Roy B. Kester, Accounting theory and practice… (1922)
“ No industry has escaped the seemingly inevitable trend towards the displacement of the old and antiquated but not worn-out equipment, by newer, more up-to-date, and more economical equipment. Obviously the last word has not yet been spoken or the last refinement been made in the development or application of art and science to any industrial enterprise. Life means development; dry rot and retrogression are the fate of any art, any industry, any people which has reached the limit of its development. ”
