asphyxiation and rapid decay. It is also stated that normal rice fields have 

 been plowed successfully by machinery. 



Investigations on the influence of injury and the loss of leaves of rye on 

 the development of the spikes and kernels, O. Schlumbergeb (Arh. K. Biol. 

 Anst. Land u. Forstw., 8 (1913), No. 5, pp. 515-551, figs. 14). — Leaves of rye 

 plants vrere removed by scissors and others slit into approximately 3 parts with 

 a needle at 2 periods of growth, at the commencement of the shooting stage and 

 at the beginning of the flowering stage. The effects of these treatments on the 

 quality (size) and quantity (weight) were observed. 



Either treatment had little influence on the kernel or head when given before 

 the shooting stage, but when given just before the flowering stage the injury 

 was considerable. The injury by removing all of the green leaves at the 

 second period was scarcely more than by the removal of only the 2 youngest 

 leaves. Slitting the leaves caused injury, but in much less degree than did 

 removal. In general the injury was much greater to the kernels at the extreme 

 ends of the heads than to those located within the middle third. The quanti- 

 tative injury to the kernels was relatively greater than the qualitative injury 

 in all cases. Chemical analysis showed practically no difference in the kernels 

 from the different treatments. 



The influence of the previous crop on the yield of rye, J. von Lents (Illus. 

 Landw. Ztg., 32 {1912), tfo. 78, p. 725, fig. i).— Grain yields were produced of 

 1,822 kg. per hectare (1,621 lbs. per acre) following summer fallow. When 

 lupines were plowed under in the flower, pod, and seed stages, the succeeding rye 

 crops were 2,942, 2,503, and 1,844 kg., respectively. With barley as a previous 

 crop the yield was 1,142 kg. 



The varieties of soy beans found in Bengal, Bihar, and Orissa, and their 

 commercial possibilities, E. J. Woodhouse and C. S. Taylor {Mem. Dept. 

 Agr. Indi<L, Bot. Ser., 5 {1913), No. 3, pp. 103-176, pis. 5).— The authors discuss 

 the varietal characteristics, types, distribution, cultivation, yield, value, and 

 uses of some soy beans found in cultivation in Bengal. Chemical analyses show 

 the nitrogen content to range from 4.73 to 7.67 per cent, according to type. The 

 highest oil content reported was 16.28 per cent. 



Cambodia soy beans {Agr. Prat. Pays CJiauds, 12 {1912), No. 116, p. Jfll; 

 Internat. Inst. Agr. [Rome}, Mo. Bui. Agr. Intel, and Plant Diseases, 4 {1913), 

 No. 2, p. 210). — It is noted that soy beans have been successfully grown in 

 Cambodia, Indo-China, containing 41.6 per cent of protein and 18.6 per cent 

 of fat. 



Soy beans— Why not? A. Bunn {Country Gent., 78 {1913), No. 31, pp. 1138, 

 1139, fig. 1). — This article gives the results of some tests in Pennsylvania of 

 soy bean varieties in regard to frost resistance. 



Haberlandt (yellow) and Wilson (black) lost only 5 per cent of seed by 

 remaining in the field during the winter, while other varieties lost as high as 

 60 per cent. " Volunteer seedings in 1912 and 1913 were in excellent condition, 

 without exception, at oats plowing, which is about the middle of April." 



Frost-resisting soy beans, A. Bunn {Country Cent., 78 {1913), No. 44, p. 

 1614, fiQ- !)• — III this article the author relates his experience with Sable, 

 Haberlandt, and Peking, 3 varieties of soy beans that resumed growth and 

 made good yields after being cut down by a late frost. It is noted that when 

 soy beans were planted with a grain drill as large yields of hay and grain were 

 obtained, and with much less expense, as when planted in rows and cultivated. 



The influence of phosphoric acid on the growth and development of sugar 

 beets, H. Wilfabth, H. Roemeb, and G. Wimmee {Ztschr. Yer. Deut. ZucTcer-
