THREE:What happened? Who done this? repeated Jeff.
FORE:A gravity wheel must have a diameter equal to the fall of water, or, to use the technical name, the height of the head. The speed at the periphery of the wheel cannot well exceed sixteen feet per second without losing a part of the effect by the wheel anticipating or overrunning the water. This, from the large diameter of the wheels, produces a very slow axial speed, and a train of multiplying gearing becomes necessary in order to reach the speed required in most operations where power is applied. This train of gearing, besides being liable to wear [38]and accident, and costing usually a large amount as an investment, consumes a considerable part of the power by frictional resistance, especially when such gearing consists of tooth wheels. Gravity wheels, from their large size and their necessarily exposed situation, are subject to be frozen up in cold climates; and as the parts are liable to be first wet and then dry, or warm and cold by exposure to the air and the water alternately, the tendency to corrosion if constructed of iron, or to decay if of wood, is much greater than in submerged wheels. Gravity wheels, to realise the highest measure of effect from the water, require a diameter so great that they must drag in the water at the bottom or delivering side, and are for this reason especially affected by back-water, to which all wheels are more or less liable from the reflux of tides or by freshets. These disadvantages are among the most notable pertaining to gravity wheels, and have, with other reasonssuch as the inconvenience of construction, greater cost, and so ondriven such wheels out of use by the force of circumstances, rather than by actual tests or theoretical deductions.

FORE:The physics of Stoicism was, in truth, the scaffolding rather than the foundation of its ethical superstructure. The real foundation was the necessity of social existence, formulated under the influence of a logical exclusiveness first introduced by Parmenides, and inherited from his teaching by every system of philosophy in turn. Yet there is no doubt that Stoic morality was considerably strengthened and steadied by the support it found in conceptions derived from a different order of speculations; so much so that at last it grew to conscious independence of that support.

FORE:Finishing and fitting relates to giving true and accurate dimensions to the parts of machinery that come in contact with each other and are joined together or move upon each other, and consists in cutting away the surplus material which has to be left in founding and forging because of the heated and expanded condition in which the material is treated in these last processes. In finishing, material is operated upon at its normal temperature, in which condition it can be handled, gauged, or measured, and will retain its shape after it is fitted. Finishing comprehends all operations of cutting and abrading, such as turning, boring, planing and grinding, also the handling of material; it is considered the leading department in shop manipulation, because it is the one where the work constructed is organised and brought together. The fitting shop is also that department to which drawings especially apply, and other preparatory operations are usually made subservient to the fitting processes.So much only is established in the Physics. Further particulars are given in the twelfth book of the Metaphysics. There we learn that, all movement being from possibility to actuality, the source of movement must be a completely realised actualitypure form without any admixture of matter. But the highest form known to us in the ascending scale of organic life is the human soul, and the highest function of soul is reason. Reason then must be that which moves without being moved itself, drawing all things upwards and onwards by the love which its perfection inspires. The eternal, infinite, absolute actuality existing beyond the outermost starry sphere is God. Aristotle describes God as the thought which thinks itself and finds in the simple act of self-consciousness an everlasting happiness, wonderful if it always equals the best moments of our mortal life, more wonderful still if it surpasses them. There is only one supreme God, for plurality is due to an admixture of matter, and He is pure form. The rule of many is not good, as Homer says. Let there be one Lord.
