Albert Bigelow Paine,
The Boys' Life of Mark Twain — Chapter 34
(1916)
“ Clemens finally agreed that he would take his family back to America and come back himself within the month. This plan he carried out. Returning to London, he lectured steadily for two months in the big Hanover Square rooms, giving his Roughing It address, and it was only toward the end that his audience showed any sign of diminishing. There is probably no other such a lecture triumph on record. Mark Twain was at the pinnacle of his first glory: thirty-six, in full health, prosperous, sought by the world's greatest, hailed in the highest places almost as a king. ”
