TWO:237"Well, I can and I can't," Lawrence said thoughtfully. "I'm puzzled, of course, and I am very much interested in this kind of thing. But really I am puzzled over one of the most remarkable coincidences that ever happened in the experience of a man who has made a pretty penny out of coincidences. In this instance 'the long arm' has taken a form that is positively uncanny."
TWO:Isometrical perspective is often useful in drawing, especially in wood structures, when the material is of rectangular section, and disposed at right angles, as in machine frames. One isometrical view, which can be made nearly as quickly as a true elevation, will show all the parts, and may be figured for dimensions the same as plane views. True perspective, although rarely necessary in mechanical drawing, may be studied with advantage in connection with geometry; it will often lead to the explanation of problems in isometric drawing, and will also assist in free-hand lines that have sometimes to be made to show parts of machinery oblique to the regular planes. Thus far the remarks on draughting have been confined to manipulation mainly. As a branch of engineering work, draughting must depend mainly on special knowledge, and is not capable of being learned or practised upon general principles or rules. It is therefore impossible to give a learner much aid by searching after principles to guide him; the few propositions that follow comprehend nearly all that may be explained in words.
TWO:"Ah, then, you must dissemble with her. Tell her any lie you like so long as you let Dr. Bruce alone. I guessed there was some scheme on hand when I heard that you had written to the Doctor. Goodbye, Wolffman, and recollect that your ruin or otherwise depends upon yourself."
