36 EXPERIMENT STATION RECORD. 



parative tests of large and .small seed Imlls of the sugar Iteet, c-ondiieted ))y different 

 investigators and by the author, are rei^orted. The conclusion drawn from these 

 results is that the seed balls should be of medium size, from 0.3 to 0.5 cm. in diame- 

 ter, and weighing at least 2.5 gm. per hundred. 



Breeding' sugar beets, von ROmker {Jdhrb. Deut. Landw. GeselL, 16 {1901), 

 pp. 219-231). — A review of the work of breeding and improving sugar beets by dif- 

 ferent investigators. A detailed description is given of how this line of investigation 

 is carried on. 



The growth, of the sugar beet, (). Vibkans [Bl. ZucJccrriibenbau, S {1901), Xos. 

 20, pp. .10G-ol3; 21, pj). 323-331). — The vegetative functions of the plant are dis- 

 cussed and the influences of different factors on its growth are pointed out. Obser- 

 vations in this line made by different investigators are reviewed. 



Superphosphate and nitrate of soda as fertilizer for sugar beets, F. Luhan- 

 sKi [Bl. Zuckeiriibenbuu, 8 {1901), Xo. 24, pp. 370-379). — Tabulated results of cooper- 

 ative experiments with superphosphate and nitrate of soda for sugar beets are 

 presented and briefly discussed. 



Experiments with seedling and other canes at Barbados in 1901, J. P. 

 d' Albuquerque and J. R. Bovell {Imp. Ikpt. Ayr. West Indies, Pampldel 13, 1901, 

 pp. 47): — A short account is given of the most important results of the year with 

 experiments on selecting seedling and other canes in Barbados grown under the 

 ordinary conditions existing on the estates where they were cultivated. The general 

 field characters of the different varieties under test are briefly described and the 

 results obtained with eacli variety on black and red soil are tabulated. Barbados 

 Seedling 208, White Transparent, and Barbados Seedling 147, in the order mentioned, 

 have given the best average results. Barbados Seedling 208 germinated reaciily, was 

 generally free from disease, produced a juice of great richness and purity and a good 

 yield of sugar. This variety also gave satisfactory results from plants and ratoons 

 and on black and red soils. 



Comparative culture experiments with various seed cane varieties, J. D. 

 KoBUs and J. A. van Haastert {Meded. I'r(jefit<it. Oust Jani, 3. sn\, 1901, No. 32, 

 pp. 20). — A test with thirty unnamed varieties of sugar cane was carried on to 

 determine their quality and manner of growth in different soils. The detailed 

 results are given in tables. Great differences were found to exist, some varieties 

 yielding only 50 per cent as much as others, some grew best on heavy clay, others 

 on sand, while some grew equally well on all soils. It was also noted that certain 

 varieties made the most rapid growth in the early stages, while others grew most 

 rapidly during the latter part of the vegetative period. — n. m. pieters.

 11, pp. (198-722). — Analyses of different varieties of cane are tabulated. 



Sugar-cane diseases in Gddavari and Ganjam districts, C. A. Barber, J. W. 

 Leather, and C. K. Subba Kao {DejtI. land Records <n)d Agr., Madras, Vol. II, Bui. 

 43, 1901, pp. 181-210, 2)1. 1). — This bulletin consists of a collection of papers describ- 

 ing the culture of sugar cane in the two districts. Analyses of soils from the Godti- 

 vari district are shown in a table. i 



The cultivation of the teasel, L. A. Clinton {Rural New Yorker, 60 {1901), No. 

 2703, pp. 769, 770, figs. 3). — A general discussion on teasel culture. 



EflEects of soluble and insoluble phosphate on the turnip crop, J. Milne 

 {Trans. Higldand and Agr. Soe. Scotland, 5. ser., 14 {1902), pp. 103-105). — A brief 

 report on cooperative tests of various forms of phosphate as fertilizers for turnips is 

 presented. The greatest increase in the yield was obtained from the use of super- 

 phosphate applied with lime. The precipitation of the soluble i>hosphate in super- 

 phosphate I y lime did not seem injurious to the turnip crop. 



The adaptation and improvement of winter wheat, T. L. Lyon {Nebraska-
