had taken the thing off to the hospital hidden in the dog-fish sack, and there had pressed the young investigator to keep it for him. Mr. Wace was a little dubious at first. His relationship to Cave was peculiar. He had a taste for singular characters, and he had more than once invited the old man to smoke and drink in his rooms, and to unfold his rather amusing views of life in general and of his wife in particular. Mr. Wace had encountered Mrs. Cave, too, on occasions when Mr. Cave was not at home to attend to him. He knew the constant interference to which Cave was subjected, and having weighed the story judicially, he decided to give the crystal a refuge. Mr. Cave promised to explain the reasons for his remarkable affection for the crystal more fully on a later occasion, but he spoke distinctly of seeing visions therein. He called on Mr. Wace the same evening.
He told a complicated story. The crystal he said had come into his possession with other oddments at the forced sale of another curiosity dealer's effects, and not knowing what its value might be, he had ticketed it at ten shillings. It had hung upon his hands at that price for some months, and he was thinking of "reducing the figure," when he made a singular discovery.
At that time his health was very bad—and it must be borne in mind that, throughout all this experience, his physical condition was one of ebb—and he was in considerable distress by reason of the negligence, the positive ill-treatment even, he received from his wife and step-children. His wife was vain, extravagant, unfeeling, and had a growing taste for private drinking; his step-daughter was mean and over-reaching; and his step-son had conceived a violent dislike for him, and lost no opportunity of showing it. The requirements of his business pressed heavily upon him, and Mr. Wace does not think that he was altogether free from occasional intemperance. He had begun life in a comfortable position, he was a man of fair education, and he suffered, for weeks at a stretch, from melancholia and insomnia. Afraid to disturb his family, he would slip quietly from his wife's side, when his thoughts became intolerable, and wander about the house. And about three o'clock one morning, late in August, chance directed him into the shop.
The dirty little place was impenetrably black except in one spot, where he perceived an unusual glow of light. Approaching this, he discovered it to be the crystal egg, which was standing on the corner of the counter towards the window. A thin ray shot through a crack in the shutters, impinged upon the object, and seemed as it were to fill its entire interior.
It occurred to Mr. Cave that this was not in accordance with the laws of optics as he had known them in his younger days. He could understand the rays being reflected by the crystal and coming to a focus in its interior, but this diffusion jarred with his physical conceptions. He approached the crystal more nearly, peering into it and around it, with a transient revival of the scientific curiosity that in his youth had determined his choice of a calling. He was surprised to find the light not steady, but writhing within the substance of the egg, as though that object was a hollow sphere of some luminous vapor. In moving about to get different points of view, he suddenly found that he had come between it and the ray, and that the crystal none the less remained luminous. Greatly astonished, he lifted it out of the light ray and carried it to the darkest part of the shop. It remained bright for some four or five minutes, then it slowly faded and went out. He placed it in the thin streak of daylight, and its luminousness was almost immediately restored.
So far, at least, Mr. Wace was able to verify the remarkable story of Mr. Cave. He had himself repeatedly held this crystal in a ray of light (which had to be of a smaller diameter than one millimetre). And in a perfect darkness, such as could be produced by velvet wrapping, the crystal did undoubtedly appear very faintly phosphorescent. It would seem, however, that the luminousness was of some exceptional sort, and not equally visible to all eyes; for Mr. Harbinger—whose name will be familiar to the scientific reader in connection with the Pasteur Institute—was quite unable to see any light whatever. And Mr. Wace's own capacity for its appreciation was out of comparison inferior to that of Mr. Cave's. Even with Mr. Cave the power varied very considerably; his vision was most vivid during states of extreme weakness and fatigue.
Now, from the outset this light in the crystal exercised a curious fascination upon Mr. Cave. And it says more for his loneliness of soul than a volume of pathetic writing could do, that he told no human being of his curious 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.
But the use of an old velvet cloth, which he used as a background for a collection of minerals, occurred to him, and by doubling this, and putting it over his head and hands, he was able to get a slight luminous movement within the crystal even in the day-time. 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 things, and, according as the direction of the lighting and vision changed, the picture changed also. It must, indeed, have been like looking through
