THREE:There is nothing more interesting, or at the same time more useful, in the study of mechanics, than to analyse the action of cutting machines or other machinery of application, and to ascertain in examples that come under notice whether the main object of a machine is increased force, more accurate guidance, or greater speed than is attainable by hand operations. Cutting machines as explained may be directed to either of these objects singly, or to all of them together, or these objects may vary in their relative importance in different operations; but in all cases where machines are profitably employed, their action can be traced to one or more of the functions named.

THREE:"I am probably the only man in the world who can help you," Lawrence replied. "To a certain extent I seem to have got you into this mess, and I must get you out of it. My dear young people, I am going to astonish you presently. Now, all I know up to now is that these notes have been traced to Bruce, and that, by a dreadful coincidence, he actually was one of the last people to see the murdered man before the tragedy. His little part Bruce has already told me, but I purposely asked no details. He has not yet informed me how the notes really reached his pocket, because the assumption that he stole them is ridiculous."
THREE:The use of hand tools should be learned by employing them on every possible occasion. A great many of the modern improvements in engine lathes are only to evade hand tool work, and in many cases effect no saving except in skill. A latheman who is skilful with hand tools will, on many kinds of light work, perform more and do it better on a hand lathe than an engine lathe; there is always more or less that can be performed to advantage with hand tools even on the most elaborate engine lathes.The meaning of this was all plain enough. Bruce had had his fee and was dismissed because these strange people were leaving for the Continent at once, provided the patient was well enough to travel. Suddenly the hall light went out again, and once more the house was in darkness. There was the sound of a heavy footfall outside. Bruce put his back to the wall prepared for eventualities.
