FORE:Screw-cutting machines may be divided into modifications as follows:(1) Machines with running dies mounted in what is called the head; (2) Machines with fixed dies, in which motion is given to the rod or blank to be threaded; (3) Machines with expanding dies which open and release the screws when finished without running back; (4) Machines with solid dies, in which the screws have to be withdrawn by changing the motion of the driving gearing; making in all four different types."It is a pity, sir, that you did not arrive a day sooner, then you might have witnessed great barbarity of the Germans. If you walk on a little farther along the canal, you will see three persons hanging from a tree near Haccourt; one of these is a boy of fourteen. Nobody was allowed on the road, and as a patrol met these three persons, they concluded immediately that they were francs-tireurs, strung them up on the tree, without a trial of any sort, and in addition shot each a bullet through the head. To-day another patrol arrived and had the effrontery to tell the members of the Maastricht Red Cross that the boy had murdered a captain. And we are not allowed to remove the corpses. Horrible!... horrible!"
