CHAPTER II. MEN OF PEACE. Naval Life in Peace Times—A Grand Exploring Voyage—The Cruise of the _Challenger_—Its Work—Deep-sea Soundings—Five Miles Down—Apparatus Employed—Ocean Treasures—A Gigantic Sea-monster—Tristan d’Acunha—A Discovery Interesting to the Discovered—The Two Crusoes—The Inaccessible Island—Solitary Life—The Sea-cart—Swimming Pigs—Rescued at Last—The Real Crusoe Island to Let—Down South—The Land of Desolation—Kerguelen—The Sealers’ Dreary Life—In the Antarctic—Among the Icebergs. No form of life presents greater contrasts than that of the sailor. Storm and calm alternate; to-day in the thick of the fight—battling man or the elements—to-morrow we find him tranquilly pursuing some peaceful scheme of discovery or exploration, or calmly cruising from one station to another, protecting by moral influence alone the interests of his country. His deeds may be none the less heroic because his conquests are peaceful, and because Neptune rather than Mars is challenged to cede his treasures. Anson, Cook, and Vancouver, Parry, Franklin, M’Clintock, and M’Clure, among a host of others, stand worthily by the side of our fighting sailors, because made of the same stuff. Let us also, then, for a time, leave behind the smoke and din, the glories and horrors of war, and cool our fevered imaginations by descending, in spirit at least, to the depths of the great sea. The records of the famous voyage of the _Challenger_(24) will afford a capital opportunity of contrasting the deeds of the men of peace with those of men of war.
