9.05 stopped alongside of it; latitude 45° 35', longitude 49° 28'. 

 Found this first berg of the season to be of medium size, composed 

 of two parallel walls, the larger of which was some 250 feet in 

 length, some 100 feet in height, and perhaps 60 feet thick at base, 

 tapering to jagged edge on top. The smaller wall was similar to 

 the larger and approximately two-thirds its size in each dimension. 

 The swell pulsating through the open space some 50 feet wide be- 

 tween the walls showed depth of some 10 feet over the base. 



Lieutenant Von Paulsen requested permission to tr}^ one of the 150- 

 pound T.N.T. wrecking mines sent on board for experimenting in 

 destruction of bei-gs. This request was granted, and that officer, with 

 surf boat creAv, lowered a mine alongside base of berg, secured by 

 means of grapnel hooked in ice crevice above water. The mine failed 

 to explode and was hoisted up and brought back to the vessel. Ex- 

 amination showed that one wire of detonator had been broken. At 

 11 stood to windward of berg and anchored in 37 fathoms of water 

 (90 fathoms chain) to observe drift of berg for the day. Berg 

 drifted to southward about one-fourth mile per hour. 



Received ice report from steamship Gorm. (Growler.) 



March 27 : Day begins with light north airs and breezes, hauling 

 to east and increasing to fresh breeze by noon and moderate gale SE. 

 at close. Mostly cloudy to overcast. At 5.35 up anchor and stood to 

 berg, which had drifted to southward distance of some 5 miles in 18 

 hours. Lieutenant Yon Paulsen, with surfboat crew, placed another 

 150-pound depth charge mine on base of berg, and again it failed to 

 explode. Hoisted mine and examined it aboard and decided that 

 detonator designed for smaller mine was not sufficiently in contact 

 with T.X.T. Made adjustments accordingly and lowered another 

 mine alongside base of berg at depth of some 17 fathoms. This was 

 successfully exploded at 8.30. Many tons of ice was brought down 

 from both walls of the berg. The entire berg rocked back and forth, 

 but did not capsize, evidently being partly sustained by proximity to 

 bottom. Broken ice drifted off in form of small growlers and slush. 



At 9.05 stood 165° true to investigate report just received from 

 West Quechee of berg to southward. At 1.40 sighted berg bearing 

 143°, distance 19.5 miles, and stood for it. At 4 stood around berg 

 and photographed it (latitude 44° 31', longitude 49° 05') ; then stood 

 265° true for anchorage on edge of bank. At 4.50 anchored, with 

 100 fathoms chain, in 35 fathoms of water, Avith sand and shell bot- 

 tom; latitude 44° 25', longitude 49° 20'. Tried fishing, without suc- 

 cess ; evidently too early in season. 



Ice reports received this day from steamships West Quechee and 

 Rosalind. Derelict report from steamship Ben NecK-om. 



March 28 : Moderate to fresh SE. to SSW. breezes until 4 p. m., 

 then falling: to fresh and gentle SAV. to WXW. breezes ; heavv swell
