Along the western base of the range a telling series of sedimentary rocks containing the early history of the Sierra are now being studied.

To the timid traveler, fresh from the sedimentary levels of the lowlands, these highways, however picturesque and grand, seem terribly forbiddingcold, dead, gloomy gashes in the bones of the mountains, and of all Nature's ways the ones to be most cautiously avoided.

The phonolite stones of the Rhine, and the Tripoli stone, contain species identical with what are now contributing to form a sedimentary deposit (and perhaps, at some future period, a bed of rock) extending in one continuous stratum for 400 measured miles.

Succession implies time; the lower members of an undisturbed series of sedimentary rocks are certainly older than the upper; and when the notion of age was once introduced as the equivalent of succession, it was no wonder that correspondence in succession came to be looked upon as a correspondence in age, or "contemporaneity."

Thus: Animals and plants began their existence together, not long after the commencement of the deposition of the sedimentary rocks; and then succeeded one another, in such a manner, that totally distinct faunae and florae occupied the whole surface of the earth, one after the other, and during distinct epochs of time.

It is mathematically certain that, in any given vertical linear section of an undisturbed series of sedimentary deposits, the bed which lies lowest is the oldest.

Assuming this rate of denudation as certain, and also the estimate of the known sedimentary strata as 177,000 feet in depth, we are to conclude that the formation took 56,000,000 years.

Now suppose that after these sedimentary beds are laid down by water, the volcano breaks out againwhat would happen?

It burrows out through the softer ash-beds, and between the sedimentary beds, spreading itself along horizontally.

But if not, sooner or later, it bores up through the new sedimentary rocks, faulting them by earthquake shocks till it gets free vent, and begins its layers of alternate ash and lava once more.

We should have a right to do so, because that would be true of most sedimentary rocks.

Adj. remaining, left; left behind left over; residual, residuary; over, odd; unconsumed, sedimentary; surviving; net; exceeding, over and above; outlying, outstanding; cast off &c 782; superfluous &c (redundant) 641. 40a.

Analysis shows that the water of the Colorado River carries a larger percentage of sedimentary deposit than any other river in the world, not excepting the Nile.

These are zones or layers of a sedimentary rock, to the bedding of which they are conformable, impregnated with ore derived from a foreign source, and formed long subsequent to the deposition of the containing formation.

The Cloudmaker appears to be diorite; Mt. Buckley sedimentary.

As a step towards 'getting these things clearer' in his mind two spare pages of the diary are filled with neat tables, showing the main classes into which rocks are divided, and their natural subdivisionsthe sedimentary, according to mode of deposition, chemical, organic, or aqueous; the metamorphic, according to the kind of rock altered by heat; the igneous, according to their chemical composition.

They seem to mark the line where the volcanic forces which raised the high islands in the Bay of Fonseca had their first conflict with the sedimentary and primitive rocks of the interior.

The exhaustive experiments of Dr. Angus Smith in Scotland, and the interesting reports of French examiners, have made the scientific world familiar, not only qualitatively but quantitatively, with the chemical nature of some rains, as well as with their solid sedimentary contents.

Once Haught called my attention to a flat stone with a plain trail made by a turtle in ages past when that sandstone was wet, sedimentary deposit.

So tremendous a chasm would be one of the world's greatest wonders even if, like ordinary cañons cut in sedimentary rocks, it were empty and its walls were simple.

The sedimentary rock of sandstone, shales, and marl, not only showed veins of ignitible lignite, but it was pierced by the trap which had been shot up from earth's flaming recesses.

The Universalists had a bran-new one, and there was still another frequented by the sedimentary part of the populationMethodists.
