A proof of this proposition is furnished in the case of standard machine tools for metal-cutting, a class of machinery that for many years past has received the most thorough attention at the hands of our best mechanical engineers.
Drawings represent and explain the machinery to which they relate as the symbols in algebra represent quantities, and in a degree admit of the same modifications and experiments to which the machinery itself could be subjected if it were already constructed. Drawings are also an important aid in developing designs or conceptions. It is impossible to conceive of, and retain in the mind, all the parts of a complicated machine, and their relation to each other, without some aid to fix the various ideas as they arise, and keep them in sight for comparison; like compiling statistics, the footings must be kept at hand for reference, and to determine the relation that one thing may bear to another.10 John Street, Adelphi,
ONE:I went up to them and explained that there was no need at all to be afraid of me. They were able to give me news of the inhabitants of Villa Rustica. The owner had died a few days since, from a paralytic stroke, brought on by the emotions caused by the German horrors, whereas madame, who had heroically intervened on behalf of some victims, was probably at St. Hadelin College.
ONE:The German officers at the commander's office were elated in consequence of the reports received, and also told me that Antwerp would not be able to hold out for more than two days. They also tried to explain this to the people in the hall who were waiting for their passports. I followed the conversation, but not very closely, and one of the officers explained on a map what he asserted. Willy-nilly, because they had to get their passports, the waiting people listened to him. Suddenly I heard him say: "And after all we might have surrounded Antwerp also on the north by crossing Netherland territory, as we did when we invaded Belgium."Waving to his two watching comrades as they grew smaller to his peering eyes, Larry turned his attention to the work of scanning, from the forward place, all the indented shore line, north, that the mist had uncovered.
TWO:They poured in thick and fast till the law intervened in the person of a posse of officials who represented the Sheriff of London, and then Hetty was permitted to pack up her belongings and those of the child and depart. Gilbert Lawrence received them with open arms. Bruce was there, pleased enough to get Hetty from the house where she had suffered so much. But there was a white despairing look that caused Hetty to forget her own troubles.
THREE:"An adventure!" the Countess cried gaily. "I have been dodging a couple of policemen, or I should have been back before. Beware of the high road. Goodbye, Captain, and if ever you wish to dispose of your Mercedes, give me the first offer."
