THE WILD MAMMALS OF THE FARM 



lOI 



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. 



2. A map of the fami, with the location of typical haunts 

 of the different species studied indicated upon it. 



Fig. 49. Spring pole and snare: 

 A, its setting; the pole is a 

 lithe sapling, trimmed and 

 bent, its top held down 

 by a line, /, attached to a 

 trigger in a hole in the post,^. 

 Fast to the line is the slip- 

 noose, n (most quickly made 

 of small annealed brass wire), 

 which is set across the rab- 

 bit's path in such a position 

 that the rabbit will push his 

 head through it when reach- 

 ing the bait, B. T illustrates 

 how the trigger t is set ma 

 ^ inch hole in the post. The 

 slightest movement of the 

 bait-stick rolls the ball, re- 

 leases the line, ^ and liberates 

 the pole to draw the noose.
