ton-mile

Were the added cost of each ton mile as great as before, the operating expenses would rise by the full ten per cent.

Even this latter rate by itself does not seem absolutely excessive, yielding a revenue of less than four mills per ton mile.

This is best measured, of course, by revenue per ton mile, chap.

For the latter places would necessarily be assessed at a higher rate per ton-mile.

Obviously, the ton-mile rate steadily falls within such a group with progressive remoteness.
