I have recently relocated my twainsgeography site to Amazon's cloud
server and am combing through my site for bothersome details. For those
interested in such minutia, Fears' Day by Day contains this passage:
"The pair set off with an old guide and climbed on foot up through the
pass, coming down a precipitous trail to the village of*Leuk***(a short
distance from*Leukerbad*)[Rodney 106]."
Fears apparently got this from Robert Rodney's "Mark Twain Overseas".
The order of villages is actually reversed. Leukerbad is the village
with the baths and is found at the base of Gemmi Pass. Leuk is the town
to the south of Leukerbad.
Just thought I'd mention it...
