What mark or sign was there upon him at that time of the future that was before him? Can we see him as a fish in the old Devonian seas or lakes? Was he a big fish or a little fish? The primitive fishes were mostly of the shark kind. Is there any connection between that fact and the human sharks of to-day?
As to this there is no dispute; nor, in fact, about the climate from the Cambrian to the Permian. In the Silurian we have "much to suggest uniformity of climate" in fact, we have just the same evidence for it and in the Devonian, when land-plants abound and afford better evidence, we find the same climatic equality of living things in the most different latitudes.
Here lie the level strata, without any bending or folding, or sign of convulsion and upheavals, horizontal as the surface of the sea or lake in which their sediments were originally laid down; and here are these deep, wide valleys cut down through these many sheets of stratified rock; and here are these long, high, broad-backed mountains, made up of the rock that the forces of air and water have left, and with no forces of erosion at work that would appreciably alter a line of the landscape in ten thousand years; and yet we know, if we know anything about the physical history of the earth, that erosion has done this work, carved out these mountains and valleys, from the Devonian strata, as literally as the sculptor carves his statue from the block of marble.
There was a girl among the passengers, a tall, blonde, handsome, strapping Irishwoman, with a wild, accommodating eye, whom Alick had dubbed Tommy, with that transcendental appropriateness that defies analysis. One day the Devonian was lying for warmth in the upper stoke-hole, which stands open on the deck, when Irish Tommy came past, very neatly attired, as was her custom.
I shall not attempt any account of the differences between the animals of the Devonian period and those of the Silurian period, because they consist of structural details difficult to present in a popular form and uninteresting to all but the professional naturalist.
John's in Newfoundland running southwesterly about to the point where the Wisconsin joins the Mississippi, but jutting down to form an extensive peninsula comprising part of the States of Indiana and Illinois, and you include between them all of the United States which existed at the close of the Devonian period.
Her hair and eyes such big bright eyes! were dark; but her complexion was scarcely brunette, and the colour in her cheeks was rich and peach-like, after the true Devonian type. She was dimpled whenever she smiled, and she smiled often; her full lips giving a peculiar ripe look to her laughing mouth that suited admirably with her light and delicate style of beauty.
They quite plainly exist to supply fine blood-vessels for breathing at the gill-clefts, and are never used, for the embryo does not breathe, except through the mother. They are a most instructive reminder of the Devonian fish which quitted its element and became the ancestor of all the birds and mammals of a later age.
The words were scarcely spoken before a shadow was cast across the floor and Mrs. Barraclough appeared at the window carrying a basket of roses. "Conybeare," she said, addressing the old Devonian gardener who was trimming the borders a few yards away. "Conybeare, I am going down to Mrs. Brassbound later in the evening. I want you to cut me a nice bunch of grapes and some vegetables nice ones."
To shorten our story, let me at once say that during the periods that the Ordovician, the Silurian and the Devonian were forming, the Grand Canyon region was either above water so that it received none of these sediments, or, if any were deposited, they were almost entirely removed by the weathering processes before described, ere the region again sank into the ocean to receive the deposits of the Carboniferous epoch.
