 My dear friend,


 It is with much satisfaction that
 I introduce to you my esteemed friend,
 Mr. Joseph B. Hume, who proposes to
 spend a month or two in America.


 Mr. Hume will devote a part of this
 time to travelling in the Union, & I refer
 him to you, & to our mutual friend
 Dr. Gray, for such guidance as your
 judgemen & experience may suggest in
 furtherance of his desire to see what
 is most interesting in the natural scenery
 of the Country. The unbroken forest,
 in its magnificence, may now be most
 conveniently seen in Maine, I have
 imagined, & the mountains easiest of
 access-- the Alleghanies & White Mountains.
