In 1849, a statistical return of the condition of the people of color in the city and districts of Philadelphia shows that there were then one grammar school, with 463 pupils; two public primary schools, with 339; and an infant school, under the charge of the Pennsylvania Abolition Society, of 70 pupils, in Clifton Street: a ragged and a moral-reform school, with 81 pupils. In West Philadelphia there was also a public school, with 67 pupils; and, in all, there were about 20 private schools, with 300 pupils; making an aggregate of more than 1,300 children receiving an education. In 1859, according to Bacon's "Statistics of the Colored People of Philadelphia," there were 1,031 Colored children in public schools, 748 in charity schools of various kinds, 211 in benevolent and reformatory schools, and 331 in private schools, making an aggregate of 2,321 pupils; besides four evening schools, one for adult males, one for females, and one for young apprentices. There were 19 Sunday-schools connected with the congregations of the Colored people, and conducted by their own teachers, containing 1,667 pupils, and four Sunday-schools gathered as mission schools by members of white congregations, with 215 pupils. There was also a "Public Library and Reading-room" connected with the "Institute for Colored Youth," established in 1853, having about 1,300 volumes; besides three other small libraries in different parts of the city. The same pamphlet shows that there were 1,700 of the Colored population engaged in different trades and occupations, representing every department of industry.[64] In 1794, the Pennsylvania Abolition Society established a school for children of the people of color, and in 1809 erected a school building at a cost of four thousand dollars, which they designated as "Clarkson Hall," in 1815. In 1813, a board of education was organized consisting of thirteen persons, with a visiting committee of three, whose duty it was to visit the schools once each week. In 1818, the school board, in their report, speak very kindly and encouragingly of the Clarkson Schools, which, they say, "furnish a decided refutation of the charge that the mental endowments of the descendants of Africa are inferior to those possessed by their white brethren. We can assert, without fear of contradiction, that the pupils of this seminary will sustain a fair comparison with those of any other institution in which the same elementary branches are taught."
