"The year was 1791, Jefferson, then Secretary of State under George Washington, was embroiled in various political & personal matters. His ideological vision for America, in conflict with the governmental system espoused by Alexander Hamilton, was causing political relationships to crumble & his already strained friendship with John Adams to deteriorate further. Consequently, Jefferson’s month-long “botanizing excursion” through New England with James Madison in June was the subject of much speculation that summer.
"Hamilton & other political adversaries were convinced that this lengthy vacation of two Republican Virginians through Federalist strongholds in the North had secret, ulterior motives. It would seem likely that, as Jefferson historian Merrill Peterson surmised, while the 2 future presidents “bounced along in leisurely fashion, their conversation must have turned occasionally to politics.” Yet, apparently the trip was innocent of intrigue & intended exclusively for, in Madison’s words, “health recreation & curiosity.” This goal was successfully achieved, for both Jefferson’s “periodical” migraines & Madison’s “bilious attacks” vanished in the nearly 4 weeks they spent walking over historic battlefields, studying botanical curiosities, wildlife & insects (including “musketoes” & the Hessian fly), recording observations on climate, the seasons & the appearance of birds, & even boating & fishing in Lake George & Lake Champlain.
What drew this unlikely vacation getaway pair together? Jefferson & Madison were both born into well-established Virginia families, attended prestigious schools, & earned high marks. They shared an interest in industry & government, & each eventually became President Of The United States. They were energetic & ambitious. Both Madison & Jefferson were generally respected by their contemporaries in 1791. They both owned slaves, yet each spoke against the concept of slavery. Madison was realistic & pragmatic. Jefferson was imaginative & creative, he even proposed that the constitution be changed every 19 years. Madison generally did not give his slaves grueling or tedious tasks, reflecting his practical management approach. Jefferson, on the other hand, micro-managed his slaves to do very specific things such as clean his horse so well there was not a spot of dirt on it. Jefferson was very serious, while Madison would often tell jokes. And both seemed to find discovering botanical "curiosities" a relaxing project.
