to be sickly; and fearing that
the north-west monsoon might return before his examination was finished,
and keep him in the Gulph beyond the extent of his provisions, he
abandoned the voyage and steered for Mauritius in his way to Europe.

The situation of Fort Concordia is considered to be 10 deg. 91/4' south and
123' 35' 46" east, according to the observations made in the Investigator
(see Ch. IX). I took altitudes with a sextant and artificial horizon on
the 11th, 12th, 13th, and 14th, for the rate of the time keeper, which,
with its error from mean Greenwich time at noon there on the last day of
observation, was found to be as under:

Earnshaw's No. 520, slow 0h 32' 59.91" and losing 36.74" per day.

From the first observation on the 11th p.m., the longitude given with
the rate from Wreck Reef, was 123 deg. 48' 34", or 12' 48" too far east; but
on using a rate equally accelerated from that found at Wreck Reef to this
at Coepang, the time keeper will differ only 0' 40" to the east, which is
the presumable amount of its irregularities between Oct. 6 at noon and
Nov. 11 p.m., or in 36.2 days. The longitudes of my track from Wreck Reef
to Timor have been corrected agreeably to the accelerated rate, with the
further allowance of a part of the supplemental error 0' 40",
proportionate to the time of each observation; but in Torres' Strait, the
situations are fixed from a medium of the longitudes so obtained and of
those of the Investigator with the corrections specified in Ch. VI.,
preceding; the difference between them no where exceeding 11/2' of
longitude.

[FROM TIMOR. TOWARDS MAURITIUS.]

MONDAY 14 NOVEMBER 1803

On the evening of the 14th we sailed from Coepang, and having passed
round the north end of Pulo Samow, steered south-westward with a fair
breeze; but the wind being light, and afterwards veering to S. S. W., our
progress was slow. At sunset on the 16th [WEDNESDAY 16 NOVEMBER 1803],
the island Savu was seen to the N. W. by N., and next morning [THURSDAY
17 NOVEMBER 1803] at six o'clock, the following bearings were taken.

Savu., the highest part, N. 39 deg. E.
Benjoar, a round hill on it, N. 22 E.
A rocky islet, distant 3 leagues, N. 48 W.

At noon, the rocky islet bore N. 63 deg. E., and its position was ascertained
to be 10 deg. 491/2' south and 122 deg. 49' east. A small low island is laid down
by admiral D'Entrecasteaux, about three leagues to the north-west of this
position,
