and Ports on the Great Lakes
,’ followed (for which last a vote of thanks was offered by the Illinois Legislature). These papers were received and acted on with so much enthusiasm that he was placed at the head of the ‘Depot of Charts and Instruments’ at Washington
, which office he soon extended, in the course of five years, into the world-renowed National Observatory and Hydrographic Department (which since his death has been divided up into three separate offices). While in charge of those he published for several years his ‘Astronomical Observations Cataloguing the Stars,’ and his ‘Physical Geography of the Sea
,’ by which, as Baron Humbolt
said, he founded a new science.
He also established ‘Water works and river guages for the Mississippi river
and its tributaries,’ and directed Lieutenant Mann
to make a series of daily observations for three hundred and sixty-five consecutive days on the temperature, velocity, evaporation and precipitation and amount of salt contained in its waters, which observations, reported to and digested by Maury
, contribute the main data of the knowledge we now possess of the habits of this, our greatest river.
was the originator of the plan to ‘Redeem the drowned lands on the Mississippi river
,’ of the ‘Warehousing System,’ of the ‘Great Circle Routes’ between American and European
or Asiatic ports.
The ‘Steam Lanes’ which are still used by all steamers crossing the ocean, were laid off by Maury
, and the merchants and underwriters of New York were so pleased with their success that they presented him with a service of plate and five thousand dollars.
planned the two Arctic expeditions of Dr. Kane
and De Haven
, and both those officers received their instructions from him. The same was the case with Captain Lynch
's exploration of the ‘Dead Sea
’ and Herndon
's exploration of the Amazon
and its tributaries—as a resultant of which Maury
hoped to see established intimate commercial relations with Brazil
and the South American Republic
's Inca Papers, &c.) And just as the war came on he was organizing an expedition to the South Pole.
He made many efforts to arrest the war by appeals to the governors of the border States, by peace commissions, &c., and he died while filling the post of Professor
of Physics at the Virginia Military Institute in 1873.
His last work was a ‘Preliminary Report on the Physical Survey
’ (setting forth in an attractive manner her great resources of the field, forest and mine, to induce immigrants to come and settle up her waste places).
‘In grateful recognition of the past services conferred by Maury
upon navigation and science,’ gold medals were struck in his honor
