... Nothing more aptly describes the character of our Republic than the solar system, launched into space by the hand of the Creator, where the central sun is the great power around which revolve all the planets in their appointed orbits. But while the sun holds in the grasp of its attractive power the whole system, and imparts its light and heat to all, yet each individual planet is under the sway of laws peculiar to itself. Under the sway of terrestrial laws, winds blow, waters flow, and all the tenantries of the planet live and move. So, sir, the States move on in their orbits of duty and obedience, bound to the central government by this Constitution, which is their supreme law; while each State is making laws and regulations of its own, developing its own energies, maintaining its own industries, managing its local affairs in its own way, subject only to the supreme but beneficent control of the Union. When State-rights ran mad, put on the form of secession, and attempted to drag the States out of the Union, we saw the grand lesson, taught in all the battles of the late war, that a State could no more be hurled from the Union, without ruin to the nation, than could a planet be thrown from its orbit without dragging after it, to chaos and ruin, the whole solar universe. In 1865 we had a debt of two billions seven hundred and seventy-two millions of dollars upon our hands, the debt accumulated from the great results of the war; we were compelled to pay from that debt one hundred and fifty-one millions of dollars in coin a year as interest, and that was a dreadful annual burden. In the year after the war ended, we paid five hundred and ninety millions of dollars over our counter in settling the business of the war and maintaining the ordinary expenses of the government. These tremendous burdens it seemed for a time we could not carry, and there were wicked men, and despairing men, and men who said we ought not to try to carry the burdens; but the brave nation said, This burden is the price of our country's life, all through it there is the price of blood and the price of liberty, and, therefore, we will bow our knees to the burden, we will carry it upon the stalwart shoulders of the nation. [Letter to Professor Demmon December 16, 1871.] ... Since I entered public life, I have constantly aimed to find a little time to keep alive the spirit of my classical studies, and to resist that constant tendency, which all public men feel, to grow rusty in literary studies, and particularly in the classical studies. I have thought it better to select some one line of classical reading, and, if possible, do a little work on it each day. For this winter I am determined to review such parts of the Odes of Horace as I may be able to reach. And, as preliminary to that work, I have begun by reading up the bibliography of Horace.
