Now, to attain this end, so desirable if Trade were to be placated, it was necessary to define with precision either whom the gang might take, or whom it might not take; and here Admiralty, though notoriously a body without a brain, achieved a stroke of genius, for it brought down both birds with a single stone. Postulating first of all the old _lex sine lege_ fiction that every native-born Briton and every British male subject born abroad was legally pressable, it laid it down as a logical sequence that no man, whatever his vocation or station in life, was lawfully exempt; that exemption was in consequence an official indulgence and not a right; and that apart from such indulgence every man, unless idiotic, blind, lame, maimed or otherwise physically unfit, was not only liable to be pressed, but could be legally pressed for the king's service at sea. [Footnote: _Admiralty Records_ 7. 300--Law Officers' Opinions, 1778-83, No. 26; and _Admiralty Records_ 1. 581--Admiral Berkeley, 14 Feb. 1805, well express the official view.] Having thus cleared the ground root and branch, Admiralty magnanimously proceeded to frame a category of persons whom, as an act of grace and a concession to Trade, it was willing to protect from assault and capture by its emissary the press-gang. These exemptions from the wholesale incidence of the impress were not granted all at once. Embodied from time to time in Acts of Parliament and so-called acts of official grace--slowly and painfully wrung from a reluctant Admiralty by the persistent demands and ever-growing power of Trade--they spread themselves over the entire century of struggle for the mastery of the sea, from which they were a reaction, and, touching the lives of the common people in a hundred and one intimate points and interests, culminated at length in the abolition of that most odious system of oppression from which they had sprung, and in a charter of liberties before which the famous charter of King John sinks into insignificance.
