      I will, in connection with this subject of patterns and castings, suggest a plan of learning especially applicable in such cases, that of adopting a habit of imagining the manner of moulding, and the kind of pattern used in producing each casting that comes under notice. Such a habit becomes easy and natural in a short time, and is a sure means of acquiring an extended knowledge of patterns and moulding.

      "Oh, no, indeed! I am the one to blame, the only one. If you had not, both of you, been so blameless--so splendidly blameless--I should hardly have let myself sink so deep into blame; but I knew you would never take the last glad step until you had seen the last sad proof that you might take it. Oh, Captain, to-night is the third time that in my dreams I have seen that man alive.""I don't know what I shall do, I'm sure," Arthur heard him say, as though to himself.

      Machines do not create or consume, but only transmit and apply power; and it is only by conceiving of power as a constant element, independent of every kind of machinery, that the learner can reach a true understanding of the nature of machines. When once there is in the mind a fixed conception of power, dissociated from every kind of mechanism, there is laid, so to speak, a solid foundation on which an understanding of machines may be built up.

      "Oh, go on!" I answered. "I don't think that I need fear anything of the kind. I am in any case a Netherlander!"

      They reached the kitchen window and looked out. There was a figure there, and what looked like another one in the background. A lantern stood on the flags; the first figure pitched something on the ground that looked like a coil of rope.

      "Oh, yes," she said slowly. "We were friends. I bear you no malice. But if I had only guessed--well, we should have seen something fresh in the way of obituary notices."

      "Now what does it mean?" he asked himself. "What game were they playing?"


      In cutting screws it is best not to refer to that mistaken convenience called a wheel list, usually stamped on some part of engine lathes to aid in selecting wheels. A screw to [127] be cut is to the lead screw on a lathe as the wheel on the screw is to the wheel on the spindle, and every workman should be familiar with so simple a matter as computing wheels for screw cutting, when there is but one train of wheels. Wheels for screw cutting may be computed not only quite as soon as read from an index, but the advantage of being familiar with wheel changes is very important in other cases, and frequently such combinations have to be made when there is not an index at hand.


      A sabreless officer with a bandaged hand flew up the stair and into my face. It was Helm. "The ladies! Smith, good God! Smith, where are the girls?"


      Maitrank grinned in sinister fashion.
