ALONG THE SOUTHERN FOOT OF THE ARKA-TAGH. 579
But this is not the place to linger longer in these regions, which were relatively well known even before my journey of i 893-97. In the third and fourth volumes of this work we have to deal with no other regions of Central Asia except the Tibetan plateau. After the digression occasioned by my description of the great northern latitudinal valley, we will now resume the thread of the narrative where we dropped it, and in the next volume I will continue my description of the middle parts of Tibet from our headquarters Camp XLIV onwards.
