The English edition of The Gilded Age, published by George Routledge and Sons, was typeset from proofsheets of the American edition (27 July 73 to Bliss, n. 2click to open link) and illustrated with duplicate electrotypes (“casts”) of the engravings. It included fewer than half the illustrations prepared for the American edition, however. All of the full-page engravings were omitted (evidently because they were too large for the English-edition page format), and as the book progressed, more and more of the small ones were absent as well, so that the third volume contained only three. Presumably the engravings for the last third of the book were completed too late for inclusion in the English edition.

Bliss’s American Publishing Company issued Miller’s book as Unwritten History: Life amongst the Modocs (reversing the title and subtitle of the English edition) in late October 1874. In March 1874 Clemens told Thomas Bailey Aldrich: “Bliss had contracted to pay me 10 p.c. on my next book (contract made 18 months ago) so I made him pay that on Roughing Gilded Age. He paid 7½ p.c. on Roughing It & 5 p.c. on Innocents Abroad. I only made him pay 7½ on Joaquin Miller’s Modoc book, because I don’t think Miller much of a card in America” (24 Mar 74, MH-H, in MTLP , 81). Clemens alluded to the contract signed on 22 June 1872: see 11 June 72 to Sutro, n. 1click to open link, and Contract with American Publishing Company, 22 June 1872click to open link.
