and sometimes wholly destroyed by the ravages of insects. The book is 

 remarkably well-planned and covers the whole held, including House- 

 hold Pests, Insects and Disease, Beneficial 'Insects, Insecticidal 

 Methods, etc. There are also interesting chapters on subjects not 

 usually incorporated into such works, such as, Means of Defence in 

 Insects; Communication Among Insects; Tropisms; Symbiosis and 

 Parasitism ; The Balance of Life. 



We consider this one of the best books ever published on the sub- 

 ject and a credit to the author and the Government of Madras. We 

 have foregone the pleasure of looking for or finding a typographical 

 error or some slight mistake, which probably makes the review in- 

 complete, but the good is there in great abundance. H. S. (./</</.) 



INSECTS INJURIOUS TO THE HOUSEHOLD. By GLENN W. HERRICK, 

 Professor of Economic Entomology in the New York State 

 College of Agriculture at Cornell University. The Macmillan 

 Company, New York. Price, $i-75- 47 pages and 152 illus- 

 trations. 



If one judges from the requests for information that come to scien- 

 tific institutions, a work of this kind is urgently needed. Very few 

 householders, if any, escape insect pests of one kind or another and 

 up-to-date, authoritative information will now be available to the 

 public. While the work is not intended as a treatise on insects in re- 

 lation to disease, there are admirable chapters on some of these 

 pests. A valuable feature of the book is the bibliography following 

 each chapter. Each of the seventeen chapters deals with a group 

 of insects having related activities. This is illustrated by the chap- 

 ters on insects injurious to clothes and carpets ; ants and their ac- 

 tivities and invasions of the household. We consider this one of 

 the most useful of the recent books on economic entomology or its 

 subdivisions. H. S. (Advertisement.} 



MANUAL OF FRUIT INSECTS. By the late MARK VERNON SLINGERLAND 

 and CYRUS RICHARD CROSBY. The Macmillan Company, New 

 York. Price, $2.00. 



The junior author states that the book in part is the result of 

 nearly twenty years' work by Professor Slingerland in studying the 

 insect problems of the fruit-growers of New York State. The more 

 important insect pests of deciduous trees are treated and minor pests 

 altogether omitted. The means of control are given from the stand- 

 point of the commercial fruit-grower. Most of the illustrations are 

 from photographs by Professor Slingerland. There are 492 pages, 

 396 illustrations and an index of the names of the insects treated. 

 The fruit insects make a rather compact group and lend themselves 

 very well to special treatment. There are professional growers who 

 would find such a work valuable to them and it will also appeal to 

 the suburbanite who has fruit trees around his home. The illustra- 

 tions are generally satisfactory and in some cases excellent. Some 

 of them lend themselves better to half-tone illustration than others 

 Prof. Slingerland was an expert on insect photography. The junior 

 author has accomplished a valuable piece of work in bringing to 

 light these researches of Prof. Slingerland. H. S.
