to reconcile the bearings, I found it necessary to allow 12° of east variation.

Towards Double Mount and Shoal-water Bay, the country consisted of gently-rising hills and extensive plains, well covered with wood and apparently fertile. The stream at the head of Broad Sound could not be traced from hence more than three or four miles above the tent; but it may possibly run up much further to the south-eastward, though too small to be distinguished in the wood, or to be navigable for boats. To the south and westward there was a ridge of high land, which appeared to be a prolongation of the same whence the upper branches of Port Bowen and Shoal-water Bay take their rise, and by which the low land and small arms on the west side of Broad Sound are bounded. A similar ridge ran behind Port Curtis and Keppel Bay, and it is not improbable that the two are connected, and of the same substance; for at Port Curtis the basis stone of the country was a granite, and this small hill was the same. It has been more than once observed, that granite is amongst the substances which exert an influence upon the magnetic needle; and it is to the attraction of the ridge of mountains to the south and westward, that I attribute the great variation found in the bearings at this station.

We returned to the tent at sunset; and there passed a disagreeable night amongst musketoes, sand flies, and ants. At four in the morning the ebb had made, and we embarked in the boat; but the depth of water was so little that we could not proceed, and were obliged to re-land and wait for the following tide; not without apprehension of being left till the next springs came on. At two in the afternoon the flood came up rapidly, and in half an hour it was high water; we set off immediately, and after some trouble from the shoals, reached the brig at five o'clock. Mr. Murray got under way at three the next morning to beat down to Upper Head, the wind being from the northward; but the Lady Nelson getting
