This is an image of WW II soldiers using DDT. I would use this image on page 21 between the first and second paragraph. This would help to illustrate how DDT was applied during the second world war. Oddly enough, the guy getting sprayed looks like a young George W. Bush to me.
This is the chemical structure of the aldrin insecticide. It shows the chemical relation between dieldrin and aldrin. I would place this image on page 26 between the second and third paragraph.
Next is an image of a crop dusting aircraft. Carson expresses that this is the usual means by which parathion is administered on page 30. I would place this image at the end of the first paragraph on the same page.
