sist in part of the following, viz: more speed, better sailing , (having no wheel 
houses to impede her motion through the water;) a thousand tons more stowage, 
and greater safety (as the most vulnerable part of steamers is in the wheels, and 
the screw is placed beyond the reach of danger.) She is built entirely of well 
proved rolled iron. The ribs are forged to the required patterns, and the sheets 
similar to the plates of steam boilers, are secured to the ribs and frame work by 
screws and ^nuts, and are fastened together by bolts rivited when red hot, in the 
usual way of connecting iron sheets. The ship is then caulked and pitched like 
any other vessel. The holes in the ribs and plates are punched by a slow moving 
trip hammer, with a well tempered bolt or die connected with it, of the required 
size. This die seems to meet with no more resistance than from so much paste¬ 
board. In a similar .way, the metal is cut to any given pattern, by a continuous 
succession of holes. There will not be a particle of wood employed in the con¬ 
struction of the ship, except for the deck and the interior accommodations for pas¬ 
sengers. It is supposed she will be ready for sea in the course of the year 1841.
