Absorbing as the treaty debate was, it did not prevent other and very weighty legislation. One Act, adopted in the midst of the excitement of the treaty, was peculiarly important, and, although the idea itself was not new, Mr. Gallatin was the first to embody it in law, so far as any single individual can lay claim to that distinction. This Act created the land-system of the United States government; it applied only to lands north-west of the Ohio River, in which the Indian titles had been extinguished, and it provided for laying these out in townships, six miles square, and for selling the land in sections, under certain reservations. This land-system, always a subject of special interest to Mr. Gallatin, and owing its existence primarily to his efforts while a legislator, took afterwards an immense development in his hands while he was Secretary of the Treasury, and, had he been allowed to carry out his schemes, would probably have been made by him the foundation of a magnificent system of internal improvement. Circumstances prevented him from realizing his plan; only the land-system itself and the Cumberland Road remained to testify the breadth and accuracy of his views; but even these were achievements of the highest national importance. Deeply as these two subjects interested him, his permanent and peculiar task was a different one. To Mr. Gallatin finance was an instinct. He knew well, as Mr. Hamilton had equally clearly understood before him, that the heart of the government was the Treasury; like many another man of high financial reputation, he had little talent for money-making, and never was, or cared to be, rich; but he had one great advantage over most Americans of his time, even over Mr. Hamilton and Mr. Jefferson; he was an economist as well as a statesman; he was exact not merely in the details but in the morality of affairs; he held debt in horror; punctilious exactness in avoiding debt was his final axiom in finance; the discharge of debt was his first principle in statesmanship; searching and rigid economy was his invariable demand whether in or out of office, and he made this demand imperative upon himself as upon others.
