the center of the storm eddy advanced nearer and nearer from the southwest until the wind reached the conditions of a hurricane; that the wind between Boston and Philadelphia shifted its direction so as to come from the southwest after the center of the storm eddy had passed over this region; and that the force of the wind gradually decreased as the center of attraction—which always is the storm center—passed farther and farther away to the northeast. Another man whose name is dear to the heart of every patriotic American conducted, in conjunction with a friend, a series of weather observations, beginning in 1771 and continued during the stirring times of the Revolution. This was the sage of Monticello, Thomas Jefferson. During the first half of the nineteenth century, nearly a hundred years after Franklin’s northeast rainstorm, Redfield, Espy, Loomis, Henry, and other American scientists laboriously gathered by mail the data of storms after their passage and demonstrated their principal motions to be such as Franklin had supposed. Professor Joseph Henry, Secretary of the Smithsonian Institution, in 1855, constructed the first daily weather map from simultaneous observations collected by telegraph. He did not publish his forecast but used his large wall map for the purpose of demonstrating the feasibility of organizing a Government weather service. If there were no other achievements to the credit of the institution founded in this country through the benevolence of the English philanthropist, James Smithson, who, by the way, never gazed upon our fair land, the work of the Smithsonian Institution in connection with practical meteorology would always give it a warm place in the hearts of those who believe the crowning achievements of science consist in giving to the world knowledge which results in the saving of human life, the amelioration of the sufferings of human beings, and the acceleration of the wheels of commerce and industry. Although American scientists were the pioneers in discovering the progressive character of storms and in demonstrating the practicability of weather services, the United States was the fourth Government to give legal autonomy to a weather service. Holland established a weather service, with telegraph reports and forecasts, in 1860; England followed with a smaller service in 1861; and France in 1863. But none of these countries has an area from which observations can be collected great enough to give such a synoptic picture of storms as is necessary in the making of forecasts of much utility. It would require an international service, embracing all the countries of Europe, to equal, in extent of the area covered and of the accuracy of its forecasts, the service of the United States, which was begun in 1870, as the result of agitation by Lapham, Henry, Abbe, Maury, and others.
