The light from the urns was but faint, and it was not easy to distinguish their black heads against the black water; still, I could see their approach. Two of them held spears in their hands; I saw the copper heads flash on high.

I stood at the edge of the lake, wondering at their folly as I waited; they were now scarcely ten feet away. Another few strokes and the foremost stretched out his hand to grasp the slippery ledge; my spear came down crushingly on his head and he fell back into the water.

By that time another had crawled half onto the ledge, and another; a blow and a quick thrust, and they, too, slipped back beneath the surface, pawing in agony, not to rise again.

Just in time I saw that one of the remaining three had lifted himself in the water not five feet away, with his spear aimed at my breast. But the poor devil had no purchase for his feet and the thing went wide.

The next instant he had received a ten-pound stone full in the face and went down with a gurgle. At that the remaining two, seeming to acquire a glimmering of intelligence, turned and swam hastily away. I let them go.

Turning to Harry, I saw that the crevice also was clear. He had left his post and started toward me, but I waved him back.

"All right here, Hal: have they given it up?"

There was an expression of the most profound disgust on his face.

"Paul, it's rank butchery. I'm wading in blood. Will this thing never stop?"

I looked at him and said merely: "Yes."
