Never in all his life did Bolo hear again such a terrific shriek as the falling mammoth gave. For many nights after that he covered his ears as he lay down to sleep so that he might not hear it again in his dreams. Then came the sickening crash as the gigantic body struck the rocks below. The men turned and fled, and the remaining mammoths, in a frenzy of fear, tore back down the landward side of the cliffs into the valley. For some moments the hunters, wide-eyed and breathless, watched the herd as it lumbered down the valley, until at last it passed behind the hills and was gone.
