Breadth of the Pallets, and the Strength of the Hand- 
fpikes be proportionable. And the moving Force will 
always be in proportion to the Strength and Number 
of the Men employ’d, and not to the Number of Ma- 
chine as in the common Oars, which too are im- 
practicable in Ships above the fourth Rate, by Reafon 
of their great Length, which will be difproportionate 
to the ordinary Bulk of a Man. 
By this means the Crew will be free from the Fatigue 
of towing, and the Vellel will move incomparably 
fafler than if it was towed ; becaufethe Chaloups which 
tow, are fubject to the Inconveniencies of the common 
Way of towing, by lofing two thirds of the Time ; 
and befides, they can’t acd all together : And the Veflel 
that is towed, pulling them back after the Oar has 
made its Stroke, they have fo much of the Space to 
regain by the next Stroke. Befides, the Cable by 
which they tow, finking into the Water by its own 
Gravity, the Refidance the Water makes to its Re- 
turn, is to be overbalanced ; all which Circumdances 
together confiderably diminilh the towing Force. 
Befides, this Invention is not fuch as is dedrucdive to 
Mankind, and becomes ufelefs to the Nation that fird 
puts it in Practice, when generally known ; on the con- 
- trary, it may be greatly advantagious to the Inventors at 
the Beginning, and every where (erviceable on many Oc- 
cadons, when it is put in Practice by thofe who ufe the
