It was possible that Mink Havers had reached down from the surface and slipped his treasure in somewhere. And it was more than probable that his partner had searched that area, as also the area near the bottom. But was it not possible that Havers had descended part way, secreted his treasure behind some loose stone, and then climbed out? If he had, it seemed likely that there was still an uninspected belt in that crude masonry. Brent believed (so he said) that the accumulation of débris in the bottom raised the floor of the well to a point enabling him to explore this area. It was good reasoning and showed his real intelligence.

He had not scrutinized the wall for long, nor removed many suspicious stones, before he noticed something which gave him a thrill. This was a stone with a rough cross cut upon it. And you will understand that this was at a point in the well which must have been several feet above the head even of Long Buck as he stood on the bottom many years before. You will remember, too, that the old hunter had no glaring flashlight to aid him in his search.

With these thoughts in his mind it was with a thrill that Brent’s eye fell upon this rough cross cut in a stone of the masonry. With his jackknife he began digging at the plaster around it and his hope ran high as he found that it crumbled readily. He thought that clay might hastily have been introduced there in place of the dislodged plaster.

At last with trembling hands he got a hold upon the stone and worked it out. I can well imagine his excitement (young philosopher though he is) as he removed this stone with its telltale mark. He had to reach somewhat above him to do this and had slipped his flashlight under his armpit to use both hands, when suddenly the flashlight slipped from its place and fell upon the enmeshed and rotted accumulation on which he had been keeping a precarious foothold. Instantly there was an appalling rattling sound (emphasized, I suppose, by that dark echoing shaft) and Brent’s blood ran cold as he beheld almost at his very feet a coiled snake hissing with darting tongue at the area of brightness shed by the flashlight.

Brent still held the stone in air and his thoughts of hidden treasure vanished at the horrible spectacle below him. Should he drop the stone upon the enraged reptile? Suppose it should not fall right? And how long would this frightful thing, hated by man and bird and beast—how long would it wait?

It was angry at the flashlight, not at Brent. But if Brent moved, stirred ... And, meanwhile, the seconds passed. A crumbling bit of plaster fell. The hissing continued. The little ball of light burned brightly and cast a luminous circle on the dank, oppressive débris. Six, seven, eight seconds. And Brent Gaylong did not stir—not a hair. He stood like a statue. But his blood was cold. Nine, ten, eleven seconds.

We are all subject to insane impulses. Who has not felt the impulse to jump off a roof? For a moment Brent was in the spell of a strange impulse to stoop leisurely, lay down the stone and pick up his flashlight. But he did not do that. He did not budge. He still held the stone above his head, like a piece of Roman statuary. The reptile did not budge either, but he rattled and hissed, and his tongue darted like lightning. And meanwhile the seconds passed—twelve, thirteen, fourteen....

CHAPTER XV—The Trap

Now something happened, trivial and barely perceptible, but it relieved the frightful situation of the moment. The flashlight flickered; it was less than a flicker; a scarcely visible flutter of the light for the fraction of a second. But the alert reptile projected its head like lightning. Its appalling rattle sounded in the hollow shaft; it hissed and its tongue darted.

Brent Gaylong knew what that suggestion of a flicker meant; he had tinkered often enough with the defective connection in that troublesome flashlight. Should he cast the stone down on the horrible thing’s head? Suppose he should miss? Again the light flickered. Fortunately, that hideous, flat head was in the circle of brightness cast by the flashlight. It was poised menacingly a few inches above a flat bit of rock.
