I know a gentleman belonging to one of the learned professions whose career as, let us say, a surgeon would not be helped if this article were to connect him with fairy lore. As a matter of fact, in spite of his solemn avocations and his practical and virile character, he seems to be endowed with that faculty — let us call it the appreciation of higher vibrations — which opens up so wonderful a door to its possessor. He claims, or rather he admits, for he is reticent upon the subject, that he has carried this power of perception on from childhood, and his surprise is not so much at what he sees as at the failure of others to see the same thing. To show that it is not subjective, he tells the story that on one occasion, while traversing a field, he saw a little creature which beck- oned eagerly that he should follow. He did so, and presently saw his guide pointing with an air of importance to the ground. There, between the furrows, lay a flint arrow-head which he carried home with him as a souvenir of the adventure. (Doyle, Coming of the Fairies 135-136)
