Samuel Slater opened a school for his operatives in Pawtucket, Rhode Island, in 1797. The Broadway Baptist Sabbath-school, in Baltimore, was established in 1804, and it is said to be still in operation. Mrs. Amos Tappan (Miss Buckminster) opened a Sabbath-school in Portsmouth, New Hampshire, in 1803. We do not learn that the Churches and organized Christian bodies took hold of the Sabbath-school movement in this country, so as to _produce_ permanent and efficient _action_, until 1809, when we find an elaborate constitution and plan of action from Pittsburgh, Pennsylvania. In 1810 a Sabbath-school was organized in Beverly, Massachusetts, and in Boston in 1812. Soon after this there began to be a more general and awakened interest in the Churches in behalf of Sabbath-schools, and the years 1814, 1815, and 1816 were years of most triumphant progress, so that in 1817 Sunday-schools were organized in most of our flourishing churches and Christian communities throughout this country. Early in 1816 the New York Sunday-School Union was established, and is the first and oldest Union in our land, having just celebrated its semi-centennial. The American Sunday-School Union was organized in 1824, to provide a juvenile Christian literature (and from whence our public school district libraries borrowed their first idea) and to plant a Sunday-school wherever there is a population. Surely, if any work in our land needs to be hastened, it is that of the religious instruction of the neglected children and youth of this nation by means of Sabbath-schools. Not to mention the various modern denominational movements, the above we believe to be a correct history of the Sunday-school progress, and we suppose it to be sufficiently full for practical purposes in this work. We have ample materials on this subject to fill a large volume, but this may here suffice. There are other questions, however, which ought to be here recorded in connection with the progress of the cause. In Great Britain the work is embarrassed from the fact that as a general rule only the children of the poor and middle classes attend their Sabbath-schools. In the early stages of the Sabbath-school movement in this country the same custom prevailed here, and it is certainly worthy of record by what means the change was effected.
