Now this is
equivalent to an addition to the actual power of the country of
one hundred and sixty-seven men, without increasing the quantity
of food consumed; and it should also be remarked, that the time
of the class of men thus supplied, is far more valuable than that
of mere labourers.
NOTES:
1. This table is extracted and reduced from one of Ravinet,
Dictionnaire Hydrographique. 2 vols. 8vo. Paris. 1824.
2. I am indebted to F. Page. Esq. of Speen, for that portion of
this table which relates to the internal navigation of England.
Those only who have themselves collected statistical details can
be aware of the expense of time and labour, of which the few
lines it contains are the result.
3. The tidal navigation includes: the Thames, from the mouth of
the Medway; the Severn, from the Holmes: the Trent, from Trent
Falls in the Humber; the Mersey from Runcorn Gap.
Chapter 35
On the Future Prospects of Manufactures, as Connected with
Science
453. In reviewing the various processes offered as
illustrations of those general principles which it has been the
main object of the present volume to support and establish, it is
impossible not to perceive that the arts and manufactures of the
country are intimately connected with the progress of the severer
sciences; and that, as we advance in the career of improvement,
every step requires, for its success, that this connection should
be rendered more intimate.
