The friendship between Farragut and Mr. Folsom did not end with this separation. The latter survived to the end of the civil war, and was thus privileged to follow the successful and great career of the admiral to whom, while yet an unformed boy, he had thoughtfully extended a helping hand. As late as 1865 letters passed between the two, showing that both cherished warm recollections of that early association; Mr. Folsom dating his, as though careful to make the coincidence, on the anniversary of the day when he parted with his pupil in the harbor of Tunis and returned alone to the plague-stricken city. The officers of the United States squadron passed a gay winter in Messina in 1819. Farragut was not yet eighteen years of age, but his bodily development had kept pace with his mental, and he writes that he always held his own at this time in all athletic exercises. The succeeding spring and summer were again spent in routine cruising on board the Franklin, seventy-four, which had taken the place of the Washington. In the fall of 1819 the squadron was in Gibraltar; and there, "after much opposition," Farragut was appointed an acting lieutenant on board the brig Shark. This promotion, coming at so early an age, he afterward looked upon as one of the most important events of his life. "It caused me to feel that I was now associated with men, on an equality, and must act with more circumspection. When I became first lieutenant, my duties were still more important, for in truth I was really commander of the vessel, and yet I was not responsible (as such)--an anomalous position which has spoiled some of our best officers. I consider it a great advantage to obtain command young, having observed, as a general rule, that persons who come into authority late in life shrink from responsibility, and often break down under its weight." This last sentence, coming from a man of such extensive observation, and who bore in his day the responsibility of such weighty decisions, deserves most serious consideration now, when command rank is reached so very late in the United States Navy.
