One of the especially interesting events in connection with the Nez Perce mission was the acquisition by Mr. Spalding of the first printing-press used west of the Rocky Mountains. This was donated by the church of Rev. H. Bingham at Honolulu in 1839. The indefatigable Spalding, with the assistance of his wife, who had unusual powers as a linguist, began at once reducing the Nez Perce language to a written form and printing in it translations of hymns and portions of the Bible. Some of these first books of the Columbia River are still in existence. The venerable printing-press is in the museum of the Oregon Pioneer Society at Portland. The most dramatic and influential event in connection with the missions of the Columbia, one of the most so in all American history, was Dr. Whitman's mid-winter ride in 1842-43 from Waiilatpu to St. Louis. Dr. Whitman, in common with Jason Lee, soon began to perceive that the Columbia Valley possessed resources and a location which would inevitably make it the seat of a civilised population. The corollary of this was that the mission must conform to the movements of the whites and in time cease to be simply an Indian mission. He perceived another thing. That was the purpose of the Hudson's Bay Company to hold Oregon under English possession and keep it a wilderness for the sake of the fur-trade. The corollary of that was that, if American families could be induced to locate in Oregon, they would in time topple the scale in favour of American ownership. The value of Oregon was then but dimly understood among the Americans. Webster, Benton, and others of the great statesmen are on record in the _Congressional Globe_ with many disparaging remarks upon "that worthless Columbia River country." Whitman watched all signs with anxious eye. Negotiations between England and the United States indicated a probable surrender to the former. The American Board was considering the abandonment of the mission. Looking over the broad field of the future of the American nation with a statesman's vision, Dr. Whitman readily saw that the interests of his country and of Christian civilisation demanded the acquisition of Oregon. Those interests were in jeopardy. He made the great resolution to proceed at once to the "States" with the threefold aim: confer with the officers of the American Board on the retention of the mission, confer with President Tyler, Secretary Webster, and such others of the officers of government as he could see at Washington, and finally help organise and lead back to Oregon an American immigration. His fellow-missionaries strongly opposed his purpose. They felt that it was abandoning the religious aims of the mission to take up political questions. But he declared that he had not expatriated himself by becoming a missionary. Go he would. The undertaking seemed chimerical, even desperate. But Whitman was bold, athletic, persistent, possessing all the qualities of a hero.
