A thin film of marl, which before it was dried and condensed by pressure must have represented a much thicker layer of soft mud, intervened between the beds of solid gypsum. On this mud the animals had trodden, and made impressions which had penetrated to the gypseous mass below, then evidently unconsolidated.
Some beds of grit, mingled with ordinary red marl, resemble sands ejected from a crater; and in the stratified conglomerates occurring near Tiverton are many angular fragments of trap porphyry, some of them one or two tons in weight, intermingled with pebbles of other rocks.
In a fourth field two layers of lime, one above the other, could be distinctly traced, and beneath them a layer of cinders and burnt marl at a depth of from 10 to 12 inches below the surface. A piece of waste, swampy land was enclosed, drained, ploughed, harrowed and thickly covered in the year 1822 with burnt marl and cinders.
Marl and clay and green sand and salt and gypsum and shale, all have their genesis, all came down to us in some way or in some degree, from the aboriginal crystalline rocks; but what transformations and transmutations they have undergone! They have passed through Nature's laboratory and taken on new forms and characteristics.
He showed us, that by means of this pole, the extent of the stratum of eggs could be determined as accurately as the miner determines the limits of a bed of marl, of bog iron-ore, or of coal. On thrusting the rod perpendicularly into the ground, the sudden want of resistance shows that the cavity or layer of loose earth containing the eggs, has been reached.
M. de Carosi describes very systematically the generation of silex, calcedony, onyx, and quartz, in calcareous earth, marl, gypsum, sand-stone, and also what he terms terre glaise, ou de l'Argile. It is in this last that we find a perfect analogy with what is so frequent in this country of Scotland.
In the ages succeeding the deposition of the red marl Europe seems to have been broken up into an archipelago of coral reefs and atolls; and the islands of this ancient oolitic ocean were tenanted by numbers of tiny ancestral marsupials, some of which approached in appearance the pouched ant-eaters of Western Australia, while others resembled rather the phalangers and wombats, or turned into excellent imitation carnivores, like our modern friend the Tasmanian devil.
The variegated marl beds which constitute the uppermost group of the formation, present two additional genera of huge saurians, the phytosaurus and mastodonsaurus. It is in the upper beds of the red sandstone that beds of salt first occur. These are sometimes of such thickness, that the mine from which the material has been excavated looks like a lofty church.
For their lust is without a limit, and nought may satiate Their ravening maw; and their hunger if ye check it turneth to hate, And the blood-fever burns in their bosoms, and torment and anguish and woe O'er the wide field ploughed by the sword-blade for the coming years they sow; And ruth is a thing forgotten and all hopes they trample down; And whatso thing is steadfast, whatso of good renown, Whatso is fair and lovely, whatso is ancient sooth In the bloody marl shall they mingle as they laugh for lack of ruth.
By the time the Apaches were out of range the emigrants were well up the slope of the hill which occupied the extreme elbow of the bend in the river. It was a bluff or butte of limestone which innumerable years had converted into marl, and for the most part into earth. A thin turf covered it; here and there were thickets; more rarely trees. Presently some one remarked that the sides were terraced.
