As the old objections are revived, so again do I present the great truth announced by our fathers in the Declaration of Independence, “that all men are created equal.” Admitting this principle as a rule of conduct, the separation of children in the public schools on account of color is absolutely indefensible. In abolishing it we simply bring our schools into conformity with the requirements of the Declaration. To the objection that this change will injure the schools, I reply that this is contrary to experience in other places, where the commingling of children according to the genius of republican institutions has been found excellent in influence. And I further reply by insisting now, as I always do, upon that justice to an oppressed race which has been too long delayed, and which never fails to be a well-spring of strength and happiness, blessing all who help it and all who receive it. Feeling as I do on this question, you will understand that I cannot see without regret any opportunity neglected of advancing the cause, especially among colored fellow-citizens. On this they should be a unit. Wherever the question presents itself, whether in Congress, or the Legislative Chambers of the District, or the popular assembly, there should be a solid vote against every discrimination on account of color. It is easy for lawyers and politicians to find excuses according to their desires; but no fine-spun theory or technicality should be allowed to prevail against the commanding principle. Accept my best wishes, and believe me, Gentlemen, Your faithful friend, CHARLES SUMNER. HENRY PIPER, Chairman. BOSTON: ITS PROPER BOUNDARIES. LETTER TO HON. G. W. WARREN, OF CHARLESTOWN, ON THE ANNEXION TO BOSTON OF THE SUBURBAN TOWNS, OCTOBER 4, 1873. COOLIDGE HOUSE, October 4, 1873. DEAR MR. WARREN,--I should be glad to meet your friends in a conference on the question, How Boston shall be rounded so as to be in reality itself. I cannot meet with you, but I unite in your purpose, as I understand it, and especially with regard to Charlestown. I doubt if the future Boston will be content until it holds and possesses all the territory which hugs the harbor bearing its name, so that in Boston harbor nobody shall land except in Boston. Evidently Boston should contain all Bostonians, which it does not now. I know no better way of accomplishing this result than by widening the circle of its jurisdiction.
