6U VOLCANIC EEGIONS. 



The whaler Sheffield, Captain Green, April 26th, 1859, in lat. 29° 56' N., 

 long. 60° 10' W., experienced three severe shocks of earthquake, between 

 4^ 25™ and 6'' 10™ a.m. The oflScer on duty reported that the sea for some 

 time previously had presented the appearance of a tide-rip ; the noise 

 might be compared to that of a heavily loaded cart or waggon, drawn 

 rapidly over a plank road. 



On December 2nd, 1882, at 6.30 p.m., a heavy shock was felt on board 

 the barque Aneroid, of Swansea, then homeward bound with a cargo of 

 copper-ore. The position given was lat. 24° 29' N., long. 64° 38' W., 

 nearly midway between Porto Eico and Bermuda, and according to the 

 Challenger soundings hereabout the depth would be nearly 3,000 fathoms. 



On March 13th, 1891, between 7 and 8 p.m., Capt. Petersen, of the 

 barque Eleanora, experienced a submarine disturbance in the volcanic 

 region West of St. Paul Eocks, in lat. 3° 47' N., long. 42° 3' W. The 

 vessel was heading N.W., going about 3 knots, when a noise was heard 

 like a heavy surf, and the sea began to bubble and boil, the broken water 

 reaching as high as the poop deck. It lasted about an hour, but no 

 distinct shock was felt. It then ceased for an hour, when a similar dis- 

 turbance again ensued. 



On November 20th, 1890, in lat. 8° 45' N., long. 40° 28' W., Capt. 

 Crosbie, of the barque P. J". Carleton, reported that the sea became like a 

 boiling pot, tumbling about in a seething mass, and greatly confused. A 

 grating sensation was felt, as though going over a reef. 



On April 1st, 1887, Capt. Lassan, of the Norwegian barque Petty, in 

 lat. 17° 38' N., long. 46° 34' W., felt three distinct shocks, accompanied 

 by an eruption of gas bubbles, covering the surface. 



On January 24th, 1887, Capt. Erskine, of the barque St. Lucie, in lat. 

 27° 39' N., long. 43° 54' W., felt three distinct shocks of about 5 seconds 

 each, shaking his vessel severely. 



On August 23rd, 1891, at 10.30 a.m., in lat. 36° 44' N., long. 59° 47' W., 

 Capt. Hughson, of the steamer Bobert Harrowing, reports that the sea 

 became strangely and unusually disturbed, the commotion increasing 

 until the decks were filled with water. At 1 p.m. the sea suddenly 

 became calm. 



On November 6th, 1886, when in 13 fathoms, southward of Charleston, 

 the captain of the barque Amelia Camp felt an earthquake shock. And 

 on the same day, in lat. 32° 50' N., long. 78° 23' W., Capt. Cates, of the 

 brig Arcot, experienced a very heavy shock, lasting about 12 seconds, 

 shaking the vessel as if dragging over rocky bottom. There was nothing 

 unusual noticeable in the motion of the sea. 



On September 23rd, 1887, between 7 and 8.45 a.m., several shocks 

 were experienced by three vessels off the S.E. end of Cuba, in an area 

 about 250 miles in diameter, shaking them as though they had touched 

 the ground. Capt. Armstrong, of the steamer Alps, felt the first shock in 

 lat. 19° 44' N., long. 74° 24' W. ; it lasted about 45 seconds. The sea 

 was smooth, but appeared to rise in a solid body without the least break. 

 The other two vessels were off the northern side of the S.E. end of Cuba.
