1860s, Our Composite Nationality (1869)
Context: The next objection to the Chinese is that he cannot be induced to swear by the Bible. This is to me one of his best recommendations. The American people will swear by any thing in the heaven above or the earth beneath. We are a nation of swearers. We swear by a book whose most authoritative command is to swear not at all. It is not of so much importance what a man swears by, as what he swears to, and if the Chinaman is so true to his convictions that he cannot be tempted or even coerced into so popular a custom as swearing by the Bible, he gives good evidence of his integrity and of his veracity. Let the Chinaman come; he will help to augment the national wealth; he will help to develop our boundless resources; he will help to pay off our national debt; he will help to lighten the burden of our national taxation; he will give us the benefit of his skill as manufacturer and as a tiller of the soil, in which he is unsurpassed.

Letter http://teachingamericanhistory.org/library/index.asp?document=296 to Gilbert du Motier, marquis de Lafayette (1 February 1784)
1780s
Context: I am become a private citizen on the banks of the Potomac, and under the shadow of my own Vine and my own Fig-tree, free from the bustle of a camp and the busy scenes of public life, I am solacing myself with those tranquil enjoyments, of which the Soldier who is ever in pursuit of fame, the Statesman whose watchful days and sleepless nights are spent in devising schemes to promote the welfare of his own, perhaps the ruin of other countries, as if this globe was insufficient for us all, and the Courtier who is always watching the countenance of his Prince, in hopes of catching a gracious smile, can have very little conception. I am not only retired from all public employments, but I am retiring within myself; and shall be able to view the solitary walk, and tread the paths of private life with heartfelt satisfaction. Envious of none, I am determined to be pleased with all; and this my dear friend, being the order for my march, I will move gently down the stream of life, until I sleep with my Fathers.
