Answer: Steamboat
Explanation:
Captain Lund used the steamboat as a form of transportation in the mid 1800's. Steamboats were used to transport cargo and people during that time. Steamboats were also essential for the mail to get delivered to places all over the country since transportation was limited. New settlers depended on the steamboat not only for passage to their new homes but for the mail to be delivered to them. Mail could take months to reach a home or business in those days.
