"They have had a good many days' start of you," observed Bartle, "and if they have kept on going, they must be some distance on their road by this time." "Then we must push on all the faster," said the lieutenant. "I should like to catch the fellows before the Indians take their scalps; although, when we have got them, it will be difficult to know what to do with them, as they will delay me while they move slowly along on foot." "Send them back to us; we will soon show them how to use their picks and spades," said Bartle. After the usual hand-shaking at parting, and the lieutenant had once more lifted his cap to Clarice, who stood at the door watching us, we set off down the hill, each of us leading a baggage-mule by the bridle. Every inch of the way, for some miles, was known to me, so that we could move on without troubling ourselves about the road. We had occasionally hills to go over, spurs of the big mountains on our left; but we kept as much we could on the level ground,--sometimes having to make a detour for the sake of avoiding the rocky heights, which were inaccessible to our animals. As the day advanced we began to look out for the runaways, although the lieutenant was of opinion that they must be still some way ahead of us. We also kept our eyes open on the chance of any Indians coming down upon us,--although I did not think that there was much risk of that; for every one at the farm had been convinced that the Arrapahas had long since gone away to the southward, and that we should hear no more of them. That night we encamped at a snug spot near a stream, with a wood to the southward almost surrounding us, so that the light of our fire could not be seen by any one on that side. There was rich grass for our animals, and they were therefore not likely to stray. We were both young, in good health and spirits, and with no cares to oppress us, so we greatly enjoyed our bivouac. We sat by the fire chatting away for some time; then we lay down, wrapped in our buffalo robes, to sleep, resolving to awake at intervals, in order to put on fresh fuel, as it was important not to let our fire get low. Fortunately, we awoke as often as was needful, and by maintaining a good blaze we kept at a distance any bears or wolves which might have been prowling about. The next morning, at daybreak, we once more moved on. As yet, we had discovered no signs of the runaways; indeed, when we came to think over the matter, we considered that they would probably have kept out of the beaten track, in order to avoid discovery should they be pursued. From the nature of the ground, they would not have gone to the left; and I therefore suggested that we should keep to the right, where, if they really were making for the pass, we should be pretty certain of coming upon them. We accordingly struck off at an angle in the direction I proposed, and then once more continued our former course northward, keeping a bright look-out ahead and on either side.
