Excerpt from Open-Air Studies: An Introduction to Geology Out-of-Doors In 1895, in the preface to the first edition of this little book, I sought to excuse its imperfect mode of treatment of a wide and impressive subject. Some slight knowledge of chemistry and physics may happily be presupposed, and the first chapter is chiefly intended as a reminder of what may be learnt in school. The main part of the book, however, is addressed to those wh...

Excerpt from Aids in Practical Geology While the size of the book has not been increased in this edition, alterations have been made in more than one hundred places, whereby, it is hoped, the fairly wide subject-matter has been brought up to date or more adequately set before the reader. The book has always aimed at aiding those who enquire into the materials and history of the earth's crust, for purposes of research or for any special enterp...

Excerpt from Rocks and Their Origins Rocktaluses, and all the varied alluvium carried seaward as the outcash of continental land, well deserve a chapter to themselves. But there is really no end to the subject, which embraces all the accumulative processes of the earth. A few vacation-journeys, judiciously planned out, teach us that text-books are merely signposts to set us on what is believed to be the way. When the path enters the great for...

Excerpt from Outlines of Mineralogy: For Geological Students The subject Mineralogy is of fundamental interest to workers in many sciences. A century ago, the study of the materials that diversify the earths crust was regarded as a natural occupation among men of taste and leisure. The "grand tour" of Europe, which became more and more possible at the close of the Napoleonic wars, opened the eyes of many to the wealth of mineral substances th...

Excerpt from The Changeful Earth: An Introduction to the Record of the Rocks SO much attention is now given to the practical and systematic study of science in schools, that the valuable in¿uence of descriptive scientific literature is apt to be overlooked. An intimate knowledge of the simplest fact in Nature can be obtained only by personal observation or experiment in the Open air or the laboratory, but broad views of scientific thought and...

Excerpt from The Growth of EuropeThis book attempts to show how the surface features of Europe are the result of remarkable and comparatively recent changes, in which the wearing away of the rocks and the deposi tion of continental waste have played a far smaller part than the actual upheaval and depression of the land. These surface-features are intimately related to the movements of man across them, and it is hoped that the 'traveller in fam...
