GEMS AND JEWELS. 
The collection of gems and precious stones that, during the 
World’s Columbian Exposition, attracted so much attention at 
the Tiffany pavilion in the Manufactures Building, and in the 
gallery of the Mines and Mining Building, occupies the central 
cases in this hall. It is believed to be the most complete col-
