Book excerpt: Excerpt from Heredity in Relation to Evolution and Animal Breeding The existence of civilized man rests ultimately on his ability to produce from the earth in suf ficient abundance cultivated plants and domes ticated animals. City populations are apt to forget this fundamental fact and to regard with indifierence bordering at times on scorn agri cultural districts and their workers. But let the steady stream of supplies coming from the land to any large city be interrupted for only a few days by war, floods, a railroad strike, or any similar occurrence, and this sentiment vanishes instantly. Man to live must have food, and food comes chiefly from the land. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
