When the pace of railroad construction slackened in 1914, Canada had achieved a remarkable position in the railway world. Only five other countries—the United States, Russia, Germany, India, and, by a small margin, France—possessed a greater mileage; and, relatively to population, none came anywhere near her. This is the story of how Canada became a country stitched together by rail.

Airlords of Han is the 2nd Buck Rogers story, the sequel to Armageddon 2419 A.D.. Anthony Rogers takes the fight to free 25th Century America to the Han overlords. From the March, 1929 issue of Amazing Stories.

It was the 34th century and all five of the Federation of Planets around Sol were buzzing with their usual activity when the Raiders appeared. They were indeed Raiders of Universes because they had ravaged many systems before reaching Earth and showed no signs of slowing down in the least. Their weapons were invincible, their greed merciless and their natures completely alien. Indeed 'they' were from another dimension entirely. Eating up entire solar systems and planets, they slowed down just a bit when intelligent life was found on Earth...

Plain speaking is necessary in any discussion of religion, for if the freethinker attacks the religious dogmas with hesitation, the orthodox believer assumes that it is with regret that the freethinker would remove the crutch that supports the orthodox. And all religious beliefs are "crutches" hindering the free locomotive efforts of an advancing humanity. There are no problems related to human progress and happiness in this age which any theology can solve, and which the teachings of freethought cannot do better and without the aid of encumbrances.

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...

This investigation of Bacon the scholar and man of letters begins with a look at the early days ang progresses to his relationships with Queen Elizabeth and James I. It includes accounts of his positions as solicitor general, attorney-general, and chancellor. The book concludes with Bacon's failure, his overall philosophy, and summaries of his writings.

This book, with the subtitle "Across the Continent of South America" describes the scientific expedion of 1867 to the equatorial Andes and the Amazon. The route was from Guayaquil to Quito, over the Cordillera, through the forest to Napo, and, finally, on the Rio Napo to Pebas on the Maranon. Besides this record, the expedition - under the auspices of the Smithsonian Institute - collected samples of rocks and plants, and numerous specimen of animals. The scientists also compiled a vocabulary of local languages and produced a new map of equatorial America...

A world weary space pilot on the lam from earth for crimes unspecified; the most beautiful (earthly) tri-D woman in the universe who is determined to be the most powerful too; a planet of crafty and unscrupulous giant frogs intent on kicking out all aliens; and finally beings who live outside of time. Mix them all together and some very interesting things happen. Very interesting. And disastrous. But there's more! Why did 3000 worlds across the galaxy suddenly blossom almost simultaneously with very similar life and intelligence? Could there have been a common ancestor? Well, give or take a million years, simultaneously...

Three Science Fiction stories by the great Gerald Vance: Monsoons of Death is a very nice blend of horror story and a study of true bravery on the planet Mars. A newly commissioned lieutenant finds out a lot about both! In Larson's Luck, Vance takes us on a light hearted jaun into hot shot space ship pilots, piracy and the good part of breaking the rules. The last story, Vital Ingredient, takes the listener far into the future when the sport of boxing still has two musceled opponents battling it out in a ring, but they are simply puppets, every muscle, feint and jab controlled by ring side 'managers'; ex fighters who have moved up...

INFLUENCES OF GEOGRAPHIC ENVIRONMENT ON THE BASIS OF RATZEL'S SYSTEM OF ANTHROPO-GEOGRAPHY BY ELLEN CHURCHILL SEMPLE PREFACE The present book, as originally planned over seven years ago, was to be a simplified paraphrase or restatement of the principles embodied in Friedrich Ratzel's _Anthropo-Geographie_. The German work is difficult reading even for Germans. To most English and American students of geographic environment it is a closed book, a treasure-house bolted and barred. Ratzel himself realized that any English form could not be a literal translation, but must be adapted to the Anglo-Celtic and especially to the Anglo-American mind...

Numerous theories have been proposed for the causes of dancing mania, and it remains unclear whether it was a real illness or a social phenomenon. One of the most prominent theories is that victims suffered from ergot poisoning, which was known as St Anthony’s Fire in the Middle Ages. During floods and damp periods, ergots were able to grow and affect rye and other crops. Ergotism can cause hallucinations, but cannot account for the other strange behaviour most commonly identified with dancing mania...

“The martyrs of Science” gives a brief biography of Galileo, Brahe and Kepler. These three men played a pivotal role in the scientific revolution during the early modern period. This book throws light upon their lives, their scientific achievements, adversities which they faced for their work and how they transformed the lives of the future generations forever. It also provides evidence which establishes that the work carried out by them are original irrespective of the claims by other men who tried in vain to rob them of their honor. The author highlights some of their fallacies which hindered their progress.

