The western half of the Mississippi Valley has far outstripped us in material development. Nevertheless, considering the conditions of isolation under which the people of Oregon have labored they can be justly proud of the progress that has been made here in all lines of endeavor. Saint Louis will be justified in vaunting in 1904 the achievements and results of a century of development in the region of which she is the metropolis; but Portland, as the metropolis of the Pacific Northwest, would have been culpably derelict if she had not undertaken an observance of the centennial of the Lewis and Clark expedition that shall emphasize to the nation and to the world the significance of the occupation of the Pacific coast by the American people, and to foster the aspirations of one of the most favored sections on the face of the earth. The basis of our claim to a national recognition of our anniversary is something more solid than the fact that we have added what we have to the material strength of the nation. The secret of the unparalleled effort that Oregon proposes to make for the observance of the Lewis and Clark centennial lies deeper than a mere feeling of exultation over material development and the hope of advertising our resources to the world. The Lewis and Clark Centennial Exposition has clearly two unique and complementary missions. It should bring fully into the national consciousness the historic services through which this nation attained an outlook upon the Pacific comparable with that on the Atlantic, and the significance of this to the future of the American people. It should address itself to the peculiar problems of progress on this coast and thus mark an epoch in the added impetus, the better organization, and the higher aims it gives us as a people; rightly planned it would be an exposition of patriotic national services and of the problems of largest social progress--an exposition of western history and western problems.
