The title of a drawing is a feature that has much to do with its appearance, and the impression conveyed to the mind of an observer. While it can add nothing to the real value of a drawing, it is so easy to make plain letters, that the apprentice is urged to learn this as soon as he begins to draw; not to make fancy letters, nor indeed any kind except plain block letters, which can be rapidly laid out and finished, and consequently employed to a greater extent. By drawing six parallel lines, making five spaces, and then crossing them with equidistant lines, the points and angles in block letters are determined; after a little practice, it becomes the work of but a few minutes to put down a title or other matter on a drawing so that it can be seen and read at a glance in searching for sheets or details.
And now the explanation? During the night the Germans had started house-to-house searches, and wherever the doors were not opened quickly enough, the soldiers began to shoot. The inhabitants were then driven into the street amid loud screams and cries. It was also said that some persons had been shot.
The German authority left indeed no effort untried to cover up their atrocious action. Already in a communication from Wolff, dated August 29th, they attempted to violate the truth by asserting that:—
Mr Ransome of Ipswich, England, where this system of template moulding originated, has invented a process of fitting templates for gear wheels and other kinds of casting by pouring melted white metal around to mould the fit instead of cutting it through the templates; this effects a great saving in expense, and answers in many cases quite as well as the old plan.
Connected with screw dies, there are various problems, such as clearance behind the cutting edge; whether an odd or even number of edges are best; how many threads require to be bevelled at the starting point; and many other matters about which there are no determined rules. The diversity of opinion that will be met with on these points, and in reference to taps, the form of screw-threads, and so on, will convince a learner of the intricacies in this apparently simple matter of cutting screw-threads.
On one of the hills, slightly to the south of Haccourt, on the west bank of the Meuse and the canal, a German battery was firing at Fort Pontisse. The gunners there were quite kind, and they felt no fear at all, for although they shelled the fort continuously, it seemed that nothing was done by way of reply to their fire. The shells from the fort flew hissing over our heads, in the direction of Lixhe, which proved that Fort Pontisse was still chiefly busy with the pontoon-bridge at that place.
