Fast of Av: Minha
The page numbers refer to the Prayer Book for Fasts edited by Isaac Leeser, originaly published in Philadelphia in 1867, and republished in London in 1965.
Minha is the same as for the Fast of Gedalia up until the end of the Torah reading. The haftara is read to the normal Shabbat tune.
After the Amida:
Kadish Titkabal, Shir Hamaalot, Kadish Le'ela and Alenu end the service.
