Inside Illinois - Mineral Resources
by AnonymousAlthough Illinois has been nicknamed the “Prairie State,” many parts of it are hilly and scenic. The idea of large areas of the state being nothing more than broad, flat prairies has come about because the major highways have been built to take advantage of the comparatively low, gently rolling landscape rather than the rougher more scenic areas.Ph..
A Monograph of the Trilobites of North America
by Jacob GreenSome geologists imagine that the order of creation is registered in the rocks which compose the external crust of the earth, and that they can there clearly read a progressive development of organic life; in other words, that a succession of more perfect animals may be traced in ascending from the lower strata to the upper or more recent formations..
Our Nuclear Future
by Edward TellerThis book has been written for the layman who has no knowledge about atoms, bombs and radioactivity. He knows that the world is made of atoms, that bombs might destroy it and that radioactivity could make it a place much less agreeable to live in. We should like to give some advice about the use of the book: Each chapter can be read by itself...
The Moon - A Popular Treatise

The Ivory King
by Charles Frederick HolderThe elephant is the true king of beasts, the largest and most powerful of existing land animals, and to young and old a never ceasing source of wonder and interest. In former geological ages, it roamed the continental areas of every zone; was found in nearly every section of North America, from the shores of the Arctic Ocean to the Gulf of Mexico, ..
The Life of the Grasshopper
by Jean-Henri FabreFame is built up mainly of legend; in the animal world, as in the world of men, the story takes precedence of history. Insects in particular, whether they attract our attention in this way or in that, have their fair share in a folk-lore which pays but little regard to truth.For instance, who does not know the Cicada, at least by name? Where, in th..
Butterflies and Moths, Shown to the Children
by Theodore WoodIn this little book I want to tell you something about the common butterflies and moths which you may find in almost all parts of the country. But, first of all, I think that perhaps I had better say something about what we generally call their “life-history.”Of course you know that butterflies and moths are not butterflies and moths to begin with...
