MAMMALS. 



133 



I have met with several 

 homes of blackbirds and 



for breeding purposes. 

 in the disused old 

 thrushes. 



During last spring we left our artificial tree- 

 trunk rolled up in a friend's garden for a week 

 or so and when we came to use it a'ain found 



BAT. 



a beautiful mouse's nest inside it. Our interest 

 however, in the structure was rather cooled by the 

 discovery that it was composed in great part of 

 the strings with which we tied the various parts 

 of our contrivance together. 



Bats both great and small are to be met with 

 in most parts of the country where trees prevail, 

 and may be photographed in their dismal hiding- 

 quarters by the aid of magnesium flashlight.
