Perhaps the warning cry of a bird or the suspicious rustling of our footsteps in the tall grass, but at any rate the herd began to move slowly away.

Two of the larger groups marched solemnly down the slope away from us and the other disappeared among the low scrub trees to our right.

We followed the two larger groups and soon were again within a few yards of them.

An ant-hill four or five feet high gave us some protection, and over the top of this we watched the enormous animals as they stood under the trees ahead of us.

While watching these two large groups we forgot about the one that had disappeared to the right.
Suddenly one of the gunbearers whispered a warning and we turned to see this group only a few yards from us and bearing directly down toward the ant-hill where we crouched in the grass.
