different heights. And so the journeys continue, first east, then 

 west, south or north, as the wind varies. At night they apparently 

 drop to earth* to infest new neighbourhoods or perchance rise 

 and move elsewhere next day. But not all go, among the 

 Orthoptera especially Nature has made a wise provision. Some 

 are endowed with long wings; these are built specially for loco- 

 motion and conveying the insect long distances. Others of the 

 same species have short or rudimentery wings which oblige them 

 to stay at home. So that while the long-winged forms seek new 

 homes, there are enough short-winged brothers and sisters to 

 carrv on the family at home and incidently the work of destruc- 

 tion also. 



BOOK NOTICE. 



Distribution and Migration of North American Shore 

 Birds. By Wells W. Cooke, U. S. Department of Agriculture, 

 Biological Survey, Btilletin No. 35, 100 pages and four half- 

 tone plates, by Fuertes. 



This publication is another valuable contribution towards a 

 knowledge of the habits of North American birds. It deals, as 

 the title indicates, with distribution, breeding range and migra- 

 tion, and also touches upon the economic side of the question 

 which has hitherto received very little attention. The author 

 claims that, so far as present knowledge goes, the evidence of 

 food eaten is wholly in the birds favour, as no shore bird has yet 

 been discovered to do harm to any appreciable extent ; while 

 many, such as the Upland Plover and Kill deer are of very great 

 use to agriculture in destroying noxious insects. A special plea 

 is made for the general protection of all shore birds in spring 

 time, especially the Golden Plover, which is in a fair way to join- 

 ing other extinct species. 



The book is throughout an extremely useful work, covering, 

 as it does, the range both winter and summer of birds in- 

 habiting the whole of North America.

*It is well known that some grasshoppers travel throughout the 

 n'ght. Such an instance is related by Prof. S. J. Hunter of Dissostrira 

 lon<'Je>''ntf',s, and though I have no direct evidence, it is possible that some 

 of the Manitoba species are also nocturnal during the migratory season.
