PREFACE TO THE FIRST EDITION. (1872) It is not without hesitation that I have taken upon myself the editorship of a work left avowedly imperfect by the author, and, from its miscellaneous and discursive character, difficult of completion with due regard to editorial limitations by a less able hand. Had the author lived to carry out his purpose he would have looked through his Budget again, amplifying and probably rearranging some of its... more...

The Committee on English Research of the New England Historic Genealogical Society called attention in their last annual report to the fact that there were in England many important documents relating to the American colonies, as well as manuscript maps hitherto unknown to historical investigators. They urged upon the society the desirability of having exact copies of them made now while we have in Mr. Henry Fitz-Gilbert Waters an experienced... more...

TORPEDOES Torpedoes as effective weapons in actual war were first utilized by the Confederate navy, and Captain Matthew F. Maury introduced them into that service, and continually improved and perfected their use until they had become the mighty engine of modern warfare and revolutionized the art of coast and harbour defense. He, it was, who in 1861 mined James River, who, in person commanded the first attack with torpedoes upon the Federal... more...

BRIEF MEMOIR OF ELIZA SOUTHALL. Eliza Southall, wife of William Southall, Jr., of Birmingham, England, and daughter of John and Eliza Allen, was born at Liskeard, on the 9th of 6th month, 1823. As she felt a strong attachment to the scenes of her childhood, and an interest in the people among whom she spent the greater part of her short life,—an attachment which is evinced many times in the course of her memoranda,—it may interest... more...

EARLY DISCOVERIES AND SETTLEMENTS. [Illustration: BALBOA.] GEOGRAPHICAL KNOWLEDGE IN THE FIFTEENTH CENTURY.—The people of Europe had then never heard of America. About that time, a great desire for geographical knowledge was awakened. The compass and the astrolabe—an instrument for reckoning latitude—had been already invented. Voyagers were no longer compelled to creep along the shore, but began to strike out boldly into the... more...


It is well known that the number of elements has grown from four in the days of the Greeks to 103 at present, but the change in methods needed for their discovery is not so well known. Up until 1939, only 88 naturally occurring elements had been discovered. It took a dramatic modern technique (based on Ernest O. Lawrence's Nobel-prize-winning atom smasher, the cyclotron) to synthesize the most recently discovered elements. Most of these recent... more...

CHAPTER I DISCOVERY OF RADIO-ACTIVITY The object of this brief treatise is to give a simple account of the development of our knowledge of radio-activity and its bearing on chemical and physical science. Mathematical processes will be omitted, as it is sufficient to give the assured results from calculations which are likely to be beyond the training of the reader. Experimental evidence will be given in detail wherever it is fundamental and... more...

CHAPTER I "God bless them all! they are good lads." It was now close on eight o'clock and more than two hours ago since first the dawn broke over that low-lying horizon line which seems so far away, and tinged the vast immensity of the plain first with grey and then with mauve and pale-toned emerald, with rose and carmine and crimson and blood-red, until the sun—triumphant and glorious at last—woke the sunflowers from their sleep,... more...

CHAPTER I It was the last of May in the north of England, in the year 1209. A very different England from what any boy of to-day has seen. A chilly east wind was blowing. The trees of the vast forests were all in leaf but the ash trees, and they were unfolding their buds. And along a bridle-path a few miles southwest of York a lad of fourteen was riding, while behind him followed a handsome deerhound. A boy of fourteen, at that age of the world,... more...

Chapter I Cross-Roads IT was late November and a little snow had fallen. Three boys were on their way down Park Avenue to school—the Regal High. One of the boys, Frank Mulvy, carried his lunch in his pocket. He did not live far away, but his mother was to be out for the day and had put up a lunch for him. As the boys came down the avenue, an old man whom they had never seen before, met them. He asked them for a few cents to get something... more...
