64 basalt here presenting a columnar formation. We come now to the last, and by far the most singular, portion of the gorge of the Columbia. The river here flows for eight miles through a narrow channel, cut in solid trap-rock, and more or less tortuous. It is, of course, not navigable, and travellers by the river make a portage by rail to Celilo, at the upper end of the gorge. The word dalles comes from the French word dale, a trough or conduit, and was first applied by the French voyageurs, being corrupted into its present form of spelling by Americans.

I am not aware that soundings have ever been taken in this part of the river.

Boats have gone through this passage. In low water the barges of the Hudson's Bay Company used to run the dalles. One or two steamers have been brought through at a low stage of water; but it is a very perilous undertaking,—much more perilous than going over the Cascades at high water.

In the early history of the country it was fixed upon by the Methodists as a mission station; but failing in their efforts to instruct the Indians, or intimidated by their warlike
