パーカー.C.陳が作成したコンチェ=ダリヤ・クム=ダリヤ分岐点付近の略図。北のダムが壊れたことについては本文で述べた。南のダムはPl.35参照。四つの掘られた水路は徳門堡の「T」字のすぐ下の開口部のように示した。(水流を古い水路に戻そうとする仕事は最少の労働者に与えられる所から始まったが、失敗する運命にあったことは計画から明らかだ。流れを下流のわきへそらす試みは、左へ曲がっている所の方が、より成功するであろう。F.B.)。Sketch-map of the place of bifurcation between the Konche-darya and the Qum-darya drawn by Parker C. Chen. The northern dam is the one whose destruction is mentioned in the text. The southern
one is seen in Pl. 35. The four dug passages are here marked as one opening just below the letter ≫T≫ in Temenpu. (It is evident from the plan that the work of forcing the water back into the old channel
was started at a spot that afforded the least labour, but that it was doomed to fail. An attempt to divert the river lower down, where it bends to the left, would have been more successful. F. B.)
