“On my second visit to the chapel,” he went on, “my purpose was to take every note I could of figures, lettering, diamond-scratchings on the glass, and even apparently accidental markings. The first point which I tackled was that of the inscribed scrolls. I could not doubt that the first of these, that of Job—‘There is a place for the gold where it is hidden’—with its intentional alteration, must refer to the treasure; so I applied myself with some confidence to the next, that of St John—‘They have on their vestures a writing which no man knoweth.’ The natural question will have occurred to you: Was there an inscription on the robes of the figures? I could see none; each of the three had a broad black border to his mantle, which made a conspicuous and rather ugly feature in the window. I was nonplussed, I will own, and, but for a curious bit of luck, I think I should have left the search where the Canons of Steinfeld had left it before me. But it so happened that there was a good deal of dust on the surface of the glass, and Lord D——, happening to come in, noticed my blackened hands, and kindly insisted on sending for a Turk’s head broom to clean down the window. There must, I suppose, have been a rough piece in the broom; anyhow, as it passed over the border of one of the mantles, I noticed that it left a long scratch, and that some yellow stain instantly showed up. I asked the man to stop his work for a moment, and ran up the ladder to examine the place. The yellow stain was there, sure enough, and what had come away was a thick black pigment, which had evidently been laid on with the brush after the glass had been burnt, and could therefore be easily scraped off without doing any harm. I scraped, accordingly, and you will hardly believe—no, I do you an injustice; you will have guessed already—that I found under this black pigment two or three clearly-formed capital letters in yellow stain on a clear ground. Of course, I could hardly contain my delight. “I told Lord D—— that I had detected an inscription which I thought might be very interesting, and begged to be allowed to uncover the whole of it. He made no difficulty about it whatever, told me to do exactly as I pleased, and then, having an engagement, was obliged—rather to my relief, I must say—to leave me. I set to work at once, and found the task a fairly easy one. The pigment, disintegrated, of course, by time, came off almost at a touch, and I don’t think that it took me a couple of hours, all told, to clean the whole of the black borders in all three lights. Each of the figures had, as the inscription said, ‘a writing on their vestures which nobody knew’.
