Curiosity took Adam Salton out of bed in the early morning, but when he had dressed and gone downstairs; he found that, early as he was, Sir Nathaniel was ahead of him. The old gentleman was quite prepared for a long walk, and they started at once.

Sir Nathaniel, without speaking, led the way to the east, down the hill. When they had descended and risen again, they found themselves on the eastern brink of a steep hill. It was of lesser height than that on which the Castle was situated; but it was so placed that it commanded the various hills that crowned the ridge.

All along the ridge the rock cropped out, bare and bleak, but broken in rough natural castellation. The form of the ridge was a segment of a circle, with the higher points inland to the west. In the centre rose the Castle, on the highest point of all. Between the various rocky excrescences were groups of trees of various sizes and heights, amongst some of which were what, in the early morning light, looked like ruins. These--whatever they were--were of massive grey stone, probably limestone rudely cut--if indeed they were not shaped naturally. The fall of the ground was steep all along the ridge, so steep that here and there both trees and rocks and buildings seemed to overhang the plain far below, through which ran many streams.

Sir Nathaniel stopped and looked around, as though to lose nothing of the effect. The sun had climbed the eastern sky and was making all details clear. He pointed with a sweeping gesture, as though calling Adam's attention to the extent of the view. Having done so, he covered the ground more slowly, as though inviting attention to detail. Adam was a willing and attentive pupil, and followed his motions exactly, missing--or trying to miss--nothing.

"I have brought you here, Adam, because it seems to me that this is the spot on which to begin our investigations. You have now in front of you almost the whole of the ancient kingdom of Mercia. In fact, we see the whole of it except that furthest part, which is covered by the Welsh Marches and those parts which are hidden from where we stand by the high ground of the immediate west. We can see--theoretically--the whole of the eastern bound of the kingdom, which ran south from the Humber to the Wash. I want you to bear in mind the trend of the ground, for some time, sooner or later, we shall do well to have it in our mind's eye when we are considering the ancient traditions and superstitions, and are trying to find the RATIONALE of them. Each legend, each superstition which we receive, will help in the understanding and possible elucidation of the others. And as all such have a local basis, we can come closer to the truth--or the probability--by knowing the local conditions as we go along. It will help us to bring to our aid such geological truth as we may have between us. For instance, the building materials used in various ages can afford their own lessons to understanding eyes. The very heights and shapes and materials of these hills--nay, even of the wide plain that lies between us and the sea--have in themselves the materials of enlightening books.""For instance, sir?" said Adam, venturing a question.

"Well, look at those hills which surround the main one where the site for the Castle was wisely chosen--on the highest ground. Take the others. There is something ostensible in each of them, and in all probability something unseen and unproved, but to be imagined, also.""For instance?" continued Adam.

"Let us take them SERIATIM. That to the east, where the trees are, lower down--that was once the location of a Roman temple, possibly founded on a pre-existing Druidical one. Its name implies the former, and the grove of ancient oaks suggests the latter.""Please explain."
