THE WILD MAMMALS OF THE FARM 101 
sheltering piece of bark or a flat stone, supported an inch or 
more, allowing easy access. A few snares of the simple sort 
Fic. 49. Spring pole and snare: 
A, its setting; the pole is a 
lithe sapling, trimmed and 
bent, its top held down 
by a line, J, attached to a 
trigger ina hole in the post, p. 
Fast to the line is the slip- 
noose, x (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 ¢ is set in a 
5% inch hole in the post. The 
slightest movement of the 
bait-stick rolls the ball, re- 
leases the line, J, and liberates 
the pole to draw the noose. 
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- 
TOWS. 
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: 
1. The completed table, as indi- 
cated above. 
2. Amap of the farm, with the location of typical haunts 
of the different species studied indicated upon it.
