August 5 Thursday – At Niagara Falls, NY. Sometime during the 3 day stay Jervis Langdon and Sam made a side trip to Buffalo, where Jervis likely visited the branch of his coal company at 221 Main Street, as well as a waterfront coal-yard operation. The pair also searched records in the Buffalo Express office to “confirm the soundness of their upcoming investment.” A few days later (Aug. 14), Twain complained about ‘the bore of wading through the books & getting up balance sheets’” [Reigstad 60-61]. Note: the Aug. 14 letter was to Mary Mason and Abel W. Fairbanks: “As soon as Mr. Langdon saw the books of the concern he was satisfied” [MTL 3: 298].
