N “ AUTOMATIC flagman” for
railway grade crossings— an ap­
paratus that in addition to ringing
a loud gong at the approach of a train,
waives u red disk by day and a red light
by night— has been devised. It is oper­
ated by a small motor, which receives
its energy from storage batteries, light­
ing circuits or trolley circuits.
On
steam roads the track is insulated and
bonded for the desired distance away
from the signal and is charged with
current from a small battery. The train
on entering the block completes the cir­
cuit and operates a relay which con­
nects the motor with the power circuit.
When the train leaves the block the cir­
cuit is opened and the motor discon­
nected. Several Imndred of the “ flag­

Coal driven and oil driven ships are

Chicago are both propelled and steered
through the crowded Chicago river by

Chinese Wheelbarrow Hauls Load. *
A barrow with a wheel as big as that
used on a wagon is used in some parte
of China, and loads o f considerable
weight are hauled upon it. The box of
bed of the barrow is divided, so that tho
wheel occupies tho central space, tho
load being piled or fastened on either
side. Such well balanced loads as that
shown in tho illustration aro not uncom­

Street Farrier.
On the streets of Paris is seen a port­

business during the winter. The farrier
takes his tools with him on his tours
through the streets, and finds his cus­

Fire Engine as Heater.
When the regular heating plant of a
Mississippi railway station was put out
of- commission by reason of damage to
the boiler, an old fire engine was cou­
pled to the heating coils of the station,
and a comfortable temperature main­
tained without difficulty. Pipes were
run from the boiler of the fire engine
to the mains in the basement o f the
station and steam was sent to all radi­
ators until the regular boiler was in
commission again.
