bauanas was found to contain four organisms, a saocharoniyces designaled 

 K. musw, a bacterial form not identified, a variety of Oospora lactis, and a va- 

 riety of Mycoderma. Fermentation of Ijauaua must by means of S. musw is 

 said to yield, if sugar is added to the mnst. a slightly alcoholic liquor of good 

 color and attractive organoleptic properties. 



METEOROLOGY. 



Temperature influence on planting and harvest dates, J. B. Kincer {U. S. 

 AIo. Weather Rer., J,7 (1919). Xo. 5, />p. S12-323, figs. 20).— The author discusses 

 certain significant temperature values which seem to establish the average 

 spring planting dates of wheat, oats, early potatoes, corn, and cotvon, together 

 with the heat necessary to bring them to maturity after planting known as the 

 " thermal constant " or " the accumulated day-degrees of temperature above the 

 mean temperature at which planting is accomplished." 



As thus computed, very little difference was found in the amount of heat 

 necessary to mature most staple spring-planted crops when the average variety 

 of corn was considered. It is suggested that the mean temperature at which 

 the planting of a given crop takes place be employed as a base for any method 

 of temperature summation rather than a general base for all crops. It is 

 stated that the normal daily temperatures accompanying the beginning of the 

 seeding of tlhe principal spring-grown crops are from 37 to 40'' F. for wheat, 43" 

 for oats, 45° for early potatoes, .55° for com, and 02° for cotton. The successful 

 commercial production of cotton and corn is said to be limited by available 

 thermal constants of approximately 2,000° and 1,000°, respet.'tively.
