A gentleman, who knew most of the passengers on board--and we give an authorized list of the names in the Appendix--when he heard of the catastrophe, remarked, that it would throw half Melbourne into mourning. Doubtless it will, and into how many other places besides will not the news of the catastrophe carry mourning? That one poor Bavarian, those two hapless Danes, had they no friends in the world to shed a tear over their watery grave? We dare not forget that each one, as he embarked, carried within him, as it were, a very world of varied interest, and that the hopes and sympathies of the unknown and poor were as precious and beautiful to those who knew and loved them, as were the plans and fortunes of the well-known and wealthy to the circle of which they formed part. Every death we see recorded should bring before us, in imagination, a bier, around which we see gathering a collection of mourners, refusing to be comforted, because their loved one is not. When we hear of a multitude of persons perishing in some dread calamity like the present, we must remember that, while all died together, each died alone, and will be mourned as if he alone had died. More than two hundred individual worlds of thought and feeling, of sympathy and design, went down beneath the ocean wave on that wild stormy afternoon. Each of these worlds was perhaps the very sun of other worlds, that will now receive a sudden and awful shock. Many men, many poor men even, so live that they are centres of operations which, although not brilliant in the world’s estimation, are of the deepest possible interest to all concerned in them, and when they die, it is as if the sun had been removed out of its place. Nor do we forget, as we take up the list of passengers who went out in the _London_, that every one had a separate and solemn history. We do not forget that the issues of life were unspeakably important, not only to all, but, in a very solemn manner, to each--to the poor Danish sailor as well as to the Oxford scholar: we do not forget that to each one on board, this question was proposed amid circumstances most appalling, “What shall it profit a man if he gain the whole world and lose his own soul, or what shall a man give in exchange for his soul?” We dare not forget the infinite value of every soul on board.
