As the Northern Pacific pushed into the Northwest, and at the same time vigorously occupied itself in filling the gap between the ends of its main line, it came into contact with a combination of Northwestern companies known as the Oregon Railway & Navigation Company, of which Henry Villard was at the time in control. This corporation owned a line of steamboats running on the Willamette and Columbia rivers in Oregon, together with an ocean line connecting Portland and San Francisco.[558] In connection with the water routes a narrow-gauge road had been built up the left bank of the Columbia River to a connection near the mouth of the Snake River with an existing narrow-gauge road to the town of Walla Walla in Southeastern Washington; and this narrow-gauge was being widened, in 1880, to standard. This was the very territory through which the Northern Pacific expected to make its connection with the Pacific coast; and in 1880 it had passed the Rocky Mountains and had reached the confluence of the Columbia and the Snake. On October 20, 1880, a contract was signed between the Northern Pacific and the Oregon Railway & Navigation Companies whereby the former, among other things, consented to a division of territory with the Snake and the Columbia rivers as the dividing-line; in return for which the latter agreed to complete a standard-gauge road within three years from the western end of the Northern Pacific, at the mouth of the Snake River, to Portland, and to grant the Northern Pacific the right, without the obligation, to run its own trains over it at a fixed charge per train mile. It will be remembered that the Northern Pacific was not at this time too easy in its finances, so that it was quite willing to secure connection with the coast without outlay of its own. Soon after the execution of the contract, however, the $40,000,000 loan earlier described was arranged for, and Mr. Villard feared that the road would build its own connection with Portland now that the means seemed to be at hand. To prevent it he conceived no less a plan than that of forming a new company which should purchase and hold a controlling interest in both the Northern Pacific and the Oregon Railway & Navigation Companies.[559] This was done, and the new corporation, known as the Oregon & Transcontinental Company, for a long time played a prominent part in Northern Pacific affairs;[560] aiding it in the construction of the main and branch lines, and time and again advancing money when the road was in straits.[561]
