INTRODUCTION THE Germans interpret their new national colours—black, red, and white—by the saying, "Durch Nacht und Blut zur licht." ("Through night and blood to light"), and no work yet written conveys to the thinker a clearer conception of all that the red streak in their flag stands for than this deep and philosophical analysis of "War" by Clausewitz.

THE FARMER AT HOME. The new towns, or suburbs which spring up every year in the neighbourhood of London, are all built upon much the same plan. Whole streets of houses present exact duplicates of each other, even to the number of steps up to the front door and the position of the scraper. In the country, where a new farmhouse is erected about once in twenty years, the styles of architecture are as... more...

HOW NEWSPAPERS ARE MADE. We will suppose that it is a great newspaper, in a great city, printing daily 25,000, or more, copies. Here it is, with wide columns, with small, compact type, with very little space wasted in head lines, eight large pages of it, something like 100,000 words printed upon it, and sold for four cents—25,000 words for a cent. It is a great institution—a power greater than a... more...

APPARATUS 1. 1. Carbon-Zinc Cell. Fig. 1. If you have some rubber bands you can quickly make a cell out of rods of zinc and carbon.

THE FRANCO-AMERICAN CORPS It was on a cool, starlit evening, early in September, 1916, that I first met Drew of Massachusetts, and actually began my adventures as a prospective member of the Escadrille Américaine. We had sailed from New York by the same boat, had made our applications for enlistment in the Foreign Legion on the same day, without being aware of each other's existence; and in... more...

In this rude monument for ages be recorded this wondrous enterprise... more...

INTRODUCTION Students of economics know that the roundabout methods of capitalistic production are far more fruitful than the direct methods of the primitive economy. As we advance, we introduce new intermediaries between the beginning and the end of production. This thought occurs to one in the study of Americanization. If we would Americanize the immigrant we must seek him out in his daily economic... more...

CHAPTER I. THE DAWN OF AERONAUTICS. "He that would learn to fly must be brought up to the constant practice of it from his youth, trying first only to use his wings as a tame goose will do, so by degrees learning to rise higher till he attain unto skill and confidence." So wrote Wilkins, Bishop of Chester, who was reckoned a man of genius and learning in the days of the Commonwealth. But so... more...

Mr. President, and Members of the "Central Mich. Ag'l Society:" Ladies and Gentlemen: Remote from the theatre of action in the late rebellion, Michigan has experienced comparatively few of the evils that followed immediately in its path. The usual pursuits of peaceful life, were here scarcely disturbed, and by the permission of a Gracious Providence, the industry of the inhabitants of our... more...

FOREWORD We are not tied to a desk or to a bench; we stay there only because we think we are tied. In Montana I had a horse, which was hobbled every night to keep him from wandering; that is, straps joined by a short chain were put around his forefeet, so that he could only hop. The hobbles were taken off in the morning, but he would still hop until he saw his mate trotting off. This book is intended... more...
