selection is also outlined. The important factors to be considered in making selections in 

 kaoliang breeding are: Sugar content, earliness, disease resistance, drought resistance, pro- 

 ductiveness, erectness, and shape. — Chunjen C. Chen.

 1920. — Waste land is reclaimed in South England and Belgium for agriculture, forestry, and 

 fisheries. Winter wheat, spring oats, turnips, rape, buckwheat, and potatoes are favorite 

 first crops. Pine, larch, spruce, and poplar are more commonly used in tree plantings. 

 Where fish are grown in shallow ponds, which are drained and cultivated every third year, 

 an unusual rotation of fish and oats occurs. — H. V. Harlan.

 Exp. Sta. Bull. 143. 8 p., 1 fig. 1920.— Yields of varieties Red Bobs, Prelude, Ruby, Kitch- 

 ener, Pioneer, and Marquis are given and also amounts of stem rust {Puccinia graminis)

 Early maturing and non-shattering varieties of oats and barley are grown, also grasses and 

 white and red clovers. The Sandy variety of oats and 6-rowed barley, which are early matur- 

 ing and non-shattering, are grown. The "Up-to-date," Abundance, and British Queen varie- 

 ties of potatoes are cultivated. — H. V. Harlan.

 £60 p., 186 fig. Ginn and Company: Boston, 1920. — This book, which is designed to interest 

 and enlighten the very young agriculturists of the country, relates the story of corn and its 

 culture in a simple, readable style. At the conclusion of each chapter the important facts 

 contained therein are brought out by questions. — C. V. Piper. 



53. Yeh, Yuen Ting. [Standard varieties of American cotton and selection.] Hua- 

 Shang-Sha-Chang-Lien-Ho-Hui-Ki-Kau [China Cotton Jour.] 1*: 235-245. 1920.— Methods 

 are discussed and described of maintaining the purity of cotton varieties developed by the 

 U. S. Department of Agriculture through selection. Outlines of 5-year system in mass 

 selection and 7-year system in progeny selection for use in China are given. A descriptive 

 table is given of the characteristics of Acala, Columbia, Durango, King, Lone Star, and 

 Trice. — Chunjen C. Chen. 



54. Yeh, Yuen Ting. [A study of cotton production in China.] Hua-Shang-Sha-Chang- 

 Lien-Ho-Hui-Ki-Kau [China Cotton Jour.] 12:233-241; P: 221-236. 1920.— The author 

 reports a two months' investigation of the Chinese cotton-growing situation made in the 

 summer of 1919 with Mr. O. F. Cook, U. S. Department of Agriculture. Nine provinces were 

 surveyed: Kiangsu, Chekiang, Anhwei, Shantung, Chihli, Honan, Hunan, Hupeh, and 

 Kiangsi. The climate of the northern part of the region is dry, while the southern part is wet. 

 The soils vary from heavy clays to sandy loams. Mass planting is the common practise, 

 though row-planting is used to some extent. American varieties are quite common through- 

 out the region. Chinese cotton is of two kinds, brown and white. American cotton consists 

 mostly of the following varieties distributed by the U. S. Department of Agriculture: Lone 

 Star, Trice, King, Acala, Durango, Columbia, Egyptian, and Sea Island. A species of 

 Chinese Upland cotton was observed but no record of its origin was found. The provinces 

 of Chihli, Honan, Shansi, Shensi, and Shantung are said to be suited to growing American 

 cotton. The following cotton insects were observed: Bollworm, pinkworm, leaf -hopper, red 

 spider, cutworm, and cotton caterpillar. Diseases noted were anthracnose, rust, shedding of 

 bolls, angular leaf spot, and damping-off. Five governmental cotton stations and 9 private 

 stations visited by the author are listed. Suggestions for improving Chinese cotton are 

 given: (1) Careful selection and variety test; (2) close planting and late chopping; (3) deep 

 plowing and frequent cultivating; (4) better drainage in the southern region; and (5) Trice 

 is considered to be adaptable in China. — Chunjen C. Chen.
