The map sheet # 61 Lop Nor is also missing from the copy of
Serindia sent from the Univ. of Rochester library. It is the other
important map sheet as it shows the area directly south of Lou lan and north of
Abdal. This is the key region in which the Tarim, Charklik and So-lo Ho all
enter into their deltas in swamp and dry salt lake areas. The exact location of
this area was disputed until Stein performed detailed astronomical observations
and survey. He retured here in the third expedition and we have the maps from
that report - Innermostasia.
