The top of the can, which has a small hole pierced in it, is then soldered on, and five hundred tins set on a form are lowered into a huge kettle of boiling water, where they remain until the heat has expelled all the air. Then a Chinaman neatly drops a little solder over each pin-hole, and after another boiling, the object of which is, I believe, to make sure that the cans are hermetically sealed, the process is complete, and the salmon are ready to take a journey longer and more remarkable even than that which their progenitors took when, seized with the curious rage of spawning, they ascended the Columbia, to deposit their eggs in its head waters, near the centre of the continent.
I was assured by the fishermen that the salmon do not decrease in numbers or in size, yet in this year, 1873, more than two millions of pounds were put up in tin cans on the Lower Columbia alone, besides fifteen or twenty thousand barrels of salted salmon.
From Astoria to Portland is a distance of one hundred and ten miles, and as the current is strong, the steamer requires ten or twelve hours to make the trip. As you approach the mouth of the Willamette you meet more arable land, and the shores of this river are generally lower, and often alluvial, like the Missouri and Mississippi bottoms; and here you find cattle, sheep, orchards, and fields; and one who is familiar with the agricultural parts of California notices here signs of a somewhat severer climate, in more substantial houses; and the evidence of more protracted rains, in green and luxuriant grasses at a season when the pastures of California have already begun to turn brown.
Portland is a surprisingly well-built city, with so many large shops, so many elegant dwellings, and other signs of prosperity, as will make you credit the assertion of its inhabitants, that it contains more wealth in proportion to its population than any other town in the United States. It lies on the right bank of the Willamette, and is the centre of a large commerce. Its inhabitants seemed to me to have a singular fancy for plate-glass fronts in their shops and hotels, and even in the private houses, which led me at first to suppose that there must be a glass factory near at hand. It is all, I believe, imported.
From Portland, which you can see in a day, and whose most notable sight is a fine view of Mount Hood, obtainable from the hills back of the city, the sight-seer makes his excursions conveniently in various directions; and as the American traveler is always in a hurry, it is perhaps well to show what time is needed:
