atings of these vessels will, however, very much mislead people as
to the real strength of the armament. The 74's and 80's are in weight
of broadside equal to most three-decked ships; the first-class frigates
are double-banked of the scantling, and carrying the complement of men
of our 74's. The sloops are equally powerful in proportion to their
ratings, most of them carrying long guns. Although flush vessels, they
are little inferior to a 36-gun frigate in scantling, and are much too
powerful far any that we have in our service, under the same
denomination of rating. All the line-of-battle ships are named after
the several states, the frigates after the principal rivers, and the
sloops of war after the towns, or _cities_, and the names are decided by
lot.

It is impossible not to be struck with the beautiful architecture in
most of these vessels. The Pennsylvania, rated 120 guns, on four decks,
carrying 140, is not by any means so perfect as some of the
line-of-battle ships.

Note. The following are the dimensions given me of the ship of the line
