In many cases the kind of road to be constructed, the tolls to be
charged, and the amount of profit to be permitted, were laid down
in the charters. Thus new problems confronted the various
legislatures, and interesting principles of regulation were now
established. In most cases companies were allowed, on producing
their books of receipts and expenditures, to increase their tolls
until they obtained a profit of six per cent on the investment,
though in a number of cases nine per cent was permitted. When
revenues increased beyond the six per cent mark, however, the
tendency was to reduce tolls or to use the extra profit to
purchase the stock for the State, with the expectation of
ultimately abolishing tollgates entirely. The theories of state
regulation of corporations and the obligations of public
carriers, extending even to the compensation of workmen in case
of accident, were developed to a considerable degree in this
turnpike era; but, on the other hand, the principle of permitting
fair profit to corporations upon public examination of their
accounts was also recognized.
