[38] A Report of the Royal African Company, Nov. 2, 1680, purports to show the first cost: "That the Negros cost them the first price 5li: and 4li: 15s. the freight, besides 25li p cent which they lose by the usual mortality of the Negros." MS. Board of Trade Journals, III, 229. The selling price had been considered immoderate four years previous. _Ibid._, I, 236. In 1723 Peter Baynton sold "a negroe man named Jemy ... 30 £." Loose sheet in Peter Baynton's Ledger. In 1729 a negro twenty-five years old brought 35 pounds in Chester County. MS. Chester County Papers, 89. The Moravians of Bethlehem purchased a negress in 1748 for 70 pounds. _Pa. Mag._, XXII, 503. Peter Kalm (1748) says that a full grown negro cost from 40 pounds to 100 pounds; a child of two or three years, 8 pounds to 14 pounds. _Travels_, I, 393, 394. Mittelberger (1750) says 200 to 350 florins (33 to 58 pounds). _Journey to Pennsylvania in the Year 1750_, etc., 106. Franklin (1751) in a very careful estimate thought that the price would average about 30 pounds. _Works_ (ed. Sparks), II, 314. Acrelius (about 1759) says 30 to 40 pounds. _Description of ... New Sweden_, etc. (translation of W. M. Reynolds, 1874, in _Memoirs of the Historical Society of Pennsylvania_, XI), p. 168. A negro iron-worker brought 50 pounds at Bethlehem in 1760. _Pa. Mag._, XXII, 503. In 1790 Edward Shippen writes of a slave who cost him 100 pounds. _Ibid._, VII, 31. It is probable that the value of a slave was roughly about three times that of a white servant. _Cf. Votes and Proceedings_ (1764), V, 308. [39] In 1708 the Board of Trade requested the governor of Pennsylvania that very definite information on a variety of subjects relating to the negro be transmitted thereafter half yearly. Were these records available they would be worth more than all the remaining information. _Cf._ MS. Provincial Papers, I, April 15, 1708; 1 _Pa. Arch._, I, 152, 153.
