COMPLETE THE SURVEY OF PORT PHILLIP. As it was now necessary for us to think of preparing for our return to the North coast, the proper season for passing through Torres Strait also approaching, and the increasing importance of Port Phillip, rendering it desirable to complete our survey of its entrance before our departure; we consequently proceeded thither. We found even soundings of 53 fathoms extend twenty miles North by East from Harbinger Reef, but from thence northwards, the depths gradually decreased. Calms and light winds rendered the passage across very tedious. We spent one night at anchor in 31 fathoms near the entrance, about six miles south from Point Flinders, where the tide scarcely ran a knot an hour; the flood-stream set North-East. With these operations closed our work in Bass Strait, for the present. We had completed the western entrance from Port Western on the north shore and Circular Head on the south. The weather had prevented our doing more, and obtaining as many soundings as we could have wished. It had been unusually boisterous and unsettled, much more so than the winter generally is. From all I could learn such a season had not been experienced in the memory of the oldest inhabitants. March 1. Bidding adieu to our hospitable friends, we left Port Phillip, and having spent a night at Port Western, stood out from it next morning, and passed over in 12 and 15 fathoms, the patch of discoloured water discovered by Flinders, two miles south of the remarkable round islet, that lies off the western extreme of Grant Island. Pursuing our course to the eastward, we were detained by contrary winds for some time among the islands at the eastern entrance of the Strait. All these we found to be considerably out in position, showing the necessity of an accurate survey. We were exceedingly delighted when on the 5th we were enabled fairly to turn our back on Bass Strait, that region of storms, which stretched behind us as we receded like a black mass resting on the horizon. A strong south-wester soon carried us far away from it in the direction we had been so long endeavouring to pursue. At noon on the 8th, we were close in with the land in the neighbourhood of Jervis Bay. A long line of cliffs fronts the shore; but the highlands recede as in the neighbourhood of Sydney, leaving a low tract of country between them and the sea. PIGEON HOUSE. To the South-West of this bay, we had an excellent view of that singular landmark, which Captain Cook, with his usual felicity in the choice of names, called the Pigeon House. It was just open of the south end of some tablelands, and resembled a cupola superimposed upon a large dome.
