On the western side of this harbour there are several inlets and deep bays, but too shoal to be of any service. The eastern shore of the harbour is formed by PERON'S PENINSULA, which separates it from HAMELIN'S HARBOUR. It is sixteen leagues long and five leagues wide. DAMPIER'S BAY, at the north-west end, contains several sandy bays, where boats may almost always land. It is here that the French had their observatory. From the northern point of the peninsula, Pointe des Hauts-Fonds, the reefs extend for three leagues to the North and North-North-West. They were then supposed to extend to the North-East. The French only examined the western shores of Hamelin Harbour. The opposite coast was seen only at a distance, and the shoalness of the water prevented their boats from approaching it. M. De Freycinet says: "Ces terres, basses et steriles, ne contiennent aucune coupure; l'uniformite y est par-tout complete," page 194. Although Hamelin Harbour is not so deep as that of Henry Freycinet, on the opposite side of Peron's Peninsula, it is nevertheless of larger size. The centre is much occupied by banks, which entirely surround FAURE ISLAND; the diameter of which is about two leagues. Although many sandy beaches were seen at a distance upon the eastern shore of Shark's Bay, yet the boats of the French ships could not reach the shore on account of the reefs which front it. Here and there they distinguished red cliffs, and some signs of a scanty and burnt up vegetation. Of the anchorages in Shark's Bay, the most convenient appears to be that in Dampier's Bay, at the north-west end of Peron's Peninsula, as well on account of the excellency of the holding-ground, as the facility of procuring fuel. The Naturaliste remained a long time at this anchorage, and never experienced any ill effect from the winds. The distance from the shore was six miles, and the depth six fathoms, fine sandy bottom. The sea was so clear, that the anchor was easily distinguished. The Naturaliste found only occasion to moor with a kedge, merely to keep the cable clear of the anchor. As the strongest winds were the South and East, the bower anchor was laid in the latter direction. The above seems to be all that is worth taking from M. De Freycinet's account as regards the navigation of Shark's Bay. The coasts of the harbours of Henry Freycinet and Hamelin are much more detailed by him, and there is also much valuable information upon various heads, particularly as to meteorological observations, and the productions of the land and sea, and a curious example of the effect of a mirage; but as these subjects are irrelevant to the matter of this paper, they have been disregarded.
