sive piece of mechanism derives it's
power from a weight of over 800
pounds, and by a simple change Of
motion, is made to revolve the light
or strike the fog bell at the intervals
required. The clock-work exhibited
is intended to strike first, three times,
then twice, then once, and so on. This
is the signal adopted. for one of the
shoals ON Long Island, to which the
light house now on the grounds is to
be removed after the Exhibition.
Near this new attraction is the fog.
syren, whose very unsyrenlike roar
has so often startled visitors to the
Exhibition. This ear'splitting in
strument is little more than very
much elongated horn blown by steam,
and yet it has been heard at dis
tance of S5 miles. The fog-horn is
located short distance from the Ohio
State Building, and some smart wag
has remarked that this is very appro-
pirate. AS it requires the use of fresh
water to generate its tremendous lung
power it can only be used at inland
points, but even when placed some
distance from the headland it has
been found very effective.
Agricultural Hall, which has been
the most backward of the large build
ings, presents an infinite variety of

interested in agricultural matters or
machinery. Within the past few
days the machinery has been put in
motion to a great extent, and visitors
can now see the manner in which
they work. More especially is this
the case with the many different
makes of mowers and reapers. Some
of these latter machines are remarka-
BILE specimens of workmanship, and
afford fine study for those who de-
light in mechanics to follow out the
apparently complex working of the
various parts which have in some
cases taken years to elaborate and
bring to their present state of perfec-
ton. The plough, also, which we
may call the initial machine in agri-
culture also shows the immense
strides that have been made within
the past thirty years. On one hand is
the huge, clumsy machine said to
have been used by Daniel Webster,
and along side of it the beautiful
finished gang plough, with all its aims
Rock and Stump Extractor, very
simple yet extremely powerful ma
chine, less known on western prairies
than in the rugged timber growing
sections. AS showing the immense
multiplications of power as applied to
mechanics it may be stated that
twenty pounds on the end of the lever
by which this machine.is operated rep
resents ton. SO light and simple is
this machine that boy of eighteen
can set it up, carry it from stump to
stump and pull out any rock that
four men can remove, place it on the
stoneboat and take it off without lift
ing or digging in fnm five tn tiftnnn
minutes. In the Olden time stumps
were a serious obstruction to cultiva-
ton of new ground and could only be
removed by patient and long-con-
itnued labor or blasted out with
powder.
Among the numerous routes by
which Centennial travel reaches this
city little attention has been paid to
those by sea, which are coming to
fo;m an important item in the arrivals
of visitors form the seaboard cities of
the Atlantic coast from Maine to
Florida The visitors come and
bring with them their provisions,
home and servants: they charter
steamers for round trip, embracing
state-rooms, fare and board Several
of these have already, chiefly from
the Eastern States, and remain week
or more in dock at the wharves, where
their passengers repair to,heir lodgings
and for their meals. The steamer
Empire State, formerly of the Boston
and New York line of steamship,
newly dubbed the Floating Palace
Hotel, is ow in port, on her first of "a
series of trips from Providence R. l.
bringing with her full complement
of passengers. She is to make these
trips in ten days, six here and four in
coming and going for which $40 is
charged including three meals per
day.
