      Yes, I did all thatand I guess I will explain. I meant to, anyhowor I wouldnt have brought you here.Another principle in planing machines which deserves notice is the manner of driving carriages or platens; this is usually performed by means of spur wheels and a rack. A rack movement is smooth enough, and effective enough so far as a mechanical connection between the driving gearing and a platen, but there is a difficulty met with from the torsion and elasticity of cross-shafts and a train of reducing gearing. In all other machines for metal cutting, it has been a studied object to have the supports for both the tools and the material as rigid as possible; but in the common type of planing machines, such as have rack and pinion movement, there is a controversion of this principle, inasmuch as a train of wheels and several cross-shafts constitute a very effective spring between the driving power and the point of cutting, a matter that is easily proved by planing across the teeth of a rack, or the threads of a screw, on a machine arranged with spur wheels and the ordinary reducing gearing. It is true the inertia of a platen is interposed and in a measure overcomes this elasticity, but in no degree that amounts to a remedy.


      We entered another caf, and once more I shouted51 for the inhabitants at the top of my voice. At last I heard a feeble sound somewhere in the hall, which I entered, but as I saw no one there, I called out once more. Then I heard distinctly, and knew whence the answer came. I opened a door, behind which stairs led to the cellar, and from there I was at last able to speak to some of the Herstal people. I heard that all of them stayed in their cellars for fear of the bombardment.

      The gamblers looked at one another uneasily, but not one word was said."Do you propose to go any further today?" the coroner asked.


      Mamie declined fretfully. "She wanted water, and that on the table was quite warm." With a patient smile Hetty went downstairs to get more. Mamie drank thirstily. Hetty picked up the little bottle to pour out the drops.

      CHAPTER L. THREATENED RUIN."Nemesis is slow but sure," he said. "My turn will come. That letter is locked up in the safe yonder. Would you like to see it and compare it with my own ordinary handwriting? Oh, that was a wonderful woman!"

      The cost of production is an element that continually modifies or improves manufacturing processes, determines the success of every establishment, and must be considered continually in making drawings, patterns, forgings, and castings. Machines are constructed because of the difference between what they cost and what they sell forbetween their manufacturing cost and market value when they are completed.CHAPTER IV MYSTERY OVER THE OCEAN

      It was from mathematical science that the light of certainty first broke. Socrates had not encouraged the study of mathematics, either pure or applied; nor, if we may judge from some disparaging allusions to Hippias and his lectures in the Protagoras, did Plato at first regard it with any particular favour. He may have acquired some notions of arithmetic and geometry at school; but the intimate acquaintance with, and deep interest in them, manifested throughout his later works, probably dates from his visits to Italy, Sicily, Cyrn, and Egypt. In each of these places the exact sciences were cultivated with more assiduity than at Athens; in southern Italy they had been brought into close connexion with philosophy by a system of mystical interpretation. The glory of discovering their true speculative significance was reserved for Plato. Just as he had detected a profound analogy between the Socratic scepticism and the Heracleitean flux, so also, by another vivid intuition, he saw in the definitions and demonstrations of geometry a type of true reasoning, a particular application of the Socratic logic. Thus the two studies were brought into fruitful reaction, the one gaining a wider applicability, and the other an exacter method of proof. The mathematical spirit ultimately proved211 too strong for Plato, and petrified his philosophy into a lifeless formalism; but no extraneous influence helped so much to bring about the complete maturity of his constructive powers, in no direction has he more profoundly influenced the thought of later ages.CHAPTER LII.

      They drank deep, in long draughts, with trembling lips, and beseeched us not to leave them again: "Oh, gentlemen, then we shall die!" We swore that we should come back, and that later on carriages would arrive from Louvain to take them to some convent or hospital; and, trusting us, they resigned themselves in the end.130
