Answer:
Red
Step-by-step explanation:
Anthony Glass was a explorer, originally from Pennsylvania, who moved to Louisiana soon after the Revolutionary War. In 1808-09, Glass led a group of traders up the Red River in order to trade with the Taovaya-Wichita people along the river. The group stayed in the region and traded with the natives for three months. Glass's journal survives, and it tells the account of the expedition.
