the time keepers taken in the same place, was 30′ 53″; showing a difference of no more than 0′ 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. 78° W.; part of a ledge of low rocks which extended towards the north end of Thistle's Island, and may possibly 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 following morning, An amplitude taken when the ship's head was south-by-east, gave variation 1° 25′ east, and azimuths at south-south-east, 1° 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 should 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
