constructed for the transatlantic service
Of the Cunard Line.

The Buffalo IN. " fire department
has lately received novel fire engine
which has excited much interest in that

A new machine has been designed for
the excavation of sewer trenches. The
material in this system of excavation is
handled but once, and the operation is
continuous, line of loaded buckets
passing out and line of empty ones re-
turning to be filled at the same time.
Ordinary excavating machines require
the empty buckets to be returned over
the same line over which the full ones
are sent out, and it is claimed that for
this reason the new machine can work
more rapidly and cheaply.
The six-inch ordnance rifle which sue

inch gun is 16 $40 inches, same dis
tance, and of the ten-inch gun twenty
one inches, same distance. The twelve,
inch projectile will pierce twenty eight
inches at distance of 5000 yards. The
thirteen-inch guns, which will be pro-
vided for the battle ships, are capable OF
demolishing the heaviest armor.
