It is with this view that it might be proper, should you approve the
plan I have submitted to you, to direct, that the reports of the
officers should be transmitted to Captain Douglass, by whom they will be
incorporated with his own observations, and will appear in a form best
calculated to promote the views which you entertain upon the important
subject of the internal geography of our country.
IV.
DETROIT, October 3, 1820.
SIR: On the eve of separating from my associates in our late tour, I owe
it to them and to myself, that I should state to you my opinion
respecting Captain Douglass and Mr. Schoolcraft.
I have found them, upon every occasion, zealous in promoting the
objects of the Expedition, indefatigable in their inquiries and
observations, and never withholding their personal exertions. Ardent in
their pursuit after knowledge, with great attainments in the departments
of literature to which they have respectively devoted themselves, and
with powers which will enable them to explore the whole field of
science, I look forward with confidence to the day when they will assume
distinguished stations among our scientific men, and powerfully aid in
establishing the literary fame of their country.
Should any object of a similar character again require similar talents,
I earnestly recommend their employment. Whoever has the pleasure of
being associated with them, will find how easily profound acquirements
may be united with that urbanity of manners, and those qualities of the
heart, which attach to each other those who have participated in the
fatigues of a long and interesting tour.
Very respectfully, sir,
I have the honor to be
Your obedient servant,
LEWIS CASS.
Hon. JOHN C. CALHOUN, _Secretary of War_.
2. TOPOGRAPHY AND ASTRONOMY.
Topographical materials were collected by Capt. Douglass, U.S.A., for a
map of the northwestern portions of the United States, embracing the
complete circumnavigation of the great lake basins, and accurate
delineations of the sources of the Mississippi, as low down as the
influx of the River Wisconsin. Being provided with instruments from the
Military Academy of West Point, astronomical observations were made at
every practical point over the vast panorama traversed by the
Expedition. A line of some four thousand miles of previously unexplored
country was visited; his notes and memoranda for a topographical memoir
were full and exact; and they were left, I am informed, in a state of
nearly perfect elaboration, accompanied by illustrations, and many
drawings of scenery. Having written to his family recently, for the
astronomical observations, they were transmitted by his son in a letter,
of which the following is an extract:--
