40. PORTLAND, OREGON. Portland, the centre of trade and population of Oregon, is situated on the Willamette River, twelve miles above the Columbia, and, although about a hundred miles from the ocean, is practically a seaport town, as these rivers are navigable for ocean steamers and large ships as far up as Portland. This young, bustling town is the commercial and geographical centre of a grand territory, whose resources are vast and varied; timber, minerals, arable lands, etc., etc., and this too in a state where there has never been a failure in crops.
