Several of his writings testify to his acquaintance with the course of trade and interest in public matters. He published in 1680 "A Plea for the bringing in of Irish Cattel, and keeping out Fish caught by Foreigners, together with an humble Address to the Honourable members of parliament of the counties of Cornwall and Devon, about the Advancement of Tin, Fishery, and divers Manufactures"; and in 1682 a little treatise entitled "Salt and Fishery", in which he dwelt upon the several modes of preparing salt in England and abroad, the catching of fish, the salting and cooking of fish and meat, besides offering proposals for the relief of the salt-workers.
