Corn Trade.- Torrens (Robert) An Essay on the External Corn Trade, third edition, title and dedication leaf with old tape stains to inner margin, R.D.Collison Black's copy with his signed book-label, contemporary half calf, rubbed, rebacked preserving old gilt spine, [Goldsmiths' 24886; Kress C1807], 1826 § Grounds and Danger (The) of Restrictions on the Corn Trade considered; together with a letter on the substance of rent, second edition, half-title (soiled), modern cloth, [Goldsmiths' 24876; cf. Kress C542, first edition], 1826 § Jacob (William) Tracts relating to the Corn Trade and Corn Laws, first collected edition, ex-Rothamsted Agricultural Library copy with ink stamp to front pastedown, original cloth-backed boards (boards recovered), uncut, 1828; and 3 others on the corn trade and corn laws, 8vo (6)

⁂ The first is one of Torrens's most important contributions to political economy. The Essay was a landmark, first published in 1815. Ostensibly as a response to the immediate practical issue of protection to agriculture it proceeded to develop many of the basic concepts of classical political economy, and presented Torrens' independent discovery of the modern theory of rent.
