APPENDIX E.
MATERIALS OF THE MAP.
The maps for the present work were compiled and engraved
by Mr. John Walker, a gentleman who has long
and successfully cultivated the field o f Asiatic geography.
I f I may presume to offer an opinion, he has on the present
occasion skilfully availed himself of the scanty materials
which were placed in his hands. Of these the following
is a short account:—
The Province of Martaban is delineated from a survey
by Captain Grant, o f the Indian Surveyor-General’s department.
The country between the Martaban river and
Tavoy is taken from a survey by Captain John Lowe, who
travelled over it. From Tavoy to Mergui is from a map
furnished by Mr. Maingay, the officer in civil charge of our
recent acquisitions to the south of the Martaban r iv e r ;
and from Mergui to Junk Ceylon is taken from a sketch
by Captain Burney, who visited this part o f the coast.
Penang and its neighbourhood are delineated from an actual
survey by Mr. Fletcher. Singapore and the adjacent
islands are taken from surveys by Captain Franklin and
Lieutenant Jackson. The Malayan Peninsula throughout
is delineated from the accurate nautical charts o f Captain
Horsburgh. From the Cape of Patani to the point of
Kwi is taken from a Mohammedan mariner, a native of
Siam, possessed of considerable intelligence-—who was acquainted
with the use of maps and the quarter-staff, and
could even take an altitude of the sun with our quadrants;
no mean proficiency in an Indian.
Th e head of the G ulf o f Siam and its eastern shore,
down to Kangkao or Hatian, are from the same authority;
many points being determined, and the whole arranged
and adjusted by Captain John Brown, the commander of
the John Adam.
The interior of Siam is laid down from a map prepared
for me by my friend Captain Taylor, who drew his materials
from the Siamese authority already mentioned—from
La Loubere, and Dr. Francis Buchannan Hamilton. From
Kangkao to the great river of Kamboja, is taken from an
eye sketch of Mr. Dyot. The coast of Cochin China, as
far as the Bay of Turan, together with the mouths of the
Kamboja and Saigun rivers, are taken from the actual surveys
of M. Dyot, corrected by Captain D. Ross. The
river of Tonquin is delineated from a sketch in the collection
of Mr. Dalrymple.
