How does Paul Scott use imagery in The Jewel in the Crown?

Imagery:

"When I looked out on to the maidan from the window of my room in the old artillery mess in Mayapore, or drove round the cantonment, I could not help but feel proud of the years of British rule. Even in these turbulent times the charm of the cantonment helped one to bear in mind the calm, wise and enduring things."

"It was on the stone steps leading to the verandah that the girl stumbled at the end of her headlong flight in the dark from the Bibighar Gardens; stumbled, fell, and crawled on her hands and knees the rest of the way to safety and into the history of a troubled period."
