author concludes from his examination of the evidence that cultivated rye (Secale cereale L.) 

 originated from Secale anatolicum Boissier and came into cultivation in Turkestan. — R. M,

 (Pyrenees-orientales). [Analyses of sorghums and sweet corns cultivated in Palau-del-Vidre 

 (Eastern Pyrenees).] Ann. Sci. Agron. Frangaise et Etrangere 37: 173-184. 1920. — Analyses 

 of the 5 varieties of sorghum and 4 varieties of maize grown experimentally [see Bot. Absts 10, 

 Entry 1505] are reported. The sorghum yielded per hectare as much as 6200 kgr. sugar, 

 corresponding to 3750 1. of alcohol, a good quality being obtained without rectification. The 

 pressed pulp may be used as cattle food, and also has possibilities for paper mailing. Sweet 

 corns are less promising than sorghums because of smaller yield, smaller sugar content, and 

 more difficult preservation, both in the field and after harvest. — A. B. Beaumont.

 and cotton. Jour. Elisha Mitchell Sci. Soc. 36: 16. 1920. — Heavy applications of soluble 

 mineral fertilizers cause greater delay in germination. Organic fertilizers cause greater 

 injury to the seedlings. Very small amounts of borax cause almost complete chlorosis of 

 corn seedlings. — W. C. Coker.

 Nacion. Ganaderia y Agric. [Uruguay] Bol. 37. 21 p. 1920. — The following oil producing 

 plants can be successfully grown in Uruguay: peanut, sunflower, cotton, rape, soy bean, castor 

 bean, and Sesamum orientate. Brief cultural directions are given for each, including recom- 

 mended varieties, seeding, cultivation, and harvesting. — John A. Stevenson.

 Exp. Sta. 1918: 54-71. PI. 5-6. 1920. — Rye winter killed badly. Spring grains were seeded 

 May 26-30, the late spring following an unusually cold winter. Grain following grain matured 

 earlier but produced less than grain following other cultivated crops; the yield was better 

 following clover but endangered by lodging or early frosts. Comparisons of grain selections 

 are given for breeding plats as well as for increase plats. Of new Varieties, 1 of barley and 

 4 of wheat were received from the U. S. A. and Canada, and 4 of barley from Rampert. Some 

 work was done in alfalfa selection. Twenty-three varieties of potatoes were tested. Pota- 

 toes on south slopes were better than those on north slopes; potatoes with the tops cut off 

 when frosted August 26 yielded less than when the tops were left on until digging time. Tur- 

 nips, carrots, and sugar beets comprised the root crops grown. Strawberries were a failure 

 owing to winter injury. Red raspberries are being tried. — /. P. Anderson.

 Exp. Sta. 1919: 44r-55. PI. 7~13. 1920. — Yields of wheat and Canadian oats are reported 

 and a table on variety tests of barley and oats is given. Potatoes, sugar beets, carrots, turnips 

 field peas, sunflowers, and red clover were grown. Hansen's Semipalatinsk alfalfa has with- 

 stood 4 winters, but other kinds have not proved so hardy. — /. P. Anderson.

 Africa. II. Rhodes grass (Chloris gayana Kuth). Jour. Dept. Agric. Union of South Africa 

 3: 136-141. 2 fig. 1921. — Rhodes grass, a native of South Africa, was first brought into culti- 

 vation by Cecil Rhodes. It is a perennial, mainly a summer grass, requiring a summer rain- 

 fall, and will not withstand protracted drought or very severe cold. It is an excellent pasture 

 and hay grass and palatable to all kinds of stock, thus comparing favorably with Teff and 

 Kikuyu. — E. M. Doidge.

 tobacco and this is generally true in the Magaliesberg, Kat River, and Oudtshoorn areas. 

 Several types of soils are considered suitable; black turf gives good results but is inclined to
