35. LtJHRiG. Ueber den Blausauregehalt des Phaseolus lunatus. [On the hydrocyanic 

 acid content of Phaseolus lunatus.] Pharm. Zentralhalle 62: 95-97. 1921. — Twenty ship- 

 ments of Rangoon beans were examined in which the amount of hydrocyanic acid ranged 

 from 2.3 to 37.7 mg. in 100 g. of beans. This quantity of hydrocyanic acid is not detrimental 

 to health, because practically all of it is lost by washing the beans, boiling in water and dis- 

 carding the water. — H. Engelhardt.

 1921.— Note is given on Gilia squarrosa, California stinkweed. — L. R. Waldron. 



37. Matenaers, F. F. O. P. V. Silage. Mitteil. Deutsch. Landw. Ges. 36: 184. 1921.— 

 A note on oat-pea-vetch silage said to be very satisfactory in Nova Scotia. An average of 

 12 tons per acre green matter may be secured, and this has a higher dry weight than maize. — 

 A. J. Pieters. 



38. Matenaers, F. F. Praktische Erfahrungen rnit der Sonnenblumensilage. [Practical 

 experience with sunflower silage.] Mitteil. Deutsch. Landw. Ges. 36: 154. 1921.^ — A brief 

 account of success with this silage in Iowa is copied from the St. Paul, Minnesota, "Deutschen 

 Farmer." The sunflowers yielded 20 tons per acre against 10 tons of maize on similar land. 

 In spite of some decay due to imperfect ensiling, cattle ate the silage as eagerly as the maize 

 eilage; there was no apparent difference in the flow of milk. — A. J. Pieters. 



39. MoFFET, S. Conseils practiques pour ameliorer la culture de la pomme de terre. 

 [Practical advice to improve the cultivation of potatoes.] Bull. Sci. Pharm. 27: 638-G42. 1920. — 

 Diseases of the potato are discussed and advice is given in regard to the selection of the tubers 

 for propagation. — H. Engelhardt. 



40. Moore, J. C. Report on the Agricultural Department, Grenada. Imp. Dept. Agric. 

 West Indies Rept. Agric. Dept. Grenada 1918-19: 38 p. 1920. — Work of botanical interest 

 falls under 4 heads: (1) Work in gardens and observations on plants, including a note on a 

 guava (Indian White) yielding a fruit weighing 10 oz. and having a circumference of 10 in.; 

 (2) plot and other experiments, with remarks on yam culture, corn storage, edible beans, 

 and Sunn Hemp {Crotalaria juncea); (3) progress of industries, giving export figures, etc., 

 of cacao, spices, cotton, and limes; (4) plant legislation. — J. S. Dash. 



41. Moore, J. C. Report on the Agricultural Department, Grenada. April-December 

 1919. Imp. Dept. Agric. West Indies Rept. Agric. Dept. Grenada 1919: 21 p. 1921.— Plot 

 experiments with Sunn Hemp {Crotalaria juncea) and with yam varieties {Momordica 

 cochinchinensis) are recorded. The latter grew better from unshelled than from shelled seed. 

 Onions can be successfully and profitably grown under Grenada conditions; experiments gave 

 a yield of 3.38 tons of dried onions per acre. Full account is given of the status of the cacao, 

 spice, sugar, cotton, coconut, and lime industries. — /. S. Dash. 



42. Neidig, Ray E., Robert S. Snyder, and C. W. Hickman. Sunflower silage diges- 

 tion experiment with cattle and sheep. Jour. Agric. Res. 20: 881-888. 1921. — Feeding experi- 

 ments and analyses of sunflower (Helianthus) silage indicate that it compares very favorably 

 with maize silage. Where both maize and sunflowers can be grown, the selection of a silage 

 crop depends upon comparative tonnage per acre and cost of production. — D. Reddick.

 Zeitschr. Untersuch. Nahrungs- u. Genussmittel 40: 243-246. 1920. 



44. Pitt, J. M. Farmers' experiment plots. Maize experiments, 1919-20. Central coast 

 district. Agric. Gaz. New South Wales 32: 25-27. 1921. — Maize trials were conducted in 

 cooperation with a number of farmers. With a favorable season, high yields were secured.
