observations. He seems to have been living in such an atmosphere of petty spite that to admit the existence of a pleasure would have been to risk the loss of it. He found that as the dawn advanced, and the amount of diffused light increased, the crystal became to all appearance non-luminous. And for some time he was unable to see anything in it, except at night-time, in dark corners of the shop.

He was very cautious lest he should be thus discovered by his wife, and he practised this occupation only in the afternoons, while she was asleep upstairs, and then circumspectly in a hollow under the counter. And one day, turning the crystal about in his hands, he saw something. It came and went like a flash, but it gave him the impression that the object had for a moment opened to him the view of a wide and spacious and strange country; and turning it about, he did, just as the light faded, see the same vision again.
Now it would be tedious and unnecessary to state all the phases of Mr. Cave's discovery from this point. Suffice that the effect was this: the crystal, being peered into at an angle of about 137 degrees from the direction of the illuminating ray, gave a clear and consistent picture of a wide and peculiar country-side. It was not dream-like at all: it produced a definite impression of reality, and the better the light the more real and solid it seemed. It was a moving picture: that is to say, certain objects moved in it, but slowly in an orderly manner like real
