Within this canyon the Snake River goes over the noted Shoshoné Falls, a series of cataracts. The first one is the Twin Falls descending one hundred and eighty feet, then the river goes down the Bridal Veil of eighty feet descent, and finally it pours in grandeur over the great Shoshoné Falls, nearly a thousand feet wide, and descending two hundred and ten feet, a most magnificent cataract. After the confluence with the Columbia, the latter river leaves the region of sands and lava for the rocks and mountains, and here are the Dalles. These are mainly flagstones that make troughs and fissures, and compress the channel. At first the river, a mile wide, goes over a wall twenty feet high and stretching completely across, and the enormous current is compressed not far below into a narrow pass only a hundred and thirty feet wide and nearly three miles long, encompassed by high perpendicular cliffs of such regular formation that they seem as if constructed of masonry. The Dalles make crooked, trough-like channels through which the waters wildly rush. The amazing way in which the agile fish are able to ascend these rapids and cataract through all the turmoil, seeking the quiet river reaches above, caused the Indians to call the place the Salmon Falls. Here is the town of the Dalles, the supplying market for the Idaho mining district, an active manufacturing place with five thousand people. There are various islands in these rapids, most of them having been used for Indian burial-places and some having numerous graves. Below, the Columbia presents very fine scenery in passing the defiles of the Cascade Mountains, and to the southward is the noble form of Mount Hood, rising over eleven thousand feet, displaying glaciers and having snow-covered peaks all about. At the Cascade Locks the Columbia descends another rapid, where huge rocks buffet the turbulent waters, the whirling foaming torrent wildly rushing among them. Here the descent is twenty-five feet, and the Government has improved the navigation by a spacious ship canal a mile long, built at a cost of $4,000,000. Enormous cliffs, some of grand and imposing form, environ the river in passing through these Cascade Mountains, some rising twenty-five hundred feet. We are told these mountains were first named from the numerous cascades which pour in from tributary streams coming over the cliffs and through the crevices of this tremendous chasm. Often a dozen of these fairy waterfalls can be seen in a single river reach, some dissolving into spray before half-way down, others stealing through crooked crannies, and many being tiny threads of glistening foam apparently frozen to the mountain side. Here is Undine's Veil pouring over a broader ledge, and the Oneonta, Horse Tail, La Tourelle and Bridal Veil cataracts, with the far-famed Multnomah Fall, the most beautiful of all, eight hundred feet high, descending with graceful gentleness over the massive cliffs a long and
