      Pattern-makers have to thoroughly understand drawings, in order to reproduce them on the trestle boards with allowance for shrinkage, and to determine the cores; they must also understand moulding, casting, fitting, and finishing. Pattern-making as a branch of machine manufacture, should rank next to designing and drafting.A carriage moving on angular ways always moves steadily and easily, without play in any direction until lifted from its bearing, which rarely happens, and its lifting is easily opposed by adjustable gibs. A carriage on a flat shear is apt to have play in a horizontal direction because of the freedom which must exist to secure easy movement. In the case of tracks, it may also be mentioned that the weight of a carriage acts as a constant force to hold it steady, while with a flat shear the weight of a carriage is in a sense opposed to the ways, and has no useful effect in steadying or guiding. The rigidity and steadiness of tool movement is notoriously in favour of triangular tracks, so much so that nearly all American machine tool-makers construct lathes in this manner, although it adds no inconsiderable cost in fitting.

      Dick performed the mechs duties for the pilot in getting the engine started again, then he clambered into his old place. Sandy was already behind their new pilot.Some strong, pungent liquid had been poured on the green necklace, the letter from the millionaire stated. No alarm was given. My wife did not want to broadcast either the fact that she had the real gems or the trouble in the hotel. But people had heard the fire! cry and doubtless some suspected the possible truth, knowing why she was getting ready.

      Bruce shut his teeth tightly and nodded. Still, in Prout's evidence he seemed to hear the voice of his judge passing sentence.The next morning the roar of the cannon woke us up, and soon we heard how the fighting stood, for when we went to the commander for a permit to go to Dixmuiden, the sympathetic major absolutely refused it, and haltingly added that he himself did not yet know how things stood there. Well, that was enough for us. At last he gave us a permit for Ostend, and we noticed very soon that now we were in the rear of the front. Whilst the guns were thundering on continuously and the shrapnel exploded in the air, we passed continuously large contingents, who actually formed one long line. The fight was going on only a few miles away, and incessantly the unhappy wounded came out of the small bypaths, stumbling on in their heavily muddied clothes.


      "Well, there is a huge fire yonder; everything is burning!"He paused in some confusion. He had the profoundest respect for the cunning and audacity of the people with whom he had to deal. Was this some startling new plot that they had been working on him?


      Hetty turned pale. But no word of reproach passed her lips. It was no time for that. And she knew by repute the kind of creditor that Gordon had. She merely asked the name of the obdurate creditor.


      Stated briefly, Zellers theory of ancient thought is that the Greeks originally lived in harmony with Nature; that the bond was broken by philosophy and particularly by the philosophy of Socrates; that the discord imperfectly overcome by Plato and Aristotle revealed itself once more in the unreconciled, self-concentrated subjectivity of the later schools; that this hopeless estrangement, after reaching its climax in the mysticism of the Neo-Platonists, led to the complete collapse of independent speculation; and that the creation of a new consciousness by the advent of Christianity and of the Germanic races was necessary in order to the successful resumption of scientific enquiry. Zeller was formerly a Hegelian, and it seems to me that he still retains far too much of the Hegelian formalism in his historical constructions. The well-worked antithesis between object and subject, even after being revised in a positivist sense, is totally inadequate to the burden laid on it by this theory; and if we want really to understand the causes which first hampered, then arrested, and finally paralysed Greek philosophy, we must seek for them in a more concrete order of considerations. Zeller, with perfect justice, attributes the failure of Plato and Aristotle to their defective observation of Nature and their habit of regarding the logical combinations of ideas derived from the common use of words as an adequate representative of the relations obtaining among things in themselves. But it seems an extremely strained and artificial explanation to say that their shortcomings in this respect were due to a confusion of the objective and the subjective, consequent on the imperfect separation of the Greek mind from Naturea confusion, it isx added, which only the advent of a new religion and a new race could overcome.1 It is unfair to make Hellenism as a whole responsible for fallacies which might easily be paralleled in the works of modern metaphysicians; and the unfairness will become still more evident when we remember that, after enjoying the benefit of Christianity and Germanism for a thousand years, the modern world had still to take its first lessons in patience of observation, in accuracy of reasoning, and in sobriety of expression from such men as Thucydides and Hippocrates, Polybius, Archimdes and Hipparchus. Even had the Greeks as a nation been less keen to distinguish between illusion and reality than their successors up to the sixteenth centurya supposition notoriously the reverse of trueit would still have to be explained why Plato and Aristotle, with their prodigious intellects, went much further astray than their predecessors in the study of Nature. And this Zellers method does not explain at all.Meanwhile Balmayne had crept in downstairs. He crossed over and helped himself liberally to brandy. He took a second glass, and a third. But there came none of the glow of courage to his heart.
