      �ԷۥA common angular-pointed drill is capable of withstanding a greater amount of strain upon its edges, and rougher use than any other cutting implement employed in machine fitting. The rigid support which the edges receive, and the tendency to press them to the centre, instead of to tear them away as with other tools, allows drills to be used when they are imperfectly shaped, improperly tempered, and even when the cutting edges are of unequal length.㥤Labourers were called up to assist in reinforcing the conquered forts on the left bank of the Meuse, the forts which by and by might be used to shell their fellow-countrymen, in case the Germans should be forced to retire. Nobody will have offered himself for this work voluntarily, the less so as the proclamation wound up as follows:—ܤ

      Let the reader compare a hammer with a wheel and axle, inclined plane, screw, or lever, as an agent for concentrating and applying power, noting the principles of its action first, and then considering its universal use, and he will conclude that, if there is a mechanical device that comprehends distinct principles, that device is the common hammer. It seems, indeed, to be one of those provisions to meet a human necessity, and without which mechanical industry could not be carried on. In the manipulation of nearly every kind of material, the hammer is continually necessary in order to exert a force beyond what the hands may do, unaided by mechanism to multiply their force. A carpenter in driving a spike requires a force of from one to two tons; a blacksmith requires a force of from five pounds to five tons to meet the requirements of his work; a stonemason applies a force of from one hundred to one thousand pounds in driving the edge of his tools; chipping, calking, in fact nearly all mechanical operations, consist more or less in blows, such blows being the application of accumulated force expended throughout a limited distance.ݤ�餩ŵ٤Chasing produces screws true with respect to their axis, and is the common process of threading all screws which are to have a running motion in use, either of the screw itself, or the nut.

      "Every attack on German troops by others than the military in uniform not only exposes those who may be guilty to be shot summarily, but will also bring terrible consequences on leading citizens of Liège now detained in the citadel as hostages by the Commander of the German troops. These hostages are:—ѥᤤAfter giving them some advice how to get to The Netherlands, and offering some words of sympathy, I wanted to go on, but as they realised this, the poor, kind creatures surrounded me; many women began to weep, and from all sides they cried:ݤ즥"No, sir, we must hope for the best."夥

      �ۥThat I was "wanted" is proved by the fact that two persons have had the greatest trouble because they were mistaken for the Mokveld-Correspondent of De Tijd.

      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.٥ߤ�Ѥ

      (1.) Why have belts been found better than shafts for transmitting power through long distances?—(2.) What are the conditions which limit the speed of belts?—(3.) Why cannot belts be employed to communicate positive movement?—(4.) Would a common belt transmit motion positively, if there were no slip on the pulleys?—(5.) Name some of the circumstances to be considered in comparing belts with gearing or shafts as a means of transmitting power.ʥ礥�åIt has been alleged that civilians had been shooting from the Halls, but when a committee examined the remains in the building with the consent of the military, they found there the carcase of a German horse. They were ordered to stop their investigations immediately, for that horse was evidence ... that German military men had been billeted on the building, and thus no civilians could have been there. This will also be published later in the reports.椤٤

      "You are a journalist?"�˥ͤIt was a chilly night, and a dense heavy fog made it impossible to see anything.... My "bed-fellows" raged and fumed at me, saying that I was one of those villains who had treacherously shot at them. I shivered from the cold, and felt, as it were,128 the dampness of the wet stone floor entering my system.Ǥ

      �ܩΥIn practice, the truth of this proposition is fully demonstrated by the excess in the number of lathes and boring tools compared with those for planing.ȴA common angular-pointed drill is capable of withstanding a greater amount of strain upon its edges, and rougher use than any other cutting implement employed in machine fitting. The rigid support which the edges receive, and the tendency to press them to the centre, instead of to tear them away as with other tools, allows drills to be used when they are imperfectly shaped, improperly tempered, and even when the cutting edges are of unequal length.ٷեƤ

The cutting position should be so arranged as to admit of an easy inspection of the work. An operator having to keep his hand on the adjusting or feed mechanism, which is about twelve inches above the work, it follows that if the cutting level is four feet from the floor, and the feed handle five feet from the floor, the arrangement will be convenient for a standing position. As the work requires continual inspection and hand adjustments, it will for this reason be a proper arrangement to overhang both the supports for the rack and the cutting tools, placing them, as we may say, outside the machine, to secure convenience of access and to allow of inspection. [156] The position of the cutting bar, crank, connections, gearing, pulleys, and shafts, will assume their respective places from obvious conditions, mainly from the position of the operator and the work.ƥ`On the same day I wrote as follows about Dr. Goffin:—ܤ̤
