4 Mr. Seppings on the great strength given to 
“ on the upper deck, one foot two inches and five eighths ; 
“ and at the expiration of twenty-four hours she had hogged 
“ or further broke her sheer two inches and five-eighths, 
“ and then appeared stationary, and completely borne by the 
“ trusses. 
“We then proceeded to take away the trusses in the 
“ hold, and when they were wholly disengaged, she further 
“ hogged, or broke her sheer, six inches. We next pro- 
“ ceeded to take away the trusses in the ports, and when 
“ they were wholly cleared, she dropped at the extremities, 
“ (or further hogged) three inches and a half, and was in 
“ the same position when tried twenty-four hours after. 
“We further beg leave to state, that the whole of the 
“ trusses marked B, slackened as the ship floated from the 
“ blocks, and became short from half an inch to three inches 
“ and a half, and partook of no part of the pressure ; which in 
“ our opinion clearly proves that the direction in which Mr. 
“ Seppings has applied his diagonal frame is correct, as also 
“ the great utility of the trussing system ; for although this 
“ ship, from her very defective state, was much against so 
“ severe an experiment, it has proved to us its good effects 
“ most satisfactorily ; for many of the trusses in the ports 
“ forced the timbers three eighths of an inch within the ends 
“ of their covering planks, thereby lessening their effect from 
“ what it would have been if the ship had been of a sounder 
“ texture ; yet on a ship in this state, the trussing between 
“ the ports alone, after those in the hold were wholly disen- 
“ gaged, had the effect of sustaining the immense pressure 
“ of both ends of the ship in her worst position, and pre- 
“ vented her from breaking, which she otherwise would
