Apart, however, from sentimental consideration, there are many reasons why the grade of mates should be held so different. For instance, the master of one ship, however small, if only he be gentlemanly and accustomed to command, will find little or no difficulty in springing suddenly to the command of another ship, no matter how large. Because the minor details are attended to by his subordinates, who are usually competent men, and he, being at the head of the position, can calmly observe matters without letting any one see that he is strange to such a giddy height. Not so the mate. If it were possible to transfer, say, a mate of a schooner into the position of mate of a three-thousand-ton sailing ship without much previous training, he would be lost. His new duties would overwhelm him. As well expect a small tradesman, who has been grubbing away in a little suburban shop on a turnover of £4 a week, to suddenly assume charge of one of the largest departments at Whiteley's, or the Army and Navy Stores. For the mate does not merely command the ship during the master's absence, or act as the master's mouthpiece: it is his to see that orders given are carried out, and to hold the proper person responsible for neglect. But perhaps we are getting along too fast. To return, then, for a moment to a consideration of how the mate attains his position, that last rung but one on the ladder of promotion, which, alas! is separated by so wide a gulf from the next one above. It is hardly necessary to go over again the various steps which have been already mentioned in the case of the master, except in the most cursory manner: First, usually, but not compulsorily, the serving of a term of apprenticeship fixed at four years by law, the last year of which is counted as the service of able seaman. Or, as the rules merely specify that the candidate for a second mate's certificate shall have been four years at sea, one year of which he was an able seaman, he may have simply entered as boy and gone on to ordinary seaman, and then to A.B. This course is the one adopted in American and Canadian ships, where apprenticeships are unknown; but there the candidate is usually in far better case than any apprentice in a British ship, because he is sure to be put on board by some one whom the master is anxious to please, or, more probably, he is a friend or relative of one of the officers themselves; in which case, although his designation may be humble enough, he will live in the cabin, and have his profession thoroughly burnt into him--a process which he will in nowise be able to escape.
