It is twice as old as the Bnmiosaurus. five times as old as the Eohippus, a hiuiflred times as old as the mammoth or mastodon or the earliest known remains of man to all who are likewise interested in the past history of the earth, in the extinct races of animals and plants which ha\e formerly inhabited it, in the evolution of those which now exist, the Coal Era has a broader interest. For the antifpie world of this remote period, many millions of years ago, was widely difl'erent in its appearance, in the outlines of its con- tinents, in the character of its plants and animals, from the present day. There were no broad-leaved trees nor flowering plants, no birds nor mam- mals nor any of the higher kinds of insects.
