Dickson put emphasis on the physiological aspects of host-parasite interactions, and to strengthen that part of the plant pathology program, John G. Coulson (1893-1974) was added to the teaching staff as lecturer in 1921. Coulson had served in the Royal Air Force and had been a school teacher in Ontario. He had obtained B.A and M.A. degrees from Queen’s University, where he had majored in botany and won a gold medal for highest standing in chemistry. In addition to his teaching of botany at Macdonald College, Coulson assisted Dickson with the teaching of plant pathology, especially the laboratory parts of the courses, some of which became Coulson’s own courses.
