This is a training booklet published by the renown French-American chemist and industrialist, E. I. du Pont de Nemours, who founded a gunpowder manufacturing company. In it Du Pont advocates for the use of his company's Red Cross Gunpowder as a handy item for farmers. Among the uses he explains in farming include: clearing land of stumps, trees and boulders, breaking up Hard-Pan, Shale, or Clay Sub soils, plowing, planting and cultivating orchards, digging ditches, post holes, wells and reservoirs, road-making and grading, excavating cellars and foundation trenches and regenerating old, worn-out farms.
