This horribly fatal resul. will be entirely avoided in
the iron car in consequence Of the facts already given.
as also Of the superior strength where the oor aud

Another advantage Of some Importance connected
with thi, invention is The facility OF constructing cars
in various curved, and other ornamental ana tssty
forms The cultivation Of art in this respect is smst

importance than the points before presented.
Judged by few experiments on the nveted strips.
