Frank Merriwell Down South is the fifth book in the Merriwell Series. Frank first searches for a lost Silver Palace in Mexico. Then he travels to New Orleans for Mardi Gras, and at the same time, encounters the mystery of the Queen of Flowers. After that, he experiences an adventure in Florida's Everglades, encountering a white canoe that somehow paddles. If you are not yet exhausted (and Frank never tires, it seems), he encounter moonshiners in the mountains of Tennessee. "Down South," for sure!
