 Jersey Agric. Expt. Sta., 1913, New Brunswick, 1914, pp. 719-789, 

 2 plates. 



Included in this report are detailed accounts of the salt-marsh 

 mosquito work, ditch cleaning, etc., and several problems connected 

 therewith are discussed ; reports of the various county mosquito

 appended. The report concludes with a brief account of the 

 mosquitos reported during the year, including : Ochlerotatus (Aedes)

The mere fact of the publication of such a book as this is 

 evidence of the great and increasing interest now being taken in 

 economic entomology and especially in that part of it which inti- 

 mately concerns man himself. This book is not intended to be a 

 treatise on the relation of insects to disease nor has any attempt 

 been made to deal with all possible pests, but it has been written 

 particularly for those seeking information regarding household pests 

 and practical methods of controlling them. Technicalities have 

 therefore been avoided, whilst every effort has been made to 

 secure accuracy. The illustrations, though many of them would 

 hardly satisfy the systematic entomologist, will serve their purpose. 

 Under each pest, references are given to the principal American 

 literature and to other more or less readily accessible books with a 

 view to helping those in search of further information. A chapter 

 on poisonous insects and Arachnids explains the nature and the effects 

 of the bites of spiders, ticks, centipedes, etc., and of a number of insects 

 and caterpillars, the handhng of which may have more or less un- 

 pleasant consequences. The opportunity is taken to point out that 

 a large number of supposed dangerous insects are either quite harmless 

 -or practically so. The last chapter deals with the use of gases against 

 household insects, no less than 11 pages being devoted to the use of 

 hydrocyanic acid. Though all necessary and proper warning is given 

 of the deadly character of this gas and of the material from which 

 it is produced, the author says that despite this " he does not beheve 

 that any careful, thoughtful person should be deterred from employing 

 this method of controlling household pests." The recommendation 

 of this insecticide in American works on Economic Entomology ex- 

 hibits a remarkable faith in the existence of care and thought amongst 

 persons devoid of the most elementary knowledge of laboratory 

 manipulation. 



The book is written in a simple and easy style, and should be the 

 means of spreading useful and necessary knowledge amongst those 

 for whom it is intended.
