How does James Salter use imagery in A Sport and a Pastime?

Example of Imagery:

"Finally we emerge at the roaring, iron galleries where meat is handled. It's like coming upon a factory in the darkness. The overhead lights are blazing. The smell of carnage is everywhere, the very metal reeks with an odor denser than flowers. On the sidewalk there are wheelbarrows of slaughtered heads. It's right out of Franju and that famous work which literally steams of it. We stare down at the dumb victims. There are scores of them. The mouths are pink, the nostrils still moist. Worn knives with the edge of a razor have flensed them while their eyes were still fluttering, the huge, eloquent eyes of young calves."
