sheltering piece of bark or a flat stone, supported an inch or 

 more, allowing easy access. A few snares of the simple sort 



illustrated in fig. 49 (or of some 

 better sort known to any member 

 of the class) may be set in the 

 briar patch in the runways of rab- 

 bits or in the mouths of their bur- 

 rows. 



2. Such animals as the traps 

 contain, together with such others 

 as are provided, living or dead or 

 represented by tanned skins are to 

 be compared and their characters 

 are to be written in a table pre- 

 pared with headings as indicated 

 on pages 102 and 103. Fill out the 

 table in full, but distinguish in it 

 between original observations and 

 borrowed data. 



The record of this study will 

 consist in: 



I. The completed table, as indi- ■ 

 cated above.
