figs. 29; 11, pp. 18, fig. 1; 18, pp. 21, fig. 1). — These bulletins comprise lessons, 

 prepared for the purpose of giving teachers in the rural and graded schools of 

 Iowa a sufficient knowledge of agriculture to meet the requirements of the 

 school law and of supplying outlines showing what to teach and how the 

 material can best be presented. The lessons deal with the cultivation, history, 

 distribution, improvement, varieties, etc., of the principal grain crops, the 

 cultivation of potatoes, the home garden, fruit growing, trees on the farm, plan- 

 ning and planting the farmstead, legumes, forage crops, plant diseases and 

 injurious and beneficial insects, weeds, fertilizers, and crop rotations. 



Productive farm crops, E. G. Montgomery {Philadelphia and London: J. B. 

 Lippincott Co., 1916, pp. XIX +501, pi. 1, figs. 205).— This book was written to 

 meet the needs of students having some practical knowledge of crop production 

 in agricultural short courses and secondary schools and of beginners in agri- 

 cultural colleges. Because of its practical nature it may also be used as a handy 

 reference book for farmers. Tiie author has endeavored to develop the funda- 

 mental principles of crop production as demonstrated by practical experience, 

 dealing with the classification, origin, distribution, growth, cultivation, insects 

 and diseases, harvesting, and utilization of field crops in general as well as of 

 individual crops. Practical exercises and review questions are included in 

 each chapter. Data as to local weeds, market grades of hay and straw, and 

 grades of grain are appended. 



The small grains, M. A. Carleton (A^Cfr York: The Macmillan Co., 1916. pp. 

 XXXII-j-699, pi. 1, figs. 183). — This book is intended primarily for instruction 

 in colleges and universities, but is also adapted for use in agricultural short 

 courses, in academies and high schools, and by farmers and general readers. 

 After a brief discussion of the fundamental principles of plant structure and 

 nutrition, as related to cereals, the four principal cereals are treated separately 

 and from the individual plant standpoint as to their origin, characteristics, 

 classification, varieties, selection, and hybridization. Then, to avoid duplica- 

 tion, these cereals are treated together with reference to the further subjects 

 of soil and climatic relations, acclimatization, cultivation, irrigation, weeds, 

 insect and fungus pests, and uses. Buckwheat and rice, being botanically dif- 

 ferent from the four cereals referred to, are treated separately as to all topics. 

 An extended bibliography is appended. 



Corn and cotton, edited by C. A. McMurry (Peahody Col. Bui., 1 {1915), No. 

 2. pp. ^8). — This pamphlet contains studies of the history, production, improve- 

 ment, and uses of corn and cotton, the marketing and manufacture of the latter, 

 competition in the manufacture of cotton goods, and references to literature on 

 these subjects. The pamphlet is designed for the use of teachers and includes 

 suggestions on methods, but is simple enough to be used by children as a text. 



Weeds, L. G. Atherton {Normal Teacher [Madison, 8. Dak.], 5 {1915), No. 6, 

 pp. 31, figs. 13). — This is a suggestive outline for the use of teachers in the 

 introduction of the study of weeds in rural and village schools. 



Laboratory manual in g'eneral microbiology, W. Giltner et al. {Neiv York: 

 John Wiley and Sons, 1916, pp. XVI+^IS, pi. 1. figs. 97). — This laboratory guide 

 is based on the work of instructors at the Michigan College for over a decade 

 and consists of three parts. The purpose of part 1 is primarily to give a work- 

 ing knowledge of laboratory methods used in the study of microorganisms, 

 wolds, yeasts, and bacteria being taken up in the order of their comparative 

 size and studied as to their identification by morphological and cultural 

 methods; part 2 consists of exercises demonstrating the various physiological 

 activities of micro-organisms ; and part 3 deals with applied microbiology. An 

 appendix contains an outline for the study of microbiology, data on media, 

 solutions, stains, etc., and a list of text and reference books.
