THE EAST COURT. 
Separated from the West Court by the Columbian Rotunda, a 
memorial of the greatest of expositions, is a series arranged to 
show human progress during four centuries. 
A plaster group, representing an Indian armed with primitive 
bow and arrow, killing the buffalo upon the prairie, stands next to 
the rotunda. 
A fine series of representative primitive boats, the earliest ap- 
pliances for inier-communication, come next, while close by is a 
gondola of the most modern type, of fine design and luxurious 
furnishing, ready for service, manned by two gondoliers in gay 
apparel. 
Next on the east is the figure of Vulcan, of hammered copper, 
and of heroic size, which stands upon a pedestal composed of sec- 
tions of iron beams artistically arranged, typifying man’s strength 
and skill in utilizing the products of the mineral kingdom. 
The modern methods of transmitting great power at high 
speeds, is represented by the immense wooden pulley, i8 feet in 
diameter, the largest of its kind, flanked by a large steel gear 
wheel. 
Full size models of the locomotives of Trevithick and Steph- 
enson, whose names will ever be associated with the invention of 
the locomotive, stand near the east door. They illustrate man s 
conquest over the elements in our century, by applying the gen- 
erated forces to inanimate matter, and complete the series.
