Travelers from history and their famous sea voyages

Tenduc to _Tou Ch”eng_ or _Toto Ch”eng_, called _Togto_ or _Tokto_ by the
Mongols
[The following evidence shows, I think, that we must look for the city of
Tenduc to _Tou Ch”eng_ or _Toto Ch”eng_, called _Togto_ or _Tokto_ by the
Mongols. Mr. Rockhill (_Diary_, 18) passed through this place, and 5 _li_
south of it, reached on the Yellow River, Ho-k”ou (in Chinese) or Dugus or
Dugei (in Mongol). Gerbillon speaks of Toto in his sixth voyage in
Tartary. (_Du Halde_, IV. 345.) Mr. Rockhill adds that he cannot but think
that Yule overlooked the existence of Togto when he identified Kwei-hwa
Ch”eng with Tenduc. Tou Ch”eng is two days” march west of Kwei-hwa Ch”eng,
‘On the loess hill behind this place are the ruins of a large camp,
Orch”eng, in all likelihood the site of the old town’ (l.c. 18). M. Bonin
(_J. As._ XV. 1900, 589) shares Mr. Rockhill”s opinion. From Kwei-hwa
Ch”eng, M. Bonin went by the valley of the Hei Shui River to the Hwang Ho;
at the junction of the two rivers stands the village of Ho-k”au (Ho-k”ou)
south of the small town To Ch”eng, surmounted by the ruins of the old
square Mongol stronghold of Tokto, the walls of which are still in a good
state of preservation.–(_La Gographie_, I. 1901, p. 116.)
