How does John Dos Passos use imagery in Manhattan Transfer?

Example of Imagery:

"With a long slow stride, limping a little from his blistered feet, Bud walked down Broadway, past empty lots where tin cans glittered among grass and sumach bushes and ragweed, between ranks of billboards and Bull Durham signs, past shanties and abandoned squatters' shacks, past gulches heaped with wheelscarred rubbishpiles where dumpcarts were dumping ashes and clinkers, past knobs of gray outcrop where steamdrills continually tapped and nibbled, past excavations out of which wagons full of rock and clay toiled up plank roads to the street, until he was walking on new sidewalks along a row of yellow brick apartment houses, looking in the windows of grocery stores, Chinese laundries, lunchrooms, flower and vegetable shops, tailors', delicatessens."
