At Jupile I saw a pontoon-bridge, not in use for38 the moment. Just before this place a slightly sloping road leads from the hills to the eastern bank of the Meuse and the main road Vis-Lige. Along this road descended at that moment an immense military forceuhlans, cuirassiers, infantry, more cuirassiers, artillery, munition and forage-carts. The train seemed endless, and although I stood there looking at it for quite a long time, the end had not passed me.An interesting example in the use of belts for communicating power to movable machinery is furnished by the travelling cranes of Mr Ramsbottom, in the shops of the L. & N. W. Railway, at Crewe, England, where powerful travelling cranes receive both the lifting and traversing power by means of a cotton rope not more than three-fourths of an inch in diameter, which moves at a high velocity, the motion being reduced by means of tangent wheels and gearing to attain the force required in lifting heavy loads. Observing the operation of this machinery, a person not familiar with the relations between force and motion will be astonished at the effect produced by the small rope which communicates power to the machinery."The orders issued by Monsieur Collins remain valid.
Draughting, or drawing, as it is more commonly called, is a means by which mental conceptions are conveyed from one person to another; it is the language of mechanics, and takes the place of words, which are insufficient to convey mechanical ideas in an intelligible manner.On that evening the soldiers, rough fellows from East Prussia, had been revelling in the cafs, shouting filthy ditties in the streets, and most of them in a very advanced state of intoxication. At ten o'clock suddenly a shot was heard. The fellows took their rifles, which they had placed against the walls, or on the tables of the cafs, and ran into the street shouting in a mad rage: "They have been shooting!" The most tipsy began to shoot at doors and windows simultaneously in various parts of the town, which made the people in the houses scream, and this excited the mad drunken soldiers all the more.73 They forced their way into several houses, knocking down the frightened inhabitants when these tried to stop them.

A drilling machine, adapted to the usual requirements of a machine fitting establishment, consists essentially of a spindle arranged to be driven at various speeds, with a movement for feeding the drills; a firm table set at right angles to the spindle, and arranged with a vertical adjustment to or from the spindle, and a compound adjustment in a horizontal plane. The simplicity of the mechanism required to operate drilling tools is such that it has permitted various modifications, such as column drills, radial drills, suspended drills, horizontal drills, bracket drills, multiple drills, and others.Another principle in planing machines which deserves notice is the manner of driving carriages or platens; this is usually performed by means of spur wheels and a rack. A rack movement is smooth enough, and effective enough so far as a mechanical connection between the driving gearing and a platen, but there is a difficulty met with from the torsion and elasticity of cross-shafts and a train of reducing gearing. In all other machines for metal cutting, it has been a studied object to have the supports for both the tools and the material as rigid as possible; but in the common type of planing machines, such as have rack and pinion movement, there is a controversion of this principle, inasmuch as a train of wheels and several cross-shafts constitute a very effective spring between the driving power and the point of cutting, a matter that is easily proved by planing across the teeth of a rack, or the threads of a screw, on a machine arranged with spur wheels and the ordinary reducing gearing. It is true the inertia of a platen is interposed and in a measure overcomes this elasticity, but in no degree that amounts to a remedy."Oh no, sir, not at all!"
It may be assumed that the same conditions apply to the standards of a common planing machine, but the case is different; the upright framing is easily made strong enough by increasing its depth; but the strain upon running joints is as the distance from them at which a force is applied, or to employ a technical phrase, as the amount of overhang. With a moving platen the larger and heavier a piece to be planed, the more  firmly a platen is held down; and as the cross section of pieces usually increases with their depth, the result is that a planing machine properly constructed will act nearly as well on thick as thin pieces.But here he looked at me in a curious manner, scrutinising my face, as if he asked himself: "Is he pulling my leg, or not?" But not a muscle in my face moved, so that the "Captain" nodded approvingly ... and wrote out a pass for me to go to Vis! I was not allowed to go to Lige, for, as he said, he did not yet know himself how matters stood there. The other officers overwhelmed me with questions: how matters stood in The Netherlands, and whether Great Britain had already27 declared war against us? I think that at that question I looked utterly perplexed, for in the same breath they told me all they knew about the danger of war for The Netherlands: Great Britain first sent an ultimatum to The Netherlands, to force her into joining the Allies against Germany, and as she had refused, the British Fleet was now on its way to Flushing. I explained to them in detail that they were utterly wrong, but they believed only a half of what I said.
Starting again from the cutting point, and going the other way from the tool to the frame, there is, first, a clamped and stayed joint between the material and platen, next, a running joint between the platen and frame; this is all; one joint that is firm beyond any chance of movement, and a moving joint that is not held by adjustable gibs, but by gravity; a force which acts equally at all times, and is the most reliable means of maintaining a steady contact between moving parts."The powerful German army, victorious in our district, has promised to respect our land and private possessions.
"Is this then the road to Vis?"I saw some extremely poor people, very old and stiff, to whom walking was nearly impossible. A Bavarian soldier escorted them. He had his rifle slung across his back and in both hands carried the luggage of the unfortunate creatures. He seemed to have come a long way already, for he looked tired, and the perspiration ran down his face. Although it is only natural to assist one's fellow-creatures, this scene touched me, for hitherto I had seen the Germans commit rough, inhuman deeds only.Sixth.Inherent, or cooling strains, that may either spring and warp castings, or weaken them by maintained tension in certain partsa condition that often requires a disposition of the metal quite different from what working strains demand.
