Opinions as to the value of material drawn from these sources differed widely. The buss fisherman was on all hands acknowledged to be a seasoned sailor; but when it came to those employed in smaller craft, it was held that heaving at the capstan for a matter of only six or seven weeks in the year could never convert raw lads into useful seamen, even though they continued that healthful form of exercise all their lives. This was the view entertained by the masters of fishing-smacks smarting from loss of "hands." [Footnote: _Admiralty Records_ 1. 1497--Thomas Hurry, master, 3 March 1777.]
Admiralty saw things in quite another light. "What you admit," said their Lordships, expressing the counter-view, "it is our business to prevent. We will therefore take these lads, who are admittedly of no service to you save for hauling in your nets or getting your anchors, and will make of them what you, on your own showing, can never make--able seamen.": The argument, backed as it was by the strong arm of the press-gang, was unanswerable.
The fact that the fisherman passed much of his time on shore did not free him from the press any more than it freed the waterman, or the worker in keel or trow. In his main vocation he "used the sea," and that was enough. For the use of the sea was the rule and standard by which every man's liability to the press was supposed to be measured and determined.
Except in the case of masters, mates and apprentices to the sea, whose affidavits or indentures constituted their respective safeguards against the press, every person exempt from that infliction, whether by statute law or Admiralty indulgence, was required to have in his possession an official voucher setting forth the fact and ground of his exemption. This document was ironically termed his "protection."
Admiralty protections were issued under the hand of the Lord High Admiral; ordinary protections, by departments and persons who possessed either delegated or vested powers of issue. Thus each Trinity House protected its own pilots; the Customs protected whale fishermen and apprentices to the sea; impress officers protected seamen temporarily lent to ships in lieu of men taken out of them by the gangs. Some protections were issued for a limited period and lapsed when that period expired; others were of perpetual "force," unless invalidated by some irregular acton the part of the holder. No protection was good unless it bore a minute description of the person to whom it applied, and all protections had to be carried on the person and produced upon demand. Thomas Moverty was pressed out of a wherry in the Thames owing to his having changed his clothes and left his protection at home; and John Scott of Mistley, in Suffolk, was taken whilst working in his shirtsleeves, though his protection lay in the pocket of his jacket, only a few yards away.
