Bactcrinlogij and agriculture.—In agriculture, the de- velopment of bacteriology has given us a new insight into the nature of soil fertilit)^ We have learned to regard the soil as a culture medium with its almost endless number of species and varieties of bacteria, specialized to do important work in the transformation of soil, nitrogen, carbon, hydrogen, sulfur; in the tran,s-.
