Maclure Quote“The foregoing observations are the result of many former excursions in the United States, and a knowledge lately acquired by crossing the dividing line of the principal formations 15 to 20 different places, from the Hudson to Flint river; as well as from the information of intelligent men, whose situation and experience, make the nature of the place near which they live familiar to them; nor has the information that could be acquired from specimens, when the locality was accurately marked, been neglected, nor the remarks of judicious travelers.”

“ Should this hasty and imperfect sketch
call forth the attention of those possessed of
more talents and industry for the
accurate investigation of this interesting
subject, the views of the author will be fully
accomplished.”
