It is said that it is not good for man to be alone. This is true, not only in the sense in which our women's rights' friends so zealously and wisely teach, but it is true as to nations. The voice of civilization speaks an unmistakable language against the isolation of families, nations and races, and pleads for composite nationality as essential to her triumphs. Those races of men who have maintained the most distinct and separate existence for the longest periods of time; which have had the least intercourse with other races of men are standing confirmation of the folly of isolation. The very soil of the national mind becomes in such cases barren, and can only be resuscitated by assistance from without.
