For each office, if no one is elected on the first vote, a second
vote shall be taken on which shall be eligible only those who won
the first two places on the first vote. If a tie arises from one or
more members' absence or abstention from voting, successive votes
may be taken, or the election may be deferred to a later meeting,
in which case the senior member, or one of the senior members chosen
by lot, shall act as Chairman Pro Tem, and he shall appoint a Clerk
Pro Tem.
