Mr. Greenhow (p. 248) considers that the distinction which Broughton and Vancouver made "between the upper and lower portion of the Columbia, is entirely destitute of foundation, and at variance with the principles of our whole geographical nomenclature. Inlets and sounds," he continues, "are arms of the sea running up into the land, and their waters, being supplied from the sea, are necessarily salt; the waters of the Columbia are on the contrary generally fresh and palatable within ten miles of the Pacific, the violence and overbearing force of the current being sufficient to prevent the further ingress of the ocean. The question appears at first to be of no consequence: the following extract from Vancouver's Journal will, however, serve to show that the quibble was devised by the British navigators, with the unworthy object of depriving Gray of the merits of his discovery:--'Previously to his (Broughton's) departure, he formally took possession of the river, and the country in its vicinity, in his Britannic Majesty's name, having every reason to believe that the subjects of no other civilised nation or state had ever entered this river before. In this opinion he was confirmed by Mr. Gray's sketch, in which it does not appear that Mr. Gray either saw or ever was within five leagues of its entrance.' This unjust view has been adopted by the British Government and writers, and also, doubtless from inadvertency, by some distinguished authors in the United States. It may, indeed, be considered fortunate for Gray, that by communicating the particulars of his discoveries, as he did, to Quadra, he secured an unimpeachable witness of his claims: had he not done so, the world would probably never have learned that a citizen of the United States was the first to enter the greatest river flowing from America into the Pacific, and to find the only safe harbour on the long line of coast between Port San Francisco and the Strait of Fuca."
Mr. Greenhow may be perfectly justified in disputing the propriety of Lt. Broughton's distinction. The words of the latter are,--"Between the ocean and that which should properly be considered the entrance of the river, is a space from three to seven miles wide, intricate to navigate on account of the shoals that extend nearly from side to side, and it ought rather to be considered as _a sound_ than as constituting a part of the river, since the entrance into the river, which they reached about dark, was found not to be more than half a mile wide, formed by the contracting shores of the sound." It may fairly be admitted that the ordinary use of the terms "sound," or "inlet," warrants the verbal criticism of Mr. Greenhow, and that they are more usually employed to distinguish arms of the sea where there is no fresh water, or tideways outside the bars of rivers. Lieutenant Broughton, if we may judge from the context would have been more correct had he used the term "estuary" instead of "sound," for, "in common understanding," as Lord Stowell has observed, "the embouchure or mouth of a river is that spot where the river enters the open space to which the sea flows, and where the points of the coast project no further." (Twee Gebroeden, 3 Robinson's Reports, p. 34.) At the same time, after a careful perusal of Vancouver's journal, a protest must be entered against any reader of that work, particularly against one who occupies the position which Mr. Greenhow fills, attributing such motives to the British navigator, or insinuating such a probability as that Gray's discovery would have been suppressed by Vancouver, had not Gray fortunately secured Quadra as an unimpeachable witness to it. Mr. Greenhow's jealousy for the fame of his countryman may be excusable up to a certain point, but when he states that Vancouver "did not hesitate to adopt unworthy means to deprive the Americans of the reputation which they had justly earned by their labours in exploring, and to blacken their characters as individuals," he has allowed an unreasonable sensitiveness to hurry him into the commission of the very fault which he censures in others, and has laid himself open to the identical charge, mutatis mutandis, which he has set up against Vancouver.
