Abstract
THIS treatise, first published in 1936, is now recognized as the standard text-book of the science of humus, or ‘humology’, as the science has been called. The literature of humus is so diffused that the treatment of the subject in agricultural and soil science text-books must necessarily be somewhat superficial and inadequate to the importance of the subject. The fact that the chemistry, physics and biology of humus do not lend themselves to easy interpretation in terms of orthodox science is the main stumbling-block to progress in knowledge of the soil.
