compact, comprehensive and well illustrated manual entitled "Breves 

 Instrucciones para la Recoleccion, Conservacion y Envio de Ejemplares 

 de Historia Natural Para los Museos." In this manual he includes 

 illustrations and instructions covering virtually the whole animal king- 

 dom, and adds seven pages on botany and nine on geology. The portion 

 on Entomology is full and well illustrated. This is evidently a third 

 edition of this useful book, the previous editions having been published 

 in 1901 and 1903. 



We have nothing just like this in English, although the U. S. National 

 Museum has published several pamphlets giving directions for collect- 

 ing and preserving different groups. The bringing of all this material 

 together might be advisable, since many people could use such a work. 

 Evidently Professor Porter has found that his manual is of value in 

 South America, as is shown by the necessity for publishing three 

 editions. — L. O. Howard, Washington, D. C. 



Injurious Insects and Useful Birds. Successful Control of 

 Farm Pests. By F. L. Washburn, M.A., Prof, of Entomology, Univ. 

 of Minn. ; Entomologist to the Minn. Exper. Station, and State Ento- 

 mologist ; Fellow of A. A. A. S., Member Amer. Assoc. Econ. Ent. ; 

 Ent. Soc. Amer., Am. Soc. Naturalists, etc. 414 illustrations in text 

 and four colored plates. J. B. Lippincott Company, Philadelphia and 

 London. — Prof. Washburn states that the suggestions in his book are 

 largely the results of twenty-one years of work in Economic Ento- 

 mology. The book is intended for the use of high schools, agricultural 

 colleges, farmers, orchardists, vegetable growers, owners of gardens 

 and housekeepers. The questions at the ends of chapters are useful, 

 and in addition to the usual chapters on insects injurious to vegetation 

 there are chapters on insects affecting man and the household ; insects 

 and insect-like animals attacking stock and poultry. A very valuable 

 feature is the chapter on the relations of birds to agriculture, which is 

 illustrated by the useful birds. The work closes with the chapter on 

 some of the four-footed pests of the farm. This is an all-round good 

 book and we can heartily recommend it. — Henry Skinner. 



Wasp Studies Afield. By Phil Rau and Nellie Rau, with an Intro- 

 duction by William M. Wheeler. Princeton University Press. 

 1918. Price $2.00. 

 We take pleasure in helping to introduce this mightily interesting 

 book. The authors are well known to students of animal behavior for 

 their accuracy in depicting the life and ways of insects. The fact that 

 Prof. Wheeler gives the introduction vouches for the scientific im- 

 portance of the work. The subject, with one or two exceptions, is the
