GRAY WOLVES AND COYOTES 241 
“Summary of Conclusions—(1) Prairie coyotes 
will not willingly jump over a fence above 30 inches 
in height. r 
‘*(2) They will readily climb over fences built of 
horizontal rails or crossbars, especially in order to 
escape from captivity. 
‘*(3) Barbed wires do not deter them from crawl- 
ing through a fence to escape. 
**(4) Woven-wire fences should have meshes, when 
rectangular, less than 6 by 6 inches to keep out 
coyotes. For such fences triangular meshes are much 
better than square ones. 
**(5) In fencing against coyotes with woven fences 
care must be used to see that there are no openings 
at the ground through which the animals can force 
themselves, since they are more likely to crawl under 
a fence than to jump over it. 
““(6) It seems reasonably certain that a fence con- 
structed of woven wire with a triangular mesh not 
over 6 inches across and having a height of 28 to 42 
inches, supplemented by two or three tightly stretched 
barbed wires, would prove to be coyote-proof. It is 
difficult to make exact estimates of the cost. ‘Woven 
fences differ in weight, price, and durability, and 
freight charges on materials depend on the distance 
from distributing points. The cost of posts and labor 
varies much. An estimate based on so many variable 
factors is of little value, but an average of $200 per 
mile would probably allow the use of the best ma- 
terials.”’
