      "Of course!" he said; "of course! But, Smith, my mind was so full--just for the moment, you know,--of her we were speaking of in connection with Ned Ferry--Do you know? she's so unprotected and tagged after and talked about that it seems to me sometimes, in this nervous condition of mine, that if I could catch the entire gang of her pursuers in one hole I'd--I'd end 'em like so many rats. That sort of feeling is mere impulse, of course," he went on, "and only shows how near I am to that nervous breakdown. Yes, the Harper ladies are mighty lovely and hard enough to leave, but that's all I meant to you, and I'm sorry I touched your feelings. I'm tchagrined. Anyhow, all this is between us, you know. I wouldn't ever have confessed such feelings as I did just now except to a friend who knows as well as you do that if I ever should do a man a mortal injury I wouldn't do it in a spirit of resentment. You know that, don't you? No, that's not my way--Why, Smith, what gives you those starts? That's the third time you've done that this morning."3. The valve must move after the hammer stops.

      Arthur was startled back to common sense. "They don't," he whispered, as they held one another in trembling arms. "If they did they would be like us.""Quite, sir," the lawyer responded. "According to the papers drawn up at the time, you can take possession and demand your money at any moment. You are in the same position as a landlord distraining for rent. If you want us to act----"

      "If you like," admitted Gregg, "only it does help them to understand, just as all our scientific knowledge helps us to understand, the future.""I promise nothing. You are in no position to dictate terms. Sit down and tell me the history of the forgery."

      It is no uncommon thing for a skilled latheman to lock the slide rest, and resort to hand tools on many kinds of work when he is in a hurry.These are, however, not the only reasons which have led to a running platen for planing machines, although they are the most important.

      "You have given me some valuable clues," he said. "In the first place we now know the real name of the murdered man. Strange that it should be the same as the fascinating Countess! And stranger still that our brilliant adventuress did not call herself something else when she engineered herself into society. But probably that is part of the reckless audacity of her nature. It was very foolish, because it clogs up the brains of a man like myself who has knocked about artistic and theatrical London for so long. And I distinctly recollect a Lalage, a dancer, who made a hit at the halls some seven or eight years ago."


      "Are there more horrors to come, dearest?"Clickclickclickerty clickclicker clickerclicker And so on, becoming louder and louder until at last it stopped, and its place was taken by the dull pitter-patter of footsteps coming nearer and nearer. There was a little harsh snort that might have been intended for a sigh, and then a voice.


      To make this plainer, the laws of forces, the proportion of parts, strength of material, and so on, are subjects of general knowledge that may be acquired from books, and understood without the aid of an acquaintance with the technical conditions of either the mode of constructing or the manner of operating machines; but how to construct proper patterns for castings, or how the parts of machinery should be moulded, forged, or fitted, is special knowledge, and must have reference to particular cases. The proportions of pulleys, bearings, screws, or other regular details of machinery, may be learned from general rules and principles, but the hand skill that enters into the manufacture of these articles cannot be learned except by observation and experience. The general design, or the disposition of metal in machine-framing, can be to a great extent founded upon rules and constants that have general application; but, as in the case of wheels, the plans of moulding such machine frames are not governed by constant rules or performed in a uniform manner. Patterns of different kinds may be employed; moulds may be made in various ways, and at a greater and less expense; the metal can be mixed to produce a hard or a soft casting, a strong or a weak one; the conditions under which the metal is poured may govern the soundness or shrinkage,things that are determined by special instead of general conditions.


      Machines with direct action, such as punches, shears, or rolls, require first a train of mechanism of some kind to reduce the motion from the driving power so as to attain force; and secondly, [105] this force must be balanced or resisted by strong framing, shafts, and bearings. A punching-machine, for example, must have framing strong enough to resist a thrust equal to the force applied to the work; hence the frames of such machines are always a huge mass, disposed in the most advantageous way to meet and resist this reactive force, while the main details of a drop-machine capable of exerting an equal force consist only of a block and a pair of guides to direct its course.


      "Good-morning," he responded, tardily and grimly. "Well, you air in a hurry."
