Natural history is deservedly a popular subject. The manifestations of life in all its varied forms is a theme that has never failed to attract all who are not destitute of intelligence. From the days of the primitive cave-dwellers of Europe, who lived with mammoths and other animals now lost to the world; of the ancient Egyptians, who drew and painted on the walls of their magnificent tombs the creatures inhabiting the delta of the Nile; of the Greeks, looking out on the world with their bright and child-like curiosity, down to our own times, this old, yet ever new, theme has never failed. Never before was there such a profusion of books describing the various forms of life inhabiting the different countries of the globe, or the rivers, lakes, and seas that diversify its scenery. Popular writers have done good service in making the way plain for those who wish to acquaint themselves with the structures, habits, and histories of living animals; while for students a still greater supply of excellent manuals and text-books has been, and still continues to be, forthcoming.
But in our admiration for the present we forget the great past. How seldom do we think of that innumerable host of creatures that once trod this earth! How little in comparison has been done for them! Our natural-history books deal only with those that are alive now. Few popular writers have attempted to depict, as on a canvas, the great earth-drama that has, from age to age, been enacted on the terrestrial stage, of which we behold the latest, but probably not the closing scenes.
When our poet wrote “All the world’s a stage,” he thought only of “men and women,” whom he called “merely players,” but the geologist sees a wider application of these words, as he reviews the drama of past life on the globe, and finds that animals, too, have had “their exits and their entrances;” nay more, “the strange eventful history” of a human life, sketched by the master-hand, might well be chosen to illustrate the birth and growth of the tree of life, the development of which we shall briefly trace from time to time, as we proceed on our survey of the larger and more wonderful animals of life that flourished in bygone times.
We might even make out a “seven ages” of the world, in each of which some peculiar form of life stood out prominently, but such a scheme would be artificial.
There is a wealth of material for reconstructing the past that is simply bewildering; and yet little has been done to bring before the public the strange creatures that have perished.[1]
[1] Figuier’s World before the Deluge is hardly a trustworthy book, and is often not up to date. The restorations also are misleading. Professor Dawson’s Story of the Earth and Man is better; but the illustrations are poor. Nicholson’s Life-History of the Earth is a student’s book. Messrs. Cassells' Our Earth and its Story deals with the whole of geology, and so is too diffusive; its ideal landscapes and restorations leave much to be desired.
To the writer it is a matter of astonishment that the discoveries of Marsh, Cope, Leidy, and others in America, not to mention some important European discoveries, should have attracted so little notice in this country. In the far and wild West a host of strange reptiles and quadrupeds have been unearthed from their rocky sepulchres, often of incredibly huge proportions, and, in many cases, more weird and strange than the imagination could conceive; and yet the public have never heard of these discoveries, by the side of which the now well-known “lost creations” of Cuvier, Buckland, or Conybeare sink into the shade. For once, we beg leave to suggest, the hungry pressman, seeking “copy,” has failed to see a good thing. Descriptions of some of “Marsh’s monsters” and how they were found, might, one would think, have proved attractive to a public ever on the look out for something new.
