A Quote by Edwin T. Morris on animals, kindness, and practice

The practice of intensive manuring emerged as the dominant mark of the Chinese system. All human and animal nitrogenous wastes were carefully husbanded in large terra-cotta vats where they were aged, and then ladled into irrigation ditches. Every 2,000 pounds of night soil provided 12.7 pounds of nitrogen, 4 pounds of potassium, and 1.7 pounds of phosphorus. Ashes were added to this compost from any kind of fire.
