In October, 1798, they left Port Jackson: after spending some time among the islands which crowd the straits, they sighted Cape Portland, a name given it in honor of the Duke of Portland, then secretary for the colonies; thence they passed Port Waterhouse, so called after the captain of the _Reliance_. The first important discovery was Port Dalrymple, called after the hydrographer of the admiralty, Alexander Dalrymple.[10] Green Isle, Western Arm, Middle Island, Whirlpool Reach, Swan Point, and Crescent Shore, preserve memorials of the visit in their designations. They reported Port Dalrymple an excellent place for refreshments: black swans, whose quills covered the beach in countless thousands; kangaroos, of the forest kind; flocks of ducks and teal, and mussels and oysters, were found in abundance. Proceeding along the coast, they came to a headland, which they called Circular Head, from its resemblance to a Christmas cake. They now approached the solution of the question which had dictated their voyage. They remarked a long swell from the south-west breaking on the western shore: they hailed it with joy and mutual gratulation, and passed in safety the clustering islets in their course: the extreme north-west they called Cape Grim. Proceeding round the western coast, they observed the mountains noticed by Tasman when he visited the island, which in memory of his vessels they called Mount Heemskirk and Mount Zeehaan. They named Point Hibbs after the master of the _Norfolk_. The discoveries of Flinders here may be said to terminate, until he proceeded up the Derwent. The utility of the strait was highly rated. It secured perpetual renown to Bass, whose name it bears: this was given by Governor Hunter at the recommendation of Flinders, whose candour is always conspicuous in awarding the palm of discovery to those to whom it is due! Not only does the strait curtail a voyage from the Cape by four degrees, but vessels avoid the winds which obstruct navigation round the South Cape and Cape Pillar of Van Diemen's Land, which prolong the passage several days; a point of great importance in the conveyance of passengers. The _Norfolk_ steered into the Derwent by the chart of Hayes. Both Flinders and Bass observe, with indignation, how creeks are magnified into rivers, coves into bays, and a few acres into plains: as Risdon River, Prince of Wales's Bay, and King George's Plains. They corrected his definitions, but left him the honors of discovery. Flinders proceeded to Herdsman's Cove, which he so distinguished for its extensive pasture and plentiful waters. Bass depicts the Derwent as a dull and lifeless stream, respectable only because the Tasmanian rivers are insignificant![11] To a bay they entered on the western side of Tasman's Peninsula, they gave the name of their vessel, which was built at Norfolk Island, of the pine peculiar to that place.
