By Command of the Lords Commissioners of the Admiralty. Also a Narrative Of Captain Owen Stanley's Visits to the Islands in the Arafura Sea. It is very hilly, and the rock is, where we passed, a rotten slate which the rains and the torrents cut away rapidly, carrying the alluvium down to the plains and Lake of Scutari. The Autobiography of a Journalist, Volume II The same was true of the sands, though the last was rarely of as great depth as the mud, or alluvium. The Crater The land joining Mt. d'Ely to the main is mere alluvium. The Travels of Marco Polo — Volume 2 This stands towering out in lonely sublimity, like the everlasting granite of the Alps or the Himalaya, as compared with the changing alluvium of the Nile or the Ganges. Choice Specimens of American Literature, and Literary Reader Being Selections from the Chief American Writers The lofty mountains, their summits marked with a few patches of snow, stood well separated from each other, the valleys being filled up with an immense thickness of stratified alluvium.

Manual of Gardening (Second Edition) But wind and wave and alluvium working together choke these communications, and directly the mouth seawards of a lagoon is closed it is converted into a stagnating marsh that exhales malaria. In Troubadour-Land A Ramble in Provence and Languedoc That the actual capacity of a channel through alluvium depends upon its service during floods has been often shown, but this capacity does not include anomalous, but recurrent, floods. Life on the Mississippi, Part 12. In this matter theory must bow to "rule of thumb:" the caprices of alluvium are various and curious enough to baffle every attempt at scientific induction.

Prose Idylls, New and Old Lampa, the chief town in the Huancahuanca Canyon, lies on a great natural terrace of gravel and alluvium more than a thousand feet above the river. Inca Land Explorations in the Highlands of Peru To the south of this lay the prehistoric sea; the ground is horizontal, and although subjected to culture shows sufficient evidence that it was at one time sea-bed, covered with more recent alluvium. In Troubadour-Land A Ramble in Provence and Languedoc Down in sheltered lake hollows, on beds of rich alluvium, it varies so far from the common form as frequently to be taken for a distinct species. The Mountains of California By this theory he dispensed with the necessity of filling up pre-existing cavities with stratified alluvium, in the manner proposed by M. de Mortillet. The Antiquity of Man The volcanic revolutions have succeeded each other after long intervals, and at very different periods: of this we see the vestiges in the transition mountains, in the secondary strata, and in those of alluvium. Personal Narrative of Travels to the Equinoctial Regions of America, During the Year 1799-1804 — Volume 1 They are found in a sandy alluvium which is very boggy when wet. Successful Exploration Through the Interior of Australia At every overflow eighteen thousand cubic yards of alluvium was deposited over this district, all of which is now carried into the Mediterranean and thrown down in the construction of new bars; utterly wasted. In Troubadour-Land A Ramble in Provence and Languedoc At an elevation of about 9000 feet above sea-level they seem to have arrived at middle age,—that is, their basins seem to be about half filled with alluvium. The Mountains of California The geological formations of the second period consist of stratified masses of sand and gravel, called the "ancient alluvium" by MM. The Antiquity of Man What Dr. Gillan calls somewhat vaguely, mountains of hard ferruginous clay, are nothing but an alluvium which we find at the foot of every volcano.

Spinifex and Sand He distinguishes the boulder clay, under the name of "the old alluvial cover," from that more modern alluvium, in which the whales of Airthrie, described in Chapter 3, were found. The Antiquity of Man They cut through the alluvium of their flood plains, leaving it on either bank as successive terraces, and intrench themselves in the underlying rock. The Elements of Geology The soft shores of alluvium were constantly caving and falling into the river, bringing down tons of earth and tall forest-trees. Four Months in a Sneak-Box In Australia it has been worked successfully not only in alluvium, but in vein-stones in the native rock, generally consisting of Silurian shales and slates. The Student's Elements of Geology Through the plain are two unmistakable evidences of river-action which at some remote period had washed down from the higher ground the fertile deposit which has formed the alluvium of the valley. Cyprus, as I Saw It in 1879 All this alluvium was evidently of fluviatile origin, for, in the interstices between the pebbles, the Ancylus fluviatilis and other freshwater shells were abundant. The Antiquity of Man Like the recent alluvium of the Great Valley of California, these deposits imply low-lying lands when they were laid, and therefore at that time the mountains rose from near sea level. The Elements of Geology Here, also, a new appearance was presented in some extensive and level banks of alluvium or detritus of the neighbouring metamorphic rocks; but I neglected to observe whether it was stratified or not. Geological Observations on South America Auvergne, alluvium in. —, chain of extinct volcanoes in. —, granite veins in.

