hitherto examined in the Aleutian Islands, Small quantities of rock- 

 froth consisting of unfused particles in a semi-fusod mass were seen, 

 but the heat of discharge has evidently never been sufficient to produce 

 film fusion. Specimens of dust collected from one of the vents was 

 compared with volcanic dust which fell in the village of Ounalaska 

 October 20, 1883, and found to be identical in character, 



"Dosconding to the beach on the east side I found it to be much 

 the same formation as on the west side, with perhaps the exception that 

 the line of sand hero approaches nearer the water-line. Tlie pebbles 

 seen on the island are universally of a dark-gray color, with small 

 black spots .and worn surface by attrition. 



"I saw no shells and but little sea-weed. Kelp in considerable 

 quantities,, .hovrever, was observed close inshore, 



"A walk of a third of a mile brought me to old Bogoslov, where 

 the beach abruptly terminates, Tlie nortliGrn end of this rock rises 

 almost porpendlcularly to a distance of some 325 footo Its face is 

 deeply indentod at the base,, forming a cave-like irsccss vjhich gives 

 the rock the appearance of loaning toi/ard .tho norths 



"Probably no¥/hero can there be found a bottor example of the 

 disintegration of stone into soil by tho action of tho atmosphoro. 

 The composition of the islot was originally of slate or shale. It is 

 noT/ breaking dov;n on all sides and crtKibling to dust. The central 

 portion seemed to be composed of a more enduring substance, but a close 

 examination was impossible on account of the loose, crumbling nature 

 of the rock forming the sides and the precipitous ascent. I fired a 

 rifle-shot into a flock of puffin, myi-:i.d^ds of which were perched in the 

 clefts and niches of the rock, and when they roso small pieces of stone 

 were detached and inturn displaced larger pioces of stone until a por- 

 foct avalanche of stone came down the declivity, scoring groat ruts in 

 the hillside and tearing up groat masses of stone, which wero dashod 

 to pieces on the shore below, 



"Spocimons of outer rock were found at the base of the old Bogoslov, 

 on the southern side,' which, being struck with a hammer, crumbled to 

 dust, in somo cases deeply tinted with rod, showing tho prosonco of 

 iron. 



"Eard bowlders of some hard, smooth stone fringe the bases of both 

 tho old and new Bogosloff, but a careful examination of the surrounding 

 T/aters, both in small boats and on board the OORWIN, failed to show any 

 outlying dangers. A spot of sand and pebble formation extends from the 

 southern end of old Bogoslov four-tenths of -a mile in a southeasterly 

 direction, and, like the isthmus connecting the two islands, is probably 

 submerged at times of highest tides or during severe storms. The depth 

 of water around the island is shown iipon tho cliart acconp-anying the roiiort. 



"Puffin in great numbers were seen on old Bogoslov, and it is 

 probable thoy make this isolated spot a breeding place, I also saw 

 numbers of harloauin-ducks, gulls, and kittiwakos. A dead albatross 

 was picked up on the boach, but it is probable it was washed ashore.
