The "Treasure Room" was originally constructed in Walter Library to Mr. Bell's specifications. He wrote in his diary, "I am not at all in sympathy with the monotonous type of panelling which he [the University's architect] has incorporated in his sketches." Mr. Bell subsequently purchased panelling hand carved in the early 20th century with the other furnishings--all period antiques--from French and Company, New York.
