الصفحة 111 - Agriculture, the general designs and duties of which shall be to acquire and to diffuse among the people of the United States useful information on subjects connected with agriculture in the most general and comprehensive sense of that word, and to procure, propagate, and distribute among the people new and valuable seeds and plants.
الصفحة 26 - The successful application of steam power to farm work, is a desideratum — especially a steam plow. It is not enough that a machine operated by steam, will really plow. To be successful, it must, all things considered, plow better than can be done with animal power. It must do all the work as well, and cheaper: or more rapidly, so as to get through more perfectly in season; or in some way afford an advantage over plowing with animals, else it is no success.
الصفحة 12 - The land-side and the standard were made of wood, and it had a wooden mold-board, often roughly plated over with pieces of old saw-plate, tin, or sheet-iron. It had a clumsy wrought-iron share, while the handles were upright, held in place by two wooden pins. It took a strong man to hold it, and about double the strength of team now required to do the same amount of work. The 'barshare plow,' sometimes called the 'bullplow,
الصفحة 321 - Mr. FABRICANT. Yes; put in language that other people will understand. Information on all resources is not available, however. Until rather recently, economists interested in measuring the rate of increase in national productivity had to make shift with labor input alone — first, in terms of number of workers, then in terms of number of man-hours. This is still true for most individual industries, narrowly defined, even on an historical basis, and for both individual industries and the economy...
الصفحة 111 - A dozen fields of thought are today congested with knowledge that the physical and social sciences have unearthed, and the whole tone and temper of American life can be lifted by putting this knowledge into general circulation. But where are the interpreters with the training and the willingness to think their way through this knowledge and translate it into the language of the street? I raise the recruiting trumpet for the interpreters.
الصفحة 103 - In enacting this new legislation, we have made it our national policy 'that adequate telephone service be made generally available in rural areas through the improvement and expansion of...
الصفحة 111 - The future of America is in the hands of two men — the investigator and the interpreter. We shall never lack for the administrator, the third man needed to complete this trinity of social servants. And we have an ample supply of investigators, but there is a shortage of readable and responsible interpreters, men who can effectively play mediator between specialist and layman.
الصفحة 13 - ... century, amounts to many millions of dollars a year in the cost of teams, and some millions in the cost of plows, or that the aggregate of crops has been increased by them many millions of bushels. The plow has also been modified to adapt it to a much greater variety of soils. In the mode of manufacture, too, a vast improvement has taken place. Half a century ago it was made sometimes on the farm, sometimes by the village blacksmith, and the wheelwright. The work is now concentrated in fewer...
الصفحة 11 - One of the chief obstacles the early colonists had to encounter, to add to the hardships of their lot in the cultivation of the soil, was the difficulty of procuring suitable implements. A few, no doubt, were brought with them, but all could not obtain them in. this way, and the only metal they had was made of bog-ore, and that was so brittle as to break easily and put a stop to their day's work. Most of their tools were made of wood, rude enough in construction, heavy of necessity, and little fit...
الصفحة 13 - But perhaps the most important of modern agricultural inventions are the grain-harvesters, the reapers, the mowers, the threshers, and the horse-rakes. The sickle, which was in almost universal use till within a very recent date, is undoubtedly one of the most ancient of all our farming implements. Reaping by the use of it was always slow and laborious, while from the fact that many of our grains would ripen at the same time, there was a liability to loss before they could be gathered, and practically...
