ENGLISH I do not refer to questions of mechanical construction, although the remark might be true if applied in this sense, but to the kind of devices that may be best employed in certain cases.

As I felt myself one with the population, I uncovered my head and enthusiastically joined in the cry: "Au revoir! Au revoir!"

In the case of line shafting for manufactories, if the speed varies so much from that of the first movers on machines as to require one or more intermediate or countershafts, the expense would be very great; on the contrary, if countershafts can be avoided, there is a great saving of belts, bearings, machinery, and obstruction. The practical limit of speed for line shafts is in a great measure dependent upon the nature of the bearings, a subject that will be treated of in another place."In agreement with the German Military authority I invite the inhabitants of Louvain to return to the city, and to take up again their usual occupations.I started on my return journey to The Netherlands sick to death. The consequences of lying on that wet floor made themselves badly felt, and besides being quite stiff and chilly, my interior was badly out of order.

A little farther on a few houses were left undamaged, because they stood outside the town proper. A woman who had remained in her house stood outside with cigar-boxes under her arm. She offered cigars from an open box to the soldiers of the passing divisions. To me she seemed to be out of her mind, as she stood there trembling, her face distorted from hypernervousness. Her cringing kindness was of no avail, for I noticed a couple of days afterwards that her house too had been totally destroyed.In multiplying the variations of a measuring implement by mechanism, it is obvious that movable joints must be employed; it is also obvious that no positive joint, whether cylindrical or flat, could be so accurately fitted as to transmit such slight movement as occurs in gauging or measuring. This difficulty is in most measuring instruments overcome by employing a principle not before alluded to, but common in many machines, that of elastic [151] compensation.

I started on my return journey to The Netherlands sick to death. The consequences of lying on that wet floor made themselves badly felt, and besides being quite stiff and chilly, my interior was badly out of order.The poor man wept, and, although I had taken with me no more than two pieces of bread-and-butter, which I had not touched yet, I could not bear the sight of these poor, hungry things, and handed over to them my food.

"All right, sir."On the same day I wrote as follows about Dr. Goffin:The general principles of hammer-action, so far as already explained, apply as well to hammers operated by direct steam; and a learner, in forming a conception of steam-hammers, must not fall into the common error of regarding them as machines distinct from other hammers, or as operating upon new principles. A steam-hammer is nothing more than the common hammer driven by a new medium, a hammer receiving power through the agency of steam instead of belts, shafts, and cranks. The steam-hammer in its most improved form is so perfectly adapted to fill the different conditions required in power-hammering, that there seems nothing left to be desired.

To an experienced mechanic a single glance at the tools on a lathe is a sufficient clue to the skill of the operator. If the tools are ground ready to use, of the proper shape, and placed in order so as to be reached without delay, the latheman may at once be set down as having two of the main qualifications of a first-class workman, which are order, and a knowledge of tools; while on the contrary, a lathe board piled full of old waste, clamp bolts, and broken tools, shows a want of that system and order, without which no amount of hand skill can make an efficient workman.Women and children had frequently been ill-treated in a most atrocious manner, aged and sick people were dragged out of the houses, and flung down in the street. This happened, for example, to an old man, who lay dying in his cellar. In spite of the supplications of his wife and two sons, he was flung on the cobbles, where he died soon. The sons were taken prisoners and sent away. His widow assists at present nursing other unfortunates at Professor Noyons' hospital.

Most of the difficulties which formerly pertained to drilling are now removed by machine-made drills which are manufactured and sold as an article of trade. Such drills do not require dressing and tempering or fitting to size after they are in use, make true holes, are more rigid than common solid shank drills, and will drill to a considerable depth without clogging.
