There is a chain of Being of whose top alike and bottom we know nothing at all. What we do know is that our own is a link in it, and cannot generally, can only fitfully and rarely, have intercourse with any other. I am not prepared with any modern instances of intercourse with the animal and vegetable world, even to such a limited extent, for instance, as that of Balaam with his ass, or that of Achilles with his horses; but I suspect that there are an enormous number unrecorded. Speech, of course, is not necessary to such an intercourse. Speech is a vehicle of human intercourse, but not of that of any other created order so far as we know.[8] Birds and beasts do not converse in speech, smell or touch seems to be the sense employed; and though the vehicles of smell and touch are unknown to us, in moments of high emotion we ourselves converse otherwise than by speech. Indeed, seeing that all created things possess a spirit whereby they are what they are, it does not seem necessary to suppose intercourse impossible without speech, and I myself have never had any difficulty in accepting the stories of much more vital mixed intercourse which we read of in the Greek and other mythologies. If we read, for instance, that such and such a man or woman was the offspring of a woman and the spirit of a river, or of a man and the spirit of a hill or oak-tree, it does not seem to me at all extraordinary. The story of the wife who suffered a fairy union and bore a fairy child which disappeared with her is a case in point. The fairy father was, so far as I can make out, the indwelling spirit of a rose, and the story is too painful and the detail in my possession too exact for me to put it down here. I was myself actually present, and in the house, when the child was born. I witnessed the anguish of the unfortunate husband, who is now dead. Mr. Wentz has many instances of the kind from Ireland and other Celtic countries; but fairies are by no means confined to Celtic countries, though they are more easily discerned by Celtic races. [Footnote 8: The speech of Balaam's ass or of Balaam, of Achilles and his horses are, of course, necessary conventions of the poet's and do not imply that words passed between the parties.]
