If it were not for securing vent for gas, moulds could be made from plastic material so as to produce fine castings with clear sharp outlines.

"Oh yes, it has been destroyed already a couple of times, but we shall teach them a lesson! Why did not the Belgians allow us to pass through their country? What can their little army do against us? As soon as a sufficient number have crossed we shall go for these forts, then on to Brussels, and within a fortnight we shall be in Paris. Lige we have taken already."Tempering, as a term, is used to comprehend both hardening and drawing; as a process it depends mainly upon judgment instead of skill, and has no such connection with forging as to be performed by smiths only. Tempering requires a different fire from those employed in forging, and also more care and precision than blacksmiths can exercise, unless there are furnaces and baths especially arranged for tempering tools.
(1.) How may gauging implements affect the division of labour?(2.) In what way do standard dimensions affect the value of machinery?(3.) Why cannot cylindrical joints be fitted by trying them together?(4.) Under what circumstances is it most important that the parts of machinery should have standard dimensions?(5.) Which sense is most acute in testing accurate dimensions?(6.) How may slight variations in dimensions be made apparent to sight?Tangent wheels and spiral gearing have only what is termed line contact between the bearing surfaces, and as the action between these surfaces is a sliding one, such wheels are subject to rapid wear, and are incapable of sustaining much pressure, or transmitting a great amount of power, except the surfaces be hard and lubrication constant. In machinery the use of tangent wheels is mainly to secure a rapid change of speed, usually to diminish motion and increase force.
"Very well, sir."The material when in its crude state not only consists of various things, such as iron, sand, coal, and lumber, that must be kept separate, but the bulk of such materials is much greater than their finished product. It is therefore quite natural to receive such material on the outside or "periphery" of the works where there is the most room for entrances and for the separate storing of such supplies. Such an arrangement is of course only possible where there can be access to a considerable part of the boundary of a works, yet there are but few cases where a shop cannot be arranged in general upon the plan suggested. By receiving material on the outside, and delivering the finished product from the centre, communications between the departments of an establishment are the shortest that it is possible to have; by observing the plans of the best establishments of modern arrangement, especially those in Europe, it may be seen that this system is approximated in many of them, especially in establishments devoted to the manufacture of some special class of work.I had succeeded. I had been in Lige, the first foreign journalist who got there after her fall, and was able to contradict the numerous reports about the conquest of the forts which had made the round of the newspapers for several days.

I woke up in the morning, and when going downstairs saw that the doors of all the rooms stood open, and everything inside was in great disorder. In the caf tables and chairs were overturned, and broken looking-glasses lay on the floor. The front door was also open, and I walked away.In this grand old monastery, both inside and out a jewel of architecture, about five hundred people had found shelter. They were lodged in halls, rooms, and kitchens. The fathers gave them everything in the way of food they might require, but they had to do their own cooking. As not one of these people had a home left, which they could call their own, no wonder that they greatly admired the fathers. Often when I strolled about with one of these, one or other of the refugees came to him to press his hand and express gratitude for the hospitality offered."I have been arrested."
I did not fare better at the next. There the answer was:
