August 13 Friday – Sam received a letter from John Slee, agent for the Anthracite Coal Association in Buffalo, informing him that Jervis Langdon’s check was on the way, and that Slee would add another check totaling $12,500. The papers might be exercised that day [MTL 3: 294n2]. Note: Jervis Langdon’s check for $12,500 plus Twain’s $2,500 went toward the down payment with Langdon guaranteeing the balance.
