334 EXPERIMENT STATION RECORD. 



Some plants when harvested show a wide ratio, while others, especially those low 

 in sugar content, show a narrow one. 



The sugar-building capacity of the leaves reaches its maximum about the 

 middle of July, but this period is somewhat dependent on the time the seed 

 germinates. When the leaves are removed about July 1 tlie consequent new 

 growth will show a greater sugar-elaborating capacity than the older leaves. 

 When the sugar formation is at its maximum, 100 gm. of dry matter in the 

 foliage elaborates from 4.3 to 4.8 gm. of sugar per day. 



The average quantity of sugar formed showed little variation during any 

 particular season among the beets grown from different kinds of seed, but the va- 

 rious seasons showed considerable differences in this regard due to the dif- 

 ferences in the conditions of growth. In I'JOG, it was observed that 100 kg. of 

 dry matter in the leaves produced from 2.5 to 2.6 gm. of sugar per day, while 

 in 1907 the daily production reached 3 gm. 



Notes on classification and examination of the canes at present indigenous 

 to Bengal, C. S. Taylob {Dept. Agr. Bengal, Dept. Rec, 1910, No. 3, pp. 21, 

 fig^ i). — The author describes a number of cane varieties and outlines the chem- 

 ical work undertaken on them. He presents in tabular form data on the com- 

 parative juice extraction of the varieties and the results obtained in the esti- 

 mation of the fiber and saccharose in their megass. 



Cane sugar, N. Deerr {Manchester, England, 1911, pp. XV +592, pis. 23, 

 figs. 239). — This is "a text-book on the agriculture of the sugar cane, the man- 

 ufacture of cane sugar, and the analysis of sugar-house pi'oducts, together with 

 a chapter on the fermentation of molasses." About 170 pages are devoted to 

 the agriculture involved, but the major portion of the work is devoted to the 

 technical and manufacturing aspects of the subject. Reference lists follow the 

 several chapters, while the preface contains book lists on the agricultural, man- 

 ufacturing, chemical, analytical, and other phases of the subject, and a list of 

 journals devoted to the sugar industry. 



Thickness of sowing summer wheat, depth, and time of plowing under it, 

 A. Aleksandrovich [Khutoryanin, 1909, No. 50; abs. in Zhur. Opytn. Agron. 

 {Russ. Jour. Expt. Landw.), 11 {1910), No. Jf, pp. 595, 596). — The author reports 

 results obtained at the Buguruslan experiment field in the Samara government. 

 Four years' data show that plowing 7 and lOJ in. deep in August resulted in 

 yields of 85 and 89 poods per dessyatina (1,135.60 and 1,189.04 lbs. per acre) 

 of grain, respectively. September plowing to the same depths was followed by 

 yields of 81 and 88 poods per dessyatina, respectively. Sowings of 4, 5, and 6 

 poods per dessyatina were followed by yields of 89, 106, and 111 poods per 

 dessyatina, respectively. 



The influence of nitrate of soda applied at different times on. the struc- 

 ture of the endosperm and on the protein content of wheat, F. Moertlbauek 

 {Illus. Landw. Ztg., 30 {1910), No. 98, pp. 903, 90//).— The results of experi- 

 ments showed that very early top-dressings of nitrate of soda on winter wheat 

 decreased the flintiness of the kernel, while late applications increased this 

 property. In every case where part of the quantity was applied late the hard- 

 ness of the grain was improved. A top-dressing given when the heads began 

 to form invariably produced a marked increase in the degree of flintiness. 

 Experiments with spring wheat gave very similar results. The dry matter 

 content of the grain was only slightly increased as a result of early applications 

 of the nitrate. The protein content in general varied with the flintiness of the 

 grain of both winter and spring v/heat; the correlation, however, not being so 

 definite that the degree of flintiness could serve as a reliable index to the 

 protein conteiit. The results seemed to indicate further that flintiness is not 

 necessarily the only condition which determines the protein content.
