640 EXPERIMENT STATION RECORD. [Vol.41 



The length of the grain was dependent upon two factor pairs, Aa, which must 

 be present in order that long grains may appear, and Vv, which has a shorten- 

 ing effect. The influence of the latter factor is said to be less marked than that 

 of the former. The correlation between Aa and LI is represented by the ratio 

 of 5 AL : 1 Al : 1 aL : 5 al. 



The hooded form was determined by a factor pair Kk. The hooded cultures 

 examined are said to have contained the factor A in a latent condition, this 

 being capable of expressing itself only in the presence of k. In the heterozy- 

 gotic condition of KkAA or KkAa so called stemmed hoods appeared. 



Three factors were found to be involved in the toothing of the nerve of the 

 flowering glume. The first factor pair, Gg, which produced marked toothing, 

 was found to be correlated with Zz according to the ratio of 1 ZG : 5 Zg : 5 zG : 

 1 zg. The second factor G'g' gave rise to isolated teeth, and transmitted itself 

 Independently of the first factor according to the simple ratio of 3 scarcely 

 toothed individuals : 1 not toothed. The third factor effected quite fine toothing, 

 perceptible only under the microscope.

 book 1918, pp. 123-136, pis. 4). — The author traces the early history of corn cul- 

 ture in America, and briefly discusses the importance of the crop both in the

"Northerns" cotton, G. R. Hilson {Agr. Jour. India, IJ^ {1919), No. 2, pp. 

 SOO-314). — The production and marketing of so-called Northerns cotton in the 

 Madras Presidency is described. Improvements in the crop, in cultural methods, 

 and in marketing conditions are suggested. Northerns is said to comprise a 

 mixture of varieties of Gos.<ii/piinn lierhaceum and O. indicum. 



The improvement of " Tinnevellies " cotton, R. Thomas {Agr. Jour. India, 

 14 {1919), No. 2, pp. 315-330). — Suggestions are presented for the improvement 

 of the crop and of marketing conditions in the Tlnuevelly tract situated in the 

 southern part of the Madras Presidency. It is stated that the so-called Tinne- 

 vellies cotton is grown on an area of about 600,000 acres, and comprises two 

 distinct varieties known locally as karunganni {Oossypium obtusi folium) and 

 uppam (O. Jierbaceum) .

 J. M. Workman {U. S. Dept. Agr. Yearbook 1918, pp. 399-408, figs. 2).— The 

 authors discuss the necessity for better constructed and better managed cotton 

 warehou.ses, the functions of the warehouse, the formation of cooperative or- 

 ganizations among farmers for the construction and operation of cotton ware- 

 houses, and the location of the warehouse. 



Crotalaria usaramoensis as a fiber plant, G. F. J. Bley {Dept. Landb., Nijv. 

 en Handel [Dutch East Indies], Medcd. CuUuurtuin, No. 12 (1918), pp. 1-lS, 

 pis. 6). — The production and utilization of V. usarauiansis for fiber in Java
