account for his injuries.  On the other hand, a legend of a strange creature in the Gap has existed for some months back, and the farmers look upon Dr. Hardcastle’s narrative and his personal injuries as a final corroboration.  So the matter stands, and so the matter will continue to stand, for no definite solution seems to us to be now possible.  It transcends human wit to give any scientific explanation which could cover the alleged facts.”

Perhaps before the Courier published these words they would have been wise to send their representative to me.  I have thought the matter out, as no one else has occasion to do, and it is possible that I might have removed some of the more obvious difficulties of the narrative and brought it one degree nearer to scientific acceptance.  Let me then write down the only explanation which seems to me to elucidate what I know to my cost to have been a series of facts.  My theory may seem to be wildly improbable, but at least no one can venture to say that it is impossible.

My view is—­and it was formed, as is shown by my diary, before my personal adventure—­that in this part of England there is a vast subterranean lake or sea, which is fed by the great number of streams which pass down through the limestone.  Where there is a large collection of water there must also be some evaporation, mists or rain, and a possibility of vegetation.  This in turn suggests that there may be animal life, arising, as the vegetable life would also do, from those seeds and types which had been introduced at an early period of the world’s history, when communication with the outer air was more easy.  This place had then developed a fauna and flora of its own, including such monsters as the one which I had seen, which may well have been the old cave-bear, enormously enlarged and modified by its new environment.  For countless aeons the internal and the external creation had kept apart, growing steadily away from each other.  Then there had come some rift in the depths of the mountain which had enabled one creature to wander up and, by means of the Roman tunnel, to reach the open air.  Like all subterranean life, it had lost the power of sight, but this had no doubt been compensated for by nature in other directions.  Certainly it had some means of finding its way about, and of hunting down the sheep upon the hillside.  As to its choice of dark nights, it is part of my theory that light was painful to those great white eyeballs, and that it was only a pitch-black world which it could tolerate.  Perhaps, indeed, it was the glare of my lantern which saved my life at that awful moment when we were face to face.  So I read the riddle.  I leave these facts behind me, and if you can explain them, do so; or if you choose to doubt them, do so.  Neither your belief nor your incredulity can alter them, nor affect one whose task is nearly over.

So ended the strange narrative of Dr. James Hardcastle.
