A beautiful clear, still day, favored the circumnavigation of North island, and the careful examination of its coast line. A thick forest of spruce of small growth covers its entire area, down to its rocky shores, which are generally low, though rising to bold perpendicular bluffs from 50 to 200 feet in height at North Point and around Cloak Bay, the highest elevation on the island not exceeding 400 feet above the sea. There are four small bays on its north-eastern side, from one to two miles in depth, open to easterly winds, with fine sandy beaches at their heads where the remains of former habitations were visible. Cloak Bay, a much larger indentation on the south-western shore, is exposed to westerly storms. The safest anchorage these waters afford is found in a little cove on the south shore of the island between Cloak Bay and the village of Henslung. Parry Passage, which separates North Island from Graham is about a mile and a half in width, though the ship channel--very rapid except at flood tide--is narrowed by reefs, and Lucy Island, to less than two thousand feet. Camping at the deserted village of Yakh, near Kioosta, we found large beds of strawberry vines of most luxuriant growth, and carvings of male figures complete. THE WEST COAST. Rounding Cape Knox for nineteen days, thirteen of which were stormy, we fought our way along about 275 miles of shoreline, traversing to their head every inlet, harbor, sound, port and bay, fourteen in all, from three to ten miles in depth, nearly all hitherto unknown, except to a few of the oldest Indians. A rocky, ragged uninviting shore, from which project far out to sea many rocky points with outlying reefs, white with breakers, except during the calmest weather; precipitous mountains from one to four thousand feet in height, clothed with forests of spruce and cedar down to the sea; beautiful land-locked harbors, with short stretches of fine sandy beach at their heads; long winding inlets, down whose mountain walled sides roaring cataracts are plunging; numerous small streams in which salmon and salmon trout were seen by the hundreds; scores of islands, islets and cozy coves, where seal and wild geese abound, describes the general physical features of the west coast of Graham Island. A SUBMERGED FOREST. Tledoo is the name of a summer rendezvous of the sea-otter hunters of Massett, situated about fifteen miles south of Cape Knox. We had landed at Klik-a-doo, a short distance above, the only place visible where the sea appeared not to be breaking, and in examining the coast on foot several miles southward, discovered the tall pole which marks the site of the three cabins of Tledoo. At first view, the sea seemed to be breaking along the entire front, but a more careful examination disclosed a narrow entrance between the rocks through which we were able to enter a perfectly sheltered little canoe harbor with a fine sandy beach at the landing place.
