For those concerned with The Long Trip through The Holy Land I have run 
into a puzzle, where exactly is Jonesborough.  Day By Day has it at Kefr 
Hauer and Strathcarron has it at Quneitra.

The pilgrims departed Damascus and reached the point where Saul saw the 
light, Al Kiswah.  From here Twain says only that they camped that night 
at Jonesborough.

"After nightfall we reached our tents, just outside of the nasty Arab 
village of Jonesborough. Of course the real name of the place is El 
something or other, but the boys still refuse to recognize the Arab 
names or try to pronounce them."

The Kefr Hauer route seems the most expedient but the Quneitra provides 
the best reason for having to avoid El Yuba Dam.

"We left Jonesborough very early in the morning, and rode forever and 
forever and forever, it seemed to me, over parched deserts and rocky 
hills, hungry, and with no water to drink. We had drained the goat-skins 
dry in a little while. At noon we halted before the wretched Arab town 
of El Yuba Dam, perched on the side of a mountain, but the dragoman said 
if we applied there for water we would be attacked by the whole tribe, 
for they did not love Christians. "
