      Far behind them in their swift chase, with every ounce of power put into their engine and their whole hearts urging it to better speed, the Sky Patrol saw the amphibian swerve toward shore and give up the try for whatever that precious life preserver had attached to it.Wind-power, aside from the objections of uncertainty and irregularity, is the cheapest kind of motive-power. Steam machinery, besides costing a large sum as an investment, is continually deteriorating in value, consumes fuel, and requires continual skilled attention. Water-power also requires a large investment, greater in many cases than steam-power, and in many places the plant is in danger of destruction by freshets. Wind-power is less expensive in every way, but is unreliable for constancy except in certain localities, and these, as it happens, are for the most part distant from other elements of manufacturing industry. The operation of wind-wheels is so simple and so generally understood that no reference to mechanism need be made here. The force of the wind, moving in right lines, is easily applied to producing rotary motion, the difference from water-power being mainly in the comparative weakness of wind currents and the greater area required in the vanes upon which the wind acts. Turbine wind-wheels have been constructed on very much the same plan as turbine water-wheels. In speaking of wind-power, the propositions about heat must not be forgotten. It has been explained how heat is almost directly utilised by the steam-engine, and how the effect of heat is utilised by water-wheels in [42] a less direct manner, and the same connection will be found between heat and wind-wheels or wind-power. Currents of air are due to changes of temperature, and the connection between the heat that produces such air currents and their application as power is no more intricate than in the case of water-power.



      At Blauwput, near Louvain, where, according to the Germans, there had been also shooting, many houses were set on fire and the men placed in a row. It was then announced that by way of punishment every fifth man would be shot. When the Germans counted as tenth the father of a large family, that man fainted, and they simply killed number eleven, a Capuchin.It was that way when I looked before, Sandy said. That was why I didnt think anybody meant to use it

      They sang and shouted and waved their arms. Most of them carried bottles full of liquor, which they put to their mouths frequently, smashed them on the ground, or handed them to their comrades, when unable to drink any more themselves. Each of a troop of cavalry had a bottle of pickles, and enjoyed them immensely.In England and America the evils which arise from a false or over estimate of mere theoretical knowledge have thus far been avoided. Our workshops are yet, and must long remain, our technological schools. The money value of bare theoretical training is so fast declining that we may be said to have passed the point of reaction, and that the importance of sound practical knowledge is beginning to be more felt than it was some years ago. It is only in those countries where actual manufactures and other practical tests are wanting, that any serious mistake can be made as to what should constitute an education in mechanics. Our workshops, if other means fail, will fix such a standard; and it is encouraging to find here and there among the outcry for technical training, a note of warning as to the means to be employed.


      With Bacon, experience was the negation of mere authority, whether taking the form of natural prejudice, of individual prepossession, of hollow phrases, or of established systems. The question how we come by that knowledge which all agree to be the most certain, is left untouched in his logic; either of the current answers would have suited his system equally well; nor is there any reason for believing that he would have sided with Mill rather than with Kant respecting the origin of mathematical axioms. With Locke, experience meant the analysis of notions and judgments into the simple data of sense and self-consciousness; and the experientialists of the present day are beyond all doubt his disciples; but the parentage of his philosophy, so far as it is simply a denial of innate ideas, must be sought, not in the Novum Organum, nor in any other modern work, but in the old Organon of Aristotle, or in the comments of the396 Schoolmen who followed Aristotle in protesting against the Platonism of their time, just as Locke protested against the Platonism of Descartes and Malebranche.

      May all the nations of the world after the war collaborate to compensate Louvain for her martyrdom, see that this city shall be restored to her former, happy prosperity, and get a library which approaches as much as possible the one she lost. The Germans can probably do their part by investigating where the motor-cars went which left the Halls on that wretched Tuesday night, heavily laden with books.402

      In the class of mechanical knowledge that has been defined as general, construction comes in the third place: first, machine functions; next, plans or adaptation of machines; and third, the manner of constructing machines. This should be the order of study pursued in learning mechanical manipulation. Instead of studying how drilling-machines, planing-machines or lathes are arranged, and next plans of constructing them, and then the principles of their operation, which is the usual course, the learner should reverse the order, studying, first, drilling, planing, and turning as operations; next, the adaptation of tools for the purposes; and third, plans of constructing such tools."Right as usual, Mr. Lawrence," said Prout, beaming approvingly on the great novelist. "Why don't you come and join the force?"
