Thompson 126. Grand Canyon July 9, 1931 Interview with Brooks Possible means of making a living after the park construct- works have reached its culmination. Brooks thinks that it would make no difference if the Indians did get a few antelope; he could live them off into reasonable hunting, as they have always been willing to cooperate. The mule sheep (Ovis canadensis) in the canyon get along all right, but Brooks thinks the Bobcats keeps the lambs down. He says the canyon is full of Bob-cats. He also thinks they get some of the Durango grouse or the Kaibali. There are not many grouse. The Burros are nearly gone from the canyon, although there are on the north side of the canyon than on the south. The Kaibali Deer story, according to Brooks is as follows: There were not many deer there to begin with. But 50 or 60 years ago cattle were put in north of the plateau. By 1900 the summer grass range was pretty well gone, and the cattle were driven up into the forest.
