The next important work was the establishment of the British American Manual Labor Institute in connection with Reverend Hiram Wilson. After working out a tentative plan, Wilson wrote James O. Fuller, residing in the State of New York, and interested him in the free Negroes of Canada West. On a trip to England Mr. Fuller raised $1,500 for this purpose. A convention of the leading refugees in Canada West was then called to decide exactly how this money should be spent. Henson urged that it be appropriated to the establishment of a manual labor school, where children could be taught the elements of knowledge which are usually the courses of a grammar school; and where the boys could be given, in addition, the practice of some mechanic art and the girls could be instructed in those domestic arts which are the proper occupations of their sex. Such a school he though would so equip the Negro youth as to enable him to take over much of the work then being done by white teachers. This was then necessary, owing to the prejudice arising against the coeducation of the whites and blacks and the stigma attached to teachers of Negroes. For this purpose two hundred acres of land were bought on the river Sydenham. In 1842 the school was established at Dawn, to which Henson moved with his family. Henson traveled in New York, Connecticut, Massachusetts and Maine in the interest of the institution and obtained many gifts, especially from Boston, the liberal people of which gave him sufficient funds to maintain it some time. In connection with this school there was established a saw-mill, the building and the equipment of which was secured by Henson also from philanthropists in Boston. These gentlemen were Rev. Ephraim Peabody, Amos Lawrence, H. Ingersoll Bowditch, and Samuel Elliot. Henson then proceeded to have walnut sawed in Canada and shipped to Boston. He sold his first eighty thousand feet to Jonas Chickering, at forty-five dollars a thousand. The second cargo was shipped to Boston via the St. Lawrence and brought Henson a handsome profit. This business not only became profitable to the persons directly interested in it but proved to be an asset of the whole section.
