which we had anchored was found to be of small size ; it is probable 

 that we had dropped the anchor on the shoalest place. Vessels have 

 nothing to fear in this respect. 



At 9 a. m. of the 8th, we made the Mangsee Islands ahead of 

 us, and likewise Balabac to the north, and Balambangan to the 

 south. Several sand-banks and extensive reefs were also seen be- 

 tween them. On seeing the ground on which we had to operate, 

 of which the published charts give no idea whatever, I determined to 

 proceed, and take a central position with the ship under the Mangsee 

 Islands ; but in order not to lose time, I hoisted out and dropped two 

 boats, under Lieutenant Perry, to survey the first sand-bank we came 

 to, which lies a few miles to the eastward of these islands, with orders 

 to effect this duty and join me at the anchorage, or find a shelter under 

 the lee of the islands 



At half-past 2 p. m. we anchored near the reef, in thirty-six 

 fathoms water. I thought myself fortunate in getting bottom, as 

 the reefs on closing with them seemed to indicate but little appear- 

 ance of it. 



The rest of the day was spent in preparing the boats for our ope- 

 rations. I now felt the want of the tender. Although in the absence 

 of this vessel, great exposure was necessary to effect this survey, I 

 found both officers and men cheerful and willing. The parties were 

 organized, — the first to proceed to the north, towards Balabac Island, 

 to survey the intermediate shoals and reefs, under Lieutenant Em- 

 mons and Mr. Totten ; the second to the south, tinder Lieutenants 

 Perry and Budd; and Mr. Hammersly for the survey of the shoals of 

 Balambangan and Banguey, and their reefs. The examination of 

 the Mangsee Islands, and the reefs adjacent, with the astronomical 

 and magnetic observations, &c, devolved on myself and those who 

 remained on board the ship. 



The weather was watched with anxiety, and turned out disagree- 

 able, heavy showers and strong winds prevailing; notwithstanding, 

 the boats were despatched, after being as well protected against it as 

 possible. We flattered ourselves that these extensive reefs would 

 produce a fine harvest of shells ; but, although every exertion was 

 made in the search, we did not add as many to our collections as 

 we anticipated. Some land-shells, however, were found that we 

 little expected to meet with, for many of the trees were covered 

 with them, and on cutting them down, large quantities were easily 

 obtained. Mr. Peale shot several birds, among which was a Nico-
