galleys of this description would hnve done all that has been done 

 at a twentieth of the cost, and perhaps 'ere this, have opened a 

 regular and steady trade with the tribes in the interior. 



The second boat is building for an emigrant ship (figs. 5 to 8). 

 She is in four sections, and can be used as an ordinary boat of 

 26 feet long (figs. 7 and 10), as a barge 38 feet, or a galley of 50 feet 

 (fig. 5), at which size she would carry in safety 150 people. 



Eire is the great danger to be apprehended on board emigrant 

 vessels. In an hour after a fire was discovered these boats could 

 be joined and towing astern, and the awful scenes that took place 

 on board the Ocean Monarch and Caleb Grimxhaw avoided. 



All naval officers who have served on the coast of Africa, and 

 the Indian Seas, know the advantages of having large and fast 

 boats. On this sectional plan, a boat 60 feet long can be stowed 



in a length of 25 feet on the booms, and be put together in a few 

 minutes by her crew, when her services are required to chase in 

 calms or baffling winds, or to land troops; or, fitted as a tender, 

 slie could be sent to cruise with a month s provisions and water on 

 board; a simple and cheap way of doubling the efficiencv of a 

 blockading squadi-on. Droghers, lighters, and small craft'of all 

 sorts and sizes, can be sent out to all parts of the world, at the 

 lowest rate of freight, and put together with the greatest facility 

 and accuracy, without the aid of mechanics or skilled labourers. 



I may add, that I propose making all boats for passenger-vessels 

 life-boats, by using Light's prepared rushes, which are much 

 superior to any system of air-chambers, and securing them from 

 oxidation hy__galvanising the plates, which also saves the expense 

 of painting."
