First, we have the Azoic period, devoid of life, as its name signifies, namely, the earliest stratified deposits upon the heated film forming the first solid surface of the earth, in which no trace of living thing has ever been found.
It seems that these antiquities date from the very end of the neolithic, or rather to the succeeding 'chalcolithic', age; whether they are really prehistoric, as regards Babylonian history, must until more evidence from stratified deposits is found remain undecided.
I sailed three or four miles down the east coast of the inlet with the Reid party's cook, who is supposed to be an experienced camper and prospector, and landed at a stratified moraine-bank. It was here that I camped in 1880, a point at that time less than half a mile from the front of the glacier, now one and a half miles.
To the north of Cromer are other fine illustrations of contorted drift reposing on a floor of Chalk horizontally stratified and having a level surface. These phenomena, in themselves sufficiently difficult of explanation, are rendered still more anomalous by the occasional enclosure in the drift of huge fragments of Chalk many yards in diameter. d. Chalk with regular layers of flints. c.
The greatest height to which marine shells have yet been traced in this boulder clay is at Airdie, in Lanarkshire, ten miles east of Glasgow, 524 feet above the level of the sea. At that spot they were found imbedded in stratified clays with till above and below them.
We see another exhibition of the magnitude of the earth's forces in what the geologist calls a "laccolite" a great cave or cistern deep beneath the surface of stratified rock filled with hardened lava.
I found traces of stratified pebbles and sand on the north flank of the Lavanchi moraine however, which I failed to discover in those of Lachoong. The river is fourteen yards broad, and neither deep nor rapid: the village is on the east bank, and is large for Sikkim; it contains fully 100 good wooden houses, raised on posts, and clustered together without order.
If such an eruption has force enough to break through these beds, the hot, melted masses will pour out through the rent, flow over its edges, and fill all the lesser cracks and fissures produced by such a disturbance. What will be the effect upon the stratified rocks?
In that time the stratified rocks have been deposited under water, the land and sea have taken their present configurations; the atmosphere has been purified; plants and animals have spread all over the surface. Man has probably been from twenty to a hundred thousand years or more on the earth, but his civilization is a thing of yesterday." "How long will the earth continue fit for life?"
One example more I wish to give, not only as it is much to the purpose, and properly described, but because it contains the natural history of a coast well known from the circumstance of the Giant's Causeway which it contains; a coast composed of stratified chalk indurated and consolidated to a species of marble or lime-stone, and of great masses of basaltes or columnar whin-stone.
