The cost of construction varied from $320 to $400 per mile. Galvanized wire was used, and of the barbed the thickest-set four-pointed wire obtainable. If four-point wire could be had, with sharp points set not over 2 inches apart, the top wire might be dispensed with. While this fence was begun in 1897, it was net finished until three years ago. It was partly experimental at first, and at the end of the second year only that portion of the range used for lambing was inclosed with a coyote-proof fence. We do not know that a coyote has ever scaled or jumped it. A very large coyote that got in through an accidentally 'propped' floodgate, though chased by dogs all day, could not be made to jump out, even when cornered. Considering the steep, wild, and broken nature of the country, with several 'slides' in the fence that could not be avoided when building, and which move and displace the fence during hard storms, it is net surprising that a few coyotes have gotten in. Fortunately, partition fences have aided in the capture of those before much damage was done. Two obstacles are encountered in keeping up this fence--trespassers, who cut or break a picket to get through, and slides. Coyotes are very persistent, and when they see young lambs on the opposite side will follow the fence for miles, trying to find a hole. * * * None have gotten in this season. When we began to fence against them the coyotes wore literally driving sheep out of the country. * * * Horses and cattle have taken their places, but return less than half the profit sheep did prior to the coyote's inroads. Excessive rains in winter and irregularity of landscape preclude the practicability of close herding. With us it was either abandon sheep or fence the pest out. Fortunately we adopted the latter. While the fence used by Mr. Clarke is expensive, the complete success of his experiment is of much interest. In most parts of the West woven wire would be cheaper than pickets and would require less labor in its erection. Where the land is as uneven as that just described, the use of woven wire may be impracticable. Mr. D. W. Hilderbrand, of California, who has built coyote fences for ranchmen in the San Joaquin Valley, recommends a 3-inch mesh woven wire fence 36 to 40 inches in height, with two barbed wires on top, 5½ inches apart, and one at the bottom. He recommends that the posts be set 20 to 30 feet apart.
