While he looked there came to his ears a roaring, as of some high-powered car traveling under full pressure of gas.

The burros followed him, but William lifted his head and brayed tremulously three times in the dark.

Casey had never heard him bray before, and the sudden rasping outcry startled him.
He went back and stood for a minute looking at William, who turned tail and started back toward the shore they had left behind them.

Casey ran to head him off, yelling threats, and William, in spite of his six water cans--two of them empty--broke into a lope.
