workers. While some pay for a certain number of
trips outright (Strength through Joy authorities
estimate that last year some 60,000 trips were
given altogether free), other employers insist
that the imapecunious worker at least pay a portion 
of the price. Still other factories operate
what is known as a "pfennig fund." By general
agreement all workers and employees contribute to
a special fund odd pfennigs over the mark sum of
their weekly salaries, the accumulated money going
to pay for trips for a number of workers chosen
each year by lot. In large factories employing
over a thousand people considerable amounts are
collected in this way and it is said that the workers 
willingly make this small sacrifice to enable
their less fortunate fellows to profit from Strength
through Joy.
