Even as late as the mid-century shipments of deerskins exceeded in value the combined returns from indigo, cattle, beef and pork, lumber and naval stores. 7 [Note 7: James Glen, Description, 1761, pp. 50-55, reprinted in Carroll (ed.), Collections, II. 234-8 (account of exports, 1747-1748). Rice produced about three times the returns from the Indian trade. Cf. account of exports 1748-1749 in C.O. 5 :372, I 60. Total value of exports was £1,027,440 6s. 15d. currency, or £144,777 3s. 9d. sterling; of deerskins £187,250 curr.; of rice £615,510. Sterling exchange was about 700 to 100.] The prosperity of South Carolina, wrote a colonial economist of the mid-century, had been achieved-from 'its Soil and Climate, producing a good Staple, the best of Rice; and from a neighboring vast Indian Country affording large Quantities of Deer-Skins.'8 [Note 8: [William Douglas], Postcript to a Discourse concerning the Currencies, reprinted in Currency Reprints (Prince Society Collections), IV. 52.]
