ACCOUNT OF THE MATERIALS OF THE MAP. 
The following is a brief account of the documents from 
which the map accompanying the present work has been 
compiled. The river Irawadi is delineated from the sur¬ 
vey of Colonel Thomas Wood, with a few corrections, by 
the late Captain Grant. The survey of Colonel Wood, 
although executed above thirty years ago, when this officer 
accompanied the late Colonel Symes in his mission to Ava, 
is still, and after several more recent ones, the best ex¬ 
tant,—a sufficient proof of the skill and accuracy with 
which it was originally executed. The country forming 
the delta of the Irawadi, from Bassien to Rangoon, is taken 
from a sketch by Captain Alves, whose name I have fre¬ 
quently mentioned in the body of the work. The Saluen 
River and the province of Martaban generally, are taken 
from the surveys of Captain Grant. Much of the interior 
of the Burman dominions is from the sketches of Dr. Fran* 
cis Buchanan Hamilton, who, like Colonel Wood, accom¬ 
panied Colonel Symes in the first mission of that officer to 
Ava. Recent and actual inquiries have, in many cases, 
confirmed the geographical speculations—for, from the 
circumstances of his situation, they generally amounted to 
nothing more—of this gentleman ; a decided test of the
