I am not a believer in ghosts in general; I see no good in them. They come—that is, are reported to come—so irrelevantly, purposelessly—so ridiculously, in short—that one's common sense as regards this world, one's supernatural sense of the other, are alike revolted. Then nine out of ten 'capital ghost stories' are so easily accounted for; and in the tenth, when all natural explanation fails, one who has discovered the extraordinary difficulty there is in all society in getting hold of that very slippery article called a fact, is strongly inclined to shake a dubious head, ejaculating, 'Evidence! it is all a question of evidence!'
