How does Henry Roth use imagery in Call It Sleep?

Example of Imagery:

She lifted the sobbing child to her breast, pressed him against her. With a vacant stunned expression, her gaze wandered from the grim smoldering face of her husband to the stern of the ship. In the silvery-green wake that curved trumpet-wise through the water, the blue hat still bobbed and rolled, ribbon stretched out on the waves. Tears sprang to her eyes. She brushed them away quickly, shook her head as if shaking off the memory, and looked toward the bow. Before her the grimy cupolas and towering square walls of the city loomed up. Above the jagged roof tops, the white smoke, whitened and suffused by the slanting sun, faded into the slots and wedges of the sky. She pressed her brow against her child's, hushed him with whispers. This was that vast incredible land, the land of freedom, of immense opportunity, that Golden Land. Again, she tried to smile.
