trict. There is a good index and a list of the scientific names 

 used, at the end of the book, which is an important matter to a 

 work of this kind and, in saying that Mr. Saunders has ably per- 

 formed a tedious but much needed task, we feel that we are 

 simply just without being at all generous. Considering the quan- 

 tity and quality of this class of work it may be thought difficult 

 to produce a striking addition to our literature of the subject, 

 but Mr. Saunders has succeeded in doing this and since the pub- 

 lication of the late Dr. Harris's Treatise on Insects Injurious to 

 Vegetation, which has become a classic, nothing has appeared so 

 useful and readable, so free from objectionable and useless niatter, 

 in such equally good taste as Mr. Saunders' ^'olume on Insects 

 Injurious to Fruit The book will find its way, undoubtedly, into 

 many hands and will add to the solid esteem in which its author 

 is held by all who have benefited by his scientific labors or his 

 personal friendship. Mr, Saunders' book is like himself, good, 

 solid, sincere and useful, utterly devoid of humbug and clap-trap, 

 deserving of the commendation of every conscientious thinker 

 and worker the world over. A. R. Grote. 



A NEW PRINCIPLE IN PROTECTION FROM IxNSECT ATTACK. 



Under this caption Prof. J. A. Lintner claims originality for 

 the idea that by deodorizing plants they will be saved from being 

 the depositories of the eggs of insects. The pamphlet is nicely 

 written, but contains no details of experiments to justify the 

 author's claim, the originality of which seems unimportant in the 

 face of the fact that practically that is what is effected by the 

 use of many remedies against injurious insects. The pamphlet 

 is occupied by an ex parte argument as to the sense of smell in 

 insects, of which no one has publicly, we think, denied the exist- 

 ence. It is certainly not to sight that moths owe the finding of 

 plants in the darkness on which to oviposit. What is needed in 

 the use of preventatives just now is systematic action and co-opera- 

 tion. The labor of one farmer is neutralized by the idleness of his 

 neighbor and injurious insects are harbored next door to where 

 they are constantly being driven out. The remedy is the education 

 of the rising generation. If, in the common schools throughout 

 the country districts, practical entomology were taught in a simple 

 elementary manner we should soon see a different state of affairs, 

 then the young farmers would probably take the nests of the apple 

 tree tent caterpillar in time, instead of those of the robin, and we 

 should have more birds and less noxious insects. Professor Lint- 

 ner's pamphlet is an addition to the theoretical discussion of 

 Economic Entomology and will no doubt be read with interest in 

 certain quarters. A. R. Grote.
