2los inches in thickness and is polished on one cut
face while the outer edge shows the manner OF
buiding mp plate upon plate to gain the thick
ness required. 1t is probable that such plates
are rather for defensive forts than for
floating structures. The steam hammer plant
of Woolwich for forging tho sl-ton guns for
vessels of the Infexible class is another iustra-
ton Of the same order. Road steamers and steam
rollers form another class in which England leads
America at present. The Ayeiug and Porter trac-
ton engine built at Rochester England, is yet un-
excelled. Portable engines are well built in both
countries, but are far largely used in England.
Steam plOws are also an established institution
there, which cannot he said of this country. The
English applications Of the hydraulic press are more
numerous than those of Americans. In marine en-
gnes Americans are disposed also 10 gave England
tho palm In stationary engines there are none equal
10 the Corllss and some other American engines.
