Other waters yet there were: here and there from the hills on both sides, but especially from the south side, came trickles of water that ran in pretty brooks down to the river; and some of these sprang bubbling up amidst the foot-mounds of the sheer-rocks; some had cleft a rugged and strait way through them, and came tumbling down into the Dale at diverse heights from their faces. But on the north side about halfway down the Dale, one stream somewhat bigger than the others, and dealing with softer ground, had cleft for itself a wider way; and the folk had laboured this way wider yet, till they had made them a road running north along the west side of the stream. Sooth to say, except for the strait pass along the river at the eastern end, and the wider pass at the western, they had no other way (save one of which a word anon) out of the Dale but such as mountain goats and bold cragsmen might take; and even of these but few.
This midway stream was called the Wildlake, and the way along it Wildlake’s Way, because it came to them out of the wood, which on that north side stretched away from nigh to the lip of the valley-wall up to the pine woods and the high fells on the east and north, and down to the plain country on the west and south.
Now when the Weltering Water came out of the rocky tangle near the pass, it was turned aside by the ground till it swung right up to the feet of the Southern crags; then it turned and slowly bent round again northward, and at last fairly doubled back on itself before it turned again to run westward; so that when, after its second double, it had come to flowing softly westward under the northern crags, it had cast two thirds of a girdle round about a space of land a little below the grassy knolls and tofts aforesaid; and there in that fair space between the folds of the Weltering Water stood the Thorp whereof the tale hath told.
The men thereof had widened and deepened the Weltering Water about them, and had bridged it over to the plain meads; and athwart the throat of the space left clear by the water they had built them a strong wall though not very high, with a gate amidst and a tower on either side thereof. Moreover, on the face of the cliff which was but a stone’s throw from the gate they had made them stairs and ladders to go up by; and on a knoll nigh the brow had built a watch-tower of stone strong and great, lest war should come into the land from over the hills. That tower was ancient, and therefrom the Thorp had its name and the whole valley also; and it was called Burgstead in Burgdale.
