Answer:
To ensure that Kansas voted to become a free state.
Explanation:
Free-soilers are people who do not exactly disapprove of slavery as itself, but they do disapprove of expansion of slavery westward. In the 1800s, territories such as Kansas and other frontiers needed population to be able to join the United States, and to vote whether or not they join as a slave or free state. Both sides, wanting to gain the upper-hand in legislative voting, had people move into Kansas in hopes of voting Kansas to joining either/or as a free/slave state.
In the case of the free-soilers, therefore, based on their definition, they would want Kansas to join as a free state.
