the act of congress confines the description of aliens capable of naturalization to "free white persons." i presume that this excludes the inhabitants of africa, and their descendants; and it may become a question, to what extent persons of mixed blood, as mulattoes, are excluded, and what shades and degrees of mixture of colour disqualify an alien from application for the benefits of the act of naturalization. Perhaps there might be difficulties also as to the copper-coloured natives of america, or the yellow or tawny races of asiatics, though i should doubt whether any of them were "white persons" within the purview of the law. It is the declared law of this state, that indians are not citizens, but distinct tribes, living under the protection of the government, and, consequently, they never can be made citizens under the act of congress.
