John and William Bartram visited a series of sites along the St. Johns River in Volusia County that were later included in William Bartram's book Travels. At Indian Horse Crossing and Shell Mound, they described a place where Indians swam their horses across the river, a nearby shell mound, and what is still known on the east side of the river as the Bartram Oak. At Spalding's Upper Store, William obtained provisions and met a white trader whose companion was a young Seminole woman, daughter of the White Captain, an old Seminole chief camped nearby with part of his family in an orange grove after a hunt. At High Shelly Bluff, William collected specimens of the plant now known as Bartram's Ixea and wrote his first natural history essay about it. At Stagger Mud Lake, which he called Battle Lagoon, he gave vivid accounts of alligators, including a battle between them, a scuffle with them, their nests, and their feeding on vast numbers of migrating fish, while a pair of black bears visited his campsite at night. In another area, he described ancient Indian fields and shell mounds beside orange groves and gave a detailed account of sunfish. At an ancient burying ground, William camped near sepulchres or tumuli of the Yamasees, whom he said were slain there by the Creeks in the last decisive battle. On Hontoon Island, he recounted enduring a hurricane and also described a delightful little bluff of shells, likely the remains of a Timucua shell mound. At Beresford Plantation, he landed and stayed with Lord Beresford's caretaker, then walked three miles south to Blue Spring. John Bartram in 1766 and William in 1774 both described Blue Spring, which John called a surprising fountain and William called a vast fountain of warm or rather hot mineral water with a disagreeable smell and taste. At a bluff they called Bartram's Bluff, John and William also described the preparation and eating of cabbage palm hearts stewed with bear oil.
