Jefferson's
Instructions to Meriwether Lewis
jUNE
20, 1803
"To Meriwether Lewis,
esquire, Captain of the 1st regiment of infantry of the United States of
America.
"Your situation as
Secretary of the President of the United States has made you acquainted with
the objects of my confidential message of Jan. 18, 1803, to the legislature.
You have seen the act they passed, which, tho' expressed in general terms, was
meant to sanction those objects, and you are appointed to carry them into
execution.
"Instruments for
ascertaining by celestial observations the geography of the country thro' which
you will pass, have been already provided. Light articles for barter, &
presents among the Indians, arms for your attendants, say for from 10 to 12
men, boats, tents, & other travelling apparatus, with ammunition, medicine,
surgical instruments & provision you will have prepared with such aids as
the Secretary at War can yield in his department; & from him also you will
receive authority to engage among our troops, by voluntary agreement, the
number of attendants above mentioned, over whom you, as their commanding
officer are invested with all the powers the laws give in such a case.
"As your movements while
within the limits of the U.S. will be better directed by occasional
communications, adapted to circumstances as they arise, they will not be
noticed here. What follows will respect your proceedings after your departure
from the U.S.
"Your mission has
been communicated to the Ministers here from France, Spain, & Great
Britain, and through them to their governments: and such assurances given them
as to it's objects as we trust will satisfy them. The country of Louisiana
having been ceded by Spain to France, the passport you have from the Minister
of France, the representative of the present sovereign of the country, will be
a protection with all its subjects: and that from the Minister of England will
entitle you to the friendly aid of any traders of that allegiance with whom you
may happen to meet.
"The object of your mission
is to explore the Missouri river, & such principal stream of it, as, by
it's course & communication with the water of the Pacific ocean may offer
the most direct & practicable water communication across this continent,
for the purposes of commerce.
"Beginning at the mouth of
the Missouri, you will take observations of latitude and longitude at all
remarkable points on the river, & especially at the mouths of rivers, at
rapids, at islands & other places & objects distinguished by such
natural marks & characters of a durable kind, as that they may with
certainty be recognized hereafter. The courses of the river between these
points of observation may be supplied by the compass, the log-line & by
time, corrected by the observations themselves. The variations of the compass
too, in different places should be noticed.
"The interesting points of
the portage between the heads of the Missouri & the water offering the best
communication with the Pacific ocean should be fixed by observation, & the
course of that water to the ocean, in the same manner as that of the Missouri.
"Your observations are to
be taken with great pains & accuracy to be entered distinctly, &
intelligibly for others as well as yourself, to comprehend all the elements
necessary, with the aid of the usual tables to fix the latitude & longitude
of the places at which they were taken, & are to be rendered to the war
office, for the purpose of having the calculations made concurrently by proper
persons within the U.S. Several copies of these as well as of your other notes,
should be made at leisure times, & put into the care of the most
trustworthy of your attendants, to guard by multiplying them against the accidental
losses to which they will be exposed. A further guard would be that one of
these copies be written on the paper of the birch, as less liable to injury
from damp than common paper.
"The commerce which may be
carried on with the people inhabiting the line you will pursue, renders a
knolege of these people important. You will therefore endeavor to make yourself
acquainted, as far as a diligent pursuit of your journey shall admit,
with the names of the nations & their numbers;
the extent & limits of their possessions;
their relations with other tribes or nations;
their language, traditions, monuments;
their ordinary occupations in agriculture,
fishing, hunting, war,
arts, & the implements for these;
their food, clothing, & domestic
accommodations;
the diseases prevalent among them, & the
remedies they use;
moral and physical circumstance which
distinguish them
from the tribes they know;
peculiarities in their laws, customs &
dispositions;
and articles of commerce they may need or
furnish, & to what extent.
"And considering the
interest which every nation has in extending & strengthening the authority
of reason & justice among the people around them, it will be useful to
acquire what knolege you can of the state of morality, religion &
information among them, as it may better enable those who endeavor to civilize
& instruct them, to adapt their measures to the existing notions &
practises of those on whom they are to operate.
"Other objects worthy of
notice will be
the soil & face of the country, it's growth
& vegetable
productions, especially those not of the U.S.
the animals of the country generally, &
especially those
not known in the U.S. the remains & accounts
of any which
may be deemed rare or extinct;
the mineral productions of every kind; but more
particularly
metals, limestone, pit coal & saltpetre;
salines & mineral waters, noting the temperature
of the last
& such circumstances as may indicate their
character;
volcanic appearances;
climate as characterized by the thermometer, by
the
proportion of rainy, cloudy & clear
days, by lightening, hail,
snow, ice, by the access & recess of frost, by the
winds,
prevailing at different seasons, the dates at which
particular
plants put forth or lose their flowers, or leaf,
times of
appearance of particular birds, reptiles or insects.
"Altho' your route will be
along the channel of the Missouri, yet you will endeavor to inform yourself, by
inquiry, of the character and extent of the country watered by its branches,
& especially on it's Southern side. The North river or Rio Bravo which runs
into the gulph of Mexico, and the North river, or Rio colorado which runs into
the gulph of California, are understood to be the principal streams heading
opposite to the waters of the Missouri, and running Southwardly. Whether the
dividing grounds between the Missouri & them are mountains or flatlands, what
are their distance from the Missouri, the character of the intermediate
country, & the people inhabiting it, are worthy of particular enquiry. The
Northern waters of the Missouri are less to be enquired after, because they
have been ascertained to a considerable degree, and are still in a course of
ascertainment by English traders & travellers. But if you can learn
anything certain of the most Northern source of the Mississippi, & of it's
position relative to the lake of the woods, it will be interesting to us. Some
account too of the path of the Canadian traders from the Mississippi, at the
mouth of the Ouisconsin river, to where it strikes the Missouri, and of the
soil and rivers in it's course, is desirable.
