Studies on the anatomy of alfalfa, O. T. Wilson (Kans. Unw. Sel. Bui., 

 7 {WIS), No. 17, pp. 291-299, pis. 5). — Cross sections of roots, stems, and leaves, 

 and the cellular structure of many parts of the alfalfa plant are described and 

 illustrated. 



Growing alfalfa in Iowa, H. D. Hughes (Iowa 8ta. Oirc. S {1912), pp. 2-11, 

 figs. 5). — Cultural notes on alfalfa growing for Iowa conditions. 



On the influence of potash and phosphoric acid on the quality of brew 

 barley, L. ScHiJL {Landw. Jahrh., ^5 {1913), No. 5, pp. 641-712). — Results from 

 field experiments in which potash and phosphoric acid were used singly and 

 combined with nitrogenous fertilizer showed that potash and nitrogen were 

 better appropriated by barley in the presence of phosphoric acid. Potash- 

 phosphatic fertilizers accompanied increased total yields and improved quality. 

 The use of 40 per cent potash salt and of superphosphate as a top-dressing 

 worked favorably. The protein content decreased under the influence of potash 

 find phosphoric acid applications and yield increase. Dry matter increased 

 with considerable regularity with the application of potash and phosphoric 

 acid, regardless of the yield. In general an improvement in 1,000-kernel weight, 

 in size, in percentage of hull, in germination ability, and in germination force 

 was noted as attributiA'e to potash and phosphoric acid. The potash and phos- 

 phoric acid-fertilized barley kernels were of a canary yellow. 



Investigations on spacing for breeding plants of brew barley, E. Claus 

 (KiUm Arch., 3 {1913), pt. 1, pp. 169-197, figs. 8).— From data collected in 1911 

 from several exi^erimeuts the author concludes that spacing is correlated with 

 stooling, with individual plant weights, and with grain weight per plant. The 

 optimum distance for brew barley in the climate and soil of Halle Station is 5 

 by 20 cm. (about 2 by 8 in.). The percentage of grain is independent of dis- 

 tance. With brew barley diy matter and extract content are in inverse ratio to 

 distance, while protein content is in direct ratio to distance. In single plants 

 the protein content increased with the stooling, with weight of head, and with 

 kernel weight, and declined when the percentage of grain and stand increased. 

 No correlation between protein content and kernel weight could be detected. 



Observations on Beta maritima from 1910—1912, O. Munerati, G. Mezza- 

 DROLi. and T. V. Zapparoli {Staz. Spcr. Agr. Ital., ^6 {1913), No. 6, pp. 415-445, 

 figs. 7 ; abs. in Osterr. Vngar. Ztschr. Zuckerindns. u. Landw., >J2 {1913), No. 6, 

 pp. 1015-1023, figs. 4)- — The authors give results of planting seeds of wild 

 beets collected on the Adriatic coast and on the banks of the river Po in 1910. 



It is concluded that although most of the individuals produce seed the first 

 year, many do not until the second year, and that these may continue to pro- 

 duce seed annually up to 6 or 7 years. Whether in a wild state or under culti- 

 vation they show a great tendency toward wide variations. Some characteris- 

 tics were rigidly transmitted while others were not. It is noted that the bien- 

 nial character of some individuals was transmitted regularly 100 per cent, while 

 others of this character produced only annuals. 



The results of 2-year selections from the wild form gave beets that weighed 

 3 kg. and contained 15 per cent of sugar, with a juice of 81 per cent purity and 

 little fiber. Five years of cultivation, it is noted, brought the wild toward the 

 sugar-beet form but not toward the stock-beet form. 



On breeding and inheritance questions in red clover, P. Holdefleiss (Kiihn 

 Arch., 3 {1913), pt. 1, pp. 81-115, figs. 5).— From a 2-year study of color char- 

 acteristics in red clover the author concluded that in general there was a cor- 

 relation between yellow seeds and light colored or white flowers, the pure-bred 

 white flowering plants always bearing yellow seeds. Dark red flower color and
