The dimensions of the largest steamers vary
between 205 and 244 feet in length, and 25 and 26 feet in width. They
are 10 feet in depth, and, when empty, displace from 440 to 460 tons.
The Austrian government has two monitors repaired from time to time in
the yards of the company. The short and wide forms of these impose a
heavier load per running foot upon the ways than ordinary boats do, but
nevertheless no difficulty has ever been experienced, either in hauling
them out or putting them back into the water.--_Le Genie Civil_.

IMPROVED HIGH-SPEED ENGINE.
This engine, exhibited at South Kensington by Fielding and Platt, of
Gloucester, consists virtually of a universal joint connecting two
shafts whose axes form an obtuse angle of about 157 degrees. It has four
cylinders, two being mounted on a chair coupling on each shaft. The word
cylinder is used in a conventional sense only, since the cavities acting
as such are circular, whose axes, instead of being straight lines, are
arcs of circles struck from the center at which the axes of the shafts
would, if continued, intersect.
