We have given a fair enough specimen of the twenty-four hours of a sailor's life at sea; but of course he sometimes has an easier, and sometimes a much harder life of it--depending on the kind of ship, the nature of the voyage, the state of the weather, and the character of the captain. Some sea-captains are excellent, kind-hearted men, and make the unavoidably hard duties of their crew as easy as it is possible; but others--and very many we fear--are terrible salt-water tyrants. A captain is the absolute master of all on board--his government, as we have said, is a despotism; and this ever-present sense of his will being law while afloat, too often hardens and brutalises an originally kind heart. Landsmen! do you now envy and begrudge a living to the poor blue-jackets, who risk limb and life to carry on your commerce with the uttermost ends of the earth, and who man the wooden walls that alone render Britain the invincible mistress of the world? Ladies! dear, tender-hearted ladies! do _you_ feel indifferent to the hard lot of the gallant fellows who sail the trackless ocean to supply you with silks and diamonds, with sugar and tea, and every conceivable luxury of dress and food? Be kind, we implore you, to Poor Jack, wherever you meet him, for he would shed the last drop of blood in his veins to defend you! Make every Christian allowance for his follies and his sins when ashore. Do all you can--and we think you might do much if you would--to ameliorate his physical condition, and you will improve his moral one at the same time. For ourselves, we can only say that we ever shall own Poor Jack as a messmate and a brother, and while we have a shot in the locker, he shall freely share it, God help him! INFLUENCE OF EXAMPLE.
