ROE'S RIVER, at the eastern termination of York Sound (Narrative 1) runs between precipitous banks of sandstone, in nearly horizontal strata, which rise to the height of three hundred feet.
CAREENING BAY, between York Sound and Prince Regent's River (Narrative volume 1. See the plate volume 1). Crystalline epidote, and whitish quartz, apparently from a vein. Purplish-brown epidote, with small nests or concretions of green epidote and quartz; forming a sort of amygdaloid. Conglomerate, containing angular fragments of yellowish-grey quartz-rock, in a base of compact epidote. A nearly uniform greenish compound of epidote intimately mixed with quartz, also occurs at this place. Flat lamellar chalcedony. Very fine-grained reddish-grey quartzose sandstone, with traces of a slaty structure, resembling that of York Sound, and Cambridge Gulf, was found in the north-east end of this bay; and fine-grained greenstone, on the summit of the adjacent hills.
Several of these specimens are almost identical with those of Port Warrender; from which place Careening Bay is distant about sixty miles.
BAT ISLAND (Narrative volume 1) western entrance of Careening Bay. Quartz from thin veins, with particles of an adhering rock, probably chlorite-slate. Quartz, containing disseminated hematitic iron-ore and copper pyrites. Quartz crystals, with chalcedony, from nodules in amygdaloid. Quartz with specular iron ore. Greenstone, with chalcedony and copper pyrites. A decomposed stone, probably consisting of wacke. The specimens of trap-rocks from this place are from a cavern.
GREVILLE ISLAND, near the entrance of Prince Regent's River. Reddish, coarsely granular, siliceous sandstone; in horizontal strata, intersected by veins of crystallized quartz.*
(*Footnote. Narrative volume 2.)
HALF-WAY BAY, within Prince Regent's River on the west of the entrance, near Greville Island. Hornblende rock ? nearly agreeing with that of Pobassoo's Island, on the north-west of the Gulf of Carpentaria (see above). Calcedony, apparently from nodules in amygdaloid. Greenish quartz, approaching to heliotrope. Red, somewhat slaty jasper, mixed with quartz and chalcedony, and containing specular iron ore.
The specimens from this place much resemble some of those from Sotto i Sassi, in the Val di Fassa in the Tyrol, which I have seen in the collection of Mr. Herschel; and which consist of reddish jasper with chalcedony, and a greenish flinty stone, like heliotrope, the whole belonging to the trap-formation.
POINT CUNNINGHAM, east of south from Cape Leveque, and about one hundred and fifty miles south-west of Prince Regent's River. Very compact and fine-grained reddish granular quartz, with a glistening lustre, and flat conchoidal fracture. This stone, though so compact in the recent fracture, has distinct traces of stratification on the decomposed surface, which is of a dull reddish hue. Bright red ferruginous granular quartz (Eisen-kiesel ?) with a glistening lustre, and a somewhat porous texture. A specimen of the soil of the hills at Cygnet Bay, consists of very fine reddish-yellow quartzose sand. A large rounded pebble, consisting of ferruginous granular quartz, of a dark purplish-brown colour, and considerable density, was found here; near a fireplace of the natives, by whom it is used for making their hatchets; with a fragment of a calcareous incrustation, like that of the west coast hereafter mentioned.
The next specimens in Captain King's collection--a space of more than three hundred miles on this coast not having been examined by him--are from MALUS ISLAND, in Dampier's Archipelago (see Narrative volume 1) they consist of fine-grained greenstone, and what appears to be a basaltic rock, of amygdaloidal structure.