"In all your intercourse
with the natives treat them in the most friendly & conciliatory manner
which their own conduct will admit; allay all jealousies as to the object of
your journey, satisfy them of it's innocence, make them acquainted with the
position, extent, character, peaceable & commercial dispositions of the
U.S., of our wish to be neighborly, friendly & useful to them, & of our
dispositions to a commercial intercourse with them; confer with them on the
points most convenient as mutual emporiums, & the articles of most desirable
interchange for them & us. If a few of their influential chiefs, within
practicable distance, wish to visit us, arrange such a visit with them, and
furnish them with authority to call on our officers, on their entering the U.S.
to have them conveyed to this place at the public expense. If any of them
should wish to have some of their young people brought up with us, & taught
such arts as may be useful to them, we will receive, instruct & take care
of them. Such a mission, whether of influential chiefs, or of young people,
would give some security to your own party. Carry with you some matter of the
kine pox, inform those of them with whom you may be, of it's efficacy as a
preservative from the small pox; and instruct & encourage them in the use
of it. This may be especially done wherever you may winter.
"As it is impossible for us
to foresee in what manner you will be received by those people, whether with
hospitality or hostility, so is it impossible to prescribe the exact degree of
perseverance with which you are to pursue your journey. We value too much the
lives of citizens to offer them to probably destruction. Your numbers will be
sufficient to secure you against the unauthorised opposition of individuals, or
of small parties: but if a superior force, authorised or not authorised, by a
nation, should be arrayed against your further passage, & inflexibly
determined to arrest it, you must decline it's further pursuit, and return. In
the loss of yourselves, we should lose also the information you will have acquired.
By returning safely with that, you may enable us to renew the essay with better
calculated means. To your own discretion therefore must be left the degree of
danger you may risk, & the point at which you should decline, only saying
we wish you to err on the side of your safety, & to bring back your party
safe, even if it be with less information.
"As far up the Missouri as
the white settlements extend, an intercourse will probably be found to exist
between them and the Spanish posts at St. Louis, opposite Cahokia, or Ste.
Genevieve opposite Kaskaskia. From still farther up the river, the traders may
furnish a conveyance for letters. Beyond that you may perhaps be able to engage
Indians to bring letters for the government to Cahokia or Kaskaskia, on promising
that they shall there receive such special compensation as you shall have
stipulated with them. Avail yourself of these means to communicate to us, at
seasonable intervals, a copy of your journal, notes & observations of every
kind, putting into cypher whatever might do injury if betrayed.
"Should you reach the
Pacific ocean, inform yourself of the circumstances which may decide whether
the furs of those parts may not be collected as advantageously at the head of
the Missouri (convenient as is supposed to the waters of the Colorado &
Oregon or Columbia) as at Nootka sound or any other point of that coast; &
that trade be consequently conducted through the Missouri & U.S. more
beneficially than by the circumnavigation now practised.
"On your arrival on that
coast, endeavor to learn if there be any port within your reach frequented by
the sea-vessels of any nation, and to send two of your trusty people back by
sea, in such way as shall appear practicable, with a copy of your notes. And
should you be of opinion that the return of your party by the way they went
will be eminently dangerous, then ship the whole, & return by sea by way of
Cape Horn or the Cape of Good Hope, as you shall be able. As you will be
without money, clothes or provisions, you must endeavor to use the credit of
the U.S. to obtain them; for which purpose open letters of credit shall be
furnished you authorizing you to draw on the Executive of the U.S. or any of
its officers in any part of the world, in which draughts can be disposed of, and
to apply with our recommendations to the consuls, agents, merchants or citizens
of any nation with which we have intercourse, assuring them in our name that
any aids they may furnish you shall be honorably repaid, and on demand. Our
consuls Thomas Howes at Batavia in Java, William Buchanan of the Isles of
France and Bourbon, & John Elmslie at the Cape of Good Hope will be able to
supply your necessities by draughts on us.
"Should you find it safe to
return by the way you go, after sending two of your party round by sea, or with
your whole party, if no conveyance by sea can be found, do so; making such
observations on your return as may serve to supply, correct or confirm those
made on your outward journey.
"In re-entering the U.S.
and reaching a place of safety, discharge any of your attendants who may desire
& deserve it: procuring for them immediate paiment of all arrears of pay
& cloathing which may have incurred since their departure and assure them
that they shall be recommended to the liberality of the legislature for the
grant of a souldier's portion of land each, as proposed in my message to
Congress: & repair yourself with your papers to the seat of government.
"To provide, on the
accident of your death, against anarchy, dispersion & the consequent danger
to your party, and total failure of the enterprise, you are hereby authorised,
by any instrument signed & written in your own hand, to name the person
among them who shall succeed to the command on your decease, & by like
instruments to change the nomination from time to time, as further experience
of the characters accompanying you shall point out superior fitness: and all
the powers & authorities given to yourself are, in the event of your death,
transferred to & vested in the successor so named, with further power to
him, & his successors in like manner to name each his successor, who, on
the death of his predecessor shall be invested with all the powers &
authorities given to yourself.
"Given under my hand at the
city of Washington, this 20th. day of June 1803."
Th:Jefferson, Pr. U.S. of
America.
