The squatters whom I saw in my walk around the city of Paris, inhabiting what was the military zone with their portable houses, or in their dilapidated shacks, had better shelter than they who first invaded the zone beyond the mountain walls that were the natural western fortifications of the Atlantic colonies.
But though many of those western wilderness immigrants were "poor pilgrims" and for a time squatters (as the immediately extramural population of Paris), they were recruited from the sturdiest stock on the Atlantic side of the fortifications. Some went, to be sure, who had failed in the old place, but were ready to make new hazard; some wanted greater freedom than the more highly socialized and conventionalized life within the fortifications would permit; some longed for adventure; some sought a fortune or competency perhaps impossible in the old settlements; some had only the inherited promptings of the nomad savage in them, and kept ever moving on, making their nameless graves out in the gloom of the forest or upon the silent plains.
It was indeed a motley procession, the by-product of the more or less conservative, sometimes politically or religiously intolerant, aristocratic tide-water settlements. Yet do not make the mistake of thinking that it was slag or refuse humanity, such as camps in the narrow zone around the gates of Paris. It is rather like an industrial by-product that has needed some slight change or adaptation to make it more valuable to society than the original product upon which the manufacturers had kept their attention fixed—or, at any rate, to make the margin of profit in the whole industry greater. Out of once discarded, seemingly valueless matter have come our coal-tar products: saccharine many times sweeter than sugar, colors unknown to the old dyers, perfumes as fragrant as those distilled from flowers, medicines potent to allay fevers. Up in the woods of Canada last summer I found a chemist trying to do with the wood waste what Remsen and Perkin and others have done with coal waste, and I cannot resist the suggestion of my metaphor that there in the forest valleys beyond the Alleghanies the elements and conditions were found to convert this Atlantic by-product, unpromising outwardly, into the substance of a new and precious civilization.
This overmountain procession came chiefly up the watercourses of the south and middle States. Prior to 1830 the mass of pioneer colonists in most of the Mississippi Valley had been contributed by the up-country of the south. The dominant strain in those earlier comers, as President Roosevelt reminds us, was Scotch-Irish, a "race doubly-twisted in the making, flung from island to island and toughened by exile"—a race of frontiersmen than whom a "better never appeared"—a race which was as "steel welded into the iron of an axe." They form the kernel of the "distinctively and intensely American stock who were the pioneers of the axe and the rifle, succeeding the French pioneers of the sword and the bateaux."
What I have just said of them, these Scotch-Irish, is in quotation, for as I have already intimated, my own ancestry is of that double-twisting; and since the time when my first American ancestor settled as the first permanent minister beyond the mountains, following the paths of the French priests in their missions and became a member of a presbytery extending from the mountains to the setting sun, until my last collateral ancestor living among the Indians helped survey the range lines of new States and finally marked the boundaries of the last farms in the passes of the Rockies, that ancestry has followed the frontier westward from where Céloron planted the emblems of French possession along the Ohio to where Chevalier la Vérendrye looked upon the snowy and impassable peaks of the Rockies.
The immigrants to America of that stock had, many of them, at once on reaching the new land found the foot-hills of mountains, chiefly in Pennsylvania. Here they settled, gradually pushing their way southward in the troughs of the mountain streams and making finally a "broad belt from north to south, a shield of sinewy men thrust in between the people of the seaboard and the red warriors of the wilderness," the same men who declared for American independence in North Carolina before any others, even before the men of Massachusetts. With this stock there went over the mountain men of other origins, of course, English, French Huguenots, Germans, Hollanders, Swedes; but the Scotch-Irish were the core of the new life, which in "iron surroundings" became strongly homogeneous—"yet different from the rest of the world—even the world of America, and infinitely more the world of Europe."
In the north the great rivers lay across the tedious paths that ran with the lines of latitude. And so it was partly for physiographic reasons that the first far-stretching expansions of the New England settlements were not toward this great western wilderness but northward along the narrower valleys. It was not until the migration had filled the meagre limits and capacities of these smaller valleys and had carried school-houses and churches and town halls well up granite hillsides, that the western exodus came, to leave those hillside homes and institutional shelters as shells found far from a receding sea, empty or habited by a new species of immigrant. [Footnote: In one of those far northern valleys which I know best there was a school, before the exodus, of some seventy pupils, gathered from the farmers' families of the neighborhood. Now there are not a half-dozen pupils, and they are carried to a neighboring district.] Farms were abandoned for the fertile fields of the far west, from which wheat can be imported for less than the cost of raising it on the sterile hills and in the short-summered valleys. New England had once claimed a fraction of the great west, as, indeed, had most of the other seaboard colonies. But these claims were surrendered to the general government, as we shall see later, "for the common good," and so her migrants had none other than that instinct which follows lines of latitude to keep them practically within the zone of her relinquished claims. Over into New York, New Jersey, and Pennsylvania her children overflowed till a map of these States in 1820, colored to show the origin and character of their various communities, made practically all of western New York, a part of New Jersey and the northern third of Pennsylvania, an expanded New England. Meanwhile the hardiest joined the transmontane migration, and in the decade after the opening of the Erie Canal (1830-40) the whole northern edge of the valley takes color of New England conquest.
So the first peopling was a mingling of the children of the first strugglers with a raw savage continent; men already schooled in adversity, already acquainted with some of the frontier problems—civilization's most highly individualized, least socialized material, the wheat of the new world's first winnowing.
What is particularly to be observed is that men of the north and the south, as far apart as Carolina and Massachusetts, came together beyond the mountains in the united building of commonwealths; for over those mountains the rivers all ran toward the Mississippi, which tied the interests of all together.
There was no north-and-south line then. The men of the valley were all westerners, "men of the western world"; not yet very strong as nationalists, that is, as men of the United States. "Men of the western waters" they also called themselves, for they shunned the uplands and kept near the streams by which or along which they had come into the wilderness and from which they drank. Men of the axe they were, too, in that first occupancy, never venturing far from the trees that gave them both roof and fuel. It was later, as we have seen, that the men of the plough came where the men of the axe had cleared the way.
