Return to Jesup Statue 

 West Corridor 



To the right or west of the Jesup statue are three halls devoted to 

 Indian collections. To reach these the visitor passes through the West 

 Corridor, which is devoted to the temporary display of recent acquisi- 

 tions or small collections of particular interest. Opening from this 

 is the West Assembly Hall, frequently used for temporary exhibitions 

 as well as meetings. 



On the landing, at the head of the stairway, is the William Demuth 

 collection of pipes and fire-making appliances from many parts of the world.
