The village of Market Blandings is one of those sleepy English hamlets that modern progress has failed to touch; except by the addition of a railroad station and a room over the grocer's shop where moving pictures are on view on Tuesdays and Fridays. The church is Norman and the intelligence of the majority of the natives Paleozoic.
In the morning, to my inquiry as to who the travelers were and what they wanted, La Chance said they were old acquaintances going a-fishing, and had stopped to have a little talk. Breakfast was served early, and we were upon the road before the sun. Then began a forty-mile ride through a dense Canadian spruce forest over the drift and boulders of the paleozoic age.
Unmoved witnesses of the innumerable revolutions that have upheaved our planet, the Lingulae are to-day what they were at the remotest times of the paleozoic era. The truth is that adaptation explains the sinuosities of the movement of evolution, but not its general directions, still less the movement itself.
Cockroaches infested the swamps, and one hundred and thirty-three species of this ancient order have been discovered in the Carboniferous of North America. The higher flower-loving insects are still absent; the reign of the flowering plants has not yet begun. The Paleozoic insects were generalized types connecting the present orders.
Towards the close of this Paleozoic era the Appalachian Mountains were slowly upheaved in great convoluted folds, some of them probably reaching three or four miles above the sea-level, though the tooth of time has since gnawed them down to comparatively puny limits.
And should such an hypothesis eventually be proved to be true, in the only way in which it can be demonstrated, viz. by observation and experiment upon the existing forms of life, the conclusion will inevitably present itself, that the Paleozoic, Mesozoic, and Cainozoic faunae and florae, taken together, bear somewhat the same proportion to the whole series of living beings which have occupied this globe, as the existing fauna and flora do to them.
There is a laboratory of invertebrate paleontology of Paleozoic age, with a corps of paleontologists. Mr. C.D. Walcott is in charge. There is a laboratory of fossil botany, with a corps of paleobotanists, Mr. Lester F. Ward being in charge.
It is divided into four long periods, the Silurian, Devonian, Carboniferous, and Permian. The collective depth of these strata is put at 40,000 to 45,000 feet. In any case, the paleozoic age, taken as a whole, was much shorter than the preceding and much longer than the subsequent periods.
In sketching the outlines of the continent as it was at the beginning of the Paleozoic, it must be remembered that wherever the Lower Cambrian formations now are found was certainly then sea bottom, and wherever the Lower Cambrian are wanting, and the next formations rest directly on pre-Cambrian rocks, was probably then land.
Interbedded with the Triassic sandstones are contemporaneous lava beds which were fed from dikes. Volcanic action, which had been remarkably absent in eastern North America during Paleozoic times, was well-marked in connection with the warping now in progress.
