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.

It has been the fashion in certain quarters to look down on these early thinkersto depreciate the value of their speculations because they were thinkers, because, as we have already noticed, they reached their most important conclusions by thinking, the means of truly scientific observation not being within their reach. Nevertheless, they performed services to humanity comparable for value with the legislation of Solon and Cleisthenes, or the victories of Marathon and Salamis; while their creative imagination was not inferior to that of the great lyric and dramatic poets, the great architects and sculptors, whose contemporaries they were. They first taught men to distinguish between the realities of nature and the illusions of sense; they discovered or divined the indestructibility of matter and its atomic constitution; they taught that space is infinite, a conception so far from being self-evident that it transcended the capacity of Aristotle to grasp; they held that the seemingly eternal universe was brought into its present form by the operation of mechanical forces which will also effect its dissolution; confronted by the seeming permanence and solidity of our planet, with the innumerable varieties of life to be found on its surface, they declared that all things had arisen by differentiation8 from a homogeneous attenuated vapour; while one of them went so far as to surmise that man is descended from an aquatic animal. But higher still than these fragmentary glimpses and anticipations of a theory which still awaits confirmation from experience, we must place their central doctrine, that the universe is a cosmos, an ordered whole governed by number and law, not a blind conflict of semi-conscious agents, or a theatre for the arbitrary interference of partial, jealous,6 and vindictive gods; that its changes are determined, if at all, by an immanent unchanging reason; and that those celestial luminaries which had drawn to themselves in every age the unquestioning worship of all mankind were, in truth, nothing more than fiery masses of inanimate matter. Thus, even if the early Greek thinkers were not scientific, they first made science possible by substituting for a theory of the universe which is its direct negation, one that methodised observation has increasingly tended to confirm. The garland of poetic praise woven by Lucretius for his adored master should have been dedicated to them, and to them alone. His noble enthusiasm was really inspired by their lessons, not by the wearisome trifling of a moralist who knew little and cared less about those studies in which the whole soul of his Roman disciple was absorbed.For reply Larry strode over to the metal door set in the wall for use when anyone chose to enter or leave the hangar.Sweet tones are remembered not.

FORE:"What?"The poor wretches, who expected to be killed at any moment, were driven into squares or the meadows, where they were exposed to the chilly night air, so that several babies perished. Only the next morning were the women and children allowed to leavethat is to say, they were told to take the shortest way to Maastricht.

FORE:It would be inferred that the arrangement of these double acting hammers must necessarily be complicated and expensive, but the contrary is the fact. The rams are simply two masses of iron mounted on wheels that run on ways, like a truck, and the impact of the hammers, so far as not absorbed in the work, is [114] neutralised by each other. No shock or jar is communicated to framing or foundations as in the case of single acting hammers that have fixed anvils. The same rule applies in the back stroke of the hammers as the links which move them are connected together at the centre, where the power is applied at right angles to the line of the hammer movement. The links connecting the two hammers constitute, in effect, a toggle joint, the steam piston being attached where they meet in the centre.

FORE:Fifth.Shrinkage; the allowance that has to be made for the contraction of castings in cooling, in other words, the difference between the size of a pattern and the size of the casting. This is a simple matter apparently, which may be provided for in allowing a certain amount of shrinkage in all directions, but when the inequalities of shrinkage both as to time and degree are taken into account, the allowance to be made becomes a problem of no little complication.

ONE:The man behind staggered back and muttered something that sounded like admiration. Ren Lalage stepped inside and shut the door.
TWO:Socrates was, before all things, an Athenian. To under126stand him we must first understand what the Athenian character was in itself and independently of disturbing circumstances. Our estimate of that character is too apt to be biassed by the totally exceptional position which Athens occupied during the fifth century B.C. The possession of empire developed qualities in her children which they had not exhibited at an earlier period, and which they ceased to exhibit when empire had been lost. Among these must be reckoned military genius, an adventurous and romantic spirit, and a high capacity for poetical and artistic productionqualities displayed, it is true, by every Greek race, but by some for a longer and by others for a shorter period. Now, the tradition of greatness does not seem to have gone very far back with Athens. Her legendary history, what we have of it, is singularly unexciting. The same rather monotonous though edifying story of shelter accorded to persecuted fugitives, of successful resistance to foreign invasions, and of devoted self-sacrifice to the State, meets us again and again. The Attic drama itself shows how much more stirring was the legendary lore of other tribes. One need only look at the few remaining pieces which treat of patriotic subjects to appreciate the difference; and an English reader may easily convince himself of it by comparing Mr. Swinburnes Erechtheus with the same authors Atalanta. There is a want of vivid individuality perceptible all through. Even Theseus, the great national hero, strikes one as a rather tame sort of personage compared with Perseus, Heracls, and Jason. No Athenian figures prominently in the Iliad; and on the only two occasions when Pindar was employed to commemorate an Athenian victory at the Panhellenic games, he seems unable to associate it with any legendary glories in the past. The circumstances which for a long time made Attic history so barren of incident are the same to which its subsequent importance is due. The relation in which Attica stood to the rest of Greece was somewhat similar to the relation in127 which Tuscany, long afterwards, stood to the rest of Italy. It was the region least disturbed by foreign immigration, and therefore became the seat of a slower but steadier mental development. It was among those to whom war, revolution, colonisation, and commerce brought the most many-sided experience that intellectual activity was most speedily ripened. Literature, art, and science were cultivated with extraordinary success by the Greek cities of Asia Minor, and even in some parts of the old country, before Athens had a single man of genius, except Solon, to boast of. But along with the enjoyment of undisturbed tranquillity, habits of self-government, orderliness, and reasonable reflection were establishing themselves, which finally enabled her to inherit all that her predecessors in the race had accomplished, and to add, what alone they still wanted, the crowning consecration of self-conscious mind. There had, simultaneously, been growing up an intensely patriotic sentiment, due, in part, to the long-continued independence of Attica; in part, also, we may suppose, to the union, at a very early period, of her different townships into a single city. The same causes had, however, also favoured a certain love of comfort, a jovial pleasure-seeking disposition often degenerating into coarse sensuality, a thriftiness, and an inclination to grasp at any source of profit, coupled with extreme credulity where hopes of profit were excited, together forming an element of prose-comedy which mingles strangely with the tragic grandeur of Athens in her imperial age, and emerges into greater prominence after her fall, until it becomes the predominant characteristic of her later days. It is, we may observe, the contrast between these two aspects of Athenian life which gives the plays of Aristophanes their unparalleled comic effect, and it is their very awkward conjunction which makes Euripides so unequal and disappointing a poet. We find, then, that the original Athenian character is marked by reasonable reflection, by patriotism, and by a tendency towards self-seeking128 materialism. Let us take note of these three qualities, for we shall meet with them again in the philosophy of Socrates.

