ABSTRACT
A manuscript on the analysis of land forms submitted to him late in 1925 referred to the work of Powell, Gilbert, Dutton, and Davis. It ascribed to Davis more credit than he wished to take for the development of physiography. He edited a paragraph to read as follows,… ‘Powell’s work was noteworthy for the forceful ideas it conveyed of base-levelled surfaces; Gilbert and Dutton excelled in their analyses of individual features, Davis systematized the sequence of forms through an ideal cycle and provided a terminology.’
