[13] Jonathan Dickinson, a merchant of Philadelphia, writing to a correspondent in Jamaica, 4th month, 1715, says, "I must entreat you to send me no more negroes for sale, for our people don't care to buy. They are generally against any coming into the country." I have been unable to find this letter. Watson, who quotes it (_Annals of Philadelphia_, II, 264), says, "Vide the Logan MSS." _Cf._ also a letter of George Tiller of Kingston, Jamaica, to Dickinson, 1712. MS. Logan Papers, VIII, 47.

During this period negroes were being imported through the custom-house at the rate of about one hundred and fifty a year. _Cf._ _Votes and Proceedings_, II, 251. [15] In 1727 the iron-masters of Pennsylvania petitioned for the entire removal of the duty, labor being so scarce. _Votes and Proceedings_, 1726-1742, p. 31. The attitude of the English authorities is explained in a report of Richard Jackson, March 2, 1774, on one of the Pennsylvania impost acts.

Ralph Sandiford says (1730), "We have _negroes_ flocking in upon us since the duty on them is reduced to 40 shillings per head." _Mystery of Iniquity_, (2d ed.), 5. Many of these were smuggled in from New Jersey, where there was no duty from 1721 to 1767. Cooley, _A Study of Slavery in New Jersey_, 15, 16.

As to enlistment of servants _cf._ _Mercury_, _Gazette_, Aug. 7, 1740; _Col. Rec._, IV, 437. Complaint about this had been made as early as 1711. _Votes and Proceedings_, II, 101, 103.
