The Wheels of Chance by H.G. Wells

Beyond Cobham came a delightful incident, delightful, that is, in its beginning if a trifle indeterminate in the retrospect. It was perhaps half-way between Cobham and Ripley. Mr. Hoopdriver dropped down a little hill, where, unfenced from the road, fine mossy trees and bracken lay on either side; and looking up he saw an open country before him, covered with heather and set with pines, and a yellow road running across it, and half a mile away perhaps, a little grey figure by the wayside waving something white. "Never! " said Mr. Hoopdriver with his hands tightening on the handles.

He resumed the treadles, staring away before him, jolted over a stone, wabbled, recovered, and began riding faster at once, with his eyes ahead. "It can't be," said Hoopdriver.
