      The intricacy of the subject renders it a difficult one to deal with except by the aid of diagrams, and as such mechanism may be inspected in almost any machine fitting shop, attention is called to the subject as one of the best that can be chosen for demonstration by diagrams. Problems of these variable speed movements are not only of great interest, but have a practical importance not found in many better known problems which take up time uselessly and have no application in a practical way.ぅ坤琳イI had to repeat everything about the advance of the French and the landing of the British, whilst they followed my story on the map. But I was soon in a cold sweat, for of course I knew practically nothing, neither of the French nor of the British, and each time when one of the officers pressed for details I was in mortal fear that I might contradict myself. But I stuck to my guns until the end, and assured them that the French had crossed the Belgian frontier near Givet, and were now near Namur, whereas the British, disembarking at Ostend, had advanced as far as Ghent.单ひThese conditions of short range and great force are best attained by what may be termed percussion, and by machines which act by blows instead of positive and gradual pressure; hence we find that hand and power hammers are the most common tools among those of the smith-shop.膝ョ

      To avoid imperfection in the running spindles of lathes, or any lateral movement which might exist in the running bearings, there have been many attempts to construct lathes with still centres at both ends for the more accurate kinds of work. Such an arrangement would produce a true cylindrical rotation, but must at the same time involve mechanical complication to outweigh the object gained. It has besides been proved by practice that good fitting and good material for the bearings and spindles of lathes will insure all the accuracy which ordinary work demands.モつIt is easy to learn "how" to draw, but it is far from easy to learn "what" to draw. Let this be kept in mind, not in the way of [79] disparaging effort in learning "how" to draw, for this must come first, but in order that the objects and true nature of the work will be understood.谜いゥ`氦ン�ワ护

      Reciprocating tools are divided into those wherein the cutting movement is given to the tools, as in shaping and slotting machines, and machines wherein the cutting movement is given to the material to be planed, as in a common planing machine. Very strangely we find in general practice that machine tools for both the heaviest and the lightest class of work, such as shaping, and butting, operate upon the first principle, while pieces of a medium size are generally planed by being moved in contact with stationary tools.イ楗`イ镌[50]ぺゥBut here he looked at me in a curious manner, scrutinising my face, as if he asked himself: "Is he pulling my leg, or not?" But not a muscle in my face moved, so that the "Captain" nodded approvingly ... and wrote out a pass for me to go to Visé! I was not allowed to go to Liège, for, as he said, he did not yet know himself how matters stood there. The other officers overwhelmed me with questions: how matters stood in The Netherlands, and whether Great Britain had already27 declared war against us? I think that at that question I looked utterly perplexed, for in the same breath they told me all they knew about the danger of war for The Netherlands: Great Britain first sent an ultimatum to The Netherlands, to force her into joining the Allies against Germany, and as she had refused, the British Fleet was now on its way to Flushing. I explained to them in detail that they were utterly wrong, but they believed only a half of what I said.ヨい糜

      "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:—骏炎枸ㄒ欷�谕去ゥい

      "It is a pity, sir, that you did not arrive a day sooner, then you might have witnessed great barbarity of the Germans. If you walk on a little farther along the canal, you will see three persons hanging from a tree near Haccourt; one of these is a boy of fourteen. Nobody was allowed on the road, and as a patrol met these three persons, they concluded immediately that they were francs-tireurs, strung them up on the tree, without a trial of any sort, and in addition shot each a bullet through the head. To-day another patrol arrived and had the effrontery to tell the members of the Maastricht Red Cross that the boy had murdered a captain. And we are not allowed to remove the corpses. Horrible!... horrible!"ゅゥい�閐坤A paralysed woman who had also been flung into the street was nursed at the hospital, and lay with many others in the chapel of the Institution, which had been turned into a ward.旆夸イ工

      �ぎ讴カよIt will be well for an apprentice to begin at once, as soon as he commences a shop course, to note the manner of handling material, watching the operation of cranes, hoists, trucks, tackle, rollers; in short, everything that has to do with moving and handling. The machinery and appliances in ordinary use are simple enough in a mechanical sense, but the principles of handling material are by no means as plain or easy to understand. The diversity of practice seen in various plans of handling and lifting weights fully attests the last proposition, and it is questionable whether there is any other branch of mechanical engineering that is treated less in a scientific way than machinery of this class. I do not allude to the mechanism of cranes and other devices, which are usually well proportioned and generally well arranged, but to the adaptation of such machinery with reference to special or local conditions. There are certain inherent difficulties that have to be encountered in the construction and operation of machinery, for lifting and handling, that are peculiar to it as a class; among these difficulties is the transmission of power to movable mechanism, the intermittent and irregular application of power, severe strains, also the liability to accidents and breakage from such machinery being controlled by the judgment of attendants.俾�い柯冥豫
