As danger grows."
The stanza beginning "To thee belongs," etc., is simply a lyrical paraphrase of the passage in Britannia commencing "Oh first of human blessings," and of a couplet in the last part of Liberty:—
"The winds and seas are [Britain's wide domain;]
And not a sail but by permission spreads."
The couplet
"All thine shall be the subject main,
And every shore it circles thine"
is simply the echo of a couplet in the fifth part of Liberty—
"All ocean is her own, and every land
To whom her ruling thunder ocean bears."
