Table 16 gives the main items of the approximate expenditure. These
include all expenses for preliminary location, engineering,
superintendence, purchase of lands, water rights, etc., but do not include
other heavy expenditures chargeable to the concession, such, for example,
as general expenses, interest at the rate of 6% during the construction
period, preliminary expenses for investigations, etc., items which would
increase the total by nearly 25 per cent.
