From Vis I went again across the Meuse to the road along the canal. Nearing Haccourt, I noticed that Fort Pontisse was actually silent, but Lierce still in full action. The Germans had mounted long-range guns on the hills between Lancey and Haccourt, whence they could place Fort Lierce under fire. A German officer, after some coaxing, allowed me to witness the operations for a short time. I found a place near some heavy guns, and sat down amid some underwood. The shooting from Lierce was very fierce, but only by the plumes of smoke could I tell whereabouts the fort might be. The shells came down near us, but during the half hour of my stop not one made a hit. They all fell short of us.I did not answer. I could not. Silently I looked a little longer at the beastly scene, only sorry that I was not a giant who, with one strong hand, might restrain the roughs, and refresh with the other the burning, feverish lips of the wretched men.
IV.The steam cranes of Mr Morrison, which resemble hydraulic cranes, except that steam instead of water is employed as a medium for transmitting force, combine all the advantages of hydraulic apparatus, except positive movement, and evade the loss of power that occurs in the use of water. The elasticity of the steam is found in practice to offer no obstacle to steady and accurate movement of a load, provided the mechanism is well constructed, while the loss of heat by radiation is but trifling.In casting and forging operations the material is treated while in a heated and expanded condition; the nature of these operations is such that accurate dimensions cannot be attained, so that both forgings and castings require to be made enough larger than their finished dimensions to allow for shrinkage and irregularities. Finishing as a process consists in cutting away this surplus material, and giving accurate dimensions to the parts of machinery when the material is at its natural temperature. Finishing operations being performed as said upon material at its normal temperature permits handling, gauging and fitting together of the parts of machinery, and as nearly all other processes involve heating, finishing may be called the cold processes of metal work. The operations of a fitting shop consist almost entirely of cutting, and grinding or abrading; a proposition that may seem novel, yet these operations comprehend nearly all that is performed in what is called fitting.She came to herself again with a shudder and a feeling of anguish in every limb. She was not suspected yet, or even a fool of an English detective would not have shown her that picture. Broken and agitated as she was, her quick brain began to work again.
