conditions found at Gooding, variety tests, and some results of experiments on 

 time to irrigate. Better success was obtained by commencing the irrigation 

 about the time the tubers began to form, malving about four irrigations and 

 applying about IJ cu. ft. per acre in deep furrows, than in commencing when 

 the plants are 4 or 5 in. high or when the tubers are the size of an egg. 



Ury land potato culture for southern Idaho, L. C. Aicher (pp. 28-39). — This 

 article surveys the dry land potato industry in southern Idaho and gives notes 

 on cultivation and harvest methods. 



Diseases and insect pests of the potato, C. E. Temple (pp. 40-67). — ^This paper

Potatoes, L. Greene and T. J. Maney {loica 8ta. Circ. 13 {1913), pp. 2). — 

 This circular describes 5 early and 6 late varieties of potatoes that have been 

 found to compare favorably with Early Ohio and Rural New Yorker in Iowa. 

 Planting, seed treatment, and spraying directions are given. 



Beport on the progress and recent work in sugar beet culttire, M. Hoff- 

 mann (Bl. Zuckcrriibenhau, 20 (WIS), No. 1, pp. 1-7). — This article reviews 

 and summarizes the results of recent work of investigators on nitrogen content 

 of sugar beets, cultural methods, excrescent growths, weight and sugar content 

 of roots, influence of water, quality and quantity of yield, composition of large 

 beets, defoliation, nematodes, influence of light on the seed production, changes 

 of the beet during storage, germination of dried seed.s. and Mendelian studies. 



Progress and developments in the culture and selection of the sugar beet 

 and sugar-beet seed {Sucr. Indig. et Colon., 82 (1913), Nos. 23 pp. 534-539; 

 2J,, pp. 561-564; 25, pp. 580-584; 26, pp. 605-607; 83 (19'14), Nos. 1, pp. 7-11; 

 2, pp. 32-36; 3, pp. 58-61). — This reviews and summarizes the recent literature 

 relating to the cultivation, anatomy, physiology, composition, fertilization, seed 

 selection, by-products, tools and machines, uses of sugar, by-products as feed, 

 insect enemies, and diseases of sugar beets. 



On the physiology of beet seeds, H. Plahn-Appiani {Bl. Zuckerriibenbau, 

 21 {1914), No. 1, pp. 1-5). — This article reports an experiment to te.st the value 

 of the size factor in beet seeds and in beet seed balls. The following table 

 shows the results obtained from a single plant, both with seed balls allowed 

 to mature naturally and those in which one-half of the plant had been pruned 

 back to allow the seed balls on that side to grow to a larger size.
