EXAMPLE
“…Mr. Emerson, writing to his friend Carlyle, August 6, 1838, thanking him for his “friendliest seeking of friends for the poor oration” (“The American Scholar”) says: I have written and read a kind of sermon to the Senior Class of our Cambridge Theological School a fortnight ago; and an address to the Literary Societies of Dartmouth College, for though I hate American pleniloquence, I cannot easily say No to young men who bid me speak also. … The first, I hear, is very offensive. I will now try to hold my tongue till next winter…”
