      (1.) Why are machine frames constructed in sections, instead of being in one piece?(2.) Why must parts which have contact on opposite sides have specific dimensions?(3.) What are standards of measure based upon in England, America, and France?(4.) How can weight be measured by time?(5.) Has the French metre proved a standard admitting of test reference?It is not intended to claim that this platen-reversing motion cannot, like any other mechanical movement, be resolved mathematically, but that the mechanical conditions are so obscure and the invention made at a time that warrants the supposition of accidental discovery.


      The frightened maidens were saying their rosary.


      Matters stood so in Lige on the morning of August 9th, when the second day of the occupation by the Germans had not yet passed. The Belgian field army, which had bravely defended the ground under the protection of the forts, and inflicted heavy losses upon the Germans, had to retreat before their superior numbers, leaving the further defence of the Meuse to the forts. But a high price had been paid for Lige, for the German losses were immense, and on the ninth they were still busy burying their dead. The Germans lost many men, especially near Lixhe and the Forts Bachon and Fleron.The road to The Netherlands was strewn over with empty wine-bottles.

      "Sister," I said then, "if you will only ask S?ur Eulalie to come to this gate she will recognise me, of course?"

      "Oh, but, sir, Wolff confirmed these reports."As to the manner of cutting out or planing up the lumber for patterns, and the manner of framing them together, it is useless to devote space to the subject here; one hour's practical observation in a pattern-shop, and another hour spent in examining different kinds of patterns, is worth more to the apprentice than a whole volume written to explain how these last-named operations are performed. A pattern, unless finished with paint or opaque varnish, will show the manner in which the wood is disposed in framing the parts together.


      It is exceedingly difficult for an apprentice engineer, without experimental knowledge, to choose plans for his own education, or to determine the best way of pursuing such plans when they have been chosen; and there is nothing that consumes so much time, or is more useless than attempting to make original designs, if there is not some systematic method followed.

      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.

      These and similar questions were asked after a superficial examination of my papers, and, having answered them, I was allowed to go on. But at a certain moment an officer appeared, who summoned me to dismount, and asked for my papers. After a short examination he ordered a soldier to take me to the commanding officer at Riemst.

      In conclusion, I will say on the subject of patterns and castings, that a learner must depend mainly upon what he can see and what is explained to him in the pattern-shop and foundry. He need never fear an uncivil answer to a proper question, applied at the right time and place. Mechanics who have enough knowledge to give useful information of their business, have invariably the courtesy and good sense to impart such information to those who require it.The importance of standard dimensions, and the effect which a system of gauging may have in the construction of machines, will be a matter of some difficulty for a learner to understand. The interchangeability of parts, which is the immediate object in employing gauges, is plain enough, and some of the advantages at once apparent, yet the ultimate effects of such a system extend much farther than will at first be supposed.
