may be enemies in all else, here they are to be friends. Every ship that navigates the high seas with these charts and blank abstract logs on board may henceforth be regarded as a floating observatory, a temple of science. The instruments used by every co-operating vessel are to be compared with standards that are common to all; so that an observation that is made anywhere and in any ship may be referred to and compared with all similar observations by all other ships in all parts of the world.
But these meteorological observations which this extensive and admirable system includes will relate only to the sea. This is not enough. The plan should include the land also, and be universal. Other great interests of society are to be benefited by such extension no less than commerce and navigation have been. A series of systematic observations, directed over large districts of country, nay, over continents, to the improvement of agricultural and sanitary meteorology, would, I have no doubt, tend to the development of many interesting, important, and valuable results.
With proper encouragement, this plan of research is capable of great expansion. With the aid of the magnetic telegraph, and by establishing a properly devised system of daily weather reports by telegram, sentinels upon the weather may be so posted that we may have warning in advance of every storm that traverses the country. Holland, France, and England, have recently established such a plan of daily weather reports from certain stations. And Admiral Fitzroy, at the head of the Meteorological Department of the Board of Trade in London, informs me that already, though the plan went into operation only in the month of September, 1860, yet it is most rich with the promise of a fine harvest of practical results.
The agricultural societies of many states of America have addressed memorials to the American Congress, asking for such extension over that continent.
This plan contemplates the co-operation of all the states of Christendom, at least so far as the form, method, subjects of observations, time of making them, and the interchange of results are concerned. Great good is to come of it—shipwrecks and disasters are to be prevented by it—the public weal is to be promoted by it, the convenience of society is to be enhanced by it, the bounds of human knowledge are to be enlarged by it, and it is hoped that the friends of meteorology, and all who may find
