The methods that Marcus Whitman used to promote settlement in the Pacific Northwest include:
- He assured the settlers of peaceful relations with the Native Americans.
- He led a large group of settlers to the Pacific Northwest.
- He offered settlers a place to stop and rest at his mission.
- He published newspaper articles about the good fur trapping.
The other option, "He wrote letters to the Native American tribes asking for land," is not typically associated with Whitman's activities to promote settlement.
