PROBLEM: Question: How many years did the Great Depression last? Passage:Originally from New Brunswick, Harrison graduated from Nova Scotia Agricultural College in 1922, and, in 1924, from the Ontario Agricultural College with a B.Sc. in agriculture. He earned an MSc in plant pathology from Macdonald Campus of McGill University a year later. A doctoral degree he started at the University of Toronto in 1929 was abandoned due to the Great Depression. He established a herbarium of mycological specimens where he was employed for many years at the Kentville Research Station (now the Atlantic Food and Horticulture Research Centre); most of his collections are now housed at the Canadian National Mycological Herbarium. His early research concerned the fungal infestation of plants, such as that of Colletotrichum lindemuthianum on beans (Phaseolus). Working with John Frederick DeWitt Hockey, they made many contributions to the control and prevention of diseases of horticultural crops. They were among the first to use the sticky slide spore trap to estimate the densities of fungal spores.
