two varie- 
ties as 11.58 per cent, and 24.41 per cent. 
114. -- and Bolley, H. L. The specific germ of the carnation disease. Bot. Gaz., 
September, 1830, Vol. XV, No. 9, p. 231 Abstract of paper read by title 
before A. A. A. S. Botanical Section, August 19, 1890. Indicates demon¬ 
stration of bacterial disease. 
115. Atkinson, Geo. F. A new Ramularia on cotton (with figures). Bot. Gaz., Vol. 
XV., No. 7, July 22, 1890, p. 166. Describes and figures as new, Ramularia 
areola, n. s. on cotton, which differs from R. serotina and R. virgaurew in having 
stouter couidia and hyplnn. 
116. Bailey, L. II. Report on the condition of fruit-growing in western New York. Bull 
XIX, August, 1890, Cornell Agr. Exp. Sta., Ithaca, N. Y., pp. 45-58 (with figs) 
Notices as particularly abundant in 1890: Fusicladium dendriticum, (Wallr.) 
Fckl. on apples; F. pyrinum , (Lib.) Fckl. on pears. Quince and pear leaf 
blight, Fntomosporium maculatum, L6v. Taphrina deformans, Glceosporium 
venetum or G. necator, Sphcerella fragarice, Sacc. and various grape diseases. 
Gives latest ideas in treatment of various maladies. 
117. Beadle, D. W. The apple scab. Horticultural Art Journal, Rochester, N. Y. 
October, 1890, Vol. V, part 10, p. 82. Sums up work of L. R. Taft in Mich., 
Agr. Exp. Sta. in 1889 ( see 104). 
118. Bessey, Ciias. E. The completion of Saccardo’s Sylloge Fungorum. American Nat¬ 
uralist, July, 1890, XXIV, 283, p. 675. Reviews and commends the work, 
giving synopsis of orders with total numbers of species described, 31,927 in all. 
119. Bolley, H. L. Potato scab, a bacterial disease. Bot. Gaz., September, 1890, Vol. 
XV, No. 9, p. 234. Abstract of paper read before A. A. A. S. Botanical Club, 
August 19, 1890. Gives histology and biology of disease, with outline of in¬ 
fection experiments performed. 
120. -. Potato scab, a bacterial disease. Agricultural Science, La Fayette, Ind., 
September 1890. Vol. IV, No. 9, pp. 243-256. Discusses at some length the 
theories regarding the nature and cause of the disease, viz., mechanical irri¬ 
tation, insect agencies, chemical erosion, excess of moisture, action of fungi. 
Follows with a record of original investigation, noting work of Dr. Brun- 
chorst, of Sweden, who describes Spongospora solani as cause of the mal¬ 
ady. Records results of various infection tests, inoculating young tubers in 
various ways with various species of bacteria found present in the diseased 
areas. Gives conclusive experiments to determine that disease is transmit¬ 
ted by the practice of planting scabby seed xiotatoes.
