rs. In delineating the fork and roller action in
any desired position, it must be remembered that the points of location
of the real impulse radius, the end of horn, the dart or guard pin and
crescent, must _all_ be obtained _when standing against the bank_, and
the arcs drawn which they describe; the parts are then located according
to the angle at which they are removed from the banks.

We think the instructions given are ample to enable any one to master
the subject. We may add that when one becomes well acquainted with the
escapement, many of the angles radiating from a common center, may be
drawn in at once. We had intended describing the mechanical construction
of the escapement, which does unmistakably present some difficulties on
account of the small dimensions of the parts, but nevertheless it can be
mechanically executed true to the principles enumerated. We have evolved
a method of so producing them that young men in a comparatively short
period have made them from their drafts (without automatic machinery)
that their watches start off when run down the moment the crown is
touched. Perhaps later on we will write up the subject. It is our
intention of doing so, as we make use of such explanations in our
regular work.
