ENGLISH As remarked in the case of other machines treated of, there is no use of describing the mechanism of trip-hammers; it is presumed that every engineer apprentice has seen trip-hammers, or can do so; and the plan here is to deal especially with what he cannot see, and would not be likely to learn by casual observation."So this brave lady succeeded in getting the sentence of death withdrawn. But the Germans wanted to torture their wretched prisoners on any or no plea. They were placed near the church wall, kept standing there all night, were told that they would be shot by and by, and threatened by the soldiers with their bayonets.

It is important, in asking questions, to consider the mood and present occupation of the person addressed; one question asked when a man's mind is not too much occupied, and when he is in a communicative humour, is worth a dozen questions asked when he is engaged, and not disposed to talk.

Rapping plates, draw-irons, and other details of pattern-making are soon understood by observation. Perhaps the most useful suggestion which can be given in reference to draw-irons is to say they should be set on the under or bottom side of patterns, instead of on the top, where they are generally placed. A draw-plate set in this way, with a hole bored through the pattern so as to insert draw-irons from the top, cannot pull off, which it is apt to do if set on the top side. Every pattern no matter how small, should be ironed, unless it is some trifling piece, with dowel-pins, draw and rapping plates. If a system of draw-irons is not rigidly carried out, moulders will not trouble themselves to take care of patterns."Yes, all right, you may go, but we only want you to tell us what you know of this man."CHAPTER XX. GENERALISATION OF SHOP PROCESSES.

2. The necessity for, and consequent saving effected by, power-machinery for handling is mainly in vertical lifting, horizontal movement being easily performed by hand."9. Van Hoeyaerden, member of the Town Council.

Although I had been commanded to return "at once" to Maastricht, I succeeded in having a chat here and there with the inhabitants of Riemst. I had visited the village about eight days ago, but what a change! Then the people assured me that "die Duutschen"[2] were not so bad after all, that they were compelled to do their duty, and were kind to the inhabitants if these were kind to them.

It is easy to learn "how" to draw, but it is far from easy to learn "what" to draw. Let this be kept in mind, not in the way of [79] disparaging effort in learning "how" to draw, for this must come first, but in order that the objects and true nature of the work will be understood.

Leaving out the matter of a positive relative movement between shafts, which belts as a means of transmitting power cannot insure, there are the following conditions that must be considered in determining whether belts or other means should be employed in transmitting power from one machine to another or between the parts of machines.Trip-hammers employed in forging bear a close analogy to, and were no doubt first suggested by, hand-hammers. Being the oldest of power-forging machines, and extensively employed, it will be proper to notice trip-hammers before steam-hammers.

I shuddered at the thought that in these days such barbarities were possible. I asked the soldiers whether I was allowed to enter the burning village, but the commanding sergeant refused his consent.There is nothing in the construction or operation of milling machines but what will be at once understood by a learner who sees them in operation. The whole intricacy of the process lies in its application or economic value, and but very few, even among the most skilled, are able in all cases to decide when milling can be employed to advantage. Theoretical conclusions, aside from practical experience, will lead one to suppose that milling can be applied in nearly all kinds of work, an opinion [143] which has in many cases led to serious mistakes.2. The speed at which the transmitting machinery must move.
