The bottom of the boat to be quite flat, without a keel. The 
sides to be at right angles to the bottom. 
The framing to be of oak or beech floors, with oak or larch 
wood knees. 
The bottom deals to be of beech, with beech bilge planks 
eighteen inches up the side. 
The rest of the plank and deck to be of red pine-wood. Each 
end of the boat to be formed alike, after the scow-form, with a 
rudder at both ends, so that the boat never requires to be turn- 
ed, and the rudders so contrived as to be easily drawn up clear 
of the water. As it is found that horses, in particular those 
which are high bred, are very restive when they go on deal 
boards, it is proposed to obviate this inconvenieUcy, by covering 
the whole of the platforms and wings opposite to them, with old 
junk, which will be soft and yielding, somewhat like a common 
road. 
By this arrangement, four chaises, with their horses attached, 
or as many carriers’ carts, with their loading, can be taken upon 
the platforms at once. 
The passengers can have accommodation either in the poops 
or on the wings, as they may choose ; the entry to the poops or 
cabins being by the side. 
The depth of the boat to be 4 feet, and at the poop and en- 
gine-house, 8 feet. When the boat is fully loaded, it is thought 
she will only draw about feet water. The deck of the plat- 
forms to be placed at 2 feet 6 inches from the bottom of the 
boat, with folding down guard-boards, 18 inches deep, divided 
lengthways into two equal spaces, and folding upon a stanchion in 
the middle of the space. These guard-boards fold down upon 
the pier, when cattle or carriages are going out of the boat, and 
may be made 3 feet in depth, if this is thought an improvement. 
When cattle are carrying over, they are to be confined within 
the breadth bf thfe boat; that is, they are not to stand upon the
