This view of the case is confirmed by subsequent events. Press warrants, identical in every respect save one with the historic warrant of 1216, continued to emanate from the Crown long after King John had gone to his account, and, what is more to the point, to emanate unchallenged. Stubbs himself, our greatest constitutional authority, repeatedly admits as much. Every crisis in the destinies of the Island Kingdom--and they were many and frequent--produced its batch of these procuratory documents, every batch its quota of pressed men. The inference is plain. The mariner was the bondsman of the sea, and to him the _Nullus liber homo capiatur_ clause of the Great Charter was never intended to apply. In his case a dead-letter from the first, it so remained throughout the entire chapter of his vicissitudes. The chief point wherein the warrants of later times differed from those of King John was this: As time went on the penalties they imposed on those who resisted the press became less and less severe. The death penalty fell into speedy disuse, if, indeed, it was ever inflicted at all. Imprisonment for a term of from one to two years, with forfeiture of goods, was held to meet all the exigencies of the case. Gradually even this modified practice underwent amelioration, until at length it dawned upon the official intelligence that a seaman who was free to respond to the summons of the boatswain's whistle constituted an infinitely more valuable physical asset than one who cursed his king and his Maker in irons. All punishment of the condign order, for contempt or resistance of the press, now went by the board, and in its stead the seaman was merely admonished in paternal fashion, as in a Proclamation of 1623, to take the king's shilling "dutifully and reverently" when it was tendered to him. In its apparent guilelessness the admonition was nevertheless woefully deceptive. Like the subdued beat of drum by which, some five years later, the seamen of London were lured to Tower Hill, there to be seized and thrown bodily into the waiting fleet, it masked under its mild exterior the old threat of coercion in a new form. The ancient pains and penalties were indeed no more; but for the back of the sailor who was so ill-advised as to defy the press there was another rod in pickle. He could now be taken forcibly.
