536 EXPERIMENT STATION EECORD. 



Variety test of oats, 1906-1908, C. F. Noll {Pennsylvania Sta. Rpt. 1909, 

 pp. 106-112). — During the years 1906, 1907, and 1908, the Japan variety yielded 

 35.3, 65.3. and 56.7 bu. per acre, respectively, but in 1907 was exceeded by 

 Sixty-Day and Silver Mine with yields of 6S.7 and 65.9 bu. per acre, respectively. 

 It also stood first in average yields for the period 1905 to 1908 with 51.7 bu. 

 per acre. During an 18-year period it averaged 50.68 bu., during 13 years 52.19, 

 during 11 years 52.37, and during 10 years 52.57, but for the 10-year period was 

 exceeded by White Maine with an average of 56.31 bu. per acre. During a 

 9-year period Silver Mine stood first with 53.6 bu., during an 8-year period Czar 

 of Russia with 54.88 bu., and during a 2-year period Sixty-Day with 59.22 bu. 



The seed of a number of varieties treated with formalin showed no traces of 

 smut, but untreated seed of the Irish Victor yielded 16 per cent of smutted 

 heads, Japan 11 per cent. New Danish White 8 per cent, Long White Tartar 

 7 per cent, Czar of Russia 20 per cent. Fourth of July 16 per cent, and Big Four 

 18 per cent. 



Variety test of potatoes, 1906-1908, C. F. Noll {Pennsylvania Sta. Rpt. 

 1909, pp. 113-12.'f). — This article is largely a reprint of Bulletin 98 previously 

 noted (E. S. R.. 23, p. 139). 



Studies in Indian fiber plants. I, On two varieties of sann (Crotalaria 

 juncea), A. and G. L. C. Howard {Mem. Dept. Agr. India, Bot. Ser., 8 {1910), 

 No. 3, pp. 177-189, pis. 3). — The botanical and cultural characters of a local 

 variety of sann-hemp are compared with those of the Jubbulpore variety. 

 Yields and chemical analyses are given and the results of tests of sann as a 

 green manure for the tobacco crop are reported. References are given to the 

 literature of the subject. 



Soy beans the basis of Manchurian commerce, R. Hoagland {Minn. Farm 

 Rev., 15 {1910), No. 6, pp. 121-123, 138, 139).— This article discusses the com- 

 mercial importance of the soy bean in Manchuria, outlines its limits of growth 

 in that country, and reports chemical analyses of jNIanchurian soy beans and 

 soy-bean cake. 



Growing' sugar beet seed in South Dakota, J. H. Shepard {South Dakota 

 Sta. Bui. 121, pp. 685-698, figs. 2).— This is a continuation of Bulletin 117, pre- 

 viously noted (E. S. R., 22, p. 535) and presents the results in 1909. 



The ground occupied was subsoiled to a depth of 24 in. The minimum sugar 

 content required of beets for their retention in the experiment was lowered to 

 14 per cent for this season, as had favorable weather permitted a content of 

 18 per cent would have been reached in a few days longer. The great fluctuation 

 from the original type is disappearing. A table presents the number of mother 

 beets of each station number, the number analyzed in 1909, their average sugar 

 content, weight in grams, lowest sugar content, and highest sugar content. The 

 55 singles saved for 1909 include the very best beets grown in each variety. 



Variation and correlation in timothy, C. F. Clark {New York Cornell Sta. 

 Bui. 279, pp. 30l-<i50, pgs. 12, eltarts 9).— A brief statement is given of the man- 

 ner of conducting the experiments with a review and bibliography of similar 

 work. 



Variations from 0.25 to 0.75 in. in leaf width ; from 4 to 15 in. in length ; from 

 3 to 8 in. in number of leaves per stem ; from 1 to 12 in. in length, and from 0.2 

 to 0.4 in diameter of head; from IS days in earliness of blooming and from 

 3 to 23 days in length of blooming period are reported. The leaves varied from 

 flat to boat-shaped, the stems from erect to decumbent in direction, and both 

 stems and heads from green to reddish or bluish purple in color. Some plants 

 behave as annuals, while on some plats a large percentage of the plants are 

 still vigorous, although 6 years old. Single plants varied in stooling power from
