To Colotlel Sir G~1ta1.o I ~~N~x-COX~NG~~.~M,
ILK., who succeeded to t.he cl~arge of the
Trigono~netrical Survey it1 1913, I an1 indebted for nluch kind helpin
Support of Tngouom.
Survcg Office, conncctio~~ with tny tl~irtl expedition antl for niost of the etforts which wen
needed to assure the publication of the maps dealt with in t111s Memoir
My gratitude for llie constant considetation and sultport must be all the greater because the
protracteil labours needed for t.he conipilation and fair-dr:iwing of tliesc maps at the Trigonometrical
Survey O5ce had to be carried on for the most part duri~rg the period of great stress
and strain when the war caused del~letiorl in the Survey staff. To Colonels E. A. TANDY, 1t.E..
and H. Xlc C. Cowis, R.E., ~lto successirely Ilcld charge of the Trigonometrical Survey Oftice
since 1920, tny - special - t,llanks are clue for the stcatlily c-onti~loed efforts wllich permitted the
reprolluction of the large tlutnber of map sheets to be completed by the summer of 1922.
The greatness of t11v field covered by our survcys, extendin?. over no less than 28
degrees of longitode and 8 degrees of latitulle, and thc varied nature
Conipilation nod
drawi, of of the materials bro~lght back from the different journeys made the
task of conil)ilation ancl tlrawinr: necessarily a very heavy one. No
less than fiftceu draftsmen on the average wore employed on it during 191 7-1 9 under the
supervision of several oflicers from t,he Provincial and 1Jpper Subordin:~t,e Services, wor1;ing
at No. 2 Dratving Ofice, Deltra Dun. Under t,llr esce1)tional difficult,ies created by the
war, the work could not have been brought to a succossfnl conclusion but for the special
efforts which the oflicers successively in charge of it, Colonels G. A. BE,IZELEY and H.H.
TURNER and tlie late Colorlel R. A. ~VAI~IIOPE, It. E., mere prepared to devote t,o it by the side
of much other 11r~etlt worl;. To the last nanied oflicer in whom the Siirvey of India has
since lost a distinguished veteran of wide trans-frontier csyerience, I am indebted for a series of
valuable suggestions whicll have helped to improve the cartograpllic represeotnticn of the ground.
I owe a similar debt of gratitude to Major lc. J. i\I. KING, It. E., who since the sprrng
of 1919 adtling t,l~e cl~nrge of No. 2 Drawing Ofice to that of the
Reprodnction of
maps Photo.-Zinco. Onice, 1)ehla Dun, has spared no pains to improve the
reproduction of the maps by all tecllnical means at his disposal.
Finally J consider it. my duty to record 11ere my special thanks to PIunshi KAILIM BAKHSH,
Head Draftsman of No. 2 l)rawing Ofice, wlio brought to bear upon t.he drawing of the new
maps the accumulated experience he Lad gained ever sincc 1901 from the cartographic elaboration
of our previous Central-Asian surveys. His exemplary attention to detail and his
painstaking care helped to lighten t,he labour which the revision of the fair drawings and the
correction of proofs in their successive stage have involved for me.
when in the spring of 192 I Colouel C. H. D. RYI)ER, C. I. E., D. S. O., R. E., Surveyor
General, had accorded final sarlction for the pr~blication of the present
Appendices to
Memuir. Memoir, Major KENNE'PH RIASON,' IN. C., It. E., officiating Deltuty
Superintendent, Survey of India, kindly agreed, with the approval of
Colonel H. RfcC. Conrie, to provide for it an Appendix dealing with the detnils and merits of
the triangulation executed by my survey assistants, R. S. Rkm Singh a.nd R. B. LA Singh.
The lahour involved in this task mas far greater than t.lle snnimary and discussion as prefixed
by Major Mason in Appendix A might. suggest in its lucid conciseness. I cannot feel too
grateful to him for the expert analysis thus provided as regards t.lie trigonomctrical basis of our
maps. Not content with this service Major Mason decided to incorporate in the appended
tables and charts also tlie complete data available in the Computing Office, Dehra Dun, of the
triangulation work executed by other observers, including Iritnself, on the Piimirs antl along
the high K'un-lun ranges east\sards. It is hoped that the systematic record of these data will
prove useful towards facilitating the work cf future explorers.
I)r. J. de G~aarv HURTER, Deputy Superi~~tendent in charge of tile Computing Office
and Matltematicnl Adviser to tlie Survey of India, kindly rendered a service similarly I~elpful
by furnishing the notes of Appendix B on the height observations of my journey.;. They
explain the data and methods of correction used for the hetght records showr~ in tht maps
and incidentally affbrd guidance as to the better use of the hypsometer on future explorations
of this character.
