The Presbytery of Roanoke, Virginia, (O. S.) has addressed a Pastoral letter, on the instruction of the colored people, to the churches under its care, and ordered the same to be read in all the churches of the Presbytery, in those that are vacant, as well as where there are pastors or stated supplies. It commences by saying: "Among the important interests of the kingdom of our Lord Jesus Christ, which have claimed our special attention since the organization of the Presbytery in April last,--that the work of the Lord may be vigorously and efficiently carried forward within our bounds,--_the religious instruction of the colored people_, is hardly to be placed second to any other." After speaking of the obstacles and encouragements to the work, it gives the following statistics: "In the Presbytery of Charleston, S. C., 1637 out of 2889 members, or considerably over one-half, are colored. In the whole Synod of South Carolina, 5,009 out of 13,074, are colored members. The Presbyteries of Mississippi and Central Mississippi, of Tuscaloosa and South Alabama, of Georgia, of Concord, and Fayetteville, also show many churches with large proportions of colored communicants, from one-third to one-seventh of the whole. Our own Presbytery reports 276 out of 1737 members. In the whole of the above mentioned bodies, there are 9,076 colored, out of 33,667 communicants. Among the churches of these Presbyteries, we find twenty with an aggregate colored membership of 3,600, or an average of 130 to each. We find also, such large figures as these, 260, 333, 356, 525! These facts speak for themselves and forbid discouragement." Speaking of the obligations to instruct this class, the letter says:
