FORE:Tangent wheels and spiral gearing have only what is termed line contact between the bearing surfaces, and as the action between these surfaces is a sliding one, such wheels are subject to rapid wear, and are incapable of sustaining much pressure, or transmitting a great amount of power, except the surfaces be hard and lubrication constant. In machinery the use of tangent wheels is mainly to secure a rapid change of speed, usually to diminish motion and increase force.Only now did I hear what had happened to the village of Lanaeken after I had seen the German preparations in Tongres for action against the little Belgian army that was still about in the north-eastern part of the country. The greater part of Lanaeken had been destroyed by shelling, and of course a great many innocent victims had fallen in consequence.
FORE:Round about Louvain everything was prepared for defensive purposes, artillery being hidden under straw-roofs, only a few yards away from the farm-houses, and the sentries were very alert. I never saw them before I was quite near; then they jumped suddenly from behind a tree, summoning me to stop by lowering their rifle. In the meadows were a good many newly cut trenches.Bicycling was of course out of the question; I shouldered my bicycle and stepped across the glowing cinders, which singed my soles. One spot could still be recognised as a street corner. Three soldiers emerged there suddenly and aimed at me with their rifles.
