ortunity. Meanwhile, if a
man cannot at first win entrance into the business he prefers, he has
usually one or more alternative preferences, pursuits for which he has
some degree of aptitude, although not the highest. Every one, indeed,
is expected to study his aptitudes so as to have not only a first
choice as to occupation, but a second or third, so that if, either at
the outset of his career or subsequently, owing to the progress of
invention or changes in demand, he is unable to follow his first
vocation, he can still find reasonably congenial employment. This
principle of secondary choices as to occupation is quite important in
our system. I should add, in reference to the counter-possibility of
some sudden failure of volunteers in a particular trade, or some sudden
necessity of an increased force, that the administration, while
depending on the voluntary system for filling up the trades as a rule,
holds always in reserve the power to call for special volunteers, or
draft any force needed from any quarter. Generally, however, all needs
of this sort can be met by details from the class of unskilled or
common laborers."

"How is this class of common laborers recruited?" I asked. "Surely
nobody voluntarily enters that."

"It is the grade to which all new recruits belong for the first three
years of their service. It is not till after this period, during which
he is assignable to any work at the discretion of his superiors, that
the young man is allowed to elect a special avocation. These three
years of stringent discipline none are exempt from, and very glad our
young men are to pass from this severe school into the comparative
liberty of the trades. If a man were so stupid as to have no choice as
to occupation, he would simply remain a common laborer; but such cases,
as you may suppose, are not common."

"Having once elected and entered on a trade or occupation," I remarked,
"I suppose he has to stick to it the rest of his life."

"Not necessarily," replied Dr. Leete; "while frequent and merely
capricious changes of occupation are not encouraged or even permitted,
every worker is allowed, of course, under certain regulations and in
accordance with the exigencies of the service, to volunteer for another
industry which he thinks would suit him better than his first choice.
In this case his application is received just as if he were
volunteering for the first time, and on the same terms. Not only this,
but a worker
