glands aud some with few; some plants liad bolls deeply pitted and some had 

 bolls with smooth surfaces, the oil glands being more deeply buried in the 

 tissues of the wall. 



" The seed aud lint characters were as diverse as the boll characters. The 

 seeds from the different plants were of many sizes and shapes and no two 

 plants showed the same distribution of fuzz on the seed. The seed of one 

 hybrid plant was entirely naked while usually there were tufts of fuzz at either 

 the apex or base of tJie seed or at both ends, these tufts varying in size for the 

 different plants. Several plants had the seeds completely covered with thick 

 fuzz, but even these differed from each other in that some had green fuzz, 

 some brown, and some pure w'hite. The lint also varied greatly In both 

 quantity and quality and ranged in color from a pure white to a decided bufif. 

 From a commercial standpoint the lint would have been' of little value because 

 of the variation in length and quality of the lint from the different plants." 



Twelve individuals derived from self-fertilized seeds from the same conjugate 

 Hindi X Egyptian plant are described in- detail and serve to show those features 

 in which the plants differ most noticeably from each other and from the 

 parental types. 



Relation of density of stand and yield in cotton, A. Sheedeb (Isv. Turkest. 

 Selsk. Khoz. Opyin. StantsU, 4 {1913); ahs. in Zhur. Opytn. Agron. {Russ. 

 Jour. Expt. Landw.), U, {1913), No. 5, pp. 522, 523).— Observations of the 

 author indicate a ratio existing between the soil surface occupied by the cotton 

 plant aud the leaf surface of that plant. This ratio is unaffected by the thick- 

 ness of planting, aud the soil condition seems to be the chief factor in determin- 

 ing it. The number of bolls on each plant was found to be approximately pro- 

 portional to the distance between each plant, and it is noted that the number of 

 maturing bolls was found to depend on the number of stems per unit area and 

 not on the total number of ovaries. 



Close planting- of cotton to avoid frost injuries, R. Shredeb {Turkest. 

 Sclsk. Khoz., No. 2 {1913); ahs. in Zhur. Opytn. Agron. {Russ. Jour. Expt. 

 Landw.), IJf. {1913), No. 5, pp. 51S, 519). — This notes the success of close 

 planting as a means of securing early maturity of the bolls to avoid injuries by 

 early frosts. 



Flax culture, V. E. Freeman {New York: Author, 1915, pp. 19, figs. 9). — 

 This book treats of the preparation and industrial use of the flax plant in its 

 various phases. 



Germination of hemp seed, G. Consolani {Staz. Sper. Agr. ItaL, Jil {191 J/), 

 No. 6, pp. Jf27-430, figs. 2). — This article gives results of germination tests in 

 1914 of hemp seeds grown in the years 1909-1913. The percentages of germina- 

 tion were 60, 0, 71, 65, and 79, respectively. With the 1909 seeds the plumules 

 did not appear until the ninth day and germination continued until tlie twenty- 

 first day, while with the 1913 seeds the plumules appeared on the sixth day and 

 germination was ended by the sixteenth day. 



Experiments on lime requirements of lupines, voN Seeliiorst, Geilmann, 

 and R. Thiele {Deut. Landw. Presse, 42 {1915), No. 1, pp. 3, 4, figs. S).— This 

 article reviews previous work of investigators, and gives results of pot experi- 

 ments conducted at GiJttingen to determine the influence of applications of lime 

 on the nodule development and consequent growth of the plants. Half of the 

 pots were filled with sterilized soil, and these soils were then inoculated by 

 means of soil known to contain the proper nodule-forming bacteria and that 

 had been variously treated with lime, sodium nitrate, and ammonium sulphate. 



Tabulated data show that the maximum development of nodules was produced 

 with the untreated inoculating soil or that containing small quantities of lime 

 or nitrate of soda. The combined applications of small or large quantities of