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...

" Believing that the woman's claim to a common humanity is not an unreasonable one, and that the successful issue of such claim rests primarily upon the sense of fair play which people have or have not according to how they were born, and Therefore to men and women everywhere who love a fair deal, and are willing to give it to everyone, even women, this book is respectfully dedicated by the author."

G.L.Vandenburg wrote quirky and funny Science Fiction stories for Amazing Science Fiction Stories, and similar magazines in the 1950's. These four are a selection that give a good taste of his offbeat approach, strange sense of humor and relaxed narrative style that brought joy and excitement to those of us who bought these magazines and saw his name on the cover. In the first, Martian V.F.W., some strange visitors join a parade; in the second, Jubilation, U.S.A, our first visitors from outer space...

This biography of Johannes Kepler begins with an account of what the world of astronomy was like before his time, then proceeds to a look at his early years. Two chapters deal with his working relationship with Tycho Brahe. These are followed by a look at Kepler's laws and his last years.

"On that bright spring afternoon when three happy, interested children went off to the woods with their governess to take their first lesson in the study of wild flowers, they saw also some other things which made a fresh series of "Elmridge Talks," and these things were found among the trees of the roadside and forest."

Though little is known about its author, this is considered the first vegan cookbook ever written. At the time of its composition, the Vegetarian Society and other advocates of vegetarian diets were engaged in a debate about the inclusion of dairy and eggs in one's regime. This text declares, from the title to the footnotes, that the best diet is free from all animal products. The arguments span historical, physical, ethical, aesthetic, and economic considerations and conclude with practical advice that stands the test of time. An essential text for those interested in vegetarianism and animal rights.

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)

Presented in the form of lessons, R. Cadwallader Smith vividly portrays life in the ocean. Learn about the common and not so common that swim about in the deep, how they hunt for food and hide from enemies, visit a nursery and find out about the babies that live there, or take a stroll in an underwater garden.

"Histories are more full of examples of the fidelity of dogs than of friends."The character, sensibilities, and intellectual faculties of animals have always been a favourite study, and they are, perhaps, more strongly developed in the dog than in any other quadruped, from the circumstance of his being the constant companion of man. I am aware how much has been written on this subject, but having accumulated many original and interesting anecdotes of this faithful animal, I have attempted to enlarge the general stock of information respecting it...

"The long war has brought hunger to Europe; some of her peoples stand constantly face to face with starvation. To meet all this great food need in Europe—and meeting it is an imperative military necessity—we must be very careful and economical in our food use here at home. We must eat less; we must waste nothing; we must equalize the distribution of what food we may retain for ourselves; we must prevent extortion and profiteering which make prices so high that the poor cannot buy the food they actually need; and we must try to produce more food...

The Flying Saucers are Real is a book that investigates numerous encounters between USAF fighters, personnel, and other aircraft, and UFOs between 1947 and 1950. Keyhoe contended that the Air Force was actively investigating these cases of close encounter, with a policy of concealing their existence from the public until 1949. He stated that this policy was then replaced by one of cautious, progressive revelation. Keyhoe further stated that Earth had been visited by extraterrestrials for two centuries, with the frequency of these visits increasing sharply after the first atomic weapon test in 1945...

How do elephants drink? What is the Law of the Jungle at the water hole? How does an elephant baby learn to feed and learn to swim? How do they walk under water? In what order do buffaloes drink? How do buffaloes fight the tiger? These and other wild inhabitants of the Indian jungle such as pigs, wild dogs, deer, camels, bears and birds are discussed in lively stories to entertain but mainly educate children of school age. "One of the great thinkers of the world has said that all the sciences are embodied in natural history...

A Handbook for Women During Pregnancy. This book, written for women who have no special knowledge of medicine, aims to answer the questions which occur to them in the course of pregnancy. Directions for safeguarding their health have been given in detail, and emphasis has been placed upon such measures as may serve to prevent serious complications. (Introduction by J. Morris Slemons)

George Muller was a great hero of faith. His greatest aim was to demonstrate that God answers prayer and can be trusted for every minute detail of life. Spending countless hours asking God to provide his needs, he only relied upon God. God called him to care for orphans and he conducted his orphanage in the same way, on faith alone. When a certain need was apparent, they would immediately go to God in prayer. In this dynamic dependance on God, He always proved faithful. He also established over a hundred schools, educating over a hundred thousand people! His example of absolute dependence on God stands in the gap of history to declare that God is enough, and He is faithful!

