An Indian warrior having swum the stream, stood for a moment on the shore. He was afoot, a fact which surprised the watcher, who knew that none of his race wandered far in that country without a pony to carry him. Standing thus, the redskin emitted a soft bird-like call which the listening ear could hardly detect. The response was in the form of a second Indian, who came into sight from some point up stream. The two met and talked in voices which were only the faintest murmur to the eavesdropper.
