The Treatise of Taxes and Contributions is the earliest of Petty's economic writings. Since it mentions Graunt's Observations, published in January, 1662, as "lately made," and inasmuch as Petty was in Ireland before the end of October, the Treatise was probably composed in the early months of 1662. About this time Petty, relieved from his political anxieties, returned with vigour to his scientific pursuits. He experimented with the Double Bottom, and wrote, in addition to the Treatise, his Discourse concerning the Making of Cloth, his Apparatus to the History of Dying, and a paper on shipping.
