536 EXPEEIMENT STATION RECORD. 



in 1910 and 2,803 lbs. per acre in 1911, the starch content ranging from 60 to 

 64 per cent. The yield of green forage ranged from 7 tons IS cwt. to 10 tons 

 13 cvrt. per acre. 



The soy bean in New Jersey, J. H. Voorhees (Neto Jersey Stas. Giro. 21, 

 pp. 3-8). — This circular gives the habits, characteristics, varieties, and uses of 

 and directions for planting, cultivating, harvesting, and thrashing the soy bean 

 under New Jersey conditions. 



The variability of the nitrogen content of sug'ar beets, K. AndrlIk and 

 J. Urban (Ztschr. Zuckerindus. Bahmcn, 36 {1912), No. 9, pp. 513-519, fig. 1).— 

 Analyses of 100 sugar beets are reported, including beets produced from a 

 mother beet of normal nitrogen content (0.18 per cent), and those from a 

 mother beet rich in nitrogen (0.3 to 0.35 per cent). 



The results showed that the nitrogen content varied in the normal class from 

 0.115 to 0.312 per cent, and in the class rich in nitrogen from 0.13 to 0.272 per 

 cent. In the offspring of a single mother beet the nitrogen content seems to 

 follow certain laws. With equal sugar content of individuals of the same class, 

 the nitrogen content varied within its limits, except in cases of minimum and 

 maximum nitrogen content. Similarly, the sugar content varied with equal 

 nitrogen content, but the extremes in the variability of the nitrogen content 

 were much greater than those of the sugar content within the same class. 

 The nitrogen content varied to 75 per cent of the average, while the sugar con- 

 tent varied to only 17.5 per cent of its average. It seemed that the sugar and 

 nitrogen content of any one class or family is not accidental but follows a cer- 

 tain law. 



The selection of sugar cane with a view to reg'enerating and improving 

 cane varieties, W. Maxwell {Bui. Agr. [Mauritius^, 3 {1912), No. 27, pp. 

 685-695; abs. in Internat. Inst. Agr. [Rome'], Bui. Bur. Agr. Intel, and Plant 

 Diseases, 3 (1912), No. 6, pp. 1309-1311).— Three methods of selection are de- 

 scribed, based upon the weight of cane, the sugar content, and the specific 

 gravity of cane tops. It is noted that as a rule the heaviest stalks are the 

 richest in sugar. 



Sweet potato culture, W. B. Kille (New Jersey Stas. Circ. 19, pp. 2-8). — 

 This circular gives the methods used in the production of this crop at Swedes-

Tobacco breeding in Connecticut, H. K. Hayes, E. M. East, and E. G. Bein- 

 HART (Connecticut State Sta. Bui. 116, pp. 5-6S, pis. 12). — This bulletin con- 

 stitutes a report of progress in studying the fundamental principles involved 

 in tobacco breeding, begun by the station in 1908 in cooperation with the Office 

 of Tobacco Investigations of the U. S'. Department of Agriculture and the 

 Laboratory of Genetics of Harvard University. 



The effects of inbreeding in a close fertilized species is discussed, and pre- 

 vious work on the effects of selection, inheritance of size characters, and tobacco 

 breeding is cited. The 4 different types of commercial tobacco — viz, Broadleaf, 

 Havana, Sumatra, and Cuban — that furnished the starting point for these 

 investigations are described. 



Reports are made on observations of 3 families — Havana X Sumatra and 

 Sumatra X Havana, S'umtra X Broadleaf, and Havana X Cuban — in regard to 

 quality of cured leaves, grain in tobacco leaves, texture, and inheritance of leaf 

 number, shape, and size. The variety Halladay Havana was produced at 

 will by crossing the Havana and Sumatra varieties. The relative values of 

 experimental selections of this cross when compared with Havana, valued at 

 100, ranged from 74.2 to 162.6. 



"The results obtained from the Broadleaf X Sumatra cross show that, as a 

 rule, each character, such as leaf size, leaf shape, number of leaves, and type
