There is no twilight to speak of in the tropics, and the sunset glow was fading rapidly, but there was still light enough to show the place in the pit bottom where the bits of black humus were thickest. At sight of them I became, in my turn, a foolish madman, postulating a frantic gopher with a time limit set in which he may hope to outdig the scratching dogs in his burrow. But there was at least a saving grain of method in my madness. Every fresh stab of the knife brought up more of the rotted wood, and presently the blade struck something hard and unyielding.
"Hold your breath, you two," I gasped, and groping hastily in the loosened sand with my hands I found the hard thing that the knife blade had struck; found and unearthed it and straightened up to lay it at Madeleine's feet.
It was a rudely cast ingot of dull-colored metal, and its weight, in proportion to its size, was sufficient proof of its quality. It was unmistakably a billet of gold.

FINDERS KEEPERS
For the next few minutes after the discovery of the bar of gold I think no one of the three of us was wholly sane. Van Dyck and I fell over each other in our eagerness to find out if there were more of them, and as we dug deep in the treasure grave Madeleine knelt at the edge of it and was to the full as daft as either of us.
Digging and groping by turns, we flung out bar after bar of the precious metal until there was a heap of forty of them piled up in the little glade. Forty was the exact number. When it was complete we found that we had penetrated to the under-layer of humus which told us that we had come to the rotted bottom of the chest in which the treasure had been buried.
I think Madeleine was the first to break the spell of breathless silence that had fallen upon us while we were digging and dog-scratching in the soft sand.
"It can't be true! I can't believe it!" she said, over and over again. "We are dreaming; we must be dreaming—all of us!"
