Elementary Science by Grades Book Four: A Nature Study and Science Reader
Elementary Science by Grades Book Four is a 1929 nature study reader by Ellis C. Persing and Edward E. Wildman, published by D. Appleton and Company for elementary school pupils. Its photographs show birds gathered at a ground hollow, two turtles on a submerged log, a rural landscape seen sideways, and a branch of conifer with cones; a designer could take from them a plain, documentary style of natural history photography with strong tonal contrast and simple outdoor compositions.
