The coast lies nearly north, and except Sandy Cape, appears to be mostly of free stone, which I have not found to produce any effect upon the needle; and what is remarkable, on comparing my observations with those of captain Cook, it appeared that little or no change had taken place in the variation, during thirty-two years; for wherever our observations were taken with the ships heads in the same direction, there the same variation was obtained to a few minutes.

Within Break-sea Spit, an amplitude gave the variation when corrected, 7° 25' east; and one taken at the anchorage near Sandy Cape, but uncorrected, the direction of the ship's head being unknown, 7° 57' east. There is little doubt that on bringing the land to the eastward of the ship, the variation was diminished at least half a degree: the stone of Sandy Cape is granitic.

SUNDAY 1 AUGUST 1802

In the morning of August 1, the wind was from the southward, and we steered across Hervey's Bay, towards a sloping hummock on the west side, where my examination in the Norfolk had terminated. The soundings increased from 7, gradually to 18 fathoms, and afterwards decreased till half past four in the afternoon; when the sloping hummock bore S. 2° E. eight miles, and we had no more than 3½ fathoms near some dry banks and breakers, which extend out three miles from two shallow inlets in the coast. At dusk the anchor was let go in 6½ fathoms, mud and sand; the shallow inlets to the south being distant 6 miles, and the sloping hummock bearing S. 17° E. In captain Cook's chart, the width of Hervey's Bay is fifty-nine miles, which had appeared to me too great when here in the Norfolk; and I now made the distance, from the north-west extremity of Sandy Cape to a low point running out from the hummock, to be forty three miles by the time keepers. Such errors as this are almost unavoidable without the aid of these instruments, when sailing either along a coast which lies nearly on the same parallel, or where no land is in sight to correct the longitude by bearings. From Port Jackson to Sandy Cape, captain Cook's positions had been found to differ from mine, not more than from 10' east to 7' west; which must be considered a great degree of accuracy, considering the expeditious manner in which he sailed along the coast, and that there were no time keepers on board the Endeavour; but from Sandy Cape northward, where the direction of the coast has a good deal of westing in it, greater differences began to show themselves.

[EAST COAST. NEAR BUSTARD BAY.]

There was a little tide running past the ship in the first part of the night from N. N. W., which appeared to be the flood setting into Hervey's Bay. At daybreak [MONDAY 2 AUGUST 1802] we pursued our course along the shore, at the distance of four or five miles, in soundings between 5 and 9 fathoms. The coast was low, but not sandy; and behind it was a range of hills extending north-westward, and like the flat country, was not ill clothed with wood. There was no remarkable projection till we came to the south head of Bustard Bay; and the night being then at hand, we ran in and anchored on a sandy bottom, in 4½ fathoms, nearly in the same spot where the Endeavour had lain thirty-two years before.

The rocky south head of Bustard Bay, from the survey between the preceding and following noons, should lie in 24° 9' south, and the time keepers placed it in 151° 52' east; or 5' south and 10' east of captain Cook's situation; nor did the form of the Bay correspond to his chart.* The variation observed a few miles from the anchorage, was 8° 20' east, with the ship's head N. W. by N., or 6° 52' reduced to the meridian; nearly as had been found in the morning, when it was 6° 56' corrected. This is a full degree less than it was on the east side of Sandy Cape, and captain Cook's observations show a still greater diminution.

[* The latitude 24° 4' was observed on board the Endeavour, at anchor here; by whom is uncertain, but it was not by captain Cook or Mr. Green. In the Astronomical Observations of the voyage, p. 134, Mr. Wales, in deducing the position of Bustard Bay, takes no notice of this observation, and omits the latitude.]

TUESDAY 3 AUGUST 1802

At daylight we proceeded along the coast; but the wind being very light, were no more than abreast of the north head of Bustard Bay at noon; and the ship being drifted by the tide toward some rocks lying off the head, a boat went to sound amongst them for a passage; in the mean time an air sprung up at north; and having got the ship's head to the eastward, we stretched off from the rocks. This north head lies in latitude 24° 0', as laid down by captain Cook, and bears from the south head N. 44° W., twelve miles; it is moderately high, and behind it is a mass of hummocky, barren hills, which extend far to the westward. A reef lies out as far as two miles from the north head; but within the outer rock above water our boat had 14 fathoms, and there was room for a ship to pass.
