Canada Has Equipped One of Her
TcSSclS zcifh II.

The Canadian Government has recently
equipped one OF its vessels-the steamer Eureka.
plying on inland waters-with a ship brake" says
The Scientific American" Is the name indi-
Gates the brake is intended TO check the speed
OF vessel. lt also be utilized to assist In
turning about IA limited shipwsy. During
recent trial made IN the St Lawrence River near
Montreal che steamer was driven ahead an
indicated speed OF eleven knots an hour Steam
vas then shut on. and. simultaneously the brake
Cn each side opened The vessel came 20 a fun
stop within distance equal 70 her own length
The brakes were then closed. the vessel sent
ahead until the original rate OF speed was at
tanned. when the engines were reversed and the
brakes opened. with the result that ali headway
ceased after she had gone but fifty feet-about
haf her length. In msnPuvring the Eureka AZ
fun speed. she was turned also within her own
length, with one brake thrown open. An exami-
nation 81 the hull and brake mechanism after the
tests showed apparently harmful strain or
otner damage and IN operating the brake no 5ar
o. vibration was observable by those board.
This new form OF brake is placed on the sides

attachment 20 the ship resembles somewhat an

pockets and compress the water that is contained
within the covered ways
AT ths rear end % these wavs IS a number OF

The method ~ operation is as Follows. When IL is
desired stop the vessel suddenly. IN the event
of n collision when making a landing the
catches that hold the forward ends OF the gate
are released. and by means OF the bevel the
