And so fixed was my mind upon travelling that I wrote to several of my friends, and told them of my intention. But I need scarcely say that as I urged them to keep the matter secret it was talked about far and wide. Indeed, as I afterwards found to my cost, there were paragraphs in the newspapers stating that the eccentric amateur painter and heir of one branch of the Aylwins had at last gone to Japan, and that as his deep interest in a certain charming beauty of an un-English type was proverbial, it was expected that he would return with a Japanese, or perhaps a Chinese wife. But I did not go to Japan; and what prevented me? My reason told me that what I had just seen near Beddgelert was an optical illusion. I had become very learned on the subject of optical illusions ever since I had known Sinfi Lovell, and especially since I had seen that picture of Winnie in the water near Bettws y Coed, which I have described in an earlier chapter. Every book I could get upon optical illusions I had read, and I was astonished to find how many instances are on record of illusions of a much more powerful kind than mine. And yet I could not leave Snowdon. The mountain's very breath grew sweeter and sweeter of Winnie's lips. As I walked about the hills I found myself repeating over and over again one of the verses which Winnie used to sing to me as a child at Raxton. Eryri fynyddig i mi, Bro dawel y delyn yw, Lle mae'r defaid a'r wyn, Yn y mwswg a'r brwyn, Am cân inau'n esgyn i fyny, A'r gareg yn ateb i fyny, i fyny, O'r lle bu'r eryrod yn byw. [Footnote] [Footnote: Mountain-wild Snowdon for me! Sweet silence there for the harp, Where loiter the ewes and the lambs, In the moss and the rushes, Where one's song goes sounding up And the rocks re-echo it higher and higher In the height where the eagles live.] But then I felt that Sinfi was the mere instrument of the mysterious magic of y Wyddfa, that magic which no other mountain in Europe exercises. I knew that among all the Gypsies Sinfi was almost the only one who possessed that power which belonged once to her race, that power which is expressed in a Scottish word now universally misused, 'glamour,' the power which Johnnie Faa and his people brought into play when they abducted Lady Casilis. Soon as they saw her well-faured face They cast the glamour oure her. 'Yes,' I said, 'I am convinced that my illusion is the result of two causes, my own brooding over Winnie's tragedy and the glamour that Sinfi sheds around her, either consciously or unconsciously; that imperious imagination of hers which projects her own visions upon the senses of another person either with or without an exercise of her own will. This is the explanation, I am convinced.'
