How does Jerry Stanley use imagery in Children of the Dust Bowl: The True Story of the School at Weedpatch Camp?

Examples of Imagery:

"'The dust storms scared us to pieces,' Bessie said. 'It was dark as the middle of the night, and it stayed that way all day.'"

"The bad sanitary conditions and inadequate diet led to epidemics of dysentery, tuberculosis, and pneumonia. 'Even if we found work,' one squatter said, 'the people starved. We lived like animals.'"

"And so Weedpatch School started with no grass, no sidewalks, no playground equipment, no toilets, no water, no books, no teachers. It started...with two condemned buildings that had been in the field for years and with 'fifty poorly clad, undernourished, and skeptical youngsters.'"
