All of our continents are being gradually worn down by the action of rains, rills, rivulets, and rivers, and being deposited along the sea margins, just as the Mississippi is gradually stretching out into the Gulf, by the deposition of the muds of the delta.
I'm afraid I'm too late as it is." "Come along, your Grace come along, you," said the inspector briskly. The four of them hurried out of the office and down the steps of the police-station. In the roadway stood a long grey racing-car, caked with muds grey mud, brown mud, red mud from end to end. It looked as if it had brought samples of the soil of France from many districts.
Remains of thousands of species of animals and plants, as perfectly recognizable as those of existing forms of life which you meet with in museums, or as the shells which you pick up upon the seabeach, have been embedded in the ancient sands, or muds, or limestones, just as they are being embedded now, in sandy, or clayey, or calcareous subaqueous deposits.
Even the barren, arid, and windswept eastern slopes glowed bright with the volcanic muds locally called laterites, and the foliated beds of saibros and macapes, decomposed tufas oxidised red and yellow.
Wherever a seaward cliff exhibited a section for our observation, we ought to find these same strata all exposed in regular order the sandstone at the bottom, the clay above it, the broad belt of chalk halfway up, and the Tertiary muds and rubbles at the top. But in the county as we actually find it, we get a very different state of things.
When subsidence was most rapid and long continued the sea encroached far and wide upon the lowlands and covered the coal swamps with sands and muds and limy oozes. When subsidence slackened or ceased the land gained on the sea. Bays were barred, and lagoons as they gradually filled with mud became marshes.
Yet dust deposits are scant and few in great deserts such as the Sahara. The finer waste is blown beyond its limits and laid in adjacent oceans, where it adds to the muds and oozes of their floors, and on bordering steppes and forest lands, where it is bound fast by vegetation and slowly accumulates in deposits of unstratified loose yellow earth.

From this section infer that during early Silurian times the area was sea, and thick sea muds were laid upon it. These were later altered to hard slates by pressure and upfolded into mountains. During the later Silurian and the Devonian the area was land and suffered vast denudation. In the Carboniferous period it was lowered beneath the sea and received a cover of limestone.
She took the estrangement so much to heart that she eased her feelings by abusing Pin in thought; Pin was a pig-headed little ignoramus, as timid as ever of setting one foot before the other. And the rest of them would be just the same old stick-in-the muds, unchanged by a hair, or, if they HAD changed, then changed for the worse.
