FORE:There is, however, a principle in hydraulic machinery that must be taken into account, in comparing it with positively geared mechanism, which often leads to loss of power that in many cases will overbalance any gain derived from the peculiar action of hydraulic apparatus. I allude to the loss of power incident to dealing with an inelastic medium, where the amount of force expended is constant, regardless of the resistance offered. A hydraulic crane, for instance, consumes power in proportion to its movements, and not as the amount of duty performed; it takes the same quantity of water to fill the cylinders of such cranes, whether the water exert much or little force in moving the pistons. The difference between employing elastic mediums like air and steam, and an inelastic medium like water, for transmitting force in performing irregular duty, has been already alluded to, and forms a very interesting study for a student in mechanics, leading, as it does, to the solution of many problems concerning the use and effect of power.
THREE:"Bear up, lad! Keep courage; it will soon be different."
THREE:In the immediate neighbourhood of the railway station a house was being built, of which only the foundations were laid. The place showed nothing beyond a huge cavity. I had noticed already several times that there was an atrocious stench near the station, which at last became unendurable. Pastor Claes, who courageously entered all destroyed houses to look for the dead, had discovered the victims also in this place. In the cave just mentioned he found sixteen corpses of burghers, two priests among them. In order to remove them from the street the Germans had simply thrown them into that cave, without covering the corpses in any way. They had been lying there for days, and were decaying rapidly.
