ordinances and laws are useful. Entomologists and others interested 

 in bettering sanitary conditions might well turn their attention to 

 this phase of the problem, since even the possibihty of coercion proves 

 a powerful stimulant to many who would otherwise be indifferent.

Elementary Entomology, by E. Dwight Sanderson and C, F. 

 Jackson, pages 372, figures 496. 1912. 



The volume under consideration may Be characterized as an excellent, profusely 

 illustrated elementary entomology, admirably adapted to the needs of those interested 

 or likely to become interested in the elementary or economic phases of the Science. 



With less than 400 pages and nearly 500 text illustrations, the need of condensa- 

 tion is evident. Some 3.5 pages are devoted to a discussion of the external and inter- 

 nal anatomy, 22 pages illustrate growth and transformations, while over haK the 

 volume, about 200 pages, outline briefly the salient characteristics of the more 

 important groups and incidentally notice many injurious forms. Scattered through- 

 out the work there is much.biological information, the value of the latter being greatly 

 enhanced by the numerous figures of early stages in connection with those of the 

 adult insect. 



The laboratory work provides for the anatomical study and comparison of several 

 typical forms and for biological work with aphids, the cabbage butterfly and the 

 fruit fly. The keys to the orders and the more important families make it possible 

 for students using this volume to become well acquainted with the entire group. 



The authors have been successful in producing an admirable volume, small in size 

 and moderate in price, which will appeal strongly to all having charge of elementary 

 students in entomology. The paper is excellent, the printing clear, the figures 

 distinct and the general appearance of the work most attractive. 



The Wheat-Head Army- Worm as a Timothy Pest, by R. L. Web- 

 ster, Iowa Agricultural Experiment Station, Bulletin 122, pages 

 323-348. 1911. 



The author gives an excellent comprehensive account of a timothy pest, Meliana 

 abilinea. The discussion of control measures immediately following the character- 

 ization of the injury is a commendable feature in popular bulletins. The author ad- 

 vises clean culture, fall plowing and early fall pasturing. There is an excellent 

 bibhography, a full life history and concise descriptions of the various larval stages. 

 The excellent paper brings out the illustrations in a very satisfactory manner.
