And for literary training, especially, the influence of natural beauty is simply priceless Under the present educational systems, we need grammars and languages far less than a more thorough out-door experience. On this flowery bank, on this ripple-marked shore, are the true literary models.
Sandstone surfaces, ripple-marked, are found throughout the subsequent formations: in those of the new red, at more than one place in England, they further bear impressions of rain-drops which have fallen upon them the rain, of course, of the inconceivably remote age in which the sandstones were formed.
Some of the sandstones are ripple-marked, and towards the upper part of the whole series a thin seam of coal has been observed, measuring, together with some associated carbonaceous shale, about three inches in thickness.
At last she got to the end of the stones, and then, oh joy! there lay before her a beautiful smooth stretch of ripple-marked sand how delightful it was to run along it, so firm and pleasant it felt to her tired little feet. The lighthouse seemed still a good way off farther than she had expected, but at first, in the relief of having got off the stones, she almost felt as if she could fly.
At the base of the Cambrian strata in Sweden, which in the neighbourhood of Lake Wener are perfectly horizontal, lie ripple-marked quartzose sandstones with worm-tracks and annelid borings, like some of those found in the Harlech grits of the Longmynd. Among these are some which have been referred doubtfully to plants. These sandstones have been called in Sweden "fucoid sandstones."
If complex and enigmatical appearances did not present themselves, it would be a serious objection to the metamorphic theory. Mr. Sorby has shown that the peculiar structure belonging to ripple-marked sands, or that which is generated when ripples are formed during the deposition of the materials, is distinctly recognisable in many varieties of mica-schists in Scotland. Lamination of clay-stone.
In Cheshire two beds of salt occur of the extraordinary thickness of 90 or even 100 feet, and extending over an area supposed to be 150 miles in diameter. The adjacent beds present ripple-marked sandstones and footprints of animals at so many levels as to imply that the whole area underwent a slow and gradual depression during the formation of the red sandstone.
Some of the Upper Ludlow sandstones are ripple-marked, thus affording evidence of gradual deposition; and the same may be said of the accompanying fine argillaceous shales, which are of great thickness, and have been provincially named "mud-stones."
