Of the governing conditions of the West, two stand out as of especial importance to history.

One was the presence of unsubdued and hostile Indian tribes. Ever since that extraordinary man, Daniel Boon (whose strange career would make an epic for which there is no room in this book), crossed the Alleghanies a decade before the beginning of the Revolution and made an opening for the white race into the rich valleys of Kentucky, the history of the western frontier of European culture had been a cycle of Indian wars. The native race had not yet been either tamed or corrupted by civilization. Powerful chiefs still ruled great territories as independent potentates, and made peace and war with the white men on equal terms. From such a condition it followed that courage and skill in arms were in the West not merely virtues and accomplishments to be admired, but necessities which a man must acquire or perish. The Westerner was born a fighter, trained as a fighter, and the fighting instinct was ever dominant in him. So also was the instinct of loyalty to his fellow-citizens, a desperate, necessary loyalty as to comrades in a besieged city—as, indeed, they often were.

The other condition was the product partly of natural circumstances and partly of that wise stroke of statesmanship which had pledged the new lands in trust to the whole Confederacy. The Westerner was American—perhaps he was the first absolutely instinctive American. The older States looked with much pride to a long historical record which stretched back far beyond the Union into colonial times. The Massachusetts man would still boast of the Pilgrim Fathers. The Virginian still spoke lovingly of the "Old Plantation." But Kentucky and Tennessee, Ohio and Indiana were children of the Union. They had grown to statehood within it, and they had no memories outside it. They were peopled from all the old States, and the pioneers who peopled them were hammered into an intense and instinctive homogeneity by the constant need of fighting together against savage nature and savage man. Thus, while in the older settlements one man was conscious above all things that he was a New Englander, and another that he was a Carolinian, the Western pioneer was primarily conscious that he was a white man and not a Red Indian, nay, often that he was a man and not a grizzly bear. Hence grew up in the West that sense of national unity which was to be the inspiration of so many celebrated Westerners of widely different types and opinions, of Clay, of Jackson, of Stephen Douglas, and of Abraham Lincoln.

But this was not to take place until the loyalty of the West had first been tried by a strange and sinister temptation.

Aaron Burr had been elected Vice-President coincidently with Jefferson's election as President; but his ambition was far from satisfied. He was determined to make another bid for the higher place, and as a preliminary he put himself forward as candidate for the Governorship of New York State. It was as favourable ground as he could find to try the issue between himself and the President, for New York had been the centre of his activities while he was still an official Democrat, and her favour had given him his original position in the party. But he could not hope to succeed without the backing of those Federalist malcontents who had nearly made him President in 1800. To conciliate them he bent all his energies and talents, and was again on the point of success when Hamilton, who also belonged to New York State, again crossed his path. Hamilton urged all the Federalists whom he could influence to have nothing to do with Burr, and, probably as a result of his active intervention, Burr was defeated.

Burr resolved that Hamilton must be prevented from thwarting him in the future, and he deliberately chose a simple method of removing him. He had the advantage of being a crack shot. He forced a private quarrel on Hamilton, challenged him to a duel, and killed him.

He can hardly have calculated the effect of his action: it shocked the whole nation, which had not loved Hamilton, but knew him for a better man than Burr. Duelling, indeed, was then customary among gentlemen in the United States, as it is to-day throughout the greater part of the civilized world; but it was very rightly felt that the machinery which was provided for the vindication of outraged honour under extreme provocation was never meant to enable one man, under certain forms, to kill another merely because he found his continued existence personally inconvenient. That was what Burr had done; and morally it was undoubtedly murder. Throughout the whole East Burr became a man marked with the brand of Cain. He soon perceived it, but his audacity would not accept defeat. He turned to the West, and initiated a daring conspiracy which, as he hoped, would make him, if not President of the United States, at least President of something.

What Burr's plan, as his own mind conceived it, really was it is extremely difficult to say; for he gave not only different but directly opposite accounts to the various parties whom he endeavoured to engage in it. To the British Ambassador, whom he approached, he represented it as a plan for the dismemberment of the Republic from which England had everything to gain. Louisiana was to secede, carrying the whole West with her, and the new Confederacy was to become the ally of the Mother Country. For the Spanish Ambassador he had another story. Spain was to recover predominant influence in Louisiana by detaching it from the American Republic, and recognizing it as an independent State. To the French-Americans of Louisiana he promised complete independence of both America and Spain. To the Westerners, whom he tried to seduce, exactly the opposite colour was given to the scheme. It was represented as a design to provoke a war with Spain by the invasion and conquest of Mexico; and only if the Federal Government refused to support the filibusters was the West to secede. Even this hint of hypothetical secession was only whispered to those whom it might attract. To others all thought of disunion was disclaimed; and yet another complexion was put on the plot. The West was merely to make legitimate preparations for the invasion of Mexico and Florida in the event of certain disputes then pending with Spain resulting in war. It was apparently in this form that the design was half disclosed to the most influential citizen and commander of the militia in the newly created State of Tennessee, Andrew Jackson, the same that we saw as a mere school-boy riding and fighting at Hanging Rock.

Jackson had met Burr during the brief period when he was in Congress as representative of his State. He had been entertained by him and liked him, and when Burr visited Tennessee he was received by Jackson with all the hospitality of the West. Jackson was just the man to be interested in a plan for invading Mexico in the event of a Spanish war, and he would probably not have been much shocked—for the West was headstrong, used to free fighting, and not nice on points of international law—at the idea of helping on a war for the purpose. But he loved the Union as he loved his own life. Burr said nothing to him of his separatist schemes. When later he heard rumours of them, he wrote peremptorily to Burr for an explanation. Burr, who, to do him justice, was not the man to shuffle or prevaricate, lied so vigorously and explicitly that Jackson for the moment believed him. Later clearer proof came of his treason, and close on it followed the President's proclamation apprehending him, for Burr had been betrayed by an accomplice to Jefferson. Jackson at once ordered out the militia to seize him, but he had already passed westward out of his control. The Secretary for War, who, as it happened, was a personal enemy of Jackson's, thinking his connection with Burr might be used against him, wrote calling in sinister tone for an account of his conduct. Jackson's reply is so characteristic of the man that it deserves to be quoted. After saying that there was nothing treasonable in Burr's communications to him personally, he adds: "But, sir, when proofs showed him to be a Treator" (spelling was never the future President's strong point), "I would cut his throat with as much pleasure as I would cut yours on equal testimony."

The whole conspiracy fizzled out. Burr could get no help from any of the divergent parties he had attempted to gain. No one would fight for him. His little band of rebels was scattered, and he himself was seized, tried for treason, and acquitted on a technical point. But his dark, tempestuous career was over. Though he lived to an unlovely old age, he appears no more in history.
