60 EXPERIMENT STATION RECORD. 



The black rot in Aveyron in 1897, E. Makre (Prog. Agr. et fit.. ?'J (1898) No. 

 17,pp.5Sl-5S5). 



On the treatment of black rot, <i. Hkhon (Prog. Agr. et Fit., 29 (1898), No. 17, 

 pp. 528-581). 



On the use of corrosive sublimate for the prevention of grape disease, 

 A. CHEVAIXIER (Prog, Ayr. et fit., 29 (189S), No. 14, pp. 420, 421). 



On the treatment of pourriture grise, L. Dkgkully (Prog. Agr. et lit.. 29 ( 1.898), 

 No. 16, p. 483). — A powder, consisting of steatite 92 per cent, .sulphate of alumina 3 per 

 cent, sulphate of lime 4 per cent, and sulphate of iron 1 per cent is descrihed. 



Concerning a corrosive sublimate fungicide, L. Degrully (Prog. Agr. et lit., 

 29 (1S9S), No. 16, pp. 4Sl-4S3).—k fungicide, consisting practically of 100 liters of 

 water, 20 kg. salt, and 5 kg. corrosive sublimate, was sold in France during the 

 past year at an extravagant price. Allowing for the market price of the salt and 

 mercury, it is said that the water sold at 1.17 francs per liter. The extravagant 

 claims for the fungicide are not substantiated, although it has considerable merit. 

 It was sold under the name ''Liqueur antiseptique agricole." 



Preparation and application of fungicides, W. C. Sturgis (Connecticut State Sta. 

 Bui. 125, pp. 16, jigs. 10). -Directions are given for the preparation and application 

 of the following fungicides: Copper-sulphate solution, Bordeaux mixture, Bordeaux 

 mixture and Paris green, ammoniacal solution of copper carbonate, potassium sul- 

 phid, corrosive sublimate, and formalin. Various kinds of spraying apparatus are 

 figured and described, the cost of the materials is given, and brief notes on when to 

 spray. 



ENTOMOLOGY. 



Proceedings of the ninth annual meeting of the Association of 

 Economic Entomologists ( TJ. 8. Dept. Agr., Division of Entomology 

 Bui, No. 9, n. ser., pp. 87). — The proceedings of the convention held at 

 Detroit, August 12 and 13, 1897. 



The present and future of applied entomology in America, F. M. Webster 

 (pp. 5-15). — The presidential address, consisting of general remarks 

 on the value of the meetings of the association, the work and position 

 of the entomologist, and his relations to politics, etc. 



Additional observations on the parasites of Orgyia leucostigma, L. 0. 

 Howard (pp. 15-18). — These observations are in addition to those 

 previously published by the author (B. S. R., 9, p. 258). From 5,000 

 larvae and pupse of Orgyia leucostigma, collected in July, 1897, there 

 issued the following species of parasites: Tachina mella, 220; Front ina 

 frenchii, 355; Euphorocera elaripennis, 464; Exorista sp., 13; Helieobia 

 helicis, 4; Phorocera sp., 45; Chaleis ovata, 551; Apanteles parorgyice, 3; 

 Dibrachys boucheanus, 10; total, 1,065. From the cocoons, 321 male 

 moths and 764 female moths were obtained. One hundred and forty- 

 six of the caterpillars or chrysalids died from a disease that the author 

 calls black rot and 33 from another disease that he calls red rot. In 

 percentages the results were as follows: Moths, 21.07; dipterous para- 

 sites, 22.02; hymenopterous parasites, 11.02; disease, 3.58; total, 57.69. 

 This leaves about 2,000 chrysalids that died from some unknown cause. 

 The mortality ratio was 79 as contrasted with 98.2 per cent at a corre- 

 sponding time in 1896.
