Robert Sterling Yard was an American writer, journalist, and wilderness activist. Born in Haverstraw, New York, Yard graduated from Princeton University and spent the first twenty years of his career in the editing and publishing business. In 1915, he was recruited by his friend Stephen Mather to help publicize the need for an independent national park agency. Their numerous publications were part of a movement that resulted in legislative support for a National Park Service (NPS) in 1916. Yard worked to promote the national parks as well as educate Americans about their use. Creating high standards based on aesthetic ideals for park selection, he also opposed commercialism and industrialization of what he called America's masterpieces. In 1935, he became one of the eight founding members of The Wilderness Society and acted as its first president from 1937 until his death eight years later. Yard is now considered an important figure in the modern wilderness movement. In the preface to this book, published in 1919, he writes, In offering the American public a carefully studied outline of its national park system, I have two principal...

Dr. Walsh's Old-Time Makers of Medicine chronicles the history and development of modern medicine from ancient times up to the discovery of America. Throughout this historical guide, Dr. Walsh shows numerous examples of practices thought to be entirely modern that were clearly anticipated hundreds or thousands of years ago. Ancient healers sought to use the body's natural healing ability, rather than rely exclusively on external cures. Physicians even in ancient times relied on what is now recognized as the placebo effect. Dr. Walsh also addresses training and certification in medicine. Medieval universities anticipate our modern medical textbooks with consolidated records of all research and independent investigations, to provide uniform training for students. Likewise, the reader will find that the ancients reacted to unsuccessful treatment in similar degrees to what might now be called medical malpractice suits. The book is organized chronologically, beginning with the fall of the Roman Empire and growth of the early Christian Church. From there, Dr. Walsh details the development of medical knowledge and practice in Arabia, to Me...

John Wesley Powell was a pioneer American explorer, ethnologist, and geologist in the 19th Century. In 1869 he set out to explore the Colorado and the Grand Canyon. He gathered nine men, four boats and food for ten months and set out from Green River, Wyoming, on May 24. Passing through dangerous rapids, the group passed down the Green River to its confluence with the Colorado River (then also known as the Grand River upriver from the junction), near present-day Moab, Utah. The expedition's route traveled through the Utah canyons of the Colorado River, which Powell described in his published diary as having …wonderful features—carved walls, royal arches, glens, alcove gulches, mounds and monuments. From which of these features shall we select a name? We decide to call it Glen Canyon. (Ironically, now almost completely submerged by Lake Powell, behind the Glen Canyon Dam.) One man (Goodman) quit after the first month and another three (Dunn and the Howland brothers) left at Separation Rapid in the third, only two days before the group reached the mouth of the Virgin River on August 30 after traversing almost 1,500 km. The three who l...

Cyrus W. Field had a dream: to link the Old World of Britain and Europe to that of the New World of North America by a telegraph cable stretching across the great Atlantic Ocean. It took him thirteen years, a lot of money, and many men and ships and cable to make it happen. He wanted to bring the world together and make it a smaller place; to forge alliances and achieve peace. This is his story. (Introduction by Alex C. Telander)...

In the book's preface, the author writes: Let anyone stop to consider how he individually would be affected if all electrical service were suddenly to cease, and he cannot fail to appreciate the claims of electricity to attentive study. In these days when we take for granted all kinds of technology - communications, entertainment, medical, military, industrial and domestic - it is interesting to learn what progress had been made in the fields of electricity and technology by the beginning of the 20th century. Including the dawn of hydro-electric power, the x-ray, the phonograph, the telephone and the wireless telegraph, this book explains the pioneering work of the men who made our modern world possible, and sets us wondering what the next century may bring - providing that we do not manage to destroy our planet in the meantime. The Gutenberg text of the 1915 edition (as recorded) does not have the benefit of the book's many diagrams. Also available, however, is an http://www.archive.org/stream/storyofelectrici00munriala#page/n5/mode/2up online book scan of the 1912 edition which includes the illustrations and coincides largely with...

Charles Darwin’s Origin of Species (publ. 1859) is a pivotal work in scientific literature and arguably the pivotal work in evolutionary biology. The book’s full title is On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life. It introduced the theory that populations evolve over the course of generations through a process of natural selection. It was controversial because it contradicted religious beliefs which underlay the then current theories of biology. Darwin’s book was the culmination of evidence he had accumulated on the voyage of the Beagle in the 1830s and added to through continuing investigations and experiments since his return.
