From data now available it seems reasonably certain that a fence constructed of woven wire with a triangular mesh not over 6 inches across, and of 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 materials. Further experiments with wire fences will be made by the Biological Survey in cooperation with sheep growers in the West, and the results will be given to the public as early as practicable. The matter is one of great economic importance, and the Survey will welcome correspondence with persons interested in the subject. * * * * * Transcriber's Note The total number of coyotes in the table on page 10 was changed to match the sum of the numbers in the table.
