English navigators were always busy
sailing to unknown parts, but the entire world was by no means revealed
yet. There were, particularly, big blank spaces at the bottom of the
globe. That country called by the Dutch New Holland, the eastern part
of which Cook had found - there was evidently much to be done there.
What were the southern coasts like? Was it one big island-continent, or
was it divided into two by a strait running south from the head of the
Gulf of Carpentaria? Then there was that piece of country discovered by
the Dutchman Tasman, and named Van Diemen's Land. Was it an
island, or did it join on to New Holland? There were also many islands
of the Pacific still to be explored and correctly charted, the map of
Eastern Asia was imperfect, and the whole of the coastline of
North-Western America was not accurately known.
The more Louis turned the matter over in his mind, the more he studied
his globes, maps and books of voyages, the more convinced he was that
France, as a maritime nation and a naval Power, ought to play an
important part in this grand work of unveiling to mankind the full
extent, form, nature and resources of our planet.
He sent for a man whose name the Australian reader should particularly
note, because he had much to do with three important discovery voyages
affecting our history. Charles Claret, Comte de Fleurieu, was the
principal geographer in France. He was at this time director of ports
and arsenals. He had throughout his life been a keen student of
navigation, was a practical sailor, invented a marine chronometer which
was a great improvement on clocks hitherto existing, devised a method
of applying the metric system to the construction of marine charts, and
wrote several works on his favourite subject. A large book of his on
discoveries in Papua and the Solomon Islands is still of much
importance.
As a French writer - an expert in this field of knowledge - has written
of Fleurieu, "he it was who prepared nearly all the plans for naval
operations during the war of 1778, and the instructions for the
voyages of discovery - those of Laperouse and Dentrecasteaux - for
which Louis XVI had given general directions; and to whose wise and
well-informed advice is due in large part the utility derived from
them." It was chiefly because of Fleurieu's knowledge of geography that
the King chose him to be the tutor of the Dauphin; and in 1790 he
became Minister of Marine.
Louis XVI and Fleurieu talked the subject over together; and the
latter, at the King's command, drew up a long memorandum indicating the
parts of the globe where an expedition of discovery might most
profitably apply itself.
The King decided (1785) that a voyage should be undertaken; two ships
of the navy, LA BOUSSOLE and L'ASTROLABE, were selected for the
purpose; and, on the recommendation of the Marquis de Castries - remember
Madame la Marquise!
