In what now forms the United States, taking the country as a whole, the foes who had to be met and overcome were very much more formidable. The ground had to be not only settled but conquered, sometimes at the expense of the natives, often at the expense of rival European races. As already pointed out the Indians themselves formed one of the main factors in deciding the fate of the continent. They were never able in the end to avert the white conquest, but they could often delay its advance for a long spell of years. The Iroquois, for instance, held their own against all comers for two centuries. Many other tribes stayed for a time the oncoming white flood, or even drove it back; in Maine the settlers were for a hundred years confined to a narrow strip of sea-coast. Against the Spaniards, there were even here and there Indian nations who definitely recovered the ground they had lost.
When the whites first landed, the superiority and, above all, the novelty of their arms gave them a very great advantage. But the Indians soon became accustomed to the new-comers' weapons and style of warfare. By the time the English had consolidated the Atlantic colonies under their rule, the Indians had become what they have remained ever since, the most formidable savage foes ever encountered by colonists of European stock. Relatively to their numbers, they have shown themselves far more to be dreaded than the Zulus or even the Maoris.
Their presence has caused the process of settlement to go on at unequal rates of speed in different places; the flood has been hemmed in at one point, or has been forced to flow round an island of native population at another. Had the Indians been as helpless as the native Australians were, the continent of North America would have had an altogether different history. It would not only have been settled far more rapidly, but also on very different lines. Not only have the red men themselves kept back the settlements, but they have also had a very great effect upon the outcome of the struggles between the different intrusive European peoples. Had the original inhabitants of the Mississippi valley been as numerous and unwarlike as the Aztecs, de Soto would have repeated the work of Cortes, and we would very possibly have been barred out of the greater portion of our present domain. Had it not been for their Indian allies, it would have been impossible for the French to prolong, as they did, their struggle with their much more numerous English neighbors.
The Indians have shrunk back before our advance only after fierce and dogged resistance. They were never numerous in the land, but exactly what their numbers were when the whites first appeared is impossible to tell. Probably an estimate of half a million for those within the limits of the present United States is not far wrong; but in any such calculation there is of necessity a large element of mere rough guess-work. Formerly writers greatly over-estimated their original numbers, counting them by millions. Now it is the fashion to go to the other extreme, and even to maintain that they have not decreased at all. This last is a theory that can only be upheld on the supposition that the whole does not consist of the sum of the parts; for whereas we can check off on our fingers the tribes that have slightly increased, we can enumerate scores that have died out almost before our eyes. Speaking broadly, they have mixed but little with the English (as distinguished from the French and Spanish) invaders. They are driven back, or die out, or retire to their own reservations; but they are not often assimilated. Still, on every frontier, there is always a certain amount of assimilation going on, much more than is commonly admitted;1 and whenever a French or Spanish community has been absorbed by the energetic Americans, a certain amount of Indian blood has been absorbed also. There seems to be a chance that in one part of our country, the Indian territory, the Indians, who are continually advancing in civilization, will remain as the ground element of the population, like the Creoles in Louisiana, or the Mexicans in New Mexico.
The Americans when they became a nation continued even more successfully the work which they had begun as citizens of the several English colonies. At the outbreak of the Revolution they still all dwelt on the seaboard, either on the coast itself or along the banks of the streams flowing into the Atlantic. When the fight at Lexington took place they had no settlements beyond the mountain chain on our western border. It had taken them over a century and a half to spread from the Atlantic to the Alleghanies. In the next three quarters of a century they spread from the Alleghanies to the Pacific. In doing this they not only dispossessed the Indian tribes, but they also won the land from its European owners. Britain had to yield the territory between the Ohio and the Great Lakes. By a purchase, of which we frankly announced that the alternative would be war, we acquired from France the vast, ill-defined region known as Louisiana. From the Spaniards, or from their descendants, we won the lands of Florida, Texas, New Mexico, and California.
All these lands were conquered after we had become a power, independent of every other, and one within our own borders; when we were no longer a loose assemblage of petty seaboard communities, each with only such relationship to its neighbor as was implied in their common subjection to a foreign king and a foreign people. Moreover, it is well always to remember that at the day when we began our career as a nation we already differed from our kinsmen of Britain in blood as well as in name; the word American already had more than a merely geographical signification. Americans belong to the English race only in the sense in which Englishmen belong to the German. The fact that no change of language has accompanied the second wandering of our people, from Britain to America, as it accompanied their first, from Germany to Britain, is due to the further fact that when the second wandering took place the race possessed a fixed literary language, and, thanks to the ease of communication, was kept in touch with the parent stock. The change of blood was probably as great in one case as in the other. The modern Englishman is descended from a Low-Dutch stock, which, when it went to Britain, received into itself an enormous infusion of Celtic, a much smaller infusion of Norse and Danish, and also a certain infusion of Norman-French blood. When this new English stock came to America it mingled with and absorbed into itself immigrants from many European lands, and the process has gone on ever since. It is to be noted that, of the new blood thus acquired, the greatest proportion has come from Dutch and German sources, and the next greatest from Irish, while the Scandinavian element comes third, and the only other of much consequence is French Huguenot. Thus it appears that no new element of importance has been added to the blood. Additions have been made to the elemental race-strains in much the same proportion as these were originally combined.
Some latter-day writers deplore the enormous immigration to our shores as making us a heterogeneous instead of a homogeneous people; but as a matter of fact we are less heterogeneous at the present day than we were at the outbreak of the Revolution. Our blood was as much mixed a century ago as it is now. No State now has a smaller proportion of English blood than New York or Pennsylvania had in 1775. Even in New England, where the English stock was purest, there was a certain French and Irish mixture; in Virginia there were Germans in addition. In the other colonies, taken as a whole, it is not probable that much over half of the blood was English; Dutch, French, German, and Gaelic communities abounded.
But all were being rapidly fused into one people. As the Celt of Cornwall and the Saxon of Wessex are now alike Englishmen, so in 1775 Hollander and Huguenot, whether in New York or South Carolina, had become Americans, undistinguishable from the New Englanders and Virginians, the descendants of the men who followed Cromwell or charged behind Rupert. When the great western movement began we were already a people by ourselves. Moreover, the immense immigration from Europe that has taken place since, had little or no effect on the way in which we extended our boundaries; it only began to be important about the time that we acquired our present limits. These limits would in all probability be what they now are even if we had not received a single European colonist since the Revolution.
Thus the Americans began their work of western conquest
