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...

A TRIBUTE It is an accepted truth, I believe, that every novelist embodies in the personalities of his heroes some of his own traits of character. Those who were intimately acquainted with William Otis Lillibridge could not fail to recognize this in a marked degree. To a casual reader, the heroes of his five novels might perhaps suggest five totally different personalities, but one who knows them well will inevitably recognize beneath the... more...

I am a bachelor uncle. That, as a mere fact, might happen to anybody; but I am a bachelor uncle by internal fitness. I am one essentially, just as I am an individual of the Caucasian division of the human race; and if, through untoward circumstances—which Heaven forbid—I should lose my present position, I shouldn't be surprised if you saw me out in the "Herald" under "Situations Wanted—Males." Thanks to a marrying tendency in... 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...
