 "The Mount Lyell Mining Field, Tasmania", was published in 1905.This does not give a complete impression of Gregory's activities in Australia, for he was director of the Geological Survey of Victoria from 1901, in which year he was elected a fellow of the Royal Society, London, and he was able also to find time for university extension lecturing.In 1904 Gregory was awarded the Chair in Geology at Glasgow University winning against Thomas James Jehu, Philip Lake and others.
