Typographical errors, or mere blunders of haste, should not, certainly, be expected in a standard work; yet are almost invariably found, particularly in the first edition; and, indeed, seldom or never disappear entirely; almost every teacher, or student, including myself, having noticed, or reported such even in standard text-books. By reference to the preface of my history it will be seen that the work was undertaken with full understanding that a complete, or critical, history of Oregon could not yet be written; but it was thought worth while now to lay the basis of an investigation and ask the patronage of the public. I would, therefore, feel it a most friendly courtesy if any supposedly erroneous matter, whether mere slips, or differences of information or opinion--in the great number of details that it has been attempted to furnish--would be reported to me. I am confident that the work has been begun on a sufficiently broad basis to bear much further elaboration. Any mistakes reported, together with such as may be found by myself, will, if they seem sufficiently numerous and formidable, be collated and published as a page of errata, and the corrected list be furnished each subscriber or purchaser, so far as these may be known. I hope that this may prove a useful line of inquiry, and place the readers somewhat on their own mettle, and thus furnish me matter for notice in a second edition, if this should be produced. Such investigation and criticism would also establish more firmly in public confidence such data as do not prove open to question. H. S. LYMAN. _Astoria, Oregon, May 13, 1903._ THE QUARTERLY OF THE OREGON HISTORICAL SOCIETY. VOLUME IV. JUNE, 1903 NUMBER 2 OREGON AND ITS SHARE IN THE CIVIL WAR.[36] By the Convention of 1818, renewed in 1827, the Oregon Country, comprising a large part of what is now denominated in general terms, the Pacific Northwest, was under the joint occupancy of Great Britain and the United States. The practical evidence of this joint sovereignty on the part of the British, was the sway of the Hudson Bay Company through its network of trading stations and outfitting points for its cohorts of frontiersmen and trappers. Until the advent of the missionary movement from the States, there was little practical evidence of the coordinate sovereignity of the United States.
