The spell was broken by shouts down the mountain, and presently Dr. Post appeared with the other American party, and altogether we studied the features of the mountain and the plain as related to each other. Looking over the edge of the cliff, we could see how perfectly it answered to the description of "the mount that might be touched," for the plain came up to its very base, and at the same time there were low-lying mounds at the foot, which seemed to mark where bounds had been set against too near an approach.
