TWO:Somebody had found her out. It must be so, because all her plans were anticipated by the terrible antagonist who worked in the dark. Her case was much like that of a despairing criminal who takes one huge sum to conceal the loss of another until the inevitable crash comes.

TWO:"The others have not come yet," he said coolly. "I had arranged for the ceremony to take place without me. I was being detained elsewhere. But behold I am here to take my vengeance in my own hands. When the others come they will be surprised to see their leader again, Beppo."

TWO:"Certainly not," Bruce agreed. "I happen to know an expert who told me so. It took my fancy and I gave ten pounds for it, which, I understand, is about a tenth of its full value."For loading and unloading carts and waggons, the convenience of the old outside sling is well known; it is also a well-attested fact that accidents rarely happen with sling hoists, although they appear to be less safe than running platforms or lifts. As a general rule, the most dangerous machinery for handling or raising material is that which pretends to dispense with the care and vigilance of attendants, and the safest machinery that which enforces such attention. The condition which leads to danger in hoisting machinery is, that the power employed is opposed to the force of gravity, and as the force of gravity is acting continually, it is always ready to take advantage of the least cessation in the opposing force employed, and thus drag away the weight for which the two forces are contending; as a weight when under the influence of gravity is moved [65] at an accelerated velocity, if gravity becomes the master, the result is generally a serious accident. Lifting may be considered a case wherein the contrivances of man are brought to bear in overcoming or opposing a natural force; the imperfect force of the machinery is liable to accident or interruption, but gravity never fails to act. Acting on every piece of matter in proportion to its weight must be some force opposing and equal to that of gravity; for example, a piece of iron lying on a bench is opposed by the bench and held in resistance to gravity, and to move this piece of iron we have to substitute some opposing force, like that of the hands or lifting mechanism, to overcome gravity.

TWO:In a former part of this work455 we found reason to believe that Plato��s supreme good is no other than the Idea of Sameness which occurs in the Sophist and in the Timaeus, where it is correlated with the Idea of Difference; and we also concluded that the divine creator of the last-named dialogue is intended to represent it under a more concrete and popular form.456 We may, perhaps, also discover it in the Limit of the Phil��bus; and if we are to believe what Aristotle tells us about the later teaching of Plato, it seems to have finally coalesced with the Pythagorean One, which combines with the unlimited Dyad to form first number, and then everything else, just as the Same combines with the Different to form existence in the Timaeus.457"You need not be afraid," she said. "If I couldn't--ah!"

TWO:V.

TWO:Machinery of transmission being generally a part of the fixed plant of an establishment, experiments cannot be made to institute comparisons, as in the case of machines; besides, there are special or local considerations��such as noise, danger, freezing, and distance��to be taken into account, which prevent any rules of general application. Yet in every case it may be assumed that some particular plan of transmitting power is better than any other, and that plan can best be determined by studying, first, the principles of different kinds of mechanism and its adaptation to the special conditions that exist; and secondly, precedents or examples.In the workshop, mechanical knowledge of some kind is continually and often insensibly acquired by a learner, who observes the operations that are going on around him; he is continually availing himself of the experience of those more advanced, and learns by association the rules and customs of the shop, of the business, and of discipline and management. He gathers the technical terms of the fitting-shop, the forge and foundry; notes the operations of planing, turning, drilling, and boring, with the names and application of the machines directed to these operations. He sees the various plans of lifting and moving material, the arrangement and relation of the several departments to facilitate the course of the work in process; he also learns where the product of the works is sold, discusses the merits and adaptation of what is constructed, which leads to considering the wants that create a demand for this product, and the extent and nature of the market in which it is sold.
