Dear Belle:
Confound me if I wouldn’t eat up half a dozen of you small girls if I just had the merest shadow of a chance this morning. Here I am, now, about 3 weeks out from Keokuk, and 2 from St. Louis, and yet I have not heard a word from you—and may not, possibly, for 2 or 3 more weeks, as we shall go no further up the river at present, but turn back from here and go to New Orleans.

June 27? Wednesday – Sam wrote brother Orion while on the City of Memphis (surviving fragments here):

What is a government without energy? And what is a man without energy? Nothing—nothing at all. What is the grandest thing in “Paradise Lost”—the Arch-Fiend’s terrible energy! What was the greatest feature in Napoleon’s character? His unconquerable energy! Sum all the gifts that man is endowed with, and we give our greatest share of admiration to his energy. And to-day, if I were a heathen, I would rear a statue to Energy, and fall down and worship it!
