INVESTIGATIONS OF THE ALBATROSS. 243 
1883, when Capt. Anderson, of the schooner Matthew Turner, passed near 
it and reported a new Bogoslof, with flame, smoke, and steam issuing 
from the crater and numerous fissures in its sides. The revenue cutter 
Corwin examined it in 1884, when it was still active, and a subsequent 
visit in 1885 developed no material change. Sail Rock was reported to 
be 86 feet in height. 
The Albatross passed within three quarters of a mile of the island on 
the afternoon of August 2, 1890, but did notland. It was an unusually 
clear day, Makushin and the high lands of Umnak being distinctly 
visible. Sail Rock had fallen, its original position being marked by the 
débris. New Bogoslof was enveloped in smoke and steam so dense 
that its outlines could not be accurately determined, but its altitude 
was not far from 400 feet. There were no outlying dangers visible, and 
a couple of soundings taken 2 miles from the old cone on different bear- 
ings gave 649 and 578 fathoms, the latter being on the reef marked on 
old charts as extending from Bogoslof to theenorth end of Umnak. It 
is needless to say that this reef does not exist. Myriads of guillemots 
were seen on the island and for 15 miles or more around it, and a part 
of the beach was occupied by a rookery of very large sea lions. Old 
Bogoslof is rapidly crumbling away, and will, like Sail Rock, eventually 
disappear. 
Bering Sea.—A westerly course was continued during the night, and 
at six the following morning the trawl was lowered in 1,033 fathoms, 
latitude 55° 53/ N., longitude 170° 50’ W., making a successful haul. 
The bottom was composed almost wholly of diatomaceous ooze, the 
absence of foraminifera being a marked feature in the waters of Bering 
Sea. The course was then changed to the northward, and soundings 
made at 50-mile intervals, which gave1,745, 1,818, 1,625, and 69 fathoms, 
the latter in latitude 56° 50’ N., longitude 172° 30/ W., and near the 
100-fathom line. Seals were frequently seen after wereached soundings, 
and, the fog lifting for a short time, two sealing schooners were sighted, 
with their boats out in the successful prosecution of their enterprise. 
The line of soundings was extended to latitude 58° 43’ N., longitude 
174° 43’ W., in 144 fathoms, giving the trend of the 100-fathom line 
‘about NW. 4 N., magnetic. A southerly gale sprang, up during the 
eveningsof the 4th, and work was carried on the next day under many 
difficulties and unusual wear and tear of machinery. The rough 
weather told on our supply of fuel also, and finally induced us to turn 
‘to the southward during the afternoon of the 5th. Standing on all 
night under low speed and short sail, a sounding was made next morn- 
ing in 1,887 fathoms, latitude 56° 50’ N., and longitude 175° 15’ W. 
Another one was taken during the afternoon in 1,998 fathoms, green 
ooze, in latitude 56° 02’ N., longitude 175° 35’ W. A bottom temper- 
ature and water specimen were taken in sounding, and subsequently 
serial temperatures and water specimens were taken to 1,000 fathoms, 
the temperatures ranging from 48° F, at the surface to 34,9° F. at the
