“The rocks, or foundations of the hills, are composed chiefly of a dark blue, and very hard stone, intermixed with small particles of glimmer or quartz. This seems to be one of the most universal productions of nature, as it constitutes whole mountains in Sweden, in Scotland, at the Canary Islands, the Cape of Good Hope, and at this place. Another brownish brittle stone forms here some considerable rocks; and one which is blacker, and found in detached pieces, incloses bits of coarse quartz. A red, a dull yellow, and a purplish sand-stone, are also found in small pieces; and pretty large lumps of semi-transparent quartz, disposed irregularly in polyedral pyramidal crystals of long shining fibres. Some small pieces of the common sort are met with in the brooks, made round by attrition; but none hard enough to resist a file. Nor were any of the other stones acted on by aqua fortis, or attracted by the magnet. “Nothing that had the least appearance of an ore or metal was seen.” CHAP. VI. PASSAGE FROM KERGUELEN’S TO VAN DIEMEN’S LAND.—ARRIVAL IN ADVENTURE BAY.—INCIDENTS THERE.—INTERVIEWS WITH THE NATIVES.—THEIR PERSONS AND DRESS DESCRIBED.—ACCOUNT OF THEIR BEHAVIOUR.—TABLE OF THE LONGITUDE, LATITUDE, AND VARIATION.—MR. ANDERSON’S OBSERVATIONS ON THE NATURAL PRODUCTIONS OF THE COUNTRY, ON THE INHABITANTS, AND THEIR LANGUAGE. After leaving Kerguelen’s Land, I steered E. by N., intending, in obedience to my instructions, to touch next at New Zealand, to recruit our water, to take in wood, and to make hay for the cattle. Their number, by this time, had been considerably diminished; two young bulls, one of the heifers, two rams, and several of the goats, having of late died, while we were employed in exploring this desolate coast. The 31st, in the morning, being the day after we stood out to sea, we had several observations of the sun and moon. Their results gave the longitude 72° 33ʹ 36ʺ E. The time-keeper, in this situation, gave 72° 38ʹ 15ʺ. These observations were the more useful, as we had not been able to get any for some time before, and they now served to assure us that no material error had crept into the time-keeper. On the 1st of January, being then in the latitude of 48° 41ʹ S. longitude 76° 50ʹ E. the variation was 30° 39ʹ W. and the next day, in the latitude of 48° 22ʹ S., longitude 80° 22ʹ E., it was 30° 47ʹ 18ʺ W. This was the greatest variation we found in this passage; for afterward it began to decrease, but so slowly, that, on the 3d, in the evening, being then in the latitude of 48° 16ʹ S. longitude 85° E. it was 29° 38ʹ W.
