Hetty nodded. She perfectly understood. And Bruce had often told her that she was one of the best nurses he had ever met. There was nothing to do for the moment beyond watching over the patient to see that no change occurred.Not only had they given in. Jeff, it appeared, had given up. In thickening mist the risks were too great.But he did not take any notice of all my exhortations and was entirely impervious to them in his grief. So I went to the station side by side with the weeping man, and surrounded by the six soldiers. The crackle of the flames, the sound of collapsing houses seemed more terrifying in the night than in day-time, and now and again I got a shock when suddenly, by the uncertain light of the flames, I saw the corpse of a civilian lying in the dark shade of the tall trees on the Boulevard.On Monday, September 14th, I took with me a larger number than ever to Louvain.Other soldiers kept on running into the burning houses, carrying out vases, pictures, plate, or small pieces of furniture. They smashed everything on81 the cobbles and then returned to wreck more things that would have been destroyed by the fire all the same. It was a revelry of drunken vandalism. They seemed mad, and even risked being burned alive at this work of destruction. Most of the officers were also tipsy; not one of them was saluted by the soldiers.These different plans will be considered first in reference to the effect produced upon the movement of carriages; this includes friction, endurance of wear, rigidity of tools, convenience of operating and the cost of construction. The cutting point in both turning and boring on a slide lathe is at the side of a piece, or nearly level with the lathe centres, and any movement of a carriage horizontally across the lathe affects the motion of the tool [124] and the shape of the piece acted upon, directly to the extent of such deviation, so that parallel turning and boring depend mainly upon avoiding any cross movement or side play of a carriage. This, in both theory and practice, constitutes the greatest difference between flat top and track shears; the first is arranged especially to resist deviation in a vertical plane, which is of secondary importance, except in boring with a bar; the second is arranged to resist horizontal deviation, which in nine-tenths of the work done on lathes becomes an exact measure of the inaccuracy of the work performed.
