The Macedonian has been chosen instead of a sloop of war, on account of the increased accommodations she will afford the scientific corps, a department the President has determined shall be complete in its organization, including the ablest men that can be procured, so that nothing within the whole range of every department of natural history and philosophy shall be omitted. Not only on this account has the frigate been selected, but also for the purpose of a more extended protection of our whalemen and traders; and to impress on the minds of the natives a just conception of our character, power, and policy. The frequent disturbances and massacres committed on our seamen by the natives inhabiting the islands in those distant seas, make this measure the dictate of humanity. We understand also, that to J. N. Reynolds, Esq. the President has given the appointment of Corresponding Secretary to the expedition. Between this gentleman and Captain Jones there is the most friendly feeling and harmony of action. The cordiality they entertain for each other, we trust will be felt by all, whether citizen or officer, who shall be so fortunate as to be connected with the expedition. Thus it will be seen, steps are being taken to remove the reproach of our country alluded to by Mr. Reynolds, and that that gentleman has been appointed to the highest civil situation in the expedition; a station which we know him to be exceedingly well qualified to fill. The liberality of the appropriation for the enterprise, the strong interest taken by our energetic chief magistrate in its organization, the experience and intelligence of the distinguished commander at its head, all promise well for its successful termination. Our most cordial good wishes will accompany the adventure, and we trust that it will prove the germ of a spirit of scientific ambition, which, fostered by legislative patronage and protection, shall build up for us a name in nautical discovery commensurate with our moral, political, and commercial position among the nations of the earth.
