It is very desirable to have a course of regular week-day evening lectures for the children and parents. One week it may be "Jerusalem," another "coal," another "coral," and the next "the ocean," and then some subject of natural history, as the "elephant;" and illustrate highly to meet the eyes. Take especial care of the older boys and girls, and strive to introduce week-day exercises that will interest and please them. Appoint them upon committees and to little offices, and give them all something to do--something that they can do, something that they will do cheerfully. The following, from _The Sunday-School Times_, is a beautiful illustrative example of mission Sunday-school work and teaching. It is entitled "Bill Jones; or, Our Colored Sabbath-school:" It was one of those perfect Sabbaths in the early June, that I walked with trembling heart along the locust-shadowed sidewalk leading to our little chapel. On that day our colored Sunday-school was to be organized; and we, who only a few weeks since had professed before men and angels to love our Saviour, were to be enlisted as workers in our Master's vineyard. What can be done to improve the religious condition of our colored population? was a question which had long occasioned anxious thought among the godly of our village. Originally slaves, they had, when the law of liberation was proclaimed through New York, refused to remove farther than the grassy common, where, almost within the shadow of "Massa's house," they were allowed to build their humble cabins. Increased afterward in numbers, the suburbs of the town had become edged with their miserable tenements. One or two attempts had been made to establish preaching among them by a minister of their own race, but thus far without success. True, in the "brick church," a part of the gallery was set apart especially for their use. Still the "dark corner" (as the mischievous boys called it) was only occupied by a few old uncles and aunties, while the rest, though within sound of the sweetest of all Sabbath bells, were as utterly without God in the world as their brethren in Africa. At length a Sabbath-school was determined on. As most of those able and willing to work were already engaged, one of the officers of the church volunteered to superintend the school, provided he might have the assistance of a band of young girls, who hitherto had been privileged to assemble week after week as a Bible-class in the "pastor's study."
