has shown the smallest degree of winter resistance of the varieties under test. 

 did not in all of the eight tests have a sugar content lower than that Of Small

 sidered adequate to warrant tlielr application In wheat breeding work. 



A dwarf wheat, G. II. CUTLBB (Jour. Amcr. Soc. Agron.. 11 [1919), No. 2, pp. 

 76-78). — In this paper, a contribution from the University of Alberta, the author 



notes t! tturrence of dwarf plants in a head row of Marquis wheat grown at 



the University of Saskatchewan from seed of typical Marquis plants selected 

 in 1913. The dwarf is described as being about 9 in. in height, while typical 

 Marquis measured as high as 40 in. Head rows from both tall and dwarf 

 plants were grown in 1915 and 1916, it being stated that "all observations 

 seemed to point to the fact that this dwarf condition was a simple dominant 

 to tallnoss, despite the fact that the original parent was to all intents and pur- 

 poses a normal tall." 



Although Marquis wheat was derived from a cross between a dwarf Indian 

 wheat, known as Hard Red Calcutta, and Red Fife, it is regarded ;l s ques- 

 tionable whether the dwarfness observed in the cultures noted above can be 

 attributed to the Indian ancestor. Dwarf forms occurred frequently in 

 Marquis in 191-1, 1915, and 1916, and in other varieties of wheat similarly 

 treated, including Red Fife. 



Russian wheat, L. Felde (Le B16 Russe. Lausanne and Paris: LiUr. Payot 

 d Co., 1917, pp. 158, pis. 2, figs. 6; rev. in Science, n. set:, 48 (1918), No. 1240, pp. 

 336, 337). — This paper deals with the production and export of Russian wheat, 

 including a rather detailed discussion of soil, climatic, technical, and social con- 

 ditions pertaining to wheat production, and of all phases of internal and external 

 transport, with particular reference to exports to Switzerland. 



Wheat growing- and wheat experiments (Union So. Africa, Dipt. Agr. Local 

 Ser. No. 23 (1918), pp. 38). — This briefly describes cultural, fertilizer, and 

 variety tests with wheat in South Africa. 



Seed Reporter (U. S. Dcpt. Agr., Seed Rptr., 2 (1919), No. 10, pp. 8, figs. 4).— 

 The principal features of this number include observations on European seed 

 conditions, as reported by A. J. Pieters and W. A. Wheeler, and tentative seed 

 production and consumption maps showing the counties of the United States 

 reported as normally producing either a surplus, a sufficient, or an insufficient 

 quantity of Siberian millet, Japanese millet, sumac sorgo, and Sudan grass 

 seed as compared with the planting requirements of each county. 



Market conditions relating to various kinds of field seeds In five geographical 

 divisions are noted, together with information regardng the movement and 

 supplies of soy beans, cowpeas, and velvet beans, and wholesale and retail 

 selling prices of 30 kinds of field seeds about March 20, 1919. Tabular data 

 are also presented showing the average percentage of different varieties of soy 

 beans and cowpeas normally handled by wholesale and retail dealers, together 

 with the amount normally shipped out from producing sections by local ship- 

 pers for a number of States. 



The advantages to the farmer in buying labeled seed only are briefly dis- 

 cussed by E. Brown. 



The usual statistics relating to imports of forage plant seeds permitted entry 

 into the United States are included. 



Agricultural seed inspected in March and April. 1918. OL P. Smuh i Mary- 

 land Sta. Bui. 224 (1918), pp. 127-1 55).— This bulletin reports the results of 

 purity and germination tests with 7J5 official samples of agricultural seeds 

 collected during March and April, 1918, showing the values given on the tags 

 and those found by examination.
