For most of the time the stillness was profound. The oxen had lain down within the enclosure and were either chewing their cuds or sleeping. Two or three of the horses kept their feet, but most of them were also lying down. Occasionally the stamp of a hoof sounded dully, but nothing else disturbed the watchers. In all directions on the level plain reigned the silence of the grave. The wide sweeping Platte, though not far off, coursed between its banks with no ripple or eddy that could be heard a hundred yards away. It was hard to believe that men were abroad in this silent world, hunting for a chance to slay their fellow creatures, but such was undoubtedly the fact.
