I, HAVING seen and examined a draught of a frigate 

 proposed by Mr. Thompson, to be built by private 

 subscription, am of opinion that the said frigate is 

 likely to sail faster than any ship on the present con-

 to be stiff under sail, carry her guns well, and be a 

 good sea-boat. And I think that many advantages 

 will probably be derived to the public from the ex- 

 periment.
