He was a prolific writer in a variety of genres - evidence of his intelligence and the range of his talents. He wrote some manuscript notes and miscellaneous poems. He is believed to have written several pamphlets, published anonymously or left in manuscript, including a "Traité de la polygamie", which he had talked about. He was also a musician, a calligrapher, and a draughtsman. Canadian folklorists can claim him, since he was the first to record the notation of Indian songs.
