AIN RIVER, opposite Kwa-kans Island and a group of islets. We ascended this stream about ten miles, five on foot and thence by canoe through two small lakes to its source in Soo-u-uns Lake. This fine body of water is about eight miles long and three miles wide, surrounded by a thick forest of spruce, red and yellow cedar. Mountains rise gradually from its western and north-western sides to the height of from eight to fifteen hundred feet. The river, from fifty to seventy-five feet in width, is navigable for canoes, about a mile from its mouth, and also between the small lakes mentioned, by means of several portages--log-jambs, shoals and rapids. There are seven Indian lodges at its mouth, this stream being a great resort for salmon. It is about twelve miles from the mouth of the Ain River to the end of the north-western arm of the sound, which having no name on the chart, I have called NEWTON INLET. It is about six miles in length, and two miles wide, with an island at its entrance, known as Mut-oos, and several islets. _En route_ we found two small streams, to the largest of which my attention was first attracted by the noise of rapids at its mouth. This is called by the Indians, Ta-tzun-in. Ascending it by wading, with considerable difficulty, its bed was seen to be chiefly limestone rock. There are two rivers flowing into Newton Inlet from fifty to seventy-five feet in width, navigable for canoes at high tide about half a mile, when shoal rapids are reached. Steep mountains from 1,500 to 3,000 feet in height, separate this inlet from the waters of the Pacific. Five or six miles to the south-eastward begins TI-IN-OWE INLET, which extends south-westerly between four and five miles, having an average breadth of two miles. Two streams flow in at its head, up the largest of which we ascended about one-third of a mile at high tide, when a log jamb was found. There are three inlets between Tin-in-owe and the entrance to Tsoo-skatli Inlet, about ten miles to the south-eastward, and many islands and islets, the largest of which is called Wat-hoo-us Island. Into the first of these inlets flows the Awun River, rising in Awun Lake, about one hundred feet wide at its month, and which we were able to ascend with our canoe about one mile, when rapids were reached. Advancing several miles beyond on foot, the river was found choked with frequent log jambs. There is an Indian cabin and small garden plat cultivated for potatoes, at its mouth. Proceeding eastward, we next enter a small bay into which descends, over a precipitous ledge of rocks, a river, the outlet of a small lake hidden from view by a narrow belt of timber; then follows a deeper indentation about a mile in length and half a mile in width to near its head, where an island narrows it for a short distance to less than a hundred feet. Having seen here the largest number of jelly fish found on the islands, I have named it Zoos Inlet.*
