Petchora
a large river in the N. of European Russia, rises on the W. slope of the Urals, flows N. through the E. parts of the governments of Vologda and Archangel, then S. E. for about 150 miles, and finally sweeping toward the N., and expanding into an estuary 30 miles wide and full of islands, falls into the Arctic Ocean, after a course of over 1,000 miles. It is navigable by boats for upward of 700 miles. The country through which the river flows is thinly peopled, and quite uncultivated.
