He was deeply concerned on account of that inhuman and iniquitous Practice of making Slaves of the People of _Africa_, or holding them in that State; and, on that Account, we understand he hath not only written some Books, but travelled much on the Continent of _America_, in order to make the Negro-masters (especially those in Profession with us) sensible of the evil of such a Practice; and though, in his Journey to _England_, he was far removed from the outward Sight of their Sufferings, yet his deep Exercise of Mind remained, as appears by a short Treatise he wrote in this Journey, and his frequent Concern to open the miserable State of this deeply-injured People. His Testimony in the last Meeting he attended was on this Subject; wherein he remarked, that as we, as a Society, when under outward Sufferings, had often found it our Concern to lay them before those in Authority, and thereby, in the Lord's Time, had obtained Relief, so he recommended this oppressed Part of the Creation to our Notice, that we may, as way may open, represent their Sufferings, in an Individual, if not a Society Capacity, to those in Authority. Deeply sensible that the Desire to gratify People's Inclinations in Luxury and Superfluities is the principal Ground of Oppression, and the Occasion of many unnecessary Wants, he believed it to be his Duty to be a Pattern of great Self-denial with Respect to the Things of this Life, and earnestly to labour with Friends in the Meekness of Wisdom, to impress on their Minds the great Importance of our Testimony in these Things, recommending to the Guidance of the blessed Truth in this and all other Concerns, and cautioning such as are experienced therein against contenting themselves with acting up to the Standard of others, but to be careful to make the Standard of Truth, manifested to them, the Measure of their Obedience; for, said he, "that Purity of Life which proceeds from Faithfulness in following the Spirit of Truth, that State where our Minds are devoted to serve God, and all our Wants are bounded by his Wisdom,--this Habitation has often been opened before me, as a Place of retirement for the Children of the Light, where they may stand separated from that which disordereth and confuseth the Affairs of Society, and where we may have a Testimony of our Innocence in the Hearts of those who behold us." We conclude with fervent Desires that we, as a People, may thus, by our Example, promote the Lord's Work in the Earth; and, our Hearts being prepared, may unite in Prayer to the great Lord of the Harvest, that as, in his infinite Wisdom, he hath greatly stripped the Church, by removing of late divers faithful Ministers and Elders, he may be pleased to send forth many more faithful Labourers into his Harvest. _Signed in, by Order, and on Behalf of, said Meeting_:
