I begged to trail with him an old track over the prairie, in order to learn its history.

I had hardly made the proposition, when he drew up his horse, which was at a ravine, and said, 'Well, here is an old elk track.

Let us get off our horses and follow it.' We followed it but a few rods, when he said, it was exactly a month old, and made at 2 o'clock in the afternoon.

This he knew, as then we had our last rain, and at the hour named the ground was softer than at any other time.

The track before us was then made.
