Yet when we think how narrow and how devious this path of Nature is, how dimly we can trace it, for all our lamps of science, and how from the darkness which girds it round great and terrible possibilities loom ever shadowly upwards, it is a bold and confident man who will put a limit to the strange by- paths into which the human spirit may wander.

In a certain wing of what we will call Old College in Oxford there is a corner turret of an exceeding great age. The heavy arch which spans the open door has bent downwards in the centre under the weight of its years, and the grey, lichen-blotched blocks of stone are, bound and knitted together with withes and strands of ivy, as though the old mother had set herself to brace them up against wind and weather. From the door a stone stair curves upward spirally, passing two landings, and terminating in a third one, its steps all shapeless and hollowed by the tread of so many generations of the seekers after knowledge. Life has flowed like water down this winding stair, and, waterlike, has left these smooth- worn grooves behind it. From the long-gowned, pedantic scholars of Plantagenet days down to the young bloods of a later age, how full and strong had been that tide of young English life. And what was left now of all those hopes, those strivings, those fiery energies, save here and there in some old-world churchyard a few scratches upon a stone, and perchance a handful of dust in a mouldering coffin? Yet here were the silent stair and the grey old wall, with bend and saltire and many another heraldic device still to be read upon its surface, like grotesque shadows thrown back from the days that had passed.

In the month of May, in the year 1884, three young men occupied the sets of rooms which opened on to the separate landings of the old stair. Each set consisted simply of a sitting-room and of a bedroom, while the two corresponding rooms upon the ground- floor were used, the one as a coal-cellar, and the other as the living-room of the servant, or gyp, Thomas Styles, whose duty it was to wait upon the three men above him. To right and to left was a line of lecture-rooms and of offices, so that the dwellers in the old turret enjoyed a certain seclusion, which made the chambers popular among the more studious undergraduates. Such were the three who occupied them now--Abercrombie Smith above, Edward Bellingham beneath him, and William Monkhouse Lee upon the lowest storey.

It was ten o'clock on a bright spring night, and Abercrombie Smith lay back in his arm-chair, his feet upon the fender, and his briar-root pipe between his lips. In a similar chair, and equally at his ease, there lounged on the other side of the fireplace his old school friend Jephro Hastie. Both men were in flannels, for they had spent their evening upon the river, but apart from their dress no one could look at their hard-cut, alert faces without seeing that they were open-air men--men whose minds and tastes turned naturally to all that was manly and robust. Hastie, indeed, was stroke of his college boat, and Smith was an even better oar, but a coming examination had already cast its shadow over him and held him to his work, save for the few hours a week which health demanded. A litter of medical books upon the table, with scattered bones, models and anatomical plates, pointed to the extent as well as the nature of his studies, while a couple of single- sticks and a set of boxing-gloves above the mantelpiece hinted at the means by which, with Hastie's help, he might take his exercise in its most compressed and least distant form. They knew each other very well--so well that they could sit now in that soothing silence which is the very highest development of companionship.

"Have some whisky," said Abercrombie Smith at last between two cloudbursts. "Scotch in the jug and Irish in the bottle."

"No, thanks. I'm in for the sculls. I don't liquor when I'm training. How about you?"

"I'm reading hard. I think it best to leave it alone."

Hastie nodded, and they relapsed into a contented silence.

"By-the-way, Smith," asked Hastie, presently, have you made the acquaintance of either of the fellows on your stair yet?"

"Just a nod when we pass. Nothing more."

"Hum! I should be inclined to let it stand at that. I know something of them both. Not much, but as much as I want. I don't think I should take them to my bosom if I were you. Not that there's much amiss with Monkhouse Lee."

"Meaning the thin one?"

"Precisely. He is a gentlemanly little fellow. I don't think there is any vice in him. But then you can't know him without knowing Bellingham."

"Meaning the fat one?"

"Yes, the fat one. And he's a man whom I, for one, would rather not know."

Abercrombie Smith raised his eyebrows and glanced across at his companion.

"What's up, then?" he asked. "Drink? Cards? Cad? You used not to be censorious."

"Ah! you evidently don't know the man, or you wouldn't ask. There's something damnable about him-- something reptilian.
