FORE:Quickly he lowered the rope till the bulge of it showed that the bottom was reached. He wound up the rope again, and as he did so a grunt of satisfaction escaped him. It was far better than he had expected.Balmayne groveled helplessly. There were tears in his eyes. The man could plot and intrigue, he could make the weapons for others, but he had no heart for them himself. He was an abject coward without feeling for anyone but himself. He would have left his nearest to starve or die without a prick of conscience, but he was nervous for himself. And he read his sentence in Lalage's eyes.
FORE:CHAPTER XXII. FOR LOVE AND DUTY.We are told that when his end began to approach, the dying philosopher was pressed to choose a successor in the headship of the School. The manner in which he did this is289 characteristic of his singular gentleness and unwillingness to give offence. It was understood that the choice must lie between his two most distinguished pupils, Theophrastus of Lesbos, and Eudmus of Rhodes. Aristotle asked for specimens of the wine grown in those islands. He first essayed the Rhodian vintage, and praised it highly, but remarked after tasting the other, The Lesbian is sweeter, thus revealing his preference for Theophrastus, who accordingly reigned over the Lyceum in his stead.179
FORE:With which cynical remark Lawrence lighted a cigarette and departed. From above the fretful voice of Mamie called to her dear Hetty. In sooth, the child was running a great risk of being spoilt.Coming back, dropped low, Jeff scanned the beach.
FORE: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.Leona Lalage was off the sofa directly. She motioned to the door. As Hetty came back the sufferer crossed the room languidly, saying she was going to lie down on her bed. She required no attention, she only wanted to be absolutely quiet.
FORE:Milling relates to metal cutting with serrated rotary cutters, and differs in many respects from either planing or turning. The movement of the cutting edges can be more rapid than with tools which act continuously, because the edges are cooled during the intervals between each cut; that is, if a milling tool has twenty teeth, any single tooth or edge acts only from a fifteenth to a twentieth part of the time; and as the cutting distance or time of cutting is rarely long enough to generate much heat, the speed of such tools may be one-half greater than for turning, drilling, or planing tools. Another distinction between milling and other tools is the perfect and rigid manner in which the cutting edges are supported; they are short and blunt, besides being usually carried on short rigid mandrils. A result of this rigid support of the tools is seen in the length of the cutting edges that can be employed, which are sometimes four inches or more in length. It is true the amount of material cut away in milling is much less than the edge movement will indicate when compared with turning or planing; yet the displacing capacity of a milling machine exceeds that of either a lathe or a planing machine. Theoretically the cutting or displacing capacity of any metal or wood cutting machine, is as the length of the edges multiplied into the speed of their cutting movement; a rule which applies very uniformly in wood cutting, and also in metal cutting within certain limits; but the strains that arise in metal cutting are so great that they may exceed all means of resisting them either in the material acted upon, or in the means of supporting tools, so that the length of cutting edges is limited. In turning chilled rolls at Pittsburg, [141] tools to six inches wide are employed, and the effect produced is as the length of the edge; but the depth of the cut is slight, and the operation is only possible because of the extreme rigidity of the pieces turned, and the tools being supported without movable joints as in common lathes.
