166 A VOYAGE TO [South Coast. 
iso2. the time keepers taken in the same place, was 30' 53" ; showing a 
Friday h i9. difference of no more than o' 31" to the east, since quitting the port. 
This quantity in a sea observation is so small and uncertain, that I 
considered the time keepers to have gone correctly from March 4, 
when the last observations in Port Lincoln had been made, up to this 
time ; and that the lunar observations taken in the interval might 
be reduced back to the head of the port by their means, and used to 
fix its longitude without any further correction. 
Besides the bearings above given, there was a rocky islet four 
miles distant in the S. 7S 0 W. ; part of a ledge of low rocks which 
extended towards the north end of Thistle's Island, and may possi- 
bly be connected with the rock set from thence. This ledge is 
marked dangerous, in the particular chart. 
Having satisfactorily ascertained the going of the time keepers, 
we tacked and stretched back for the coast on the east side of the 
gulph ; but did not get sight of it before dark. At six on the folio w- 
Sahirday 2o. ing morning, 
Corny Point, dist. 5 or 6 leagues, bore - N. 63^° E. 
A cliffy head, distant 10 miles, - - S. 85 E. 
Furthest extreme, a cliffy point, - S. 2 1 E. 
Wedge Island, eastern bluff, - - S. 49 W. 
Thistle's Island, highest part, - - West. 
An amplitude taken when the ship's head was south-by-east, gave 
variation i° 25' east, and azimuths at south-south-east, l° 10': the 
mean, reduced to the meridian, is 2° 13' east, or a few minutes more 
than had been found on the west side of the gulph, and half a degree 
less than off Point Pearce. 
The tide appeared to set us along the shore to the southward, 
although, from what was observed at Thistle's Island, it shouid have 
been the time of flood. With its assistance, and the wind having 
become less unfavourable, we were enabled to make a course for 
the furthest land. This proved to be a cape, composed of three 
cliffy points, near the northern part of which lay a cluster of black
