I was very quiet for a while, watching dreamily the dark shadows of the dusk.

Hist! What was that? Surely the bushes were moving over there by the hillside. I strained my eyes. I was right: they were.

I was all nerves and excitement now, my heart beating wildly, my eyes boring through the gloom. Very softly I put out my hand and grasped the shot-gun.

I watched and waited. A man was parting the bushes. Stealthily, very stealthily, he peered around. He hesitated, paused, peered again, crouched on all-fours, crept forward a little. Everything was quiet as a grave. Down in the cabins the tired men slept peacefully; stillness and solitude.

Cautiously the man, crawling like a snake, worked his way to the sluice-boxes. None but a keen watcher could have seen him. Again and again he paused, peered around, listened intently. Very carefully, with my eyes fixed on him, I lifted the gun.

Now he had gained the shadow of the nearest sluice-box. He clung to the trestle-work, clung so closely you could scarce tell him apart from it. He was like a rat, dark, furtive, sinister. Slowly I lifted the gun to my shoulder. I had him covered.

I waited. Somehow I was loath to shoot. My nerves were a-quiver. Proof, more proof, I said. I saw him working busily, lying flat alongside the boxes. How crafty, how skilful he was! He was disconnecting the boxes. He would let the water run to the ground; then, there in the exposed riffles, would be his harvest. Would I shoot ... now ... now....

Then, in the midnight hush, my gun blazed forth. With one scream the man tumbled down, carrying along with him the disconnected box. The water rushed over the ground in a deluge. I must capture him. There he lay in that pouring stream.... Now I had him.

In that torrent of icy water I grappled with my man. Over and over we rolled. He tried to gouge me. He was small, but oh, how strong! He held down his face. Fiercely I wrenched it up to the light. Heavens! it was the Worm.

I gave a cry of surprise, and my clutch on him must have weakened, for at that moment he gave a violent wrench, a cat-like twist, and tore himself free. Men were coming, were shouting, were running in from all directions.
