"I give my above said house and lot, or ground-rent proceeding from it, and the rest and residue of my estate which shall remain undisposed of after my wife's decease, both real and personal, to the public school of Philadelphia, founded by charter, and to their successors forever, in trust, that they shall sell my house and lot on perpetual ground-rent forever, if the same be not already sold by my executors, as before mentioned, and that as speedily as may be they receive and take as much of my personal estate as may be remaining, and therewith purchase a yearly ground-rent, or ground-rents, and with the income of such ground-rent proceeding from the sale of my real estate, hire and employ a religious-minded person, or persons, to teach a number of negro, mulatto, or Indian children to read, write, arithmetic, plain accounts, needle-work, etc. And it is my particular desire, founded on the experience I have had in that service, that in the choice of such tutors, special care may be had to prefer an industrious, careful person of true piety, who may be or become suitably qualified, who would undertake the service from a principle of charity, to one more highly learned, not equally disposed; this I desire may be carefully attended to, sensible that from the number of pupils of all ages, the irregularity of attendance their situation subjects them to will not admit of that particular inspection in their improvement usual in other schools, but that the real well-doing of the scholars will very much depend upon the master making a special conscience of doing his duty; and shall likewise defray such other necessary expense as may occur in that service; and as the said remaining income of my estate, after my wife's decease, will not be sufficient to defray the whole expense necessary for the support of such a school, it is my request that the overseers of the said public school shall join in the care and expense of such school, or schools, for the education of negro, mulatto, or Indian children, with any committee which may be appointed by the monthly meetings of Friends in Philadelphia, or with any other body of benevolent persons who may join in raising money and employing it for the education and care of such children; my desire being that as such a school is now set up, it may be forever maintained in this city." Just before his death he addressed the following note to the "overseers of the school for the instruction of the black people."
