SECOND CALCULATION.

$2,500,000 annually collected and paid
for sixteen years, amount to (the whole sum
paid) 40,000,000

But the surplus of $673,103 deducted,
leaves $39,326,897, the net sum applied
to sink a principal of $25,000,000, and the
interest for sixteen years, 673,103
----------
39,326,897

The annual interest of $25,000,000 at six
per cent is 1,500,000, which at simple interest
in sixteen years is 24,000,000, 24,000,000
Add the principal, 25,000,000
----------
49,000,000
Bring down 39,326,897
----------
Surplus, 9,673,103

By these calculations it is clearly demonstrated,

First, that a certain net annual revenue of two millions and a half of
dollars is s
