SURVEY OF THE INTERTROPICAL 
isis. The opening, off which we had anchored, was 
May 23. formed between two low, sandy points, and 
trended in to the S.E. ; on the land at the 
back was a long round-backed hill, which, when 
viewed from the northward, had a flat-topped 
appearance. 
2U Having sounded the space between the anchor- 
age and the shore, it was found that we were on 
the outer edge of a bar, within which the water 
deepened to five fathoms, and in the entrance there 
was as much as eleven and twelve fathoms ; we 
therefore weighed the anchor, and, the wind blow- 
ing out, worked up towards the opening, which, 
as the tide was flowing, it did not take long 
to effect. On passing the bar, we had not less 
water than eleven feet (low water soundings), 
after which the depth gradually increased. An 
anchorage was taken up in the evening within 
the entrance, and the next day, after an attempt 
to reach further up, in which we only succeeded 
to the distance of a mile, the examination was 
completed by our boat. 
It was found to run in, gradually narrowing 
and decreasing in depth for eight miles, and to 
terminate in two salt-water creeks. The banks 
on both sides were impenetrably lined with man- 
groves, which effectually defied our attempts to 
land. Several creeks, communicating with the
