Flat or plane joints nearly always admit of adjustment between the fitted surfaces; that is, the material scraped or ground away in fitting can be compensated by bringing the pieces nearer together; but parallel cylindrical joints cannot even be tried together until finished, consequently, there can be nothing cut away in trying them together. Tapering, or conical joints, can of course be trial-fitted, and even parallel fits are sometimes made by trial, but it is evident that the only material that can [149] be cut away in such cases, is what makes the difference between a fit too close, and one which will answer in practice.
ONE:That-there is one on me! he admitted. You must have mighty quick eyes.Climb they did, until the sea dropped down to a gray-green, flat expanse and only the powerful binoculars Larry was using could pick out the cruising hydroplane slowly verging away from the shore in an apparently aimless voyage.
TWO:When they climbed above the lower shoreward mist the cry from Sandy drew their attention to the seaplane, even higher than they were, and going fast across the narrow end of the island.

ONE:It is a lamentable sign that this German, probably well educated, had not taken the slightest trouble to find out the reason for this wholesale wrecking of a town, that the whole affair impressed him so little. "Somebody" had said that those cursed civilians had been shooting, that explained it to his satisfaction, and gave him ample cause for coarse abuse of the wretched people.Where no danger could deter from the pursuit of power, no balancing of pain with pleasure availed to quench the ardour of desire. With full knowledge that violent delights have violent ends and in their triumph die, the fateful condition was accepted. Not only did Giordano Bruno, in conscious parallelism with his theory of matter, declare that without mutation, variety, and vicissitude nothing would be agreeable, nothing good, nothing delightful, that enjoyment consists solely in transition and movement, and that all pleasure lies midway between the painful longing of fresh appetite and the sadness of its satiation and extinction;558 but the sedater wisdom of Bacon, in touching on the controversy between Callicles and Socrates, seems to incline towards the side of the former; and, in all cases, warns men not to make too much of the inconveniences attendent on pleasure, but so to procure serenity as they destroy not magnanimity.559
TWO:Assuming, for example, that a machine will cost as much as the wages of an attendant for one year, which is not far from an average estimate for iron working machine tools, and that interest, wear, and repairs amount to ten per cent. on this sum, then the attendance would cost ten times as much as the machine; in other words, the wages paid to a workman to attend a machine is, on an average, ten times as much as the other expenses attending its operation, power excepted. This assumed, it follows that in machine tools any improvement directed to labour saving is worth ten times as much as an equal improvement directed to the economy of first cost.Presuming the reader to remember what was said of steam hammers in another place, and to be familiar with the uses and general construction of such hammers, let it be supposed steam-hammers, with the ordinary automatic valve action, those that give an elastic or steam-cushioned blow, are well known. Suppose further that by analysing the blows given by hammers of this kind, it is demonstrated that dead blows, such as are given when a hammer comes to a full stop in striking, are more effectual in certain kinds of work, and that steam-hammers would be improved by operating on this dead-stroke principle.

TWO:Workshop processes which are capable of being systematised are the most easy to learn. When a process is reduced to a system it is no longer a subject of special knowledge, but comes within general rules and principles, which enable a learner to use his reasoning powers to a greater extent in mastering it."These banknotes were paid to your firm?" he asked.
FORE:"There!" she cried. "And now to keep your part of the compact. If you have got round Maitrank you are a genius. Where are the men?"This mode of reasoning will lead to proper estimates of the difference in value between good tools and inferior tools; the results of performance instead of the investment being first considered, because the expenses of operating are, as before assumed, usually ten times as great as the interest on the value of a machine.
FORE:"Goodnight, comrades," said Lalage. "I shall return presently. Come on, dog, follow at the heels of your master."
FORE:My obligations to other writers have been acknowledged throughout this work, so far as I was conscious of them, and so far as they could be defined by reference to specific points. I take the present opportunity for mentioning in a more general way the valuable assistance which I have derived from Schweglers Geschichte der Griechischen Philosophie, Langes Geschichte des Materialismus, and Dührings Geschichte der Philosophie. The parallel between Socrates, Giordano Bruno, and Spinoza was probably suggested to mexxiv by Dühring, as also were some points in my characterisation of Aristotle. As my view of the position occupied by Lucretius with respect to religion and philosophy differs in many important points from that of Prof. Sellar, it is the more incumbent on me to state that, but for a perusal of Prof. Sellars eloquent and sympathetic chapters on the great Epicurean poet, my own estimate of his genius would certainly not have been written in its present form and would probably not have been written at all.
FORE:Charlton rose; the woman's coolness and nerve were inflammable to him.
FORE:Jeff chews gum, he mused. He pretended not to know any was in this amphibian. But its gone! Well, he told himself, Ill watch and see what hes up to. Hell give himself away yet!This place is empty, too, Dick agreed. Where could?
FORE:Starting again from the cutting point, and going the other way from the tool to the frame, there is, first, a clamped and stayed joint between the material and platen, next, a running joint between the platen and frame; this is all; one joint that is firm beyond any chance of movement, and a moving joint that is not held by adjustable gibs, but by gravity; a force which acts equally at all times, and is the most reliable means of maintaining a steady contact between moving parts.
TWO:The name of having been an apprentice to a famous firm may sometimes have an influence in enabling an engineer to form advantageous commercial connections, but generally an apprenticeship is of value only as it has furnished substantial knowledge and skill; for every one must sooner or later come down to the solid basis of their actual abilities and acquirements. The engineering interest is by far too practical to recognise a shadow instead of true substance, and there is but little chance of deception in a calling which deals mainly with facts, figures, and positive demonstration.
TWO:There it appeared that my papers were in good order, but at the same time I was informed that I was to be taken to the commanding officer at the station and could not be allowed to leave Bilsen for the present. I was escorted through the townlet, which appeared to be entirely deserted; but now and then somebody came to his front-door to watch the latest victim of the Germans being led past. At the station I was pushed without much courtesy into a keep where six other civilians sat, who had been picked up as being at large, and whose faces were now covered with a cold perspiration from fear, because they were firmly convinced that by and by they would be shot.For other kinds of work there are drawings furnished, and the plans are dictated by the engineering department of machinery-building establishments, but pattern-makers make their own plans for constructing their work, and have even to reproduce the drawings of the fitting-shop to work from. Nearly everything pertaining to patterns is left to be decided by the pattern-maker, who, from the same drawings, and through the exercise of his judgment alone, may make patterns that are durable and expensive, or temporary and cheap, as the probable extent of their use may determine.

"Some mistake," said Bruce. "I certainly paid forty five-pound notes here the day after the murder, but they came into my possession the night before. If those are the notes you say they are I never touched them."Leona Lalage said nothing. She could only look and look in a fascinated way.I had to repeat everything about the advance of the French and the landing of the British, whilst they followed my story on the map. But I was soon in a cold sweat, for of course I knew practically nothing, neither of the French nor of the British, and each time when one of the officers pressed for details I was in mortal fear that I might contradict myself. But I stuck to my guns until the end, and assured them that the French had crossed the Belgian frontier near Givet, and were now near Namur, whereas the British, disembarking at Ostend, had advanced as far as Ghent.
