Twain writes in chapter 42 as if this is the first camp site upon leaving Beirut but the Quaker City Itinerary places this on September 12, breaking camp on September 13 at 6:30am.

The camping site may actually be further east. From an entry in MTDBD:

"Passed up the Valley & camped on l. side under the dews of Hermon. –first passing through a dirty Arab village & visiting the tomb of Noah, of Deluge notoriety [MTNJ 1: 417]."
