The similarity of the operations carried on in all works directed to the manufacture of machinery, and the kind of knowledge that is required in planning and conducting such works, would lead us to suppose that at least as much system would exist in machine shops as in other manufacturing establishments, which is certainly not the case. There is, however, this difference to be considered: that whereas many kinds of establishments can be arranged at the beginning for a specific amount of business, machine shops generally grow up around a nucleus, and are gradually extended as their reputation and the demands for their productions increase; besides, the variety of operations required in an engineering establishment, and change from one class of work to another, are apt to lead to a confusion in arrangement, which is too often promoted, or at least not prevented, by insufficient estimates of the cost of handling and moving material.1. That the drop and valve, while they must act relatively, cannot move in the same time, or in direct unison.The war is not over yet, and much is still hidden under a veil, but after the war it will undoubtedly be the duty of the Louvain people to twine a magnificent wreath round the three names Noyons-Nerincx-Claes.

"Sister," I said, "I am a cousin of S?ur Eulalie, and should like to see her, to know how she is and take her greetings to her family in The Netherlands."In every case where there can be a question as to whether gearing shafts or belts will be the best means of transmitting power, the several conditions named will furnish a solution if they are properly investigated and understood. Speed, noise, or angles may become determinative conditions, and are such in a large number of cases; first cost and loss of power are generally secondary conditions. Applying these tests to cases where belts, shafts, or wheels may be employed, a learner will soon find himself in possession of knowledge to guide him in his own schemes, and enable him to judge of the correctness of examples that come under his notice.I pulled them out: birth certificate, certificate of good conduct, foreign passport, and press-card, which were examined the one after the other.

After the explanations required of us they allowed us to go on. The incessant roar of the guns made the girl tremble for fear, and the stinging smoke made her cough. After much trouble we got at last as far as Herstal, where I had promised her a short rest.��

�If a drawing is to be elaborate, or to remain long upon a board, the paper should be pasted down. To do this, first prepare thick mucilage, or what is better, glue, and have it ready at hand, with some slips of absorbent paper an inch or so wide. Dampen the sheet on both sides with a sponge, and then apply the mucilage along the edge, for a width of one-fourth or three-eighths of an inch. It is a matter of some difficulty to place a sheet upon a board; but if the board is set on its edge, the paper can be applied without assistance. Then, by placing the strips of paper along the edge, and rubbing over them with some smooth hard instrument, the edges of the sheet can be pasted firmly to the board, the paper slips taking up a part of the moisture from the edges, which are longest in drying. If left in this condition, the centre will dry first, and the paper be pulled loose at the edges by contraction before the paste has time to dry. It is therefore necessary to pass over the centre of the sheet with a wet sponge at intervals to keep the paper slightly damp until the edges adhere firmly, when it can be left to dry, and will be tight and smooth. In this operation much will be learned by practice, and a beginner should not be discouraged by a few failures. One of the most common difficulties in mounting sheets is in not having the gum or glue thick enough; when thin, it will be absorbed by the wood or the paper, or is too long in drying; it should be as thick as it can be applied with a brush, and made from clean Arabic gum, tragacanth, or fine glue.A GLORIOUS summer evening, quite refreshing after the exhausting heat of the day. Nature invited to restfulness, and so much the more cruel sounded the incessant thunder of the guns, which also boomed from the citadel. As soon as the Germans had taken possession of this old, dilapidated fortress they proceeded to drag their guns on to it, and trained them on the surrounding forts.

"Are they genuine?""But really, madame, that is only senseless gossip of the people. You need not be afraid, the Germans will not be so cruel as all that!"

(1.) Why are machine frames constructed in sections, instead of being in one piece?—(2.) Why must parts which have contact on opposite sides have specific dimensions?—(3.) What are standards of measure based upon in England, America, and France?—(4.) How can weight be measured by time?—(5.) Has the French metre proved a standard admitting of test reference?Standard gauging implements were introduced about the year 1840, by the celebrated Swiss engineer, John G. Bodmer, a [148]man who for many reasons deserves to be considered as the founder of machine tool manufacture. He not only employed gauges in his works to secure duplicate dimensions, but also invented and put in use many other reforms in manipulation; among these may be mentioned the decimal or metrical division of measures, a system of detail drawings classified by symbols, the mode of calculating wheels by diametric pitch, with many other things which characterise the best modern practice.�

That mad fury was also intensified considerably by the accusations about gruesome mutilations committed on German soldiers by Belgians, who were said to have cut off the noses, ears, genitals, and so on of their enemies. These rumours were so persistent that in the end it was generally believed in neutral countries that these things had happened frequently.It is not always an easy matter to hit upon an object to which designs may be directed; and although at first thought it may seem that any machine, or part of a machine, is capable of improvement, it will be found no easy matter to detect existing [153] faults or to conceive plans for their remedy.One of the effects of employing gauges in machine fitting is to inspire confidence in workmen. Instead of a fit being regarded as a mysterious result more the work of chance than design, men accustomed to gauges come to regard precision as something both attainable and indispensable. A learner, after examining a set of well fitted cylindrical gauges, will form a new conception of what a fit is, and will afterwards have a new standard fixed in his mind.

I THINK that there is no better occasion to deal with the question whether there was a franc-tireur-guerilla in Belgium than after the chapter on the destruction of Visé.��
