“No question,” Masur says, “politics was on everyone’s mind” as our heroes began their journey. “Jefferson and Madison’s tour through Federalist New England undoubtedly reinforced for them the necessity of taking a firm public stand against what they saw as the heresies of the day. Yet, in the end, politics was not their main purpose.” “Health, recreation, and curiosity,” said Madison, prompted their trip. What else might we expect him to have said?
From then on, each chapter of the book about the journey itself is titled to refer to one of the main matters of interest to Jefferson and Madison as they made their way. Jefferson famously was a man of encyclopedic interests, and Madison, too, could be prompted to take up matters of fascination. While we are prone to think of them now as among the premier politicians in the country’s history, both of them were first substantial farmers, of course, and one of the purposes of their journey was to investigate the problems posed to American agriculture by the Hessian fly.
Masur provides information about the new pest’s appearance in Europe, about Jefferson’s role in spurring the American Philosophical Society to investigate the Hessian fly, about the questions regarding the fly—when it first appeared, whether it grew from egg or worm, the type(s) of wheat it attacked, how it had been successfully fought—to ask people along their route. “Jefferson’s most extensive writing” on the trip, we learn, “was his notes on the Hessian fly.” “They are never in the grain or chaff,” he jotted, likely irked by the British government’s measures to exclude American wheat imports. Though an amateur scientist, Jefferson was a notable one. In his leisure time, he did significant mental work, and Madison was right along with him. Much of their recreation on the trip had practical application.
Masur also describes Jefferson’s relationships with one of his daughters and a slave, as shown on this trip. Rather than a single narrative account, the book presents a timeline with several points of interest along it, at which the author delves into related, sometimes distantly related, matters. The “forging of a friendship” in the book’s title does not exactly capture the book’s content. For example, there are sections on Jefferson’s relationship with his younger daughter and on the slave man he took with him to France, neither of which is related to the older man’s relationship with James Madison.
