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 Emmons
and Mr. Totten; the second to the south, under 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,
etc., devolved on myself and those who remained on board the ship.

The weather was watched with anxiety, and turned out disagreeable,
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 Nicobar
pigeon; some interesting plants and corals were also added. On the
island a large quantity of drift-wood was found, which with that
which is growing affords ample supplies of fuel for ships. No fresh
water is to be had, except by digging, the island being but a few
feet above high-water mark.

Although the time was somewhat unfavorable, Lieutenant Emmons and
party executed their orders within the time designated, and met with no
other obstructions than the inclemency of the weather. This was not,
however, the case with Lieutenant Perry, who, near a small beach on
the island of Balambangan, encountered some Sulus, who were disposed
to attack him. The natives, no doubt, were under the impression that
the boats were from some shipwrecked vessel. They were all well armed,
and apparently prepared to take advantage of the party if possible;
but, by the prudence and forbearance of this officer, collision was
avoided, and his party saved from an attack.

[Balambangan.] The island of Balambangan was through the
instrumentality of Mr. Dalrymple, as heretofore stated, obtained
from the Sulus for a settlement and place of deposit, by t
