instructions as to whether the carriage
shall be shipped by water or railroad If
by railroad it must be taken apart and
the h'>l-platc set sideways on the car. in
which Il place must be cut for it to rest
in and to allow it to pass under the
bridges. Another carriage under way is
12-inch one for a gun lift, which is Il
duplicate of one built at the works of
LIE Creusot in France.
This carriage is substantially a bar
bette carriage, but with increased length
