Upon the rife and progrefs, and vaft Importance, of

About the year 1793, a practice got footing in.the navy 
of rating (hips at a certain; number of guns, while their 
real complement exceeded that nominal amount. This 
fyftem, though introduced without any defign of decep¬ 
tion, gave occafiorr to foreign nations toaccule us of mif- 
reprefentation ; as when we dated that a Britifh frigate of 
38 guns had taken a foreign frigate of'44, when, in fact, 
the Britilh frigate was of equal, if not fuperior, force. 
Whence this practice arofe we cannot tel!; • but it was not 
confined to us. The American (hip Prefident had 55 
guns mounted on the day of her capture, though (he was 
rated at only 44. In the Britifh navy this practice will 
no longer continue ; for it was ordered in the year 1817, 
that the rule which prevailed prior to 1793 (hall be re¬ 
vived,. and in future all his majefty’s (hips will be rated 
at the number of guns and carronades which they actu¬ 
ally carry on their decks, quarter-decks, and forecafides. 
We fincerely rejoice in this regulation; for the navy of 
England (lands upon a bafis too broad and unafiailable 
to require the aid of any little evafive tricks; (he can- 
never want them as palliations for defeat, and (he (hauld 
difdain them asblqts which tarnilh Her conquefts.
