Skill in seamanship, from the use of the marlinespike and the sail-needle up to the full equipping of a ship and the handling of her under canvas, was in either service the prime essential.

In both alike, cannon and small arms were carried; and the ship's company, in the peaceful trader as well as in the ship of war, expected to repel force with force, when meeting upon equal terms.

With a reduced number of naval vessels in commission, and their quarter-decks consequently over-crowded with young officers, a youth was more likely to find on board them a life of untasked idleness than a call to professional occupation and improvement.

Nelson therefore was sent by his careful guardian to a merchant-ship trading to the West Indies, to learn upon her, as a foremast hand, the elements of his profession, under conditions which, from the comparative fewness of the crew and the activity of the life, would tend to develop his powers most rapidly.
In this vessel he imbibed, along with nautical knowledge, the prejudice which has usually existed, more or less, in the merchant marine against the naval service, due probably to the more rigorous exactions and longer terms of enlistment in the latter, although the life in other respects is one of less hardship; but in Nelson's day the feeling had been intensified by the practice of impressment, and by the severe, almost brutal discipline that obtained on board some ships of war, through the arbitrary use of their powers by captains, then insufficiently controlled by law.

In this cruise he seems to have spent a little over a year; a time, however, that was not lost to him for the accomplishment of the period of service technically required to qualify as a lieutenant, his name continuing throughout on the books of the "Triumph," to which he returned in July, 1772.
Suckling's care next insured for him a continuance of active, semi-detached duty, in the boats of the "Triumph,"-- an employment very different from, and more responsible than, that in which he had recently been occupied, and particularly calculated to develop in so apt a nature the fearlessness of responsibility, both professional and personal, that was among the most prominent features of Nelson's character.
