1879.] General Walker's Map of Turkestan. 187 
photo-zincography, by which the map has been re-produced for speedy 
publication. 
The new matter contained in the present as compared with the pre¬ 
vious edition, and the various sources from which it has been derived, are 
as follow:— 
Sheets 1 and 2 have not only been extended northwards from the 
47 th to the 48th parallel, but contain extensive additions, on the borders 
of the Caspian and Aral Seas, in Khiva and Bokhara and the Turkoman 
Desert and along the course of the River Oxus, and more particularly 
in Khokand and Hissar, the Alai Plateau, the Northern Pamir, and the 
independent States of Karategin and Darwaz. These have been mostly 
derived from the Russian Map of the Turkestan Military Circle, in 12 
sheets—published first at Turkestan in 1877, and afterwards with coi- 
rections, as a chromo-lithograph, at St. Petersburg in 1878—and other 
Russian maps of which early copies were obligingly forwarded to Gen¬ 
eral Walker by General Stubendorf, the Director of the Topographical 
Branch of the Russian War Office ; something also has been obtained from 
Russian maps published in the ‘ Geographical Magazine and from the 
maps accompanying Mr. Schuyler’s ‘ Turkestan' and Captain Buinaby s 
‘ Bide to Khiva.' 
It happens by a singular coincidence that, in the primary compila¬ 
tion of Sheet 2, the same error was made in accepting various details 
given in the Russian Map of the Upper Oxus Region (1878) which were 
afterwards proved to be erroneous, as was made in the compilation of the 
map Das Quellgehiet des Oxus, in Part I of Dr. Petermann’s Mittheilun- 
gen for 1879. At the time when the drawing of this sheet was com- 
menced, both the first edition of the Turkestan Map and the Map of the 
Upper Oxus Region were available ; the latter, being on a larger scale 
and much superior in finish and execution, and also being the later of the 
two, was accepted as accurate, pending a reference to General Stubendorf 
on the subject. His reply to General Walker was almost identical with 
his reply to the editors of the Mittheilmgen which is quoted at length 
in that Journal; happily it was received in time to permit of the erroneous 
matter being expunged and replaced by correct matter before the map 
was sent to press, which had not been practicable in the case of the Ger¬ 
man map. . 
In rendering the portions of Karategin and Darwaz which are most 
closely adjacent to the remarkable bend in the Panja branch of the River 
Oxus, the work of one of the Trans-Himalayan explorers—the Havildar— 
lias been more closely followed than by the compilers of the Russian 
maps • for, though the Havildar was not a finished surveyor, he certainly
