questioned if slavery had been abolished by the proclamation and its enforcement by the union armies. But this, strong as it was, would not have been the true theory. The true theory--the real fact--is that at the outbreak of the brothers' war, and long before, the States had become more closely connected than the Siamese Twins,--indissolubly united as integral parts of the same organism, like the different trunks of the Banyan tree; and while the southern nationalization was opposing the union forces with might and main, it was really but an excrescence, with roots far more shallow than those of the American union--a parasite like the mistletoe, growing upon the American body politic, fated to die of itself if not destroyed by its fell foe. For, as we have explained, the sole motor of this southern nationalization--slavery--could no more maintain itself permanently against free labor than the handloom could stand against the steam-loom, or the draft-horse can much longer compete with artificial traction power. Now let us rapidly set in array the stronger supports of this true theory. We should start with the impulse to combine which adjacency always gives to communities of the same origin; and external compression and joint interest to those of diverse origin, as we see in the case of the Swiss. How clearly does our great American sociologist trace the effect of this impulse in ancient society. First a body of consanguinei grows into a gens; after a while, neighboring gentes of the same stock-language form a tribe; then neighboring tribes, as some of the Iroquois and Aztecs, form a confederacy. At this point the development of the American Indians was arrested by the coming of the whites. "A coalescence of tribes into a nation had not occurred in any case in any part of America," says the great authority.[35] But we can easily understand what would have occurred had the Indians been left to themselves. They would have passed out of the nomadic state into settlements of fixed abodes, local and geographical political divisions evolving from the old gentes and tribes, the contiguous ones often uniting. History furnishes many examples of neighboring communities coalescing into nations. One of the most remarkable of all is the environment which has constrained peoples of four different languages to coalesce into the little Swiss nation. Turning away from prehistoric times and also ancient history, let the student re-enforce the case of the Swiss, just alluded to, with the modern nation-making in Italy and Germany. These few of the many instances which can be given show how and what sorts of adjacent communities are prone to co-operate or combine for a common purpose, and how such combination develops at last an irresistible proneness to national union. Drops of liquid in proximity to one another on a plane may long maintain each their independent forms; but bring them into actual contact, and presto! all the
