United States Exploring Expedition
In one very important way, the work of the United States Exploring Expedition was only beginning when the ships returned to Washington after almost four years at sea. In addition to Captain Wilkes himself who recorded ocean and weather data and surveyed island groups and coastlines, the Expedition had carried a civilian group of scientists who had collected specimens, artifacts, and observations through the whole voyage. Called the "scientific corps," or just the "scientifics," they were Horatio Hale, ethnographer & linguist; Charles Pickering and Titian R. Peale, naturalists; J.P. Couthouy, conchologist; James D. Dana, mineralogist; William Rich and William D. Brackenridge, botanists; and Alfred T. Agate and Joseph Drayton, artists.