ONE:Later on I heard the same story from several other inhabitants."Because there was one who hated him. I cannot and will not say any more than that. He stood in the way of somebody. So long as he kept away it was all right. But Leon was not one of that sort. He was as brave as a lion. Had he not been so fond of the drink he might have done anything. But there was something in the blood of both of us that took us into evil ways. Thank God our mother is dead, the flower farm gone, and the secret of the wonderful perfume that made the name of Lalage famous for two centuries is buried in my mother's grave."

FORE:In fixing the relation of Plotinus to his own age, we have gone far towards fixing his relation to all ages, the place which350 he occupies in the development of philosophy as a connected whole. We have seen that as an attempt to discover the truth of things, his speculations are worthless and worse than worthless, since their method no less than their teaching is false. Nevertheless, Wisdom is justified of all her children. Without adding anything to the sum of positive knowledge, Plotinus produced an effect on mens thoughts not unworthy of the great intellect and pure life which he devoted to the service of philosophy. No other thinker has ever accomplished a revolution so immediate, so comprehensive, and of such prolonged duration. He was the creator of Neo-Platonism, and Neo-Platonism simply annihilated every school of philosophy to which it was opposed. For thirteen centuries or more, the three great systems which had so long divided the suffrages of educated mindsStoicism, Epicureanism, and Scepticismceased to exist, and were allowed to lapse into such complete oblivion that only a few fragments of the works in which they were originally embodied have been preserved. And Plotinus was enabled to do this by the profound insight which led him to strike less at any particular doctrine held by his opponents than at the common foundation on which they all stood, the materialism openly professed by the Stoics and Epicureans, and assumed by the Sceptics as the necessary presupposition of every dogmatic philosophy. It is true that the principle which he opposed to theirs was not of his own origination, although he stated it more powerfully than it had ever been stated before. But to have revived the spiritualism of Plato and Aristotle in such a way as to win for it universal acceptance, was precisely his greatest merit. It is also the only one that he would have claimed for himself. As we have already mentioned, he professed to be nothing more than the disciple of Plato. And although Aristotelian ideas abound in his writings, still not only are they overbalanced by the Platonic element, but Plotinus might justly have contended that they also belong, in a sense, to Plato,351 having been originally acquired by a simple development from his teaching.An apprentice must guard against the too common impression that the engine, cylinder, piston, valves, and so on, are the main parts of steam machinery, and that the boiler and furnace are only auxiliaries. The boiler is, in fact, the base of the whole, that part where the power is generated, the engine being merely an agent for transmitting power from the boiler to work that is performed. This proposition would, of course, be reached by any one in reasoning about the matter and following it to a conclusion, but the fact should be fixed in the mind at the beginning.

THREE:The principal improvements and changes in machine fitting at the present time is in the application of special tools. A lathe, a planing machine, or drilling machine as a standard machine, must be adapted to a certain range of work, but it is evident that if such tools were specially arranged for either the largest or the smallest pieces that come within their capacity, more work could be performed in a given time and consequently at less expense. It is also evident that machine tools must be kept constantly at work in order to be profitable, and when there are not sufficient pieces of one kind to occupy a machine, it must be employed on various kinds of work; but whenever there are sufficient pieces of the same size upon which certain processes of a uniform character are to be performed, there is a gain by having machines constructed to conform as nearly as possible to the requirements of special work, and without reference to any other.Prout rose and bowed to Hetty.

"No, I am not," came the slow reply. "Oh, you are a clever man, without doubt, and you have the air of one who holds all the cards. It will be a pleasure for me to listen to what you have to say."WITH THE FLEMINGSIn casting and forging operations the material is treated while in a heated and expanded condition; the nature of these operations is such that accurate dimensions cannot be attained, so that both forgings and castings require to be made enough larger than their finished dimensions to allow for shrinkage and irregularities. Finishing as a process consists in cutting away this surplus material, and giving accurate dimensions to the parts of machinery when the material is at its natural temperature. Finishing operations being performed as said upon material at its normal temperature permits handling, gauging and fitting together of the parts of machinery, and as nearly all other processes involve heating, finishing may be called the cold processes of metal work. The operations of a fitting shop consist almost entirely of cutting, and grinding or abrading; a proposition that may seem novel, yet these operations comprehend nearly all that is performed in what is called fitting.
