      Trip-hammers employed in forging bear a close analogy to, and were no doubt first suggested by, hand-hammers. Being the oldest of power-forging machines, and extensively employed, it will be proper to notice trip-hammers before steam-hammers."Did you ever see her?"


      In shading drawings, be careful not to use too deep tints, and to put the shades in the right place. Many will contend, and not without good reasons, that working drawings require no shading; yet it will do no harm to learn how and where they can be shaded: it is better to omit the shading from choice than from necessity. Sections must, of course, be shadednot with lines, although I fear to attack so old a custom, yet it is certainly a tedious and useless one: sections with light ink shading of different colours, to indicate the kind of material, are easier to make, and look much better. By the judicious arrangement of a drawing, a large share of it may be in sections, which in almost every case are the best views to work by. The proper colouring of sections gives a good appearance to a drawing, and conveys an idea of an organised machine, or, to use the shop term, "stands out from the paper." In shading sections, leave a margin of white between the tints and the lines on the upper and left-hand sides of the section: this breaks the connection or sameness, and the effect is striking; it separates the parts, [85] and adds greatly to the clearness and general appearance of a drawing.Lathes in common use for machine fitting are screw-cutting engine lathes, lathes for turning only, double-geared, single-geared, and back-geared lathes, lathes for boring, hand-lathes, and pulley-turning lathes; also compound lathes with double heads and two tool carriages.


      But it was not for long that Hetty remained like that. There was much to be done yet and much to learn. The thought of Gordon spurred her on. If she could get this woman into her power and force her to speak, all would be well. Hetty never doubted for a moment that Leona Lalage was at the bottom of her lover's misfortunes.

      Indeed, it was hardly to be expected that he would remain there for very long. As Gregg pointed out, such very delicate mechanism needed constant attention, and the unexpected was always likely to occur. There must have been some deeply-rooted automatism that gradually released the Clockwork man from his sleep; and having awakened, the grimy walls of the cellar no doubt struck him as distasteful. It was not to be expected that the Doctor, in his hurry and panic, should have succeeded in mastering the intricacies of the clock. He had merely brought about a[Pg 192] temporary quiescence which had gradually worked off. It had to be borne in mind, also, that although the Clockwork man was dependent upon adjustment in order that he should be made to work in a right fashion, it was only too plain that he could act independently and quite wrongly.The church we went to was in Franklin, but the preacher was a man of note, a Vicksburg refugee. On the way back Gholson and I rode for a time near enough to Squire Sessions and Ned Ferry to know the sermon was being discussed by them, and something they said gave my companion occasion to murmur to me in a tone of eager censure that Ned Ferry's morals were better than his religion.

      He pitched the glittering gauds contemptuously on the desk. Leona examined them carefully So far as she could see no change had been made. And where the stones had been filed she could see the dull scratched edges. Was this the work of the hidden enemy or another cruel stroke of ill fortune?To obtain a true understanding of the nature of power is by no means the difficulty for a beginner that is generally supposed [12]; and when once reached, the truth will break upon the mind like a sudden discovery, and ever afterwards be associated with mechanism and motion whenever seen. The learner will afterwards find himself analysing the flow of water, the traffic in the streets, the movement of ships and trains; even the act of walking will become a manifestation of power, all clear and intelligible, without that air of mystery that is otherwise inseparable from the phenomena of motion. If the learner will go on farther, and study the connection between heat and force, the mechanical equivalent of heat when developed into force and motion, and the reconversion of power into heat, he will have commenced at the base of what must constitute a thorough knowledge of mechanics, without which he will have to continually proceed under difficulties.


      A safe rule will be to assume that machinery mainly used and seen by the skilled should be devoid of ornament, and that machinery seen mainly by the unskilled, or in public, should have some ornament. Steam fire engines, sewing machines, and works of a similar kind, which fall under the inspection of the unskilled, are usually arranged with more or less ornament.

      Sitting in the open window, I marked the few red points of dying firelight grow fewer in the bivouac under the grove. Out there by the gate Ned Ferry slept. Fireflies blinked, and beyond the hazy fields rose the wasted moon, by the regal slowness of whose march I measured the passage of time as I had done two nights before. My vigil was a sad one, but, in health, in love, in the last of my teens and in the silent company of such a moon, my straying thoughts lingered most about the maiden who had "prayed for me." My hopes grew mightily. Yet with them grew my sense of need to redouble a lover's diligence. I resolved never again to leave great gaps in my line of circumvallation about the city of my siege, as I had done in the past--two days. I should move to the final assault, now, at the earliest favorable moment, and the next should see the rose-red flag of surrender rise on her temples; in war it is white, but in love it is red.

      Lawrence modestly disclaimed the compliment. As a strong romantic writer he found a fascination in crimes of this kind; indeed, he boasted that practically all his living dramas were founded on life. He had a wonderful faculty for tracing the motive of a crime Many a useful hint had he given to Scotland Yard.

      "What did she say," demanded the Doctor, irritably.
