      ��Referring first to the saving effected by combining several operations in one machine, there is perhaps not one constructor in twenty that ever stops to consider what is really gained, and perhaps not one purchaser in a hundred that does the same thing. The impression is, that when one machine performs two operations it saves a second machine. A remarkable example of this exists in the manufacture of combination machines in Europe for working wood, where it is common to find complicated [69] machines that will perform all the operations of a joiner's shop, but as a rule only one thing at a time, and usually in an inconvenient manner, each operation being hampered and interfered with by another; and in changing from one kind of work to another the adjustments and changes generally equal and sometimes exceed the work to be done. What is stranger still is, that such machines are purchased, when their cost often equals that of separate machines to perform the same work.

      ��For the rest most houses in the market-place were on fire. Soldiers were billeted on one of the corner houses, and I was of course detained there, but released again, after having been requested to show up the francs-tireurs. I had to consider also where I might pass the night in this burning city? I asked an officer's consent to stay the night with the soldiers. He gave his permission if I could get the consent of the commanding officer, whom I might find at the station; he told me that he was sure to grant it.

      Upon entering the shop, a learner will generally, to use a shop phrase, "be introduced to a hammer and chisel;" he will, perhaps, regard these hand tools with a kind of contempt. Seeing other operations carried on by power, and the machines in charge of skilled men, he is likely to esteem chipping and filing as of but little importance and mainly intended for keeping apprentices employed. But long after, when a score of years has been added to his experience, the hammer, chisel, and file, will remain the most crucial test of his hand skill, and after learning to manipulate power tools of all kinds in the most thorough manner, a few blows with a chipping hammer, or a half-dozen strokes with a file, will not only be a more difficult test of skill, but one most likely to be met with.�

      �5. Hydraulic machinery comes nearest to filling the required conditions in handling material, and should be employed in cases where the work is tolerably uniform, and the amount of handling will justify the outlay required.Having 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.

      �In studying improvements with a view to practical gain, a learner can have no reasonable hope of accomplishing much in fields already gone over by able engineers, nor in demonstrating anything new in what may be called exhausted subjects, such as steam-engines or water-wheels; he should rather choose new and special subjects, but avoid schemes not in some degree confirmed by existing practice.Drilling differs in principle from almost every other operation in metal cutting. The tools, instead of being held and directed by guides or spindles, are supported mainly by the bearing of the cutting edges against the material.

      "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:—Details and sketches, when made on a separate sheet, should be to a larger scale than elevations. By changing from one scale to another the mind is schooled in proportion, and the conception of sizes and dimensions is more apt to follow the finished work to which the drawings relate."V. Henault.

      Workshop processes which are capable of being systematised are the most easy to learn. When a process is reduced to a system it is no longer a subject of special knowledge, but comes within general rules and principles, which enable a learner to use his reasoning powers to a greater extent in mastering it.Designing machines must have reference to adaptation, endurance, and the expense of construction. Adaptation includes the performance of machinery, its commercial value, or what the machinery may earn in operating; endurance, the time that machines may operate without being repaired, and the constancy of their performance; expense, the investment represented in machinery.He did not seem to mind much the destruction of the Halls with their world-famous wealth of books; anyway he spoke about it in an unconcerned tone. But he seemed to attach great importance to the safety of the town-hall. He said that when the buildings adjoining the town-hall began to burn, he had them blown up in order to keep the fire away from the beautiful monument.
