Careless of danger, the boys dropped to the ground and, spears in hand,
ran like deer toward the scene of their weeks of labor. Side by side they
bounded to the edge of the excavation, which now yawned open to the sky.
They had triumphed at last! As they saw what the pitfall held, they
yelled in unison, and danced wildly around the opening, in the very
height of boyish triumph. The exultation was fully justified, for the
pitfall held a young rhinoceros, a creature only a few months old, but so
huge already that it nearly filled the excavation. It was utterly
helpless in the position it occupied. It was wedged in, incapable of
moving more than slightly in any direction. Its long snout, with its
sprouting pair of horns, was almost level with the surface of the ground
and its small bright eyes leered wickedly at its noisy enemies. It
struggled clumsily upon their approach, but nothing could relieve the
hopelessness of its plight.

All about the pitfall the earth was plowed in furrows and beaten down by
the feet of some monstrous animal. Evidently the calf was in the company
of its mother when it fell a victim to the art of the pitfall diggers. It
was plain that the mother had spent most of the night about her young in
a vain effort to release it. Well did the cave boys understand the signs,
and, after their first wild outburst of joy over the capture, a sense of
the delicacy, not to say danger, of their situation came upon them. It
was not well to interfere with the family affairs of the rhinoceros.
Where had the mother gone? They looked about, but could see nothing to
justify their fears. Only for a moment, though, did their sense of safety
last; hardly had the echo of their shouting come back from the hillside
than there was a splashing and rasping of bushes in the swamp and the
rush of some huge animal toward the little ascent leading to the valley
proper. There needed no word from either boy; the frightened couple
bounded to the tree of refuge and had barely begun clambering up its