This post-apocalyptic novella tells the story of the downfall of civilisation and mankind following a solar cataclysm in the late 20th century. To survive, the remnants of humanity had to build a new civilization underground in the complete absence of all species except mankind, choosing to base it only on love and beauty, the fine arts and intellectual pursuits. In view of the sun's current inactivity, this frighteningly prophetic tale might have been written today, saving that the cultural references and the fluid prose might be beyond, if one dares say so, many modern writers...

The adventures of an Indian boy and his beloved elephant. Born near Calcutta, Mukerji won the Newbury Medal for children's fiction.

"While many scientific men now understand our place in the universe, we electrons are anxious that every person should know the very important part which we play in the workaday world. It was for this reason that my fellow-electrons urged me to write my own biography. I am pleased to say that my relationship with the scribe who has put down my story in the following pages has been of the most friendly description. I have allowed him to place what he calls "The Scribe's Note" at the beginning of each chapter, but it will be understood clearly that these are merely convenient embellishments, and that I am responsible for the story of my own experiences." (Introduction adapted from the text)

The Woodpeckers is a wonderful introduction to the world of bird study for the young naturalist, covering such topics as how he finds food, courting, how he builds his nest, the interesting ways he uses his different body parts as tools, among other topics discussed in the book. If you wish to investigate further, the book has a few diagrams and an Appendix that contains more technical information such as detailed descriptions of the different species of North American woodpeckers which were not read as part of this audiobook.

Wolf's essay considers the homeopathic medicine Apis Mellifica, or the poison of the honey bee, as a therapeutic agent based on his experience as a practicing physician.

Joseph Priestley, FRS (13 March 1733 (O.S.) – 6 February 1804) was an 18th-century English theologian, Dissenting clergyman, natural philosopher, chemist, educator, and political theorist who published over 150 works. In “Experiments and Observations on Different Kinds of Air,” he reviews experiments with gases. A common theme in this work is measuring the volumes of gases held in glass tubes, and their increase or decrease when exposed to other substances. He also tests the effects of gases on mice, plants and insects...

This paper takes the reader through the early settlement from 1783 to the modern period of 1888-1912. We see how farming and farm industries developed and how the population was distributed during these times. We see the trends of settlers moving into the Urban centers instead of rural and how the farm industries (making cheese, butter, wool, etc) move off the farm to the city factories. Excerpt: “The farmer’s wife in those days was perhaps the most expert master of trades ever known. She could spin and weave, make a carpet or a rug, dye yarns and clothes, and make a straw hat or a birch broom...

We have used but little method in the arrangement: Choosing rather to furnish the reader with a rich profusion...

A recording of the first 2000 prime numbers (2-17389). Recommended listening for math fanatics and insomniacs!

Professor Freud developed his system of psychoanalysis while studying the so-called borderline cases of mental diseases, such as hysteria and compulsion neurosis. By discarding the old methods of treatment and strictly applying himself to a study of the patient's life he discovered that the hitherto puzzling symptoms had a definite meaning, and that there was nothing arbitrary in any morbid manifestation. Psychoanalysis always showed that they referred to some definite problem or conflict of the person concerned...

Metaphysics is essentially a reconciliation of Plato’s theory of Forms that Aristotle acquired at the Academy in Athens, with the view of the world given by common sense and the observations of the natural sciences. According to Plato, the real nature of things is eternal and unchangeable. However, the world we observe around us is constantly and perpetually changing. Aristotle’s genius was to reconcile these two apparently contradictory views of the world. The result is a synthesis of the naturalism of empirical science, and the mysticism of Plato, that informed the Western intellectual tradition for more than two thousand years...

"It might seem a little careless to lose track of something as big as a battleship ... but interstellar space is on a different scale of magnitude. But a misplaced battleship—in the wrong hands!—can be most dangerous." The world class con man and thief known as the Stainless Steel Rat (diGriz) has another very big problem to solve and this science fiction novella by the great Harry Harrison will see if he can solve it and perhaps four or five more like it before this fascinating and funny tale is finished. 'Use a thief to catch a thief' sounds great but it sometimes has unexpected results.

The Galactic Empire is slowly 'welcoming' into the family of civilized worlds those systems so far off in the backwater of the galaxy that they have been overlooked and ignored for the past 500 years or so. This is purely routine work because every planet offered the chance has eagerly accepted the invitation. Mainly because the enlightened Empire lets the planetary government continue to rule and do whatever it wants...with a few minor restrictions of course; and because the they are shown what happens to planets who decide not to accept the invitation...

