lightened nations are equally interested, has a right to expect the 
good-will and good offices of the whole civilized world. Should our 
country, therefore, be unhappily involved in war during your absence, 
you will refrain from all acts of hostility whatever, as it is confidently 
believed none will be committed against you. So far from this being 
the case, it is not to be doubted that even hostile nations will respect 
your purposes, and afford every facility to their accomplishment. 
Finally, you will recollect, that though you may frequently be 
carried beyond the sphere of social life, and the restraints of law, 
yet that the obligations of justice and humanity are always and every 
where equally imperative in our intercourse with men, and most 
especially savages ; that we seek them, not they us ; and that if we 
expect to derive advantages from the intercourse, we should endea- 
vour to confer benefits in return. 
Although the primary object of the Expedition is the promotion of 
the great interests of commerce and navigation, yet you will take all 
occasions, not incompatible with the great purposes of your under- 
taking, to extend the bounds of science, and promote the acquisition 
of knowledge. For the more successful attainment of these, a corps 
of scientific gentlemen, consisting of the following persons, will 
accompany the Expedition, and are placed under your direction. 
Mr. Hale, Philologist. 
Mr. Pickering, 7 Naturalists

The hydrography and geography of the various seas and coun- 
tries you may visit in the route pointed out to you in the preceding 
instructions, will occupy your special attention; and all the researches 
connected with them, as well as with astronomy, terrestrial magnet- 
ism, and meteorology, are confided exclusively to the officers of the 
navy, on whose zeal and talents the Department confidently relies 
for such results as will enable future navigators to pass over the track 
traversed by your vessels, without fear and without danger.
