FISH COMMISSION STEAMER ALBATROSS DURING THE SUMMER OF 1890. BY LIEUT. COMMANDER Z. L. TANNER, U. S. NAVY. [Accompanied by three charts, forming Plates cvm-cx.] INTRODUCTION. Bering Sea was designated as the working ground for the steamer Albatross dur- ing the summer of 1S90, the object of the cruise being to develop its offshore fishing grounds. The exploration of the cod banks of Bristol Bay occupied most of the time, and this report is chiefly limited to adiscnssion of that region. We also made a par- tial reconuoissauce of the coast lines as an indispensable preliminary to the fishery investigations. In prosecuting the work the region was thoroughly sounded, the currents, wind, and weather observed, and other information obtained of such direct value to the fisherman and mariner that it was deemed advisable to present the prin- cipal results in advance of the regular report. All the bearings given are magnetic, and the depths are expressed in fathoms. Longitudes depend upon Dall's astronom- ical station, Iliuliuk Harbor (point opposite the wharf), being in longitude 166° 31' 44.2" W. Bristol Bay may be said to include all that part of Bering Sea lying east of a line drawn from the Northwest Cape of Unimak Island to the Kuskokwim River. The Island of Unimak and the Alaska Peninsula bound it on the south and east, and sep- arate it from the Pacific Ocean. The Naknek River is at the head of deep-water navigation, while the bay itself terminates in the Kvichak River, a few miles to the northward. The region about the Nushagak River, Kulukak Bay, and the Kuskokwim forms its northwest boundary. The shore lines are usually low, and without distinctive features, but high moun- tain ranges and volcanic cones extend along the central parts of Unimak and the Alaska Peninsula. These rugged snow-covered mountains and lofty peaks would serve as unmistakable landmarks were they not obscured by the almost constant fogs which prevail in that region during the summer months. In fact, they were so seldom visible during the season of 1890 that the officers of the Albatross made no pretense 279 280 BULLETIN OP THE UNITED STATES FISH COMMISSION of using them as landmarks. The shore line and objects near the sea level were ofteD seen beneath the fog when the higher lands were obscured, and, therefore, most of the available landmarks were found on or near the beach. THE COAST FROM TJNIMAK PASS TO POET MOLLEB. The Northwest Cape of Unimak is low with detached rocks, around which strong tidal currents sweep. The land falls away to the eastward in a gentle curve, forming an open bay about 4 miles in depth between the cape and Cave Point, which lies NNE. £ E., 16 miles from the former. It is a vertical rocky cliff about 150 feet in height, aud takes its name from a cave on its face, inhabited by sea birds which in summer time hover about it in thousands, making it conspicuous in clear weather by their num- bers and in fogs by their constant cries. The snow-clad peak of Progrumnoi Volcano, rising to an altitude of 5,523 feet above the sea, forms a striking background to the low monotonous coast. Passing Cape La-pin, a low bluff point 8 miles from Cave Point, the coast falls away slightly for
