All persons coming to the Convention must bring credentials properly authenticated, or bring verbal assurance to the Committee on Credentials-appointed for the purpose-of their fidelity to the measures and objects set forth in this call, as the Convention is specifically by and for the friends of Emigration, and none others-and no opposition to them will be entertained. The question is not whether our condition can be bettered by emigration, but whether it can be made worse. If not, then, there is no part of the wide spread universe, where our social and political condition are not better than here in our native country, and nowhere in the world as here, proscribed on account of color.
