This power also she held alone, unshared by friend and unchecked by foe.

She alone was rich, and in her control of the sea and her extensive shipping had the sources of wealth so much in her hands that there was no present danger of a rival on the ocean.

Thus her gain of sea power and wealth was not only great but solid, being wholly in her own hands; while the gains of the other States were not merely inferior in degree, but weaker in kind, in that they depended more or less upon the good will of other peoples.
Is it meant, it may be asked, to attribute to sea power alone the greatness or wealth of any State?
Certainly not.

The due use and control of the sea is but one link in the chain of exchange by which wealth accumulates; but it is the central link, which lays under contribution other nations for the benefit of the one holding it, and which, history seems to assert, most surely of all gathers to itself riches.

In England, this control and use of the sea seems to arise naturally, from the concurrence of many circumstances; the years immediately preceding the War of the Spanish Succession had, moreover, furthered the advance of her prosperity by a series of fiscal measures, which Macaulay speaks of as "the deep and solid foundation on which was to rise the most gigantic fabric of commercial prosperity which the world had ever seen." It may be questioned, however, whether the genius of the people, inclined to and developed by trade, did not make easier the taking of such measures; whether their adoption did not at least partially spring from, as well as add to, the sea power of the nation.
