Brigands of the Moon by Ray Cummings Brigands of the Moon

Gregg Haljan was aware that there was a certain danger in having the giant spaceship Planetara stop off at the moon to pick up Grantline’s special cargo of moon ore. For that rare metal — invaluable in keeping Earth’s technology running — was the target of many greedy eyes. But nevertheless he hadn’t figured on the special twist the clever Martian brigands would use. So when he found both the ship and himself suddenly in their hands, he knew that there was only one way in which he could hope to save that cargo and his own secret — that would be by turning space-pirate himself and paying the Brigands of the Moon back in their own interplanetary coin.

In effect Professor Newland declared that the curious astronomical phenomena of the previous November--the new "stars" observed, the two meteors that had fallen with their red and green light-fire--were all evidence of the existence of intelligent life on the planet Mercury. (An excerpt from chapter 1. )

Book cover Wandl the Invader

There were nine major planets in the Solar System and it was within their boundaries that man first set up interplanetary commerce and began trading with the ancient Martian civilization. And then they discovered a tenth planet--a maverick! This tenth world, if it had an orbit, had a strange one, for it was heading inwards from interstellar space, heading close to the Earth-Mars spaceways, upsetting astronautic calculations and raising turmoil on the two inhabited worlds. But even so none suspected then just how much trouble this new world would make...

Book cover Tarrano the Conqueror

In "Tarrano the Conqueror" is presented a tale of the year 2430 A.D.--a time somewhat farther beyond our present-day era than we are beyond Columbus' discovery of America. My desire has been to create for you the impression that you have suddenly been plunged forward into that time--to give you the feeling Columbus might have had could he have read a novel of our present-day life. To this end I have conceived myself a writer of that future time, addressing his contemporary public. You are to imagine...

The People's Common Sense Medical Adviser by Ray Vaughn Pierce The People's Common Sense Medical Adviser

The People's Common Sense Medical Adviser In Plain English, Or, Medicine Simplified. By R.V. Pierce, M.D. INTRODUCTORY WORDS. Health and disease are physical conditions upon which pleasure and pain, success and failure, depend. Every individual gain increases public gain. Upon the health of its people is based the prosperity of a nation; by it every value is increased, every joy enhanced. Life is incomplete without the enjoyment of healthy organs and faculties, for these give rise to the delightful sensations of existence...

The Planet Strappers by Raymond Z. Gallun The Planet Strappers

The Planet Strappers started out as The Bunch, a group of student-astronauts in the back room of a store in Jarviston, Minnesota. They wanted off Earth, and they begged, borrowed and built what they needed to make it. They got what they wanted--a start on the road to the stars--but no one brought up on Earth could have imagined what was waiting for them Out There!

Discourse on the Method of Rightly Conducting One's Reason and of Seeking Truth in the Sciences by René Descartes Discourse on the Method of Rightly Conducting One's Reason and of Seeking Truth in the Sciences

The Discourse on Method is best known as the source of the famous quotation “cogito ergo sum”, “I think, therefore I am.” …. It is a method which gives a solid platform from which all modern natural sciences could evolve. With this work, the idea of skepticism was revived from the ancients such as Sextus Empiricus and modified to account for a truth that Descartes found to be incontrovertible. Descartes started his line of reasoning by doubting everything, so as to assess the world from a fresh perspective, clear of any preconceived notions.

After London, or Wild England by Richard Jefferies After London, or Wild England

First published in 1885, After London, or Wild England is considered to be one of the earliest instances of post-apocalyptic fiction, describing the effects of an unspecified catastrophe that dramatically changes the face of England and its population. Divided into two parts, the first depicts the fall of civilization, as society reverts to its more primitive roots, while the second part is set years after the apocalyptic event and examines the evident changes in both natural scenery and social structure...

Book cover I Was a Teen-Age Secret Weapon

Poor Dolliver Wims is a terribly misunderstood teen age boy from the backwoods. Is he mean or evil? Quite the opposite: He does nothing wrong, hurts no one and wants only to be liked and to help, yet he seems to be blamed for every accident that ever happens to anyone in the University research facility where he 'works' as a porter. Why does disaster seem to swirl around him like a tornado whips around it's eye. He never is hurt in the slightest way while others slash themselves with previously innocent knives, are smashed by falling bookcases that had no cause to fall, and are shot by guns that are safely tucked away...

The South Pole; an account of the Norwegian Antarctic expedition in the Fram, 1910-12 by Roald Amundsen The South Pole; an account of the Norwegian Antarctic expedition in the Fram, 1910-12

In contrast to Scott’s South Pole expedition, Amundsen’s expedition benefited from good equipment, appropriate clothing, and a fundamentally different primary task (Amundsen did no surveying on his route south and is known to have taken only two photographs) Amundsen had a better understanding of dogs and their handling, and he used of skis more effectively. He pioneered an entirely new route to the Pole and they returned. In Amundsen’s own words: “Victory awaits him who has everything in order — luck, people call it...

NATURAL HISTORY OF THE MAMMALIA OF INDIA AND CEYLON.By Robert A. Sterndale, F.R.G.S., F.Z.S., &C., PREFACE. This work is designed to meet an existing want, viz.: a popular manual of Indian Mammalia. At present the only work of the kind is one which treats exclusively of the Peninsula of India, and which consequently omits the more interesting types found in Assam, Burmah, and Ceylon, as well as the countries bordering the British Indian Empire on the North. The geographical limits of the present work have been extended to all territories likely to be reached by the sportsman from India, thus greatly enlarging the field of its usefulness...

The Journals of Robert Falcon Scott by Robert Falcon Scott The Journals of Robert Falcon Scott

Capt. Robert F. Scott's bid to be the leader of the first expedition to reach the South Pole is one of the most famous journeys of all time. What started as a scientific expedition turned out to be an unwilling race against a team lead by R. Admunsen to reach the Pole. The Norwegian flag already stood at the end of the trail when Scott's party reached their target. All the five men of the Scott expedition who took part in the last march to the Pole perished on their way back to safety. Robert F. Scott kept a journal throughout the journey, all the way to the tragic end, documenting all aspects of the expedition...

The Surprising Adventures of Bampfylde Moore Carew recounts the wide-ranging exploits of a real-life rogue – a wily professional mendicant who roams 18th-century England extracting charity from merchants, clergyman, and members of the landed gentry alike, employing in his craft an ingenious variety of deceptions and disguises put on for the purpose. Often he impersonates a shipwreck-surviving seaman and uses his wide knowledge of foreign parts and personages to achieve plausibility. Or he might appear on a doorstep as a destitute woman in widow's weeds, toting borrowed babes to enhance the effect...
