 Samen. [Concerning the vitality of certain agriculturally important seeds. ] Illustrierte Landw. 

 Zeitg. 39: 282-283. 1919. — As the result of germination experiments it was found that the 

 seeds of wheat, rye, barley and oats possess greater vitality than is generally supposed. 

 Seeds of wheat 8 years old were 80 per cent viable and those of 14 years old 10 per cent viable. 

 Nearly 100 per cent of wheat seeds from 1 to 7 years old germinated. Similar results were 

 obtained with seeds of rye, barley and oats. — John W. Roberts. 



1133. Earle, F. S. Varieties of sugar cane in Porto Rico. Jour. Dept. Agric. and Labor, 

 Porto Rico 3: 15-55. 1919. — One of the principal objects of this paper is to show that sugar 

 cane varieties may be described, classified, keyed out and determined by ordinary methods of 

 descriptive botany or taxonomy. Heretofore, remarkably few descriptions of the cane 

 varieties have been published that would enable one to identify a variety. The cultural 

 value and characteristics of the numerous varieties grown in Porto Rico are described in detail. 

 A key for identification and a taxonomic description of a number of varieties is also contained 

 in the article. — Anthony Berg. 



1134. Evans, L. A. Annual report of the acting-director of agriculture. Tasmania Agric. 

 and Stock Dept. Rept. 1918-19: 1-6. 1919. — -Report giving statistics on production of prin- 

 cipal crops. District reports are included. — D. Reddick. 



1135. Fawcett, G. L. The identity of canes grown in Argentina. Internat. Sugar Jour. 

 22 : 135-136. 1920. — -The botanist of the Agricultural Experiment Station at Tucuman states 

 that Java 36 is the true P. O. J. 36 as it is grown in Java today. The probable source of this 

 incorrect designation is the description by Noel Deerr in his "Cane Sugar." Another inac- 

 curacy is calling the variety J 228 (P. O. J. 228) by two names — its own and J 139, when in 

 reality Java 228 is meant. Correspondence with the Java station and shipments of cane show 

 that the Argentina canes of Javanese origin are identical with the varieties of corresponding 

 names as grown in Java. — E. Koch.

 Boden und Klima . [The soil and climate requirements of lupine species grown for yield of seed. ] 

 Illustrierte Landw. Zeitg. 39: 199-200. 1919. — The soil and climate requirements of the 

 following species are discussed: Lwpinus luteus, L. angustifolius , L. dibits, L. cruikshanksii, 

 L. mutabilis, L. hirsuhis. — John W. Roberts. 



1138. Fruwirth, C. Zur Frage des Verpflanzens der Luzerne. [Concerning the question 

 of transplanting alfalfa.] Illustrierte Landw. Zeitg. 39:226. 1919. — Results obtained through 

 three years of experimentation indicate that greater yields of forage and seed may be expected 

 from a field in which the seed has been drilled in than from one in which a stand has been 

 obtained by transplantation. The advantages and disadvantages of both methods are dis- 

 cussed. — John W. Roberts.

 Agric. [Mexico] 5 : 26-34. 5 fig. 1919. — Explains the value of a green manure crop, the manner 

 of fixation of nitrogen by legumes and outlines the culture of cowpeas, a green manure crop 

 well adapted to Mexican conditions. — John A. Stevenson. 



1140. Gammie, G. A. Report of the imperial cotton specialist. Sci. Rept. Agric. Res. 

 Inst. Pusa 1918-19: 115-124. 1919. — The report summarizes the qualities of some of the var- 

 ious varieties of cotton grown in India, and outlines experiments either in progress or contem- 

 plated to improve the cotton yield.— W infield Dudgeon.
