As regards the Antarctic regions, Maury called upon the nations of the world to coöperate in sending an expedition there. “Ho for the South Pole” was his slogan. “It is enough for me”, he wrote, “when contemplating the vast extent of that unknown region, to know that it is a part of the surface of our planet, and to remember that _the earth was made for man_; that all knowledge is profitable; that no discoveries have conferred more honor and glory upon the age in which they were made, or been more beneficial to the world than geographical discoveries; and that never were nations so well prepared to undertake Antarctic exploration as are those that I now solicit”. Though the Civil War interfered with the carrying out of plans for the exploring of that portion of the globe, yet Maury’s name deserves to be remembered among those whose continued interest in this enterprise finally led to the conquering of the South Pole. Another contribution which Maury made was the laying down of lanes for steamers in the North Atlantic. The idea originated with R. B. Forbes of Boston, but was worked out scientifically by Maury. In the year 1855, at the instigation of a board of underwriters of New York, who paid for its cost, he published a chart illustrating what he called Ocean Lanes. To prepare this chart he studied the logs of 46,000 days of observations of the wind and weather of that part of the North Atlantic. Two tracks, or lanes, twenty miles wide, were laid down, to the more northern of which he proposed to confine the steamers westward bound, while the eastward bound vessels were to use the other, situated from one to ten degrees further south. Although the Secretary of the Navy immediately ordered the ships of the navy to observe these lanes, they were not generally adopted by the shipping of the world until about thirty-six years after they were formulated, and it was not until 1898 that all of the transatlantic steamship companies consented in a written agreement to use them. After a dispassionate investigation of the lanes, they said that they were impressed with the patience and researches that Maury must have made to have laid down such excellent paths, and they recognized that, had the highways been followed earlier, the great majority of the accidents which had befallen vessels in the North Atlantic might have been avoided.
