The Trades ut WOrk-An Exponent Of the
Nations Industry.
The American Institute Fair is still attracting
crowds Of visitors, all day ana every evening, and
no one who has once visited this great national ex.
hbiton will wonder that such Is the case. Up and
down the spacious hall are arranged the utimatcs
OF the brain process of thousands of artists ana
artisans whose thoughts, combined and re-
combined, and wrought out in tangible
good, here walt for recognition. Looked at
as the exponent OF the Invention and industry OF %
great nation, the lair is wonderfully interesting as
o whOle and, viewed IN detail it would take days
OF study to get hint of all that 1t has to tell Of
art and mechanics and agriculture. The fair has
been u success this year. and, in spite OF Tammany
and the Chicago fire and the ..nasty weather. more
people have visited it than in any previous year.
Ii Is estimated that since the opening Of the eXib
tlOn, on the 18th Of september, about
THREE HUNDRED THOUSAND PERSONS
nave availed themselves Of the opportunity to see
what the American Institute Is doing. The delicious
music heard at the Rink every afternoon has some
thing to do, no doubt with tins Increase of visitors.

time hundreds of working men study the models,

one can fall to see the great advantage Of such de-
