ENGLISH The first acquaintance whom I met on Netherland territory was a Netherland lady married to a Walloon, who kept a large caf at Vis. Before the destruction she had asked me, full of anxiety, whether the Germans would indeed carry out their86 threat and wreck everything. I had comforted her, and answered that I did not think them capable of doing such a thing. Weeping, she came to me, and reminded me of my words. The whole business, in which these young people had invested their slender capital, had been wrecked.In arranging the details of machines, it is impossible to have a special standard of dimensions for each case, or even for each shop; the dimensions employed are therefore made to conform to some general standard, which by custom becomes known and familiar to workmen and to a country, or as we may now say to all countries.

In respect to repairing alone, the consideration of having the parts of machinery fitted to standard sizes is often equal to its whole value.I had a short chat with the wounded men near the various houses, on demand showed my passport to those in authority, and was advised as a friendly Netherlander to return, as it was extremely dangerous on the road. But I did not dream of doing34 this, as long as I was not compelled, and went on towards Lige amidst this maddening thunder.

102I felt not the slightest inclination to go and see what was the matter, but I stretched myself and yawned, feeling much more tired after a couple of hours' rest than when I went to bed. The uproar went on, and suddenly I thought that I also heard a hubbub in the caf downstairs. And, really, it came ever nearer. People rushed up and down the stairs, screamed and yelled, doors were banged, in short it was as if they were pulling down the house.To this proposition another may be added, that shop processes may be systematised or not, as they consist in duplication, or the performance of certain operations repeatedly in the same manner. [101] It has been shown in the case of patterns that there could be no fixed rules as to their quality or the mode of constructing them, and that how to construct patterns is a matter of special knowledge and skill.

An apprentice in entering the workshop should avoid everything tending to an appearance of fastidiousness, either of manner or dress; nothing is more repulsive to workmen, and it may be added, nothing is more out of place in a machine shop than to divide one's time between the work and an attempt to keep clean. An effort to keep as neat as the nature of the work will admit is at all times right, but to dress in clothing not appropriate, or to allow a fear of grease to interfere with the performance of work, is sure to provoke derision."6. Eduard Peltzer, senator.

The difference between hand and machine operations, and the labour-saving effect of machines, will be farther spoken of in another place; the subject is alluded to here, only to enable the reader to more fully distinguish between machinery of transmission and machinery of application. Machinery of application, directed to what has been termed compression processes, such as steam hammers, drops, presses, rolling mills, and so on, act upon material that is naturally soft and ductile, or when it is softened by heat, as in the case of forging.Machine-drawing may in some respects be said to bear the same relation to mechanics that writing does to literature; persons may copy manuscript, or write from dictation, of what they do not understand; or a mechanical draughtsman may make drawings of a machine he does not understand; but neither such writing or drawing can have any value beyond that of ordinary labour. It is both necessary and expected that a draughtsman shall understand all the various processes of machine construction, and be familiar with the best examples that are furnished by modern practice.Once I enjoyed the pleasure of partaking of such a "dinner," as the guest of Professor and Mrs. Noyons. The company was very mixed, and men who never in their lives had ever done anything else but spoiling their eyes for the sake of science, by reading all manner of ancient manuscripts, were now busy, dressed in a blue apron, stirring the soup and mashing potatoes or vegetables. The menu comprised nothing but potatoes, a little vegetables, and a finely calculated piece of meat.

In the case of tools composed partly of iron and partly of steel, steel laid as it is called, the tendency to crack in hardening may be avoided in most cases by hammering the steel edge at a low temperature until it is so expanded that when cooled in hardening it will only contract to a state of rest and correspond to the iron part; the same result may be produced by curving a piece, giving convexity to the steel side before hardening."Yes, sir," I replied, "excepting my pocket-knife."

On August 25th the Antwerp garrison made a sortie, in the direction of Louvain. At the beginning the Belgians were successful, and came within four and a half miles of this town. For a moment the situation became critical, and at about seven o'clock a small troop of cavalry came at a furious gallop from the scene of battle to Louvain, probably to summon the assistance of the garrison.First.The power is connected to the hammer by means of the least possible mechanism, consisting only of a cylinder, a piston, and slide valve, induction pipe and throttle valve; these few details taking the place of a steam-engine, shafts, belts, cranks, springs, pulleys, gearing, in short, all such details as are required between the hammer-head and the steam-boiler in the case of trip-hammers or crank-hammers.
