According to Scharnhorst ((The Middle Years pg 430), they left Baltimore early Monday morning (after midnight).  Following Day By Day, they must have traveled to Hartford and Simsbury respectively. From New Haven, Twain would continue to Hartford and Cable would take the New Haven and Northampton to Simsbury.  Later that day the Clemens family drove north a few hours to Simsbury. Sam and Cable would take the New Haven and Northampton to Westfield, then the Boston and Albany to  Adams, Mass., on the western side of the state. Sam wrote at 6:30 PM from Adams, Mass. to Livy, that he’d enjoyed the few hours ride to Simsbury with her and the children. His hoarseness had disappeared, he hadn’t had a nap and hoped Livy could cheer her mother up about Charles Langdon, who was in poor health [MTP]. 

In the evening, Sam and Cable gave a reading in Town Hall, Adams, Mass.
