On the subject of protection and attraction of birds about the home, 
among the great mass of literature available, the following can be specially 
recommended: 
How to attract and protect wild birds, by Martin Hiesmann: Witherby & Co., London, 
Is. 6d. 
This is an extended account of the methods pursued by Baron Berlepsch in 
Germany and gives innumerable methods by which the end can be obtained on both 
large and small estates. 
Wild bird guests, by Harold Baynes: E. P. Dutton & Co., 1915, $2. 
This gives a most interesting and readable account of the method pursued by 
the writer and his friends whereby they made Meriden, New Hampshire, a veritable 
model bird village, where the birds became as familiar and friendly as household pets, 
coming when called and alighting freely upon the person. It is beautifully illustrated 
with innumerable photographs showing both methods and results. 
The domestic cat, by Edward H. Forbush, State Ornithologist, Mass.: State Board of 
Agriculture, Bulletin No. 2, 1916. 
This is an exhaustive treatment of the house cat in its relation to wild bird life. 
Bird houses and how to build them, by Ned Dearborn: United States Department of 
Agriculture, Farmer’s Bulletin No. 609. Address Department of Public Documents, 
Washington, D.C. Cost about ten cents. 
On the subject of the English Sparrow as a pest the following can be 
recommended: 
The English Sparrow in North America, by Walter B. Barrows: Bull. No. i, U.S. Dept: 
of Agriculture, 1889, pp. 405. 
How to destroy the English Sparrow, by Ned Dearborn: Farmer’s Bulletin No. 383, 
U.S. Dept. of Agriculture, 1910. 
The English Sparrow as a pest, by Ned Dearborn: Farmer’s Bulletin No. 493, U.S. Dept. 
of Agriculture, 1912. 
These reports give the English Sparrow a fair trial and an honest conviction, and 
suggest various means of keeping its number under control. 
KEY TO THE BIRDS OF EASTERN CANADA. 
Explanation. 
In zoological descriptions a “‘ key ”’ is a device through which a speci- 
men can be gradually referred from larger to smaller groups by picking 
out salient characters and its specific identity thus finally fixed. 
The key here published is a modification of one originated by Mr. 
Frank Chapman and Ernest Thompson Seton and published in the former’s 
‘‘ Handbook to the birds of eastern North America.” It is hoped that 
it will be found of great assistance to the beginner. One advantage of 
this key is that it is independent of the varying characters of age, sex, or 
season, and may be used for juveniles and females as well as adult male 
specimens.
