Such liberality was the more conspicuous by contrast with the petty rancour of his defeated rival, who not only refused to perform the customary courtesy of welcoming his successor at the White House, but spent his last hours there appointing Federalists feverishly to public offices solely in order to compel Jefferson to choose between the humiliation of retaining such servants and the odium of dismissing them. The new President very rightly refused to recognize nominations so made, and this has been seized upon by his detractors to hold him up as the real author of what was afterwards called "the Spoils System." It would be far more just to place that responsibility upon Adams. The most important event of Jefferson's first administration was the Louisiana Purchase. The colony of Louisiana at the mouth of the Mississippi, with its vast _hinterland_ stretching into the heart of the American continent, had, as we have seen, passed in 1762 from French into Spanish hands. Its acquisition by the United States had been an old project of Jefferson's. When Secretary of State under Washington, he had mooted it when settling with the Spanish Government the question of the navigation of the Mississippi. As President he revived it; but before negotiations could proceed far the whole situation was changed by the retrocession of Louisiana to France as part of the terms dictated by Napoleon to a Spain which had fallen completely under his control. The United States could not, in any case, have regarded the transfer without uneasiness, and to all schemes of purchase it seemed a death-blow, for it was believed that the French Emperor had set his heart upon the resurrection of French Colonial power in America. But Jefferson was an excellent diplomatist, at once conciliatory and unyielding: he played his cards shrewdly, and events helped him. The Peace of Amiens was broken, and, after a very brief respite, England and France were again at war. Napoleon's sagacity saw clearly enough that he could not hope to hold and develop his new colony in the face of a hostile power which was his master on the sea. It would suit his immediate purpose better to replenish his treasury with good American dollars which might soon be urgently needed. He became, therefore, as willing to sell as Jefferson was to buy, and between two men of such excellent sense a satisfactory bargain was soon struck. The colony of Louisiana and all the undeveloped country which lay behind it became the inheritance of the American Federation.
