this very strange, as it' vjas a bonutiful clear night with a gentle 

 northerly wind, and I immediately concluded from these weather condi- 

 tions, and its direction, that it had soitiething to do with Bogoslof , 

 as thimder storms arc unheard of in the Boring Sea, especially in 

 September, At daylight, an hour later, ray suspicion was confirmed, 

 IVhen Bogoslof was first sighted, both Castle and Fire Island were 

 visible; Perry Poalc was in state of eruption. At first it resembled 

 in appearance a waterspout, which afterwards spread and enveloped the 

 whole island. On approaching the island it was foiuid to be in violent 

 state of eiuption, throwing up immense clouds of vapor, smoke and ashes, 

 A thick, dark cloud hung over the island, and at the same tine a tongue 

 of flame could be seen shooting up from the crater. Intermittent forked 

 lightning split the clouds extending to the crater, followed by sharp 

 ■peals of thunder, 



"We were then four miles southwest of the island, and the wind 

 shifting from northeast blew dix^ectly to"7oxds the ship. It was nccessa.ry 

 to steam to the northward to avoid the ashes, some of v/hich fell on the 

 ship's deck, and which I gathered and marked "Specimen "K". 



"The eruption though constrtnt was intermittent in intensity, 

 and presented an ever changing aspect. Vapor rose to a height of sev- 

 eral thousand feet, spreading at the top and assuming a nushroon appear- 

 ance resembling a huge white caulif lower. Then at tines in the center of 

 this white mass would appear n black streak of ashes, and mud, most of 

 which fell on the island but some on the sea, pattering like immense 

 drops of rain, 



"Officers and men stood en deck fascinated v/ith the magnificont 

 spectacle, which was still further enhanced by the rays of the rising 

 sun just peeping over Mount Makushin, 



"After getting to windward of the island, we approached to within 

 a little over a mile. All sea lions and gulls had disappeared, I deemed 

 it. imprudent to send a boat close to shore to obtain soundings, as I was 

 afraid the wind which was light might suddenly shift, 



"After remaining in the vie inity several hours and tpkiing some 

 valuable photographs, wo proceeded to Chernofski, 



"On the morning of the 21st, when returning to Unalaska, Bogoslof 

 was cbscrvod to be still steaming." 



Report of Lieutenant Commander K, W. Perry, U.S.R.C. :&a\M'3ING 1911, 



"On a cruise from Unalaska to Attou we kept off our course in 

 order to visit these islands. Wc found that one island had entirely 

 disappeared and the other greatly changed from its former appearance. 

 The remains of Perry Peak emitted some smoke. Finding no anchorage the 

 MANNING la.y to and a party of us landed. We walked by shore half wny 

 around the island then walked across to our starting point. Ttie s\irface 

 tfas crusted and thickly perforated by fumeroles. Putting a finger into 

 one of these, I found it very hot below the surface. This made us a bit 

 uneasy and we hastened to the beach rjid went aboard ship, 



"The hordes of birds forrerly there had practically disappeared 

 and the only sea lions we saw wore in a small herd swimming along shore."
