[1226] It is doubtful whether any definite knowledge of the enslavement of Indians existed in England. The public criticism of the play and opera “Incle and Yarico,” which dealt with the capture of two Indian girls in America and their subsequent sale in Barbadoes, because the first scene was laid in America, tends to show a general ignorance on the subject. This play written by Coleman and told in story by Steele in “The Spectator,” No. 11, March 13, 1710, is supposed to have been founded on fact. The event is described in Ligon, _History of Barbadoes_, p. 55. The play is given in Inchbald, _British Theatre_. [1227] _Massachusetts Historical Society Collections_, series 4, vi, p. 214.

In 1700, Sewall had published a protest against slavery in general in the form of a tract: _The Selling of Joseph, a Memorial_. The tract did not mention Indian slavery.

According to custom the action of the Yearly Meeting was at once made known to the various Quarterly Meetings within its jurisdiction by extracts from its minutes. Such extracts recorded in the minutes of the various Quarterly Meetings for the year 1719 contain exactly the same expression: “And to avoid giving them occasion of discontent, it is desired that Friends do not buy or sell Indian slaves.” [1236] After 1719 the records show the opposition of the Yearly Meeting to have been expressed against slavery in general, and no mention is made of Indian slaves, though the records sometimes read: “negroes and other slaves.” For the action of the Yearly Meeting at various times up to the time of the abolition of slavery in Pennsylvania in 1780, see _Pennsylvania Historical Society Memoirs_, i, p. 392 _et seq._; Sharpless, _A History of Quaker Government in Pennsylvania_, ii, p. 224 _et seq._; _American Society of Church Publications_, v. ii, (article by Allen C.
