suixiit. No clearly defined crater v/as observed but at the center the 

 crevo^«es were deeper and nore jagged than elscTjhere. Stean is issuing 

 fron quite a number of places all over the top and partly down the sides 

 of the lava area, The lake is also giving forth vapor which is sulphurous, 

 but not to such a degree as to cause irritation, 



"Proceeding in the direction of Fire Island the party cane upon 

 the sea lion herd on the nore northerly rookery on Bogoslof Island. The 

 bulls and cows put off into the v/ater leaving their young on the beach* 

 Some of the pups were so young that they had not yet learned to bark. These 

 did not object to- being petted, but nost of the young sea lions protested 

 with T;hat lung power they have against being touched. During all the tine 

 we stood at the rookery the roar fron the bulls and cows continued unabated 

 and at full blast. The landing party counted 180 pups at this rookery, and 

 as the nore southerly rookery is the larger, the total sea lion population 

 probably runs between 1,000 and 2,000, 



"A number of sea gull eggs were seen upon a plateau away fron the 

 rookeries, and a peculiar fly is quite nuncrous there, 



"It was interesting to note the first sign of vegetation. This 

 consists of snail patches of noss high upon the ncre westerly of the two 

 shej'p peaks, Vifhen on the island twenty years agoi I saw no sign of vege- 

 tation whatever," 



REPORT OF C OMJL'kKDE R F. A. ZEUSIER, U. S. C. G. C. CHEL/'JM, AUGUST, 1954 . 



"The CI-TELilN anchored at 1605 18 August in a conparatively shallow 

 spot on the western side of the island and plans were made to make a re- 

 connaissance survey of the island. On the afternoon of the 18th signals 

 were erected at the most irrportant points and a base line of 800 yards 

 established on Sea Lion Point. On 19 August a reconnaissance by plane 

 table was begun and soimdings were taken up to 20 fathons and to the 

 Unit of the visibility fron the vessel, as internittent fog prevented 

 distant soundings. On the afternoon of 18 August the vessel v/as shifted 

 to the east anchorage. On 19 August, the reconnaissance by plane table 

 was conpleted and a sories of soundings taken on the eastern side up to 

 the 20 fathom depth, A staff compass reconnaissanco was also nade by 

 Professor Alexander in order to check the high water line with the plane 

 table. No opportunity was had to obtain the pcB ition by astrononical 

 observations, iHthough the sun was seen a nunber o^f tines during the 

 day, the horizon was usually obscured, mnkiaig it inpossible to obtain 

 an accurate position, Tlie vessel was gottan underway at 1658, 20 August, 

 as the wind had shiftod to the north northeastward and conditions were be- 

 ccning unfavorable for further surveying, 



"The soundings were taken by the personnel in a motor boat, 

 positions were obta.ined every five soundings by bearings and distances 

 from the bridge by calibrated range finder from tho CHEIAH nnd chocked 

 by calibrated stadinetor in the boat, and the s-^'^ed of the motor boat 

 was determined by the contour of the botton using the standard inotruc- 

 ti.ms as published by the Coast Sixrvey,
