182 A VOYAGE TO [South Coast. 
l» compared with those of March 24th, showed the time keepers to have 
Fnday'2. erred 2' to" -of longitude to the west, in the nine days we had been 
absent; and they had not, consequently, lost quite so much upon a 
medium as the Port-Lincoln rates supposed. This small error, 
which principally affected the Gulph of St. Vincent, has been cor- 
rected in the longitudes there specified and in the chart, by an equal 
proportion. 
The kanguroos were found to be less numerous than at the 
first anchoring place, and they had become shy; so that very 
few were killed. Those few being brought off, with a boat load of 
Saturdays, wood, we got under way at daylight next morning, to prosecute the 
examination of the coast beyond Cape Jervis ; but the time keepers 
had stopped, from having been neglected to be wound up on the 
preceding day. We therefore came to an anchor again ; and as 
some time would be required to fix new rates, the ship was moored 
so soon as the flood tide made. I landed immediately, to commence 
the necessary observations, and a party was established on shore, 
abreast of the ship, to cut more wood for the holds. Lieutenant 
Fowler was sent in the launch to the eastward, with a shooting 
party and such of the scientific gentlemen as chose to accompany 
him ; and there being skins wanted for the service of the rigging, 
he was directed to kill some seals. 
Sunday 4. On the 4th, I was accompanied by the naturalist in a boat ex- 
pedition to the head of the large eastern cove of Nepean Bay ; in- 
tending if possible to ascend a sandy eminence behind it, from which 
alone there was any hope of obtaining a view into the interior of the 
island, all the other hills being thickly covered with wood. On ap- 
proaching the south-west corner of the cove, a small opening was 
found leading into a considerable piece of water ; and by one of its 
branches we reached within little more than a mile of the desired 
sandy eminence. After I had observed the latitude 35 0 50' 2" 
from an artificial horizon, we got through the wood without much 
difficulty ; and at one o'clock reached the top of the eminence,
