This significant [decline in Carolina's Indian slave population] had begun well before the Yamasee War and was accompanied by a decline in the cash value of Indian slaves. In 1722 (when Negro slaves were worth several hundred pounds in Carolina currency), the government offered Col. Theophilus Hastings L50 for each remaining Yamasee he could take, dead or alive. It was added that "in Case he Engages the Creeks or any other Indians utterly to destroy the Said nation of Yamasees the Said Hastings for such Extraordinary Service shall be paid out of the Publick Treasury of the Province the Sum of One Thousand pounds." (Hastings returned with five scalps and three captive Indians, two of whom were set aside by Gov. Nicholson as gifts for the Prince and Princess of Wales.)
