chemistry, agricultural botany and agricultural engineering. Alfred Daniel Hall removed to Rothamsted in 1902 to continue his marriage of agriculture and science. At Wye he was replaced as principal by his Oxford contemporary Malcolm Dunstan, formerly director of the Midland Agricultural and Dairy Institute. Hall's departure was promptly followed by opening botany lecturer and vice-principal John Percival who moved to the University of Reading and became founding father of the faculty of agriculture there. Seeds Percival took with him formed the nucleus of a native European wheat variety collection eventually numbering over 2,500 varieties in the 1930s. John Russell had joined the college in 1901 and took over chemistry teaching from Henry Cousins. Russell began research into soil microbiology determining that oxygen uptake could be used to measure micro-organism activity in a soil sample. However, he too departed in 1907 taking up an invitation to rejoin Hall at Rothamstead. In 1968, Wye College's Russell Laboratories were named for him. In 1903, the college appointed C S Orwin its lecturer in farm management and book-keeping. At opening he had been the first potential student interviewed by Hall and went on to be treasurer of the college's students' union in its first year. Orwin remained on staff for three years and was later appointed by Hall to lead the Department of Agricultural Economics created at Oxford. Academics at Wye sought early ways to establish the actual cost of agricultural products on farm, albeit with varied success, and double entry book-keeping was then a part of the curriculum. In 1913, East Malling and Wye Fruit Experimental Station established on bought by Kent County Council at East Malling. It was under the college's control and initially advised by botanist V H Blackman of Imperial College. Ronald Hatton was appointed director of the station in 1914 and remained in post for the rest of his career. Hatton prioritised basic research; was concerned about the conditions of horticultural workers like fellow socialist Hall, and merely tolerated requests for practical advice from growers. The station became independent of the college in 1921. The 1894 premises included chemical and biological laboratories. By 1901 expansion meant rooms could be dedicated to a drawing office as well as botany, zoology and analytical laboratories. With completion of works in 1914, space would be made available to support study of agriculture, horticulture, entomology, mycology, dairying, engineering, economics and physics. There was an
