FORE:But it was only Mamie whimpering and crying for her. The child was awake and sitting up in bed, whilst the nurse still slept. Mamie was hot and feverish.In studying improvements with a view to practical gain, a learner can have no reasonable hope of accomplishing much in fields already gone over by able engineers, nor in demonstrating anything new in what may be called exhausted subjects, such as steam-engines or water-wheels; he should rather choose new and special subjects, but avoid schemes not in some degree confirmed by existing practice.

FORE:"Quick," she whispered. "Quick. Has the blow fallen?"

FORE:"Is that so? I beg your pardon, but won't you come with me? I suppose that you want a passport. I will take you to the commander."

FORE:Plato was born in the year 429, or according to some accounts 427, and died 347 B.C. Few incidents in his biography can be fixed with any certainty; but for our purpose the most general facts are also the most interesting, and about these we have tolerably trustworthy information. His family was one of the noblest in Athens, being connected on the father��s side with Codrus, and on the mother��s with Solon; while two of his kinsmen, Critias and Charmides, were among the chiefs of the oligarchic party. It is uncertain whether he inherited any considerable property, nor is the question one of much importance. It seems clear that he enjoyed the best education Athens could afford, and that through life he possessed a competence sufficient to relieve him from the cares of material existence. Possibly the preference which he expressed, when far advanced in life, for moderate health and190 wealth arose from having experienced those advantages himself. If the busts which bear his name are to be trusted, he was remarkably beautiful, and, like some other philosophers, very careful of his personal appearance. Perhaps some reminiscences of the admiration bestowed on himself may be mingled with those pictures of youthful loveliness and of its exciting effect on the imaginations of older men which give such grace and animation to his earliest dialogues. We know not whether as lover or beloved he passed unscathed through the storms of passion which he has so powerfully described, nor whether his apparently intimate acquaintance with them is due to divination or to regretful experience. We may pass by in silence whatever is related on this subject, with the certainty that, whether true or not, scandalous stories could not fail to be circulated about him.

FORE:In planing and turning, the tools require no exact form; they can be roughly made, except the edge, and even this, in most cases, is shaped by the eye. Such tools are maintained at a trifling expense, and the destruction of an edge is a matter of no consequence. The form, temper, and strength can be continually adapted to the varying conditions of the work and the hardness of material. The line of division between planing and milling is fixed by two circumstances��the hardness and uniformity of the material to be cut, and the importance of duplication. Brass, clean iron, soft steel, or any homogeneous metal not hard enough to cause risk to the tools, can be milled at less expense than planed, provided there is enough work of a uniform character to justify the expense of milling tools. Cutting the teeth of wheels is an example where milling is profitable, but not to the extent generally supposed. In the manufacture of small arms, sewing machines, clocks, and especially watches, where there is a constant and exact duplication of parts, milling is indispensable. Such manufactures are in some cases founded on milling operations, as will be pointed out in another chapter.

FORE:I think that my answer left nothing to be desired for plainness, and Germany cannot have derived much pleasure from its official contradiction. Moreover, the editor of De Tijd had also made inquiries from the little girl whom I escorted from Louvain on the day of the occurrence at Landen, and although I admit at once that not too great a value can be attached to the evidence of a girl of nine, I insert here what the editor wrote about that interview:��

FORE:The importance of standard dimensions, and the effect which a system of gauging may have in the construction of machines, will be a matter of some difficulty for a learner to understand. The interchangeability of parts, which is the immediate object in employing gauges, is plain enough, and some of the advantages at once apparent, yet the ultimate effects of such a system extend much farther than will at first be supposed.
