The question of soil exhaustion was first raised by W. Denton, who rejected Thorold Rogers’ favorable views of the medieval economy, using Rogers’ wage data to point to a secular decline in population from 1315 and questioning Rogers’ assumption that wage-earners had enough employment to get an adequate yearround living. See , Denton'sEngland in the Fifteenth Century (London, 1888). William Cunningham in the later editions of his The Growth of English Industry and Commerce During the Early and Middle Ages (first published in 1882) picked up both points but did not allow them to cloud his more optimistic view.
