reports from many persons who have provided the birds with Jacob 

 Martin houses. 



These are accompanied by comment and annotations by the 

 author, and the text is profusely illustrated with halftone reproductions 

 of bird -houses in position. 



Among the annotations commenting on reports will be found hints 

 and items of interest and value to Martin lovers. Special attention is 

 called to the remarks on protecting occupants of houses mounted on 

 wood poles or trees, from the ravages of cats, squirrels and other 

 destructive animals and snakes. In the latter connection particular 

 attention is pointed to Mr. \V. Scott Way's experience with destruc- 

 tive black snakes and the author's lengthy annotation on the destruc- 

 tion of birds by snakes, and the real or fancied supposition of the 

 snake's power to "charm" its intended victim. 



The Third Supplement will be issued November i, 191 1, when 

 the author hopes to enlarge the work by adding further useful informa- 

 tion and more interesting reports from purchasers of Martin-houses 

 and halftone reproductions of houses in position.
