A VOYAGE TO
[South Coast.

1802.
March.

Port Lincoln is certainly a fine harbour; and it is much to be regretted that it possesses no constant run of fresh water, unless it should be in Spalding Cove, which we did not examine. Our pits at the head of the port will however, supply ships at all times; and though discoloured by whitish clay, the water has no pernicious quality, nor is it ill tasted. This and wood, which was easily procured, were all that we found of use to ships; and for the establishment of a colony, which the excellence of the port might seem to invite, the little fertility of the soil offers no inducement. The wood consists principally of the eucalyptus and casuarina.

Of the climate we had no reason to speak but in praise; nor were we incommoded by noxious insects. The range of the thermometer on board the ship was from 66° to 78°, and that of the barometer from 29,94 to 30,20 inches. The weather was generally clouded, the winds light, coming from the eastward in the mornings, and southward after noon. On shore, the average height of the thermometer at noon was 76°.

No corresponding observation of the solar eclipse appears to have been made under any known meridian, and from the nature of circumstances, the error of the moon's place could not be observed at Greenwich; the distances would therefore seem most worthy of confidence, and are adopted; but the longitude deduced from the
