Jefferson used this book in connection with his mould board of least resistance. In a letter to Robert Patterson, dated from
Philadelphia, March 30, 1798, Jefferson wrote: “
I am much obliged by your letter of yesterday. tho’ I possess Emerson’s fluxions at home, & it was the book I used at College,
yet it had escaped me that he had treated the question of the best form of a body for removing an obstacle in a single direction.
that of the wedge offered itself so readily as the best, that I did not think of questioning it. nor does it now occur to
me on what principle it can be questioned. if you have Emerson and will be so good as to lend him to me a day or two, I will
be obliged to you . . .
”
On the following day, March 31, he again wrote to Patterson: “
I return you Emerson with thanks. it has suggested a qualification of the expression in my letter, which had supposed the
wedge the form offering least resistance to the rising sod. I did at first, as you do now, consider this mould board as a
twisted plane. but a little reflection convinced me, as it will you, that it is not, and that it would be impossible to twist
a board into that form . . .
