 And yet these are but few of the many operations of farming, valuable in themselves, and economical of that most costly of all things to him—his horse power; five fingers shoes he cannot use steam for his great operations, as ploughing, sowing, harrowing, rolling, mowing, carting, stacking, &c. In the meantime, however, he is getting his work done pretty well by some locomotive or fixture, whether future invention is or is not further to help him.We well remember the wonder with which the portable farm steam-engine was viewed at the Liverpool Meeting of the Royal Agricultural Society. vibram five fingers It was then a very imperfect implement, and a very different one, to what is now turned out. From that year (1841), there have been vast strides made, and the close competition and severe tests adopted by the Royal, the Yorkshire, the Lincolnshire, and other agricultural societies, as well as the vast trade done in locomotive agricultural steamengines, show how the agricultural mind is opening to their advantages, and how mechanical talent is being exerted to meet these wants. vibram fivefingers Taking the twelve steam-engines of the portable kind, which were put to the test by the Royal Agricultural Society at Gloucester, last year, would itbe believed that there could one be found which would get up its steam in 33 minutes, and for this consumed only 31 lbs. of coal ? vibram five fingers sale An investigation might perhaps determine that the economy of fuel had no connexion with this short period of time in getting up the steam, and that the proportionate quantity of water in the boiler might be even less than that in the other boilers where the average of time in getting up the steam did not exceed 45 minutes; vibram five fingers shoes still the result is deserving of record. The most surprising fact, however, was the small amount of coal per horse-power per hour expended, to produce which effect some of the engines, where the economy was greatest, had somewhat complicated valve gear; but a caution has now been properly given to pay attention in future rather to simplicity of arrangement, proportion, and accessibility, than to any twopenny saving in coal; and this is the real light in which to look at them, after a certain minimum is obtained. Selecting five of those which consumed the smallest quantity, we have—Now, assuming them all, for argument sake, to be six-horse power engines, and that they worked 10 hours per day, the quantity of coals would be (omitting fractions)—Taking engine coals to be worth about 13s. 4d. per ton, it is just 8d. per cwt. or Id. per stone. vibram five fingers kso Between the highest and the second engine in consumption of coal per day, assuming both to be sixhorse power engines, there is a difference of 30lbs. —a very small fraction short of 2d. per day difference ; while between the highest and the lowest on the list, there is a difference of little more than a hundred-weight, and not exceeding 9d. per day extra.At Gloucester, Mr. Amos, the consulting engineer of the Society, placed the improvement in steam-engines in a very powerful light.
