was standing, and I felt uncommonly pleased that I was in hiding. I couldn't make out much feature, but I saw his eyes gleaming and his teeth showing, and he had an ugly-looking knife in one hand, and I thought things would be very unpleasant for gentleman number one if the second robber, or robbed, or what you like, caught him up. I can tell you, Phillipps, a fox hunt is exciting enough, when the horn blows clear on a winter morning, and the hounds give tongue, and the red-coats charge away, but it's nothing to a man hunt, and that's what I had a slight glimpse of to-night. There was murder in the fellow's eyes as he went by, and I don't think there was much more than fifty seconds between the two. I only hope it was enough." Dyson leant back in his armchair and relit his pipe, and puffed thoughtfully. Phillipps began to walk up and down the room, musing over the story of violent death fleeting in chase along the pavement, the knife shining in the lamplight, the fury of the pursuer, and the terror of the pursued. "Well," he said at last, "and what was it, after all, that you rescued from the gutter?" Dyson jumped up, evidently quite startled. "I really haven't a notion. I didn't think of looking. But we shall see." He fumbled in his waistcoat pocket and drew out a small and shining object, and laid it on the table. It glowed there beneath the lamp with the radiant glory of rare old gold; and the image and the letters stood out in high relief, clear and sharp, as if it had but left the mint a month before. The two men bent over it, and Phillipps took it up and examined it closely. "Imp. Tiberius Cæsar Augustus," he read the legend, and then, looking at the reverse of the coin, he stared in amazement, and at last turned to Dyson with a look of exultation. "Do you know what you have found?" he said. "Apparently a gold coin of some antiquity," said Dyson, coolly. "Quite so, a gold Tiberius. No, that is wrong. You have found _the_ gold Tiberius. Look at the reverse." Dyson looked and saw the coin was stamped with the figure of a faun standing amidst reeds and flowing water. The features, minute as they were, stood out in delicate outline; it was a face lovely and yet terrible, and Dyson thought of the well-known passage of the lad's playmate, gradually growing with his growth and increasing with his stature, till the air was filled with the rank fume of the goat. "Yes," he said, "it is a curious coin. Do you know it?"
