ENGLISH СƵKeeping this in view, and referring to an ordinary planing machine with which the reader is presumed to be familiar, the focal point of the cutting strain is at the edge of the tools, and radiates from this point as from a centre to the various parts of the machine frame, and through the joints fixed and movable between the tools and the frame; to follow back from this cutting point through the mechanism to the frame proper; first starting with the tool and its supports and going to the main frame; then starting from the material to be planed, and following back in the other direction, until we reach the point where the strains are absorbed by the main frame, examining the joints which intervene in the two cases, there will appear some reasons for running carriages.Nor did I see any inhabitants in the burning78 town. It was practically impossible to stay in the streets; burning walls and roofs and gutters crashed down with a great noise, so that the streets were as much on fire as the houses themselves. Only at the crossings were any soldiers to be seen, who, in various stages of intoxication, constantly aimed at the burning houses, and shot everything that tried to escape from the burning stables and barns: pigs, horses, cows, dogs, and so on."What?"

Even before that, on August 11th I sent a communication, by post or cable (De Tijd, No. 20353), in which the following is found:A short distance beyond this little caf lies the large bridge across the Meuse. Before the Germans arrived it was partly destroyed by the Belgians, but so inadequately that obviously the enemy could repair it easily. Bombs were therefore fired regularly from Fort Pontisse at the bridge, and only an hour ago it had been hit, with the result that a big hole was made in the undamaged part. In the road also big holes were made by the exploding projectiles. Having passed underneath the viaduct of the bridge, I found myself opposite Vis on the sloping bank of the Meuse. Two boys had been commanded by the Germans to work the ferry-30boat for them, and after I had shown them my passport, they took me to the other side.

I think proper to point out these peculiarities, not so much from any importance they may have in themselves, but to suggest critical investigation, and to dissipate any preconceived opinions of forging being a simple matter, easy to learn, and involving only commonplace operations.Forging plant consists of rolling mills, trip-hammers, steam-hammers, drops, and punches, with furnaces, hearths, and blowing apparatus for heating. A general characteristic of all forging machines is that of a great force acting throughout a short distance. Very few machines, except the largest hammers, exceed a half-inch of working range, and in average operations not one-tenth of an inch.Machine motion is mainly rotary; and as rotary motion is accomplished by cylindrical parts such as shafts, bearings, pulleys and wheels, we find that the greater share of machine tools are directed to preparing cylindrical forms. If we note the area of the turned, bored and drilled surface in ordinary machinery, and compare with the amount of planed surface, we will find the former not less than as two to one in the finer class of machinery, and as three to one in the coarser class; from this may be estimated approximately the proportion of tools required for operating on cylindrical surfaces and plane surfaces; assuming the cutting tools to have the same capacity in the two cases, the proportion will be as three to one. This difference between the number of machines required for cylindrical and plane surfaces is farther increased, when we consider that tools act continually on cylindrical surfaces and intermittently on plane surfaces.

21"V. Henault.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.

From the other side came two soldiers, one of whom she recognised, as he had been billeted on her. Constantly weeping, her face distorted, she sent another glance towards that fiery blaze, looked at the soldier as if reprovingly, hesitated a moment, but then pressed the enemy's hand, sobbing: "Adieu!adieu!"6. Handling material in machine construction is one of the principal expenses to be dealt with; each time a piece is moved its cost is enhanced, and usually in a much greater degree than is supposed.The first and, perhaps, the most important matter of all in founding engineering works is that of arrangement. As a commercial consideration affecting the cost of manipulation, and the expense of handling material, the arrangement of an establishment may determine, in a large degree, the profits that may be earned, and, as explained in a previous place, upon this matter of profits depends the success of such works.

The Lige people were already up and about, and wandered through the streets full of fear, for all sorts of rumours were heardthat civilians were murdered, the town was to be burned down, and that a start would be made very soon. As they looked at those burning hamlets yonder they believed the rumours, and went nearly mad for fear; the men as well as the women could not help46 themselves, and wept. During the night various posters were stuck on the walls about military action. The following is the translation of one of these:"I must advise you not to, for it is extremely dangerous, but if you like...."

The successful application of the pneumatic system at the Mont Cenis Tunnel in Italy, and at the Hoosac Tunnel in America, has demonstrated the value of the system where the air not only served to transmit power to operate the machinery but to ventilate the mines at the same time. Air brakes for railway trains are another example illustrating the advantages of pneumatic transmission; the force being multiplied at the points where it is applied, so that the connecting pipes are reduced to a small size, the velocity of the air making up for a great force that formerly had to be communicated through rods, chains, or shafts. The principal object attained by the use of air to operate railway brakes is, however, to maintain a connection throughout a train by means of flexible pipes that accommodate themselves to the varying distance between the carriages. Presuming that the flow of air in pipes is not materially impeded by friction or angles, and that there will be no difficulty in maintaining lubrication for pistons or other inaccessible parts of machinery when driven by air, there seems to be many reasons in favour of its use as a means of distributing power in manufacturing districts. The diminished cost of motive power when [56] it is generated on a large scale, and the expense and danger of maintaining an independent steam power for each separate establishment where power is employed, especially in cities, are strong reasons in favour of generating and distributing power by compressed air, through pipes, as gas and water are now supplied.I had a rather amusing meeting at Tongres, with a Netherland colleague, who was on his way to Louvain.

In the meantime they themselves had a word or two to say about the fright I gave them; for when I stood at the door they mistook me in my sporting habit for a German officer, and the top of my water-bottle for the butt of a revolver!
