We entered the magnificent harbor of Petropaulovsk by way of a narrow passage, and found ourselves in a landlocked bay, twenty-five miles long and ten miles wide. Its shores were well wooded, and we could see several fine streams as they made their way swiftly down the mountainsides to the waters of the bay. At the northern extremity of the harbor rose the active volcano of Avatcha, sixteen thousand feet high from the water's edge. About its summit lay heavy masses of snow, and above it hovered a thick blanket of smoke. Kamchatka lies in the line of volcanic activity which stretches from Tierra del Fuego in South America northward through South and North America, the Aleutian Islands, Kamchatka, the Kurile Islands, Japan, and so southward; and, therefore, it is not surprising that there should be many semi-active volcanoes on the peninsula as well as many hot springs. The natives consider both of these the habitations of evil spirits, and will not go near them if it can be helped. Once a party of Russians forced the natives to show them the way to one of the hot springs, and when the superstitious people saw the foreigners looking over the edge of the spring, tasting of the water and cooking eggs in it, they were filled with wonder, and thought the Russians had power over the demons. In port we found the British gunboat _Archer_ and a small Russian gunboat. [Illustration: Main Street of Petropaulovsk, Kamchatka.] The town of Petropaulovsk consists of about three hundred Russians and half-caste Kamchadales, presided over by a Russian magistrate, assisted by a secretary, a physician, and twenty Cossacks. With the exception of an imposing cathedral, the houses were all built of logs and one story in height, but they were neat and substantial, and were provided throughout with double windows, which are required by the severity of the winter. At that season of the year the country was covered with a luxurious growth of vegetation. Of trees, so called, there are only the larch and birch, but the whole country is covered with a dense growth of underbrush, ten feet high, which it is impossible to penetrate. Consequently, very little traveling is done in summer, except on the rivers in small boats. Most of this undergrowth dies down at the approach of winter, and the snow which then covers everything makes traveling comparatively easy in any direction.
