renders it both incomingdions and dange- 
Pous, and even inadequate to its purpole; 
and ‘alfo dhe which, if diflerently placed, 
might be“rédticed* to one half, or even 
one-fourth part of its preient dimentions, 
with increaled eifeét, its power being not 
only. greater .by projecting into more 
active, water, and meeting the current in 
its undiverted courte, but alfo inereafed 
by its relative diftance from, the’ centre 
line’ of the veifel’s progrefs. ., J 
The manner of working a helm of this 
defeription muft depend on the nature, 
fize, and fervice of the veflel. It may act 
outwards or either way, be without or in- 
clofed within the ftern and fide, above or 
could not only f 
below the deck, and moved by one. gue 
winch or other engine, placed amid thips | 
or elfewhere, and conneéted by chains or 
ropes, Ink the ordinary way, with a fhort 
iron lever, projecting from each radder, 
the length of which need not exeeed the 
fixth part of the tiller required for the 
common rudder. ‘In this manner,” 
fays Mr. N. “TI found by an experiment 
tried on a temporary form, of not lefs 
than one hundred and fifty tons burthen, 
confiructed by me for the purpofe about ~

this. {pecification, we have a reprefenta- 
tion of the tranfverfe fection of a veflel,

and extending down to’ a level with the 
under part of her keel, oppofing by their 
extent and fhape the ‘greateft refiftance, 
to a lee courfe with lefs tendency to roll 
or.upfet, and prefenting at the fame time 
a fironger furface to the preffure of the 
_ CAargO: er: weight within the fhip. Re- 
fittance to leeway may alfo, we are told, 
be increafed, by ribbing, or indenting the 
coat ot the fide, with projecting orbinding 
planks, that obftruct in a fide direétion, - 
only while they ftrengthen the veffel and 
prote eét the caulking. For farther infor- 
ation on this fubject, we mutt refer the 
reader to the eh age itfelf, the forms
