Yet no thought could be more unphilosophical than this. Apart altogether from divine revelation, by which we are informed that "all deeps, fire, and hail, snow, and vapour, and stormy wind," are "fulfilling God's word" (which information we are bound to receive as a matter of faith if we be Christians, and as a matter of necessity if we be men of common sense, because it is mere absurdity to suppose that the "stormy winds," etcetera, are _not_ fulfilling God's word--or will), we now know, to a great extent from practical experience and scientific investigation, that the winds blow and the waters of the ocean flow in grand, regular, uninterrupted currents. Amongst these there are numberless eddies, which, perhaps, have tended to fill our minds with the idea of irregularity and confusion; but which, nevertheless, as well as the grand currents themselves, are subject to law, and are utterly devoid of caprice. In regard to these matters there is much about which we are still in ignorance. But the investigations of late years--especially those conducted under the superintendence of Captain Maury of the American Navy, and Doctors Carpenter and Thompson of England--have shown that our atmosphere and our ocean act in accordance with a systematic arrangement, many facts regarding which have been discovered, and turned, in some cases, to practical account. See Note 1. A very interesting instance of the practical use to which scientific inquiry can be turned, even in its beginnings, is given by Maury. After telling us of the existence and nature of a current in the ocean called the Gulf Stream, he gives the following account of the manner in which upon one occasion be made use of his theoretical knowledge. In the month of December 1853, the fine steam-ship _San Francisco_ sailed from New York with a regiment of United States troops on board, bound for California by way of Cape Horn. She was overtaken, while crossing the Gulf Stream, by a gale of wind, in which she was dreadfully crippled. Her decks were swept, and, by one single blow of those terrible seas that the storms raise in the Gulf Stream, more than in any other part of the Atlantic, one hundred and seventy-nine souls, officers and soldiers, were washed overboard and drowned. The day after this disaster she was seen by one vessel, and again, the next day, December 26th, by another; but neither of them could render her any assistance. When these two vessels arrived in the United States and reported what they had seen, the most painful apprehensions were entertained by friends for the safety of those on board the steamer. Vessels were sent out to search for and relieve her. But where should these vessels go? Where should they look? An appeal was made to know what light the system of researches carried on at the National Observatory concerning winds and currents could throw upon the subject.
