Mrs. Paroo likes Harold and tries to find out why Marian is not interested . Marian describes her ideal man ("My White Knight"). She tries to give Mayor Shinn evidence against Harold that she found in the Indiana State Educational Journal, but they are interrupted by the arrival of the Wells Fargo wagon, which delivers the band instruments ("The Wells Fargo Wagon").

He explains that this is what he calls "The Think System", and he arranges to call on Marian to discuss it . The town ladies ask Marian to join their dance committee, since she was "so dear dancing the Shipoopi" with Professor Hill ("Pick - a-Little, Talk - a-Little" (Reprise)). They have reversed their opinions about her books, and they eagerly tell her that "the Professor told us to read those books, and we simply adored them all!" </P> <P> That night, the school board tries to collect Harold's credentials again, but he gets them to sing again and slips away ("Lida Rose").

They agree to meet at the footbridge, where Marian tells him the difference he's made in her life ("Till There Was You"). Marcellus interrupts and tells Harold that the uniforms have arrived . He urges Harold to take the money and run, but Harold refuses to leave, insisting, "I've come up through the ranks...and I'm not resigning without my commission".
