Page v - Nevertheless he can use Tools, can devise Tools: with these the granite mountain melts into light dust before him; he kneads glowing iron, as if it were soft paste; seas are his smooth highway, winds and fire his unwearying steeds. Nowhere do you find him without Tools: without Tools he is nothing, with Tools he is all.
Page 146 - I had great difficulty- in proving that the machine had 'been used in Georgia, although, at the same moment, there were three separate sets of this machinery in motion within fifty yards of the building in which the court sat, and all so near that the rattling of the wheels was distinctly heard on the steps of the courthouse.
Page 124 - An improvement is made here in the construction of muskets, which it may be interesting to Congress to know, should they at any time propose to procure any. It consists in the making every part of them so exactly alike, that what belongs to any one, may be used for every other musket in the magazine.
Page 237 - The time will come when people will travel in stages, moved by steam engines, from one city to another, almost as fast as birds fly, fifteen or twenty miles an hour.
Page xviii - Small wonder ! for we find him complaining that in an 18-inch diameter cylinder, " at the worst place the long diameter exceeded the short by threeeighths of an inch." When Smeaton first saw the engine he reported to the Society of Engineers that " neither the tools nor the workmen existed that could manufacture so complex a machine with sufficient precision.
Page v - Man is a Tool-using Animal (Handthierendes Thier). Weak in himself, and of small stature, he stands on a basis, at most for the flattest-soled, of some half-square foot, insecurely enough; has to straddle out his legs, lest the very wind supplant him. Feeblest of bipeds ! Three quintals are a crushing load for him; the steer of the meadow tosses him aloft, like a waste rag.
Page 152 - Is there a man who hears us who has not experienced its iltility? the whole interior of the southern states was languishing, and its inhabitants emigrating for want of some object to engage their attention and employ their industry, when the invention of this machine at once opened views to them which set the whole country in active motion.
Page 145 - The difficulties with which I have to contend have originated, principally, in the want of a disposition in mankind to do justice. My invention was new and distinct from every other ; it stood alone. It was not interwoven with anything before known ; and it can seldom happen that an invention or improvement is so strongly marked and can be so clearly and specifically identified ; and I have always believed that I should have no difficulty in causing my right to be respected, if it had been less valuable,...
Page 152 - Individuals who were depressed with poverty, and sunk in idleness, have suddenly risen to wealth and respectability. Our debts have been paid off. Our capitals have increased, and our lands trebled themselves in value. We cannot express the weight of the obligation which the country owes to this invention. The extent of it cannot now be seen.
Page 8 - ... bore, and shape, with a degree of certainty almost amounting to mathematical precision. The mechanical operations of the present day could not have been accomplished at any cost thirty years ago, and what was considered impossible at that time, is now performed with a degree of intelligence and exactitude that never fail to accomplish the end in view...
