I want to know the answer to the following question:
What did Northwestern sell to raise funds for it's first building?
All the background I'm provided with is that "Another building, University Hall, was built in 1869 of the same Joliet limestone as the Chicago Water Tower, also built in 1869, one of the few buildings in the heart of Chicago to survive the Great Chicago Fire of 1871.". Is that enough to answer the question?
