[Chilled V. unchilled potato seed for fall planting], L. Foot {Univ. Ark. 

 Col. Agr., Ext. Circ. 38 (1917), pp. 4, fig. i).— The results of a field test with 

 chilled and unchilled seed potatoes from the spring planting used for the fall 

 crop immediately following showed an estimated acre yield for the chilled 

 seed of 17.88 bu. as compared with 0.G2 bu. per acre from the unchilled seed.

 Talmage; Definitions of Market Types for Seven Leading Varieties of Pota- 

 toes, by C. L. Fitch ; Modern Methods of Potato Culture Abroad and in this 

 Country, by L. D. Sweet ; Origin, Introduction, and Primitive Culture of the

Comparative trials with rye grasses, E. Breakwell {Agr. Gaz. N. 8. Wales, 

 28 {1917), No. 5, pp. 317, 318). — Comparative trials with Italian and Western- 

 wolth rye grass at Glen Innes, Yanco, and Grafton Experiment Farms and 

 Hawkesbury Agricultural College are briefly noted. Westernwolth rye grass 

 is considered much superior to Italian rye grass, consistently producing a 

 heavier and more uniform crop, and being especially well adapted to the coast 

 and irrigated areas of New South Wales. Both grasses behave as annuals in 

 this region. 



Weight of seeds as related to their number and position in the pod, B. D. 

 Halsted {Torreya, 17 {1917), No. 6, pp. 101, 102).— The following data are 

 presented to show the relation of the weight of soy-bean seeds to the number 

 and position of the seeds in the pod for three varieties varying greatly in 

 season of growth and size of seed. A total of 29,100 seeds was examined.
