_A_, _B_, _C_, and _D_ represent different occupations or subgroups in
the table we have before used. At one date a static adjustment called
for fifty units of labor at _A_, forty at _B_, seventy at _C_, and one
hundred at _D_. A half decade later, after improvements had taken
place at _A_, _B_, and _D_, static forces, if they were allowed to
have their full effect, would leave only forty-five men at _A_, and
thirty-five at _B_, but they would place ninety at _C_ and at _D_.
The first movements that would tend to bring this about are in the
direction indicated by the dotted lines. The transfers are made, not
by forcing men from _A_, _B_, and _D_ to _C_, but chiefly by diverting
to _C_ young laborers who would otherwise have gone to _A_, _B_, and
_D_ to replace men who are leaving in these groups.

Now, before the transfers are completed something happens that calls
for a different movement. Let us say that only three units of labor
have as yet gone from _A_ to _C_ instead of five, leaving forty-seven
at _A_; only two have gone from _B_, leaving thirty-eight; and only
five have gone from _D_, leaving ninety-five at that point. Eighty
would then be at _C_, and the static adjustment would not have been
perfectly attained. It is at this point that a new change of
conditions occurs, which calls for fifty-two units at _A_, forty-one
at _B_, sixty-five at _C_, and a hundred and two at _D_. _C_ now
contributes something to _A_ and _B_, but it gives more to _D_; and
the fluctuations go on forever. Particular men may, more often than
otherwise, stay in their places, since the incoming stream of new
labor, by going where it is needed, may suffice to make the
adjustments, in so far as they are gradually made; but labor, in the
sense of the quantum of energy embodied in a succession of generations
of men, is never at rest. It is a veritable Wandering Jew for
restlessness and in a perpetual quest of places where it can remain.
Moreover, there are to be taken into account changes so sudden that
they thrust part