Manners and Monuments of Prehistoric Peoples That ere long, now that curiosity has been so much excited on this subject, some human remains will be detected in the older alluvium of European valleys, I confidently expect. The Antiquity of Man Buildings on firm rock suffered least, while those on deep alluvium were severely shaken by the undulations, like water waves, into which the loose material was thrown. The Elements of Geology The valleys are worn by the streams, and, in turn, are built up, leveled, and enriched by the sand and alluvium deposited annually by the floods.

The Mason-Bees Gold mines of Australia and Chili. — veins of Russia. — of California, of age of alluvium. The Student's Elements of Geology Each wave of time contributes its alluvium, each race deposits its layer on the monument, each individual brings his stone. Notre-Dame De Paris Having offered these general remarks on the alluvium of the Thames, I may now say something of the implements hitherto discovered in it. The Antiquity of Man For several centuries also Chinese settlers have been attracted to the south-western district by the gold which they found in the river gravel and alluvium. The Pagan Tribes of Borneo Luckily the fertile alluvium of these valleys, lying parallel with the sea, offered no "indications" to attract the gold seekers. On the Frontier No. 3 represents an older alluvium, composed of sand and gravel, formed before the valley had been excavated to its present depth. The Student's Elements of Geology This skirts the northern shore for a long distance; the soil consisting of alluvium and rich vegetable mould, and exhibiting the most exuberant fertility.

The Pagan Tribes of Borneo The church clothes it with soft alluvium, adorns it with velvet verdure, enriches it with fruits and grains, glorifies it with the beauty of blooms. Gala-days The whole of them were at first confounded with the superficial alluviums of Europe; and it was long before their real extent and thickness, and the various ages to which they belong, were fully recognised. The Student's Elements of Geology Here a thick bed of alluvium will accumulate, ready to be washed away in the course of centuries, as the stream in the middle meanders from side to side. The formation of vegetable mould through the action of worms, with observations on their habits We also find that the older alluvium contains the remains of Mastodon everywhere, and in some places, as at Evansville, those of the Megalonyx.

The Exiles The reader will not therefore be surprised to learn that flint implements of the same antique type as those of the valley of the Somme have been detected in British alluvium. The Antiquity of Man Here and there, dwarf spruce, rooting and grovelling in the shallow alluvium, marked the proximity of the timber line. The God of His Fathers: Tales of the Klondyke Over this, in a higher bed of alluvium, were several polished hatchets of the more modern type called "celts," and above all loam or cave-mud, in which were Gallo-Roman antiquities.* The Antiquity of Man These subterranean vaults are usually filled in part with mud, pebbles, and breccia, in which bones occur belonging to the same assemblage of animals as those characterising the Post-pliocene alluvia above described. The Student's Elements of Geology Again, the tides and currents of the estuary, by changing their direction, might sweep away a considerable mass of alluvium from the bottom, laying bare a canoe that may have foundered many centuries before. The Antiquity of Man The latter seems never to have been seen before in the old alluvium of France.* The Antiquity of Man In the alluvium of all parts of the valley, both at high and low levels, rolled bones are sometimes met with in the gravel. The Antiquity of Man In that elevated alluvium the remains of a Tertiary mastodon and other quadrupeds of like antiquity are embedded. The Antiquity of Man Besides, the last operations of water have a tendency to disturb and confound together all pre-existing alluviums. The Student's Elements of Geology In the "Principles of Geology," when treating of the fossil remains found in alluvium and the mud of caverns, I gave an account in 1832 of the investigations made by MM. The Antiquity of Man If, therefore, the relative ages of the Picardy and Natchez alluvium were to be decided on conchological data alone, the fluvio-marine beds of Abbeville might rank as a shade older than the loess of Natchez.
