increase throughout November and December, even though the lower leaves 

 for a distance at 5 or 6 cm. (about 2 in.) on the stem had been removed, but 

 that the average weight of the roots was less in cases when the leaves had been 

 removed. The author concludes, therefore, that the sugar formation takes 

 place regardless of the presence or absence of the leaves, and that this action 

 must take place within the root. 



Spacing experiment in sugar-beet cultivation in Hungary, 1912, B. von 

 Jancs6 {Osterr. JJngar. Ztschr. Zuckerindus. u. Landw., 43 {1914), No. 1, pp. 

 7-16). — In row spacing varying from 14 to IS in. and plant spacing varying 

 from 8 to 10 in. the yield results from 19 fields showed a spacing of 10 by 14 

 in. to be most satisfactory. 



Catalogue of the German division of the library of L. S. Ware on the 

 sugar industry {Katalog der Deutschen Abteilung einer Special-Bibliothck des 

 Hcrrn L. S. Ware ilher die Zuclcerindustrie. Courhevoie, France, [W-f], pp. 

 S3).— A bibliography of nearly 550 volumes, comprising the works on the sugar 

 industry in the German language found in the private library of the late L. S. 

 Ware (E. S. R., 29, p. 719). 



Cataloguei of the works on sugar and the sugar industry (Katalog der 

 Werke iiher Zuckcr und Zuckerindustrie. Locarno, Switzerland, 1914, PP- 

 10). — This is an appendix of the above and includes over 400 volumes on sugar 

 and the sugar industry in German. 11 in Danish, 50 in Spanish, 315 in Dutch, 13 

 in Hungarian, 58 in Italian, 9 in Bohemian, 6 in Latin, 11 in Polish, and 1 each

The " Stewart Cuban " variety of tobacco, II. K. Hayes ( Connecticut State 

 Sta. Rpt. 1913, pt. 6, pp. 385-890, pis. 2).— This article describes a new type 

 of Cuban tobacco (E. S. R., 31, p. 43) which differed from the normal Cuban 

 in having leaves of a somewhat lighter green shade and in being nearly free 

 from basal suckers, the range of leaf counts being from 62 to 80. " This 

 type bred true in 1913, and when compared with the normal Hazlewood Cuban 

 gave an increase in packed yield of about 90 per cent. The quality of the cured 

 leaves was also very satisfactory." 



On the nitrogen content of the wheat kernel from trans-Volga districts, 

 N. TuLAiKOV {Zhur. Opytn. Agron. (Russ. Jour. Expt. Landw.), 15 {1914), No. 

 1, pp. 1-11; Bczcnclmk. Selsk. Khoz. Opytn. Stantsiia, No. 48 {1914), PP- H)- — 

 Results of analyses show that there was little change in the nitrogen content 

 of wheat varieties at the Bezenchuk station during 4 years of investigations. 

 Difference in the nitrogen content of the wheat kernel is ascribed to the com- 

 position and osmotic pressure of the soil solutions under given climatic con- 

 ditions, botanical variations in varieties playing no part. 



Yams (Dioscorea), R. de Noteb {Agr. Prat. Pays Chauds, 13 {1913), Nos.118, 

 pp. 1-18, figs. 9; 119, pp. 146-I6O, figs. 6; 120, pp. 215-236, figs. 2).— This article 

 gives data on the origin, history, principal species, 23 cultivated varieties, 

 and methods of cultivation of yams in Asia, Oceanica, North and South America, 

 Africa, and Europe, with analyses and culinary preparations. 



HORTICULTURE. 



[Report of the] department of horticulture, W. L. Howard and J. C. Whit- 

 ten {Missouri Sta. Bui. 117 {1914), PP- 4^7-430). — A progress report on horti- 

 cultural investigations for the year ended June 30, 1913. 



Three crops of apples have thus far been harvested from trees part of which 

 were grown from scions selected from high-producing parents and part from 

 trees of low-producing parents. There was practically as much variation in 

 yield, size, and color of fruit between trees from the same parent as there was
