The soundings were such as to prove the non-existence of all except 

 the Georgia Bank off the east end of Jamaica, which had been recently 

 searched for by several vessels. It was originally discovered by Capt. 

 John S. Holt, of the American brig Georgia, in 18G7, who reported 14 

 fathoms in about latitude 17° 4G' N., longitude 75° 45' W. An exten- 

 sive and careful search was made for this, resulting in the discovery of 

 a bank with a least depth of 17 fathoms a little to the southward of the 

 reported position, in latitude 17° 3G' to 17° 44' X., longitude 75° 40' to 

 75° 45' W. The Navy Department has given it the name of Albatross 

 Pjank. This must not be confounded with the Albatross Shoal off the 

 northwestern shore of Cuba, which was reported by the German gun- 

 l)oat of that name, and not subsequently found. 



One hundred soundings were taken ofl'Cape San Antonio, extending 

 to just beyond the range of the light, with deep water everywhere (up 

 to 1,200 fathoms), and Saucho Pardo Shoal has, in consequence, been 

 expunged from the charts of the Hydrographic Office, Xavj- Depart- 

 ment. 



Six lines of soundings were run across the Caribbean Sea, four between 

 the Leeward Islands and the Main, and diagonal lines on and olf the 

 coast of tlie United States of Colombia. The eastern i)art of the Carib- 

 bean Sea is the deepest, the greatest depth being 2,844 fathoms, in lati- 

 tude 13° 25' X., longitude 00° 25' W. Off the Honduras coast, however, 

 still deeper water was found, there being 3,109 fathoms at 00 miles 

 southwest of the Grand Cayman. 



An interesting discovery was that of a submarine ridge connecting 

 the islands of Santa Cruz and Puerto Rico, the least depth on which 

 was 578 fathoms and the greatest 900, while on either side was found 

 over 2,000 fathoms. 



Aves Islet, 100 miles westward of Guadaloupe, was found to be the 

 summit of a mountain, precipitous on its western slope and extending 

 in a south-southeast direction over 150 miles to the 1,000-fathom curve.
