During the past week I have written the first four chapters of the book, and I tell you 'The Innocents Abroad' will have to get up early to beat it. It will be a book that will jump straight into continental celebrity the first month it is issued.

He prophesied a sale of 90,000 copies during the first twelve months and declared, “I see the capabilities of the subject.”

But further disasters, even then impending, made continued effort impossible; the prospect of the new book for a time became gloomy, the idea of it less inspiring. Other plans presented themselves, and at one time he thought of letting the Galaxy publishers get out a volume of his sketches. In October he wrote Bliss that he was “driveling along tolerably fair on the book, getting off from twelve to twenty pages of manuscript a day.” Bliss naturally discouraged the Galaxy idea, and realizing that the new book might be long delayed, agreed to get out a volume of miscellany sufficiently large and important for subscription sales. He was doubtful of the wisdom of this plan, and when Clemens suddenly proposed a brand-new scheme his publisher very readily agreed to hold back the publication of Sketches indefinitely.

The new book was to be adventures in the diamond mines of South Africa, then newly opened and of wide public interest. Clemens did not propose to visit the mines himself, but to let another man do the traveling, make the notes, and write or tell him the story, after which Clemens would enlarge and elaborate it in his own fashion. His adaptation of the letters of Professor Ford, a year earlier, had convinced him that his plan would work out successfully on a larger scale; he fixed upon his old friend, J. H. Riley, of Washington—[“Riley-Newspaper Correspondent.” See Sketches.]—(earlier of San Francisco), as the proper person to do the traveling. At the end of November he wrote Bliss:

I have put my greedy hands upon the best man in America for my
purpose, and shall start him to the diamond field in South Africa
within a fortnight at my expense... that the book will have a
perfectly beautiful sale.

He suggested that Bliss advance Riley's expense money, the amount to be deducted from the first royalty returns; also he proposed an increased royalty, probably in view of the startling splendor of the new idea. Bliss was duly impressed, and the agreement was finally made on a basis of eight and one-half per cent., with an advance of royalty sufficient to see Riley to South Africa and return.

Clemens had not yet heard from Riley definitely when he wrote his glowing letter to Bliss. He took it for granted that Riley, always an adventurous sort, would go. When Riley wrote him that he felt morally bound to the Alta, of which he was then Washington correspondent, also in certain other directions till the end of the session, Clemens wrote him at great length, detailing his scheme in full and urging him to write instantly to the Alta and others, asking a release on the ground of being offered a rare opportunity to improve his fortunes.

You know right well that I would not have you depart a hair from any obligation for any money. The boundless confidence that I have in you is born of a conviction of your integrity in small as well as in great things. I know plenty of men whose integrity I would trust to here, but not off yonder in Africa.

His proposal, in brief, to Riley was that the latter should make the trip to Africa without expense to himself, collect memoranda, and such diamond mines as might be found lying about handy. Upon his return he was to take up temporary residence in the Clemens household until the book was finished, after which large benefits were to accrue to everybody concerned. In the end Riley obtained a release from his obligations and was off for the diamond mines and fortune.

Poor fellow! He was faithful in his mission, and it is said that he really located a mining claim that would have made him and his independent for all time to come; but returning home with his precious memoranda and the news of good fortune, he accidentally wounded himself with a fork while eating; blood-poisoning set in (they called it cancer then), and he was only able to get home to die. His memoranda were never used, his mining claim was never identified. Certainly, death was closely associated with Mark Twain's fortunes during those earlier days of his married life.
