It is situated in front of South-West Bay, is about two miles and a half in circumference, and formed of a large and coarse granular quartzose sandstone, large rounded masses of which cover the surface at its northern end, the summit of which was named Sansom's Head.

It is a huge boulder of reddish sandstone, two-thirds the way up a steep hill on the north bank of the Marias River, about five miles from Fort Conrad.

It was clear that there must have been land close by, for between the beds of coal, as you all know, the rock is principally coarse sandstone, which could only have been laid down (as I have explained to you already) in very shallow water.

Soft shales were exposed in the gullies and on the sides of the hills, and were overlaid compact gray sandstones.

The upper stratum is a bed of ironstone conglomerate about twenty feet thick, this rests on sandstone, the upper part of which is highly ferruginous, then passes away into a variegated sandstone imperfectly stratified, changing into a hard siliceous sandstone which is white and breaks with a conchoidal fracture; this rests on a hard cherty sandstone similar to that of the Victoria River.

At five miles came upon a sandy stream-bed fifty yards wide, trending to the north-east, beyond which the country opened out into an extensive plain of white waving grassto the north uninterrupted by a single elevation, while to the east and south, at eight or ten miles distant, rose ranges of granite hills, capped with horizontal sandstones.

At 4.40 encamped at a fine spring on the bank of a deep pool, under a cliff of metamorphic sandstone nearly 300 feet high; a cane, much resembling a Spanish red, growing in considerable quantities near the water.

The rock which formed the hills on this day's journey is a hard red-brown sandstone, the lower part thin-bedded, beneath which trap or basalt has been forced between the strata, and was exposed in the deep valleys excavated by the creeks.

Having ascertained that the party could be moved across the range to the basalt plains with advantage, commenced our return to the camp by a westerly route across the plain, which rose gently for ten miles, and was well grassed, but thinly wooded; the soil was stony, with fragments of altered sandstone and basalt.

A compact sandstone range, resting on a granite base (which was named the Lockier Range, after Mr. Lockier Burgess, one of the principal promoters of the expedition), here diverts the course of the river to the left, which, by sundown, we found was running nearly south.

The Pinacothek is a magnificent building of yellow sandstone, five hundred and thirty feet long, containing thirteen hundred pictures, selected with great care from the whole private collection of the king, which amounts to nine thousand.

"From what knowledge I have been able to obtain in that department, I am inclined to arrange the secondary class thus: "Breccia: compact, or shell limestone; gypsum, secondary sandstone.

Above all this, there is something like two thousand feet of a lighter colored sandstone.

The only rocks noticed in the parts traversed by the boats were, as I have before said, of red porous sandstone.

Coarse-grained, ferruginous sandstone, containing fragments of quartz, from above the pipe-clay.

Five years after this the exterior of the aisle walls was recased with the same friable sandstone.

The geological character of the island is a red-coloured, coarse-granular, siliceous sandstone, disposed in horizontal strata, and intersected by veins of crystallised quartz.

The upper stratum is a bed of ironstone conglomerate about twenty feet thick, this rests on sandstone, the upper part of which is highly ferruginous, then passes away into a variegated sandstone imperfectly stratified, changing into a hard siliceous sandstone which is white and breaks with a conchoidal fracture; this rests on a hard cherty sandstone similar to that of the Victoria River.

Above all this, there is something like two thousand feet of a lighter colored sandstone.

The cañon through which he was flying was a groove cut in solid sandstone, less than two hundred feet wide, with precipitous walls of fifteen hundred feet, from the summit of which the rock sloped away into buttes and peaks a thousand feet higher.

The hills have decreased in height, the upper strata thick-bedded coarse sandstone with sandstone shale beneath; hard white sandstone exists in some of the lower ridges.

The shores and hills were thickly scattered over with large masses of a dark red-coloured sandstone covered with a crust of quartz; the latter substance was not however found in a crystallized state.

In this comprehensive glance we may also notice the shallow wind-worn caves in stratified sandstones along the margins of the plains; and the cave-like recesses in the Sierra slates and granites, where bears and other mountaineers find shelter during the fall of sudden storms.

They are what is called saccharine (that is, sugary) sandstone.

He pronounces it "a superficial highly ferrugineous sandstone, with concretionary veins and aggregations."
