In the forest the deposit of organic substances upon the surface of the soil in the form of leaves, twigs, bark and other vegetative residues is perhaps the most conspicuous feature of the ground. This material in a well-stocked forest amounts to from 3,000 to 5,000 pounds per acre per year on the basis of measurements reported by Henry (s) and others. Our own measurements in ay-year-old pine plantations give figures ranging from 2,000 to 3,000 pounds. This does not include the under ground residues derived from roots, fungal mycelia, insects, earthworms, and microbial cells to which no numerical values can be assigned. The transformation of this organic
