 On returning to Guyana he founded his own school, The Guyanese Academy (1926–34), and wrote "The Evolution of the Negro", published in two volumes (1929 and 1934), which Kenneth Ramchand has called "A rare and neglected but very useful work".In 1934 Cameron returned as a Senior Master to his alma mater, Queen's College, to teach mathematics, and to contribute to the development of his school.While teaching at Queen's College, he wrote several dramatic works, published an anthology of Guyanese poetry, wrote numerous essays, memoranda and articles on the culture and politics of Guyanese life, and authored four high-school text books on mathematics (1942), as well as the history of Queen's College (1951).
