In discoursing with these, however strenuous he might appear, he seems never to have departed from a calm, modest, and yet dignified and even friendly demeanour.

At the public meetings for discipline, held by his own Society in these provinces, he endeavoured to display the same truths and in the same manner, but particularly to the elders of his own Society, exhorting them, as the most conspicuous rank, to be careful of their conduct, and to give a bright example in the liberation of their slaves.

He visited also families for the same purpose: and he had the well-earned satisfaction of finding his admonitions kindly received by some, and of seeing a disposition in others to follow the advice he had given them.
In the year 1758, he attended the yearly meeting at Philadelphia, where he addressed his brethren on the propriety of dealing with such members, as should hereafter purchase slaves.

On the discussion of this point he spoke a second time, and this to such effect that he had the satisfaction at this meeting to see minutes made more fully than any before, and a commitee appointed, for the advancement of the great object, to which he had now been instrumental in turning the attention of many, and to witness a considerable spreading of the cause.

In the same year also, he joined himself with two others of the Society to visit such members of it, as possessed slaves in Chester county.
