"Rule 2.--But if the parties would rather fight on: then, after two
shots each, (but in no case before,) B. may explain first, and A.
apologize afterward.

"Rule 3.--If a doubt exist who gave the first offence, the decision
rests with the seconds; if they won't decide or can't agree, the
matter must proceed to two shots, or a hit, if the challenger requires
it.

"Rule 4.--When the lie direct is the first offence, the aggressor must
either beg pardon in express terms; exchange tow shots previous to
apology; or three shots followed up by explanation; or fire on till a
severe hit be received by one party or the other.

"Rule 5.--As a blow is strictly prohibited under any circumstances
among gentlemen, no verbal apology can be received for such an insult;
the alternatives therefore are: the offender handing a can to the
injured party, to be used on his own back, at the same time begging
pardon; firing on until one or both is disabled; or exchanging three
shots, and then asking pardon without the proffer of the cane.

"If swords are used, the parties engage till one is well-blooded,
disabled or disarmed; or until, after receiving a wound, and blood
being drawn, the aggressor begs pardon.

"N.B. A disarm is considered the same as a disable; the disarmer may
(strictly) break his adversary's sword; but if it be the challenger
who is disarmed, it is considered ungenerous to do so.
