And then I remembered the crazy theories of a pupil of mine at St Chad's, the son of a small landowner on the Aller, a young gentleman who had spent his substance too freely at Oxford, and was now dreeing his weird in the Backwoods. He had been no scholar but a certain imagination marked all his doings, and of a Sunday night he would come and talk to me of the North. The Picts were his special subject, and his ideas were mad. "Listen to me," he would say, when I had mixed him toddy and given him one of my cigars; "I believe there are traces--ay, and more than traces--of an old culture lurking in those hills and waiting to be discovered. We never hear of the Picts being driven from the hills. The Britons drove them from the lowlands, the Gaels from Ireland did the same for the Britons; but the hills were left unmolested. We hear of no one going near them except outlaws and tinklers. And in that very place you have the strangest mythology. Take the story of the Brownie. What is that but the story of a little swart man of uncommon strength and cleverness, who does good and ill indiscriminately, and then disappears? There are many scholars, as you yourself confess, who think that the origin of the Brownie was in some mad belief in the old race of the Picts, which still survived somewhere in the hills. And do we not hear of the Brownie in authentic records right down to the year 1756? After that, when people grew more incredulous, it is natural that the belief should have begun to die out; but I do not see why stray traces should not have survived till late." "Do you not see what that means?" I had said in mock gravity. "Those same hills are, if anything, less known now than they were a hundred years ago. Why should not your Picts or Brownies be living to this day?" "Why not, indeed?" he had rejoined, in all seriousness.
