In assuming her station among the civilized nations of the earth it would seem that our country had contracted the engagement to contribute her share of mind, of labor, and of expense to the improvement of those parts of knowledge which lie beyond the reach of individual acquisition, and particularly to geographical and astronomical science. Looking back to the history only of the half century since the declaration of our independence, and observing the generous emulation with which the Governments of France, Great Britain, and Russia have devoted the genius, the intelligence, the treasures of their respective nations to the common improvement of the species in these branches of science, is it not incumbent upon us to inquire whether we are not bound by obligations of a high and honorable character to contribute our portion of energy and exertion to the common stock? The voyages of discovery prosecuted in the course of that time at the expense of those nations have not only redounded to their glory, but to the improvement of human knowledge. We have been partakers of that improvement and owe for it a sacred debt, not only of gratitude, but of equal or proportional exertion in the same common cause. Of the cost of these undertakings, if the mere expenditures of outfit, equipment, and completion of the expeditions were to be considered the only charges, it would be unworthy of a great and generous nation to take a second thought. One hundred expeditions of circumnavigation like those of Cook and La Pérouse would not burden the exchequer of the nation fitting them out so much as the ways and means of defraying a single campaign in war. But if we take into the account the lives of those benefactors of mankind of which their services in the cause of their species were the purchase, how shall the cost of those heroic enterprises be estimated, and what compensation can be made to them or to their countries for them? Is it not by bearing them in affectionate remembrance? Is it not still more by imitating their example--by enabling countrymen of our own to pursue the same career and to hazard their lives in the same cause?
