The pavilion is ornamented with relief sculptures in each corner by Bela Lyon Pratt (1867–1917). The sculptures represent Spring (“Plant,”) Summer (“Bloom,”) Autumn (“Seed,”) and Winter (“Decay”.) Murals by the artist George Willoughby Maynard (1878–1934) ornament the walls and ceiling. 

In the domed ceiling, the artist has depicted the four stages in the development of a nation: Courage, Valor, Fortitude, and Achievement. Each relates to a corresponding wall mural representing the historical sequence: Adventure, Discovery, Conquest, and Civilization.  In this sequence, Adventure leads to Discovery, which in turn results in Conquest, and finally Civilization.
