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... more...

CHAPTER I. THE INCEPTION OF THE GRANGE When President Johnson authorized the Commissioner of Agriculture, in 1866, to send a clerk in his bureau on a trip through the Southern States to procure "statistical and other information from those States," he could scarcely have foreseen that this trip would lead to a movement among the farmers, which, in varying forms, would affect the political and... 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...

CHAPTER I. THE INTRODUCTION OF AIRCRAFT INTO MILITARY OPERATIONS It is a curious circumstance that an invention, which is hailed as being one of the greatest achievements ever recorded in the march of civilisation, should be devoted essentially to the maiming of humanity and the destruction of property. In no other trend of human endeavour is this factor so potently demonstrated as in connection with... more...

FOREWORD Once in awhile, maybe, twenty-five or thirty years ago, they used to pack you off during the holidays for a visit on Somebody's Farm. Have you forgotten? You went with your little round head close clipped till all the scar places showed white and you came back with a mat of sunbleached hair, your face and hands and legs brown as a nut. Probably you treasure recollections of those boyhood... more...

DEFINITIONS DEFIN. I. By the Rays of Light I understand its least Parts, and those as well Successive in the same Lines, as Contemporary in several Lines. For it is manifest that Light consists of Parts, both Successive and Contemporary; because in the same place you may stop that which comes one moment, and let pass that which comes presently after; and in the same time you may stop it in any one... more...

Agriculture in Virginia, 1607-1699 Various events in the latter years of the sixteenth century did much to shape the future destiny of the English nation. With the destruction of the Spanish Armada in 1588, England rose from a minor position in world affairs to one of major importance. One of the first changes was reflected in her attitude towards trade and commerce. England was no longer penned up on... more...

Chapter I. INTRODUCTION. In the last three hundred years there have been many questions of general interest before the American people. It is doubtful, however, if there is another problem, which is as warmly debated to-day as ever and whose solution is yet so uncertain, as that of the Negro. In the second decade of the seventeenth century protests were being filed against black slavery, but the system... 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... more...

Introduction This report has been undertaken for a special reason. It is to explain to the taxpayer just why so many of his dollars are going into the American effort to explore space, and to indicate what he can expect in return which is of value to him. Such an explanation, even after 2 years of relatively high-geared activity in the space exploration field, appears to be warranted. There is still a... more...
