question:  What is the purpose of the reclam crews?
context: Illustrated by DILLON HE was walking endlessly down a long, glass-walled corridor. Bright sunlight slanted in through one wall, on the blue knapsack across his shoulders. The corridor opened at last into a large high-domed room, much like a railway station or an air terminal. At the sight of him a man leaning negligently against a stone pillar, to his right but within vision, straightened and barked an order to him, “Halt!” At the first turn he saw that the aisle merely circled the stairway, coming out into the depot again on the other side. It took him only a few seconds to push the case into the compartment, lock it and slide the key along the floor beneath the locker. But the fact that they had been expecting him meant that others would very probably be waiting outside. A tall ruffian, copper-brown face damp with perspiration and body oil, grabbed him by the jacket and slammed him back against the lockers. The day was hot, and the room had no air conditioning, still a rare luxury on St. Martin’s. It rose in a foot-high wave and rolled gently toward the far wall. The floor continued its transmutation, and Zarwell sank deep into viscous depths. Zarwell grunted acknowledgment and pushed himself to his feet, apparently unaware that his shirt clung damply to his body. The white marble of the city’s buildings shimmered in the afternoon heat, squat and austere as giant tree trunks, pock-marked and gray-mottled with windows. The evening meal hour was approaching when he reached the Flats, on the way to his apartment. The feeling was there again, like a scene waiting only to be gazed at directly to be perceived. He moved in and joined a party of short, bearded men, directing them as they battered at the wall with a huge log mounted on a many-wheeled truck.
