A paralysed woman who had also been flung into the street was nursed at the hospital, and lay with many others in the chapel of the Institution, which had been turned into a ward.
They took me to two officers who stood near the bridge, and told them that I "pretended" to be a Netherland journalist. Having proved this by my papers, the officers gave me an escort of three men, who conducted me to the bridge-commander, on the other side of the Meuse.
At the risk of laying down a proposition not warranted by science, I will mention, in connection with this matter of crystallisation, that metal when disposed in the form of a ring, for some strange reason seems to evade the influences which produce crystalline change. A hand-hammer, for example, may be worn away and remain fibrous; the links of chains and the tires of waggon wheels do not become crystallised; even the tires on locomotive wheels seem to withstand this influence, although the conditions of their use are such as to promote crystallisation.
And during these first days of the war I had not met a single person who was able to settle down quietly in the existing circumstances, not a single person in whom anger and fury subdued fear and terror.
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.
Different kinds of gearing can be seen in almost every engineering establishment, and in view of the amount of scientific information available, it will only be necessary to point out some of the conditions that govern the use and operation of the different kinds of wheels. The durability of gearing, aside from breaking, is dependent upon pressure and the amount of rubbing action that takes place between the teeth when in contact. Spur wheels, or bevel wheels, when the pitch is accurate and the teeth of the proper form, if kept clean and lubricated, wear but little, because the contact between the teeth is that of rolling instead of sliding. In many cases, one wheel of a pair is filled with wooden cogs; in this arrangement there are four objects, to avoid noise, to attain a degree of elasticity in the teeth, to retain lubricants by absorption in the wood, and to secure by wear a better configuration of the teeth than is usually attained in casting, or even in cutting teeth.
