III. (p. 052)

If Steam is employed between Falmouth and Fayal, and in all the West

Indian department, and supposing that all the remainder of the general

plan for the western world is performed by sailing packets, then the

results will be:--

Capital required by new plan this way £335,500

Ditto employed under the present system 392,500

--------

Difference LESS £57,000

--------

Yearly cost by present system £184,000

Ditto by new plan 168,500

--------

Difference LESS £15,500

But to this difference ought to be added the

sum of 6885_l._ saved in coals by using sails,

and the sum of 7600_l._ allowed in new plan

but not taken into account in the present,

for the expense of coal depôts, and places

for repairs, 7600_l._ together 14,485

--------

True difference LESS £29,985
