The Brussels Conference was an unqualified success, and Maury was very enthusiastic over the new chapter of Marine Meteorology which was about to be opened in the volume of Nature. “Rarely before”, he wrote somewhat later, “has there been such a sublime spectacle presented to the scientific world: all nations agreeing to unite and coöperate in carrying out one system of philosophical research with regard to the sea. Though they 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”.[4]
Soon after the conference, Prussia, Spain, Sardinia, the free city of Hamburg, the republic of Bremen, Chile, Austria, and Brazil, all joined the enterprise; and the Pope established honorary flags of distinction for the ships of the papal states, which could be awarded only to those vessels which kept the abstract logs of the Brussels Conference.
Maury took with him on this mission to Europe his two eldest daughters and their cousins Ellen Herndon and Ellen Maury, who were dubbed by acclamation on the steamer the “Magpie Club”. In England the party was invited to Wrottesley Hall near Wolverhampton, by Lord Wrottesley, then President of the Royal and Astronomical Societies, with whom Maury had corresponded for several years. Before returning to America, he and his “Magpie Club” traveled in France, Holland, and Germany, and visited the great scientist Humboldt, whose “Cosmos” had greatly influenced Maury’s scientific ideas.
Back at home again, Maury took up his work with renewed energy, and with the data which came in, through the greatly increased coöperation, from all quarters and in many different languages, he revised his charts of the North and South Atlantic, and of the North and South Pacific, and then charted the Indian Ocean as well. Not only was the route to Rio definitely decreased by one fourth, but also other passages began to be shortened with the accompanying saving for all the men and commerce that used Maury’s suggested routes. The gold rush to California, which began in 1849, vastly increased the shipping from the Atlantic ports of the United States to San Francisco. Time then became a more important element in that passage than ever before, and in 1850 clipper ships were launched for this particular trade, with the object of making the voyage as short as possible. It was, therefore, a splendid opportunity for putting Maury’s charts to the test, and the practical results of his new sailing directions soon displayed themselves.
Before his charts came to be used, the average passage from New York to San Francisco was about 180 days, but by the year 1855 the average passage between those ports for the year round had been reduced to 133 days. Moreover, there were dozens of clipper ships which, under Maury’s directions, made the voyage in 110 days or even less. The record was made in 1851 by the Flying Cloud, which fairly flew over the passage in 89 days and 21 hours, during one day making the extraordinary distance of 433½ statute miles or sailing at the rate of 18 statute miles per hour. This exploit was celebrated with great rejoicing in San Francisco, because the inhabitants felt that they had been brought so much nearer to their old homes in the East.
Under the circumstances it was but natural that there should be races among the clipper ships. The route from New York to San Francisco became the great racecourse of the ocean, fifteen thousand miles in length. As Maury wrote, “Some of the most glorious trials of speed and prowess that the world ever witnessed, among ships that ‘walk the waters’, have taken place over it. Here the modern clipper ship—the noblest work that has ever come from the hands of man—has been sent, guided by the lights of science, to contend with the elements, to outstrip steam, and astonish the world”.[5] There was the great race in 1851 of the Raven, the Typhoon, and the Sea Witch, which was won by the first-mentioned in 105 days, though the year before this same ship had made the run in 97 days.
Another famous race was run during the winter of 1852–1853, and the ships which engaged in it were the Wild Pigeon, John Gilpin, Flying Fish, and Trade Wind. These ships, as were those in the former race, were all furnished with Maury’s charts. After a most interesting and exciting race, the Flying Fish won in just 92 days and 4 hours, though the John Gilpin was a close second, making the passage in 93 days and 20 hours. In commenting on these results, Maury wrote, “Here are ships sailing on different days, bound over a trackless waste of ocean for some fifteen thousand miles or more, and depending alone on the fickle winds of heaven, as they are called, to waft them along; yet, like travelers on the land bound upon the same journey, they pass and repass, fall in with and recognize each other by the way; and what, perhaps, is still more remarkable is the fact that these ships should each, throughout that great distance and under the wonderful vicissitudes of climates, winds, and currents, which they encountered, have been so skillfully navigated that, in looking back at their management, now that what is past is before me, I do not find a single occasion, except the one already mentioned, on which they could have been better handled.... Am I far wrong, therefore, when I say that the present state of our knowledge, with regard to the physical geography of the sea, has enabled the navigator to blaze his way among the winds and currents of the sea, and so mark his path that others, using his signs as finger-boards, may follow in the same track?”[6]
The degree of exactness which Maury’s knowledge of the sea had reached is best illustrated by the incident of the San Francisco. This ship, bound from New York to San Francisco with a regiment of soldiers on board, was disabled in a hurricane on the day before Christmas, 1853 while crossing the Gulf Stream about 300 miles from Sandy Hook. Her position on the following day, and the next day after that, was reported by passing vessels which were, however, unable to render her assistance. Maury was then asked by the Secretary of the Navy to calculate her position for the assistance of the two relief ships which were to be dispatched in search of the unfortunate vessel. Although three other ships, the Kilby, the Three Bells, and the Antarctic, fell in with the wreck and rescued the remainder of her passengers, after 179 men had been washed overboard, yet it is an astonishing fact that Maury had so accurately guided the two searching revenue cutters that one of them went within sight of the spot where the drifting vessel had shortly before been found.
There was still another important passage that Maury aided materially in shortening. This was the voyage from England to Australia and New Zealand. He opposed the British Admiralty route which passed near the Cape of Good Hope, and advised ships to sail 600 to 800 miles further westward and then to continue southward until they reached the prevailing strong westerly winds which drove the clippers onward at a tremendous rate. He advised them, when homeward bound, to continue in those “brave west winds” and return by way of Cape Horn. A voyage out to Australia and home again, accordingly, encircled the globe. Whereas by the old route it had taken about 120 days each way on the average, by Maury’s new route the passage for American sailings was decreased by one third and that for the British by about one fifth.
This shortening of ships’ passages amounted to a vast saving to the commerce of the world. It was estimated that the annual saving to British commerce in the Indian Ocean alone, from Maury’s charts and sailing directions, amounted to $1,000,000 at least, and the amount saved to British commerce in all seas reached the stupendous sum of $10,000,000 annually. As to the United States, it has been conservatively estimated that the saving for the outward voyage alone from her Atlantic and California ports to those of South America, Australia, China, and the East Indies amounted to $2,250,000 per annum.
