THEORIES OF TUITION Only eight years ago, in 1908, it was declared impossible for one man to teach another to fly. Those few men who had risen from the ground in aeroplanes, notably the Wright brothers, were held to be endowed by nature in some very peculiar way; to be men who possessed some remarkable and hitherto unexplained sense of equilibrium. That these men would be able to take other men—ordinary members of the human race—and... more...

In an inventive tour de force that seldom, if ever, has been equalled for its brilliance and far-reaching consequences, James Watt radically altered the steam engine not only by adding a separate condenser but by creating a whole new family of linkages. His approach was largely empirical, as we use the word today. This study suggests that, despite the glamor of today's sophisticated methods of calculation, a highly developed intuitive sense,... more...

CHAPTER I. EVOLUTION OF TWO-SURFACE FLYING MACHINE. By Octave Chanute. I am asked to set forth the development of the "two-surface" type of flying machine which is now used with modifications by Wright Brothers, Farman, Delagrange, Herring and others. This type originated with Mr. F. H. Wenham, who patented it in England in 1866 (No. 1571), taking out provisional papers only. In the abridgment of British patent Aeronautical Specifications... 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 to show how any one can trot off if he... more...


CHAPTER I ESSENTIALS OF SUCCESS Columella, the much traveled Spanish-Roman writer of the first century A. D., said that for successful farming three things are essential: knowledge, capital and love for the calling. This statement is just as true today as it was when written 1900 years ago by this early writer on European agriculture. Every man who loves the calling and has an ambition to become a successful farmer should understand that no... more...

ANNOUNCER In the year 1661 Connecticut received from the hand of Charles the Second a very liberal charter granting to the people of the colony almost complete self-government and to the colony an enormous stretch of territory extending westward to the Pacific Ocean. For fifteen years the colony prospered under the generous charter. Then in 1676 trouble arose with the Governor of New York, Sir Edmund Andros, about the boundary line between the... more...

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 varied and as irregular as in town they are prim... more...

Our ambitious young commonwealth, in conjunction with other states comprising the great Northwest, occupies a commanding position in the industrial and economic affairs of this nation. Mines of gold and silver or forests primeval North Dakota does not have; but from the millions of fertile acres comprising our vast agricultural empire, we may reap a golden harvest every year that will exceed in wealth the output of all the golden placers in the... more...
