      �ƤץMr. Derricks lived at Roelanche, but with his wife and seven children had fled for security to Canne, where he was hospitably received in Mr. Poswick's, the burgomaster's, house.cӤHaving walked some thirty miles that day, I began to feel a serious need for rest. But when I applied, there was no room anywhere in the hotels, and where there was room they told me the contrary after a critical glance at my outfit.

      This will form an interesting collection of specimens and accustom the eye to the various tints, which after some experience will be instantly recognised when seen separately.𥥤夤He pointed to a couple of soldiers, and they laid hold of me. They took me to a small room, where I was astonished to find two soldiers with revolvers guarding a priest and a peasant. As soon as the door was closed behind me I wished to chat with my fellow-prisoners, for even in prison I was not oblivious of my journalistic duties. But they seemed not at all anxious to have anything to do with me, and I soon understood the reason why. At each question they threw timid glances at the two watch-dogs, and I saw that fear of these made them withhold all information. However, after a good deal of trouble I got to know that the priest was the parish priest, and his companion in misery the burgomaster. They had been taken as hostages, and would suffer punishment for acts the villagers might eventually commit against the German usurpers. I contented myself with this, as I felt104 that in the circumstances further questions might make things awkward for these two men.륲Considered upon grounds of commercial expediency as a question of cost alone, it is generally cheaper to move material by hand when it can be easily lifted or moved by workmen, when the movement is mainly in a horizontal direction, and when the labour can be constantly employed; or, to assume a general rule which in practice amounts to much the same thing, vertical lifting should be done by motive power, and horizontal movement for short distances performed by hand. There is nothing more unnatural than for men to carry loads up stairs or ladders; the effort expended in such cases is one-half or more devoted to raising the weight of the body, which is not utilised in the descent, and it is always better to employ winding or other mechanism for raising weights, even when it is to be operated by manual labour. Speaking of this matter of carrying loads upward, I am reminded of the fact that builders in England and America, especially in the latter country, often have material carried up ladders, while in some of the older European countries, where there is but little pretension to scientific manipulation, bricks are usually tossed from one man to another standing on ladders at a distance of ten to fifteen feet apart.`


      3. A knowledge of specific conditions, such as strains, the range and rate of movements, and so on.Τ"But, madame, I am not German; I am a Netherlander. I should...."߷帻`ON THE WAY TO LIèGEΥ֥٪

      I shuddered at the thought that in these days such barbarities were possible. I asked the soldiers whether I was allowed to enter the burning village, but the commanding sergeant refused his consent.إť餤In operating by elastic blows, the steam piston is cushioned at both the up and down stroke, and the action of a steam-hammer corresponds to that of a helve trip-hammer, the steam filling the office of a vibrating spring; in this case a hammer gives a quick rebounding blow, the momentum being only in part [111] spent upon the work, and partly arrested by cushioning on the steam in the bottom of the cylinder under the piston.⤭󾤨�


      The most effectual means of securing a uniform effect from a tempering bath is by violent agitation, either of the bath or the piece; this also adds to the rapidity of cooling.륥�Ťdԣ

      So I thought that I might chance it. The house was some distance from the station, near the railway line; opposite stood a sort of goods station guarded by six soldiers. Before entering the house I had a chat with them, for I thought that if I explained my position and told them that the commanding officer gave me permission to pass the night in that house, I should be much safer if anything should happen during the night, because they knew then that they had to deal with a neutral journalist. They might moreover warn me should the fire that was raging all around reach that house. So I told the whole story to these fellows, who were also more than half drunk, showed them my passports, gave them some cigars, and after a friendly chat went123 to the old man who was to put me up for the night."Indeed! And did you take notes already? Just let me have a look."ܥ CHAPTER IXܤ饺

      Tempering may be called a mystery of the smith-shop; this operation has that attraction which characterises every process that is mysterious, especially such as are connected with, or belong to mechanical manipulation. A strange and perhaps fortunate habit of the mind is to be greatly interested in what is not well understood, and to disregard what is capable of plain demonstration.ʥ`To direct the attention of learners to certain rules that will guide them in forming opinions in this matter of machine combination, I will present the following propositions, and afterwards consider them more in detail:—륧Expedients to avoid dirt in such castings as are to be finished all over or on two sides are various. Careful moulding to avoid loose sand and washing is the first requisite; sinking heads, that rise above the moulds, are commonly employed when castings are of a form which allows the dirt to collect at one point. Moulds for sinking heads are formed by moulders as a rule, but are sometimes provided for by the patterns.


      "I know that those rumours have been spread about, but also that they were contradicted by Belgian officials. I know also, and can affirm it from my own personal observation, that there is not a single word of truth in those accusations, for I passed the early days of the war in the district where the fight was going on."쥥The engineering apprentice, as a rule, has a desire to make drawings as soon as he begins his studies or his work, and there is not the least objection to his doing so; in fact, there is a great deal gained by illustrating movements and the details of machinery at the same time of studying the principles. Drawings if made should always be finished, carefully inked in, and memoranda made on the margin of the sheets, with the date and the conditions under which the drawings were made. The sheets should be of uniform size, not too large for a portfolio, and carefully preserved, no matter how imperfect they may be. An apprentice who will preserve his first drawings in this manner will some day find himself in possession of a souvenir that no consideration would cause him to part with.`ۥإStrains suggest special arrangement, which is quite a distinct matter from general arrangement, the latter being governed mainly by the convenience of manipulation. Special arrangement deals with and determines the shape of framing, following the strains throughout a machine. In the present case we have a cutting strain which may be assumed as equal to one ton, exerted between the bracket or jaws which support the work, and the crank-shaft. It follows that between these two points the metal in the framing should be disposed in as direct a line as possible, and provision be made to resist flexion by deep sections parallel with the cutting motion.

      �·奼In Liège things were no longer so depressing as at the time of my first visit. There was some traffic in the streets, and by order of the German authorities the shops had been reopened.`"Possibly! Not allowed!"
