A 1920 U.S. Department of Agriculture bulletin by Luther P. Byars and William W. Gilbert, reporting hot-water soil treatment against root-knot nematodes and soil fungi for growers and field agents. Halftone photographs set washed root systems against black and white grounds, with lettered comparisons of potted seedlings, giving stark branching silhouettes and gritty greenhouse still lifes.
