ENGLISH As these shop processes or operations are more or less connected, and run one into the other, it will be necessary at the beginning to give a short summary of them, stating the general object of each, that may serve to render the detailed remarks more intelligible to the reader as he comes to them in their consecutive order.Some makers of steam-hammers have so perfected the automatic class, that they may be instantly changed so as to work with either dead blows or elastic blows at pleasure, thereby combining all the advantages of both principles. This brings the steam-hammer where it is hard to imagine a want of farther improvement.

Movements come next in order, and consist of a reciprocating cutting movement of the tools or material, a feed movement to regulate the cutting action, and a longitudinal movement of the rack, graduated to pitch or space, the distance between the teeth.The German officers, of course, held a different opinion; they alleged that the shooting by the civilians was even very general and purported to be a decided attack on the army. I asked them whether they had found any rifles or other arms at the "searches" of the housesI expressed myself somewhat cautiously on purposefor that ought to have been the case if such a great number of citizens had joined in the shooting. "No," they answered, "they were sly enough to see to it that we did not find these. They had been buried in time, of course."I will now proceed to review these conditions or principles in pattern-making and casting in a more detailed way, furnishing as far as possible reasons for different modes of constructing patterns, and the various plans of moulding and casting.

It is evident that when the parts of a machine are joined together, each piece which has contact on more than one side must have specific dimensions; it is farther evident that as many of the joints in a machine as are to accommodate the exigencies of construction must be without space, that is, they represent continued sections of what should be solid material, if it were possible to construct the parts in that manner. This also demands specific dimensions.5. As the strength of shafts is determined by their size, and their size fixed by the strains to which they are subjected, [45] strains are first to be considered.

Beginning at the tool there is, first, a clamped joint between the tool and the swing block; second, a movable pivoted joint between the block and shoe piece; third, a clamped joint between the shoe piece and the front saddle; fourth, a moving joint [131] where the front saddle is gibed to the swing or quadrant plate; fifth, a clamp joint between the quadrant plate and the main saddle; sixth, a moving joint between the main saddle and the cross head; seventh, a clamp joint between the cross head and standards; and eighth, bolted joints between the standards and the main frame; making in all eight distinct joints between the tool and the frame proper, three moving, four clamped, and one bolted joint.I noticed the smell of fire already several miles from Louvain. On both sides of the road small mounds indicated the graves of soldiers who fell115 during the brave resistance of the Belgians before Louvain. A small wooden cross and some pieces of accoutrement were the only decorations. Carcases of horses were lying in the fields, from which came a disagreeable smell.

Upon entering the shop, a learner will generally, to use a shop phrase, "be introduced to a hammer and chisel;" he will, perhaps, regard these hand tools with a kind of contempt. Seeing other operations carried on by power, and the machines in charge of skilled men, he is likely to esteem chipping and filing as of but little importance and mainly intended for keeping apprentices employed. But long after, when a score of years has been added to his experience, the hammer, chisel, and file, will remain the most crucial test of his hand skill, and after learning to manipulate power tools of all kinds in the most thorough manner, a few blows with a chipping hammer, or a half-dozen strokes with a file, will not only be a more difficult test of skill, but one most likely to be met with."Oh, go on!" I answered. "I don't think that I need fear anything of the kind. I am in any case a Netherlander!"

This mode of reasoning will lead to proper estimates of the difference in value between good tools and inferior tools; the results of performance instead of the investment being first considered, because the expenses of operating are, as before assumed, usually ten times as great as the interest on the value of a machine.Between Thienen and Louvain I met endless trains of refugees, exactly like those I had seen already near Vis, Lige, and other places. These also carried their wretched bundles, and children and young people did their utmost to encourage and support their elders on their arduous path. All these people saluted me in a cringing, timid manner, nodding smilingly and taking off their caps already from afar.

After this game had been going on for some time, the order was given: "Everybody must come outside." Doors and windows were forced open and broken, and men, women, and children driven out of the houses. They were at once ruthlessly separated. Men who assisted their aged mothers, or carried their little babies, were taken away from their families, and driven away, leaving their wailing and weeping wives and children behind, while the flames from burning houses threw a lurid light on the sad scenes of that terrible evening.76This happened not only at Vis, but also at other places which I visited, more especially at Louvain. And those who read the following chapters carefully will find sufficient support for my opinion, that Belgium is innocent of the base charges and allegations uttered by Germany, which country soiled its conscience still worse, first by plunging the little kingdom into the direst misery, and then by accusing it falsely of crimes which it never committed.

In every quarter I met Belgian refugees from the south, and Netherlanders who wanted to escape to their safe native country. The Lige people themselves were not allowed to leave.The work of these sisters is the education of neglected children, and they spoke about their fears during the last momentous days. During the bombardment they stayed night and day with all those little ones in the heavily vaulted cellars of the nunnery, praying all the time before the Blessed Sacrament that had been removed from the chapel and taken into the cellar for safety.
