GRAY WOLVES AND COYOTES 241 



"Summary of Conclusions. (1) Prairie coyotes 

 will not willingly jump over a fence above 30 inches 

 in height. 



" (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,'"