A very wise physician has said that “every illness has two parts—what it is, and what the patient thinks about it.” What the patient thinks about it is often more important and more troublesome than the real disease. What the patient thinks of life, what life means to him is also of great importance and may be the bar that shuts out all real health and happiness. The following pages are devoted to certain ideals of life which I would like to give to my patients, the long-time patients who have especially fallen to my lot.

The human race has reached the stars, colonized many planets and done amazing things in all areas of scientific progress. But humans are still humans and remain both honorable and not so honorable; some with high ideals and others with very low ones indeed. So why hasn't war occurred in several centuries among the hundreds of planets? Has man really changed? Not on your life it hasn't! Read how science has given man peace but at what cost?

Uncontrolled, terribly violent Atomic Vortices are slowly destroying civilization on every human planet throughout the galaxy. Nothing can contain or stop them despite the lensmen's best efforts until one destroys the home and family of "Storm" Cloud, brilliant atomic physicist. The tragedy triggers actions on his part that pit him one-on-one against the horrible vortices. Introducing "storm" Cloud as THE Vortex Blaster

This is a collection of 3 of Harry Harrison marvelous early stories that were published in Galaxy, Analog and Fantastic Universe. The Repairman (1958) is a straight fun SF story of a man getting a job done. It is most typical of his later style in series like the Stainless Steel Rat; Toy Shop (1962), a short piece exploring bureaucratic blindness and one ingenious way around it and The Velvet Glove (1956), my favorite for its writing style, fun perspective, sly social commentary on the scene in 1956 and just plain delightful imagination. And he manages to pack excitement and mystery in at the same time.

Lee Anthony finds himself and two of his friends kidnapped and taken on a strange voyage.

On the Heavens (Greek: Περί ουρανού, Latin: De Caelo or De Caelo et Mundo) is Aristotle's chief cosmological treatise. In it Aristotle argues that the Earth is a sphere by pointing to the evidence of lunar eclipses. Aristotle also provides a detailed explanation of his theory of 'gravity' arguing that things which contain 'earth' fall towards the centre of the Universe because 'earth' is naturally attracted to the centre of the Universe. Aristotle argues that if the planet Earth was moved to the location of the Moon then objects which contain 'earth' would not fall towards the centre of the Earth but rather towards the centre of the Universe...

Can a spaceship go crazy? Well, yes it can if it has a brain. And the new MG (magnetogravitic drive) experimental robot space ship does indeed have a 'brain'. Completely bewildered as to why the first six models of their supposedly perfect new ship model, the MG-YR, nicknamed the McGuire, have gone totally bonkers after activation and before they could ever be used, the company has called in the services of Daniel Oak. They suspect sabotage of course. Daniel Oak is the hard boiled private investigator with nerves of steel and a mind of the same substance...

On Generation and Corruption (Ancient Greek: Περὶ γενέσεως καὶ φθορᾶς, Latin: De Generatione et Corruptione, also known as On Coming to Be and Passing Away) is a treatise by Aristotle. Like many of his texts, it is both scientific and philosophic (although not necessarily scientific in the modern sense). The philosophy, though, is essentially empirical; as in all Aristotle's works, the deductions made about the unexperienced and unobservable are based on observations and real experiences...

Elisha Gray was an American electrical engineer who co-founded the Western Electric Manufacturing Company. Gray is best known for his development of a telephone prototype in 1876 in Highland Park, Illinois and is considered by some writers to be the true inventor of the variable resistance telephone, despite losing out to Alexander Graham Bell for the telephone patent.Nature’s Miracles: Familiar Talks on Science, published in 1900, is a discussion of science and technology for the general public. Volume II is subtitled Energy and Vibration: Energy, Sound, Heat, Light, Explosives.

Wells considered this book one of his most important, a natural follow-up to such works as his Man of the Year Million and The Time Machine. His goal was to get people to think and act in new ways. The book starts with a look at how humans get along socially and how they carry out their business ventures. It then discusses how these elements influence others, such as politics, the world of work, and education. H. G. tried to make clear how the current social order was disintegrating without preparing another to take its place. He then traced the roots of democracy, which in its present state he saw as unworkable. Instead, he proposed a new republic. He also critiqued modern warfare.

This book, written in the mid 19th century and illustrated by Charles H. Bennett, provides an entertaining introduction to topics in science for children. In each chapter, the author uses a popular myth or fairy tale to lay the groundwork for an equally fascinating "fairy tale of science" full of interesting facts and real life examples.
