Canada's mineral showing was so ponderous as to exceed the weight of 125
tons. It comprised every known species of mineral, marble, and granite in
that country. In this enormous collection we discovered a block of pure
nickel weighing 4,600 pounds as well as very large nuggets of native gold
and silver. Mexico made its most extensive contributions to this
departmental structure. Brazil, the Argentine Republic, Russia, Spain,
Greece, Italy, Japan, Belgium, Austria, Ecuador, and other foreign nations
were likewise well represented.
The most prominent exhibits were grouped in the eastern section of the
ground floor. They proved the unexcelled mineral wealth of the United
States, particularly in iron, the annual production exceeding 10,000,000
tons.
Pennsylvania took the leading place being pre-eminent in her iron and
steel industries. Her supremacy in the production of "black diamonds" was
manifested by a rich display; one trophy from her immense coal-mines was a
shaft of coal sixty-two feet high, and ten feet square. Colorado's fine
exhibit of precious metals had, as an appropriate frame, a beautiful
pavilion erected entirely from her local products. The abundance of gold
in this important mining state is evinced by the fact that twenty-one of
her thirty-three counties are producing that most desirable and malleable
of all metals.
