How does Evelyn Waugh use imagery in A Handful of Dust?

Imagery:

"They collected their wicker baskets and their rations of farine, their bows and arrows, the gun and their . . . knives; they rolled up their hammocks into compact cylinders. They took nothing with them that was not theirs. Then they crept back through the shadows, into the darkness."

"'she's lovely, he's rather a stick.'"
