Futterer emphazises that in spite of the ordinary expression »Tibetan plateau-
land» which is correct from a merely morphological point of view, the southern
part of High Asia, from a geological point of view is a region of folds. Only the
highest ridges crop up as mountain ranges. All depressions are filled with deposits
and the remains of destruction, which in an enormous scale have levelled the sur-
face. It is impossible to imagine the height of the peaks of these old folded chains
which must have been enormous considering the tremendous masses of débris filling
up all the intermediate depressions between the gigantic ranges and reaching to a
very considerable height at the sides of the present ranges. The result of this
destructive and accumulating action is the plateau-land of Tibet as we know it at
present.

In spite of the geological profiles existing, Futterer regards the structure of
the mountain region between the Western Kwen-lun and the Kara-korum as well as
of the Western Kwen-lun itself as not quite clear. He says:

Wenn v. Richthofen angibt, dass die von S. O. nach N. W. gerichteten Ketten gegen
W. N. W. und schliesslich WzN. umbiegen, und dass dadurch ein allmähliches Anschmiegen
derselben an den westlichen Kwen-lun in ähnlicher Weise stattfinde, wie dies an seinem
östlichen Ende seitens der sinischen Ketten geschieht, so steht damit die Auffassung von
Suess nicht in Einklang, der als merkwürdige Thatsache nach Stoliczkas Berichten kon-
statiert, »dass der Kwen-lun selbst gegen N. N. W. abschwenkend jenes grosse Gebirge
bildet, welches sich westlich über Jarkand und Kaschgar erhebt und in der Regel als
Kizilyart bezeichnet wird».

FUTTERER agrees with WEGENER that the Dupleix Range may be regarded
as a western continuation of the Tang-la chains. On the other hand he finds it
doubtful that the Tsa-tsa-Daban and other neighbouring ranges may be the western
end of the Tang-la-Dupleix System. And if the Tang-la, Dupleix and Tsa-tsa
really form one and the same system, he finds it doubtful in the same degree
that this system can be the tectonic continuation of the Western Kwen-lun and
the Kizil-yart with their N. W.— S. E. stretching ranges. If such a range really
existed, for instance somewhere south of Keriya, BOGDANOVITCH would have
brought clearness to the problem. But judging from his map, no E. S. E. stretching
range exists in the region south of the Western Kwen-lun. LOCZY has only dared
to indicate with a dotted line the possibility of such a connection. Already in
1904 when I wrote Vol. IV of my Scientific Results of a Journey in Central
Asia 1899—1902, I felt sure that the view of WEGENER could not be correct,
and that FUTTERER was right in his doubts. My own view appears from Pl. 69
in the volume quoted.

On his and Dr. Holderer's two years' journey through Asia, undertaken from
November 1897, Futterer had no opportunity to contribute to the knowledge of the
