Apprentices fell into a double category--those bound to the sea, those apprenticed on land. Nominally, the sea apprentice was protected from the impress for a term of three years from the date of his indentures, provided he had not used the sea before; [Footnote: 2 & 3 Anne, cap. 6, re-affirmed 13 George II. cap. 17.] while the land apprentice enjoyed immunity under the minimum age-limit of eighteen years. The proviso in the first case, however, left open a loop-hole the impress officer was never slow to take advantage of; and the minimum age-limit, as we have just seen, had little if any existence in fact. Apprentices pressed after the three years' exemption had expired were never given up, nor could their masters successfully claim them in law. They dropped like ripe fruit into the lap of Admiralty. On the other hand, apprentices pressed within the three years' exemption period were generally discharged, for if they were not, they could be freed by a writ of Habeas Corpus, or else the masters could maintain an action for damages against the Admiralty. [Footnote: _Admiralty Records_ 7. 300--Law Officers' Opinions, 1778-83, No. 25.] 'Prentices who "eloped" or ran away from their masters, and then entered voluntarily, could not be reclaimed by any known process at law if they were over eighteen years of age. On the whole, the position of the apprentice, whether by land or sea, was highly anomalous and uncertain. Often taken by the gang in the hurry of visiting a ship, or in the scurry of a hot press on shore, he was in effect the shuttlecock of the service, to-day singing merrily at his capstan or bench, to-morrow bewailing his hard fate on board a man-o'-war. When it came to the exemption of seamen, Admiralty found itself on the horns of a dilemma. Both the Navy and the merchant service depended in a very large degree upon the seaman who knew the ropes--who could take his turn at the wheel, scud aloft without going through the lubber-hole, and act promptly and sailorly in emergency. To take wholesale such men as these, while it would enormously enhance the effectiveness of His Majesty's ships of war, must inevitably cripple sea-borne trade. It was therefore necessary, for the well-being of both services, to discover the golden mean. According to statute law [Footnote: 13 George II. cap. 17.] every person using the sea, of what age soever he might be, was exempt from the impress for two years from the time of his first making the venture. The concession did not greatly improve the situation from a trade point of view. It merely touched the fringe of the problem, and Trade was insistent.
