485. Westbrook, Edison C, and A. B. Hursey. Tobacco culture. Bright leaf or 

 flue-cured tobacco. Georgia State Coll. Agric. Bull. 171. 20 p., 8 fig. 1919.— General instruc- 

 tions for raising and curing tobacco, also plans for making curing houses. — T. H. McHatton. 



486. Wiancko, A. T. How to increase Indiana corn yields. Indiana (Purdue) Agric. 

 Exp. Sta. Circ. 91. 20 p., fig. 1-10. 1919. — General advice is given to farmers relative to corn 

 production in Indiana including choice of variety, improvement of seed by ear-to-row testing, 

 selection and proper storage of seed ears, germination tests to eliminate unsatisfactory ears, 

 rotational practice, soil fertilization, and cultural methods. — Max W. Gardner. 



487. Wiancko, A. T., and C. O. Cromer. Spring small grains in Indiana. Indiana 

 (Purdue) Agric. Exp. Sta. Bull. 225. 20 p., fig. 1-14- 1919.— Comparative yield data secured 

 between 1904 and 1918 at Purdue upon a number of varieties of oats, spring barley, and spring 

 wheat and upon spring emmer and spring rye are presented. Comparison of these with the 

 yields of winter wheat and rye leads to the conclusion that the climate of Indiana is in general 

 too warm for the satisfactory development of spring-sown small grains. In the northern part 

 of the state, oats and barley may be profitably grown. Oats is the principal spring grain grown 

 in Indiana. General data relative to oat culture is given including methods of seed grain 

 disinfection and the results of tests upon different rates of seeding. — Max W. Gardner. 



488. Wiancko, A. T., S. D. Conner, and S. C. Jones. The value of legumes on 

 Indiana soils. Indiana (Purdue) Agric. Exp. Sta. Bull. 226. 20 p., fig. 1-6. 1919.— Out of 

 11,000,000 acres in field crops in Indiana, only 1,000,000 is in legumes. Twenty-five to 50 per 

 cent of the nitrogen and humus of Indiana soils has been used up or lost, and 3,000,000 acres 

 should be annually in legumes. Field tests in eight localities during 12 years show that crop 

 rotations containing legumes resulted in an average increased yield of 4.6 bushels of corn 

 and 4.7 bushels of wheat per acre as compared with rotations in which no legumes were in- 

 cluded. Clover is the most practical legume for use in Indiana. General information relative 

 to clover culture is given. Soy beans or cowpeas may be used on acid soils, alsike on wet 

 soils, and hairy vetch or cowpeas on light sands. — Max W. Gardner.

 cultural and gardening projects, i-xviii+261 p. 142 illustr. J. B. Lippincott Company, 

 Philadelphia and London, 1919. — A volume in the Farm Life Text Series, edited by K. C. 

 Davis. Part I deals with plant life; Part II, with most important families of economic plants, 

 with special exercises. The plan includes three things. First, a brief statement of recog- 

 nized facts and principles concerning plants and plant growth usually given in text-books for 

 secondary schools; second, a list of simple exercises and suggestions for observations, which 

 the pupil can conduct without great difficulty and which will demonstrate many of the state- 

 ments given in the book, and, third, a list of questions intended to be suggestive to the pupil, 

 and to encourage further studies. — C. S. Gager.
