Read the following excerpt from "A Sunrise on the Veld."
"And for minutes he stood there, shouting and singing and waiting for the lovely eddying sound of the echo; so that his own new strong thoughts came back and washed round his head, as if someone were answering him and encouraging him; till the gorge was full of soft voices clashing back and forth from rock to rock over the river. And then it seemed as if there was a new voice. He listened, puzzled, for it was not his own. Soon he was leaning forward, all his nerves alert, quite still: somewhere close to him there was a noise that was no joyful bird, nor tinkle of falling water, nor ponderous movement of cattle."
