ENGLISH I was the only civilian in that road, and the soldiers, with much curiosity, stared at me. Whenever I noticed an officer, I gave an elaborate military salute, and with such an air that the officers, although hesitating at first, did not fail to return the salute.The bridge-command at the pontoon-bridge near Lixhe allowed me to cross, after requesting me very pressingly to make very clear what swine these Belgians were, who fired so treacherously at unsuspecting soldiers, put out the eyes of the wounded, cut off their hands and genitals. When I asked where all these things had happened, the answer was: "Everywhere!" Of course, I promised them to do everything they wanted.I was not allowed to return by bicycle, and left it at a caf at the crossing of the roads to Tongres and Riemst. A couple of days later the Germans had already abstracted the tyres.

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.Her reserve told me that I would not get much information here, and, finishing my beer, I asked:

CHAPTER IXCHAPTER XII. BELTS FOR TRANSMITTING POWER.

(1.) What does the term "machinery of transmission" include, as applied in common use?(2.) Why cannot direct comparisons be made between shafts, belts, and gearing?(3.) Define the relation between speed and strain in machinery of transmission.(4.) What are the principal conditions which limit the speed of shafts?The gauging system has been no little retarded by a selfish and mistaken opinion that an engineering establishment may maintain peculiar standards of its own; in fact, relics of this spirit are yet to be met with in old machines, where the pitch of screw-threads has been made to fractional parts of an inch, so that engineers, other than the original makers, could not well perform repairing, or replace broken parts.Quickly he summoned an orderly and gave some orders, and a few minutes later four more officers drew round the table, on which a large map of Belgium was displayed. Their tone became at once charmingly sweet and kind, and a soldier offered me some lemonade from small bottles kept cool in a basin filled with cold water.

These various lathes, although of a widely varied construction and adapted to uses more or less dissimilar, are still the engine lathe either with some of its functions omitted to simplify and adapt it to some special work, or with some of the operative parts compounded to attain greater capacity.This principle is somewhat obscure, and the nature of percussive forces not generally considereda matter which may be illustrated by considering the action of a simple hand-hammer. Few [103] people, in witnessing the use of a hammer, or in using one themselves, ever think of it as an engine giving out tons of force, concentrating and applying power by functions which, if performed by other mechanism, would involve trains of gearing, levers, or screws; and that such mechanism, if employed instead of a hammer, must lack that important function of applying force in any direction as the will and hands may direct. A simple hand-hammer is in the abstract one of the most intricate of mechanical agentsthat is, its action is more difficult to analyse than that of many complex machines involving trains of mechanism; yet our familiarity with hammers causes this fact to be overlooked, and the hammer has even been denied a place among those mechanical contrivances to which there has been applied the name of "mechanical powers."

At that dinner I also made the acquaintance of Professor Nerincx, the acting burgomaster. It was a courageous act to assume the government of the town destroyed by the Germans; he did it for the sake of his fellow-citizens, who will never be able to requite their indebtedness to the temporary burgomaster for what he did for them; and most of them do not even know it.49

The wind seemed to play with the smoke, rolling dense volumes down the slopes which dispersed only when they reached the bank along the river. Whilst the flames soared high up from the roofs, the walls of the houses stood still erect, and everywhere in the windows one saw those miserable little white flags, symbols of submission, mute prayers75 that submission should be rewarded by sparing the life and possession of the inhabitants....
