The feeling of the young Express Rider was natural. When drawing near a point where danger is suspected, we prefer to do so at the most guarded pace. With all of Dick’s sagacity he was more likely to go wrong when on a run than when on a walk.

The animal must have felt much as did the trained dog, who, having pointed a bird, was picked up by his new and sympathetic master and carried off the field, under the belief that he had been suddenly taken with cramps. Dick gathered his hoofs several times and broke into an impatient gallop, only to be drawn down again to a trot which finally dropped to a rapid walk. He gave up the dispute in disgust and by his action said:

“All right; if you think you know more than I do, you may run things.”

It did not add to Alden’s serenity of mind to notice that the course was gradually shifting to the left, and finally led directly toward the brush of smoke which still stained the blue tinted sky.

All manner of thoughts crowded upon him. The one hopeful truth was that the living Lightfoot had come over the route unharmed within the last hour. It would seem that Alden ought to be as fortunate as he. Ah! if he had only had time to question the rider who might have passed through a brush with the redskins!

Another fact gave basis for vague hope: a scrutiny of the whole horizon showed no answering signal. When Indians resort to such telegraphy, as they often do on the plains and among the mountains, there are calls and replies. It is on record that on one occasion the news of the signing of an important treaty at Washington affecting the Sioux was known to that tribe before the telegraphic messages could reach the army officers at the reservation. It was carried westward by Indian telegraphy which none of us fully understands, except that it seems to be through signal fires from elevated positions. But in that case, there must have been smoke or blaze visible at different points, as we know was really the case.

But Alden Payne saw only the shadowy wisp of vapor in front of him, and must wait to learn its full meaning. That knowledge could not be long in coming.
