Presently we began again to get a little strength; and as the soldiers were now lying closer along the river-side, Alan proposed that we should try a start. I was by this time afraid of but one thing in the world; and that was to be set back upon the rock; anything else was welcome to me; so we got ourselves at once in marching order, and began to slip from rock to rock one after the other, now crawling flat on our bellies in the shade, now making a run for it, heart in mouth. The soldiers, having searched this side of the valley after a fashion, and being perhaps somewhat sleepy with the sultriness of the afternoon, had now laid by much of their vigilance, and stood dozing at their posts or only kept a look-out along the banks of the river; so that in this way, keeping down the valley and at the same time towards the mountains, we drew steadily away from their neighbourhood. But the business was the most wearing I had ever taken part in. A man had need of a hundred eyes in every part of him, to keep concealed in that uneven country and within cry of so many and scattered sentries. When we must pass an open place, quickness was not all, but a swift judgment not only of the lie of the whole country, but of the solidity of every stone on which we must set foot; for the afternoon was now fallen so breathless that the rolling of a pebble sounded abroad like a pistol shot, and would start the echo calling among the hills and cliffs. By sundown we had made some distance, even by our slow rate of progress, though to be sure the sentry on the rock was still plainly in our view. But now we came on something that put all fears out of season; and that was a deep rushing burn, that tore down, in that part, to join the glen river. At the sight of this we cast ourselves on the ground and plunged head and shoulders in the water; and I cannot tell which was the more pleasant, the great shock as the cool stream went over us, or the greed with which we drank of it. We lay there (for the banks hid us), drank again and again, bathed our chests, let our wrists trail in the running water till they ached with the chill; and at last, being wonderfully renewed, we got out the meal-bag and made drammach in the iron pan. This, though it is but cold water mingled with oatmeal, yet makes a good enough dish for a hungry man; and where there are no means of making fire, or (as in our case) good reason for not making one, it is the chief stand-by of those who have taken to the heather.
