Introduction The art and science of agriculture embrace most intentional human efforts to control biological activity so as to produce plants and animals of the sort wanted, when wanted. Rubber plantations, cattle ranches, vegetable gardens, dairy farms, tree farms, and a host of similar enterprises all represent human efforts to compel nature to serve man. Those who undertake agriculture have had,... more...

INTRODUCTION Since the earliest communities of human beings first struggled for supremacy and protection, the principles of warfare have remained unchanged. New methods have been evolved and adopted with the progress of science, but no discovery, save perhaps that of gunpowder, has done so much in so short a time to revolutionize the conduct of war as aviation, the youngest, yet destined perhaps to be... more...

CHAPTER I IT IS an old saying that "any fool can farm," and this was almost the truth when farming consisted chiefly in reducing the fertility of new, rich land secured at practically no cost from a generous Government. But to restore depleted soils to high productive power in economic systems is no fool's job, for it requires mental as well as muscular energy; and no apologies should be... more...

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... more...

CHAPTER I. Man's Duel with Nature Of all man's great achievements none is, perhaps, more full of human interest than are those concerned with flight. We regard ourselves as remarkable beings, and our wonderful discoveries in science and invention induce us to believe we are far and away the cleverest of all the living creatures in the great scheme of Creation. And yet in the matter of flight... 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...

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...

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...

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...

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... more...
