108 Dr Hamilton mi a Map of the Country between 
journey, while it reckons six days journey to this river from 
Kani ; but, in the map, the seven days occupy only forty- seven 
parts, while the six days occupy seventy-six parts. I suspect j 
however, that in the distance from Mredu to Msenghsen, the 
^ error is mine, and not that of the slave, and that I have read 
seven in place of what he intended for three, the Mranma cy- 
phers for these two numbers, when carelessly written, having a 
considerable resemblance. Whatever want of attention to a 
scale exists in this map, much useful intelligence may be col- 
lected from it, respecting the distances of places, the numbers 
in Roman characters, as usual, in these maps expressing days 
journeys, and those in cyphers expressing Dain or Mranma 
leagues of two and a half British miles road-measure. 
In extent, in climate, and in the magnitude of the noble 
rivers, by which it is bounded, the territory delineated in this 
map bears a strong resemblance to the Antarbeda or Duab, be- 
tween the Yamuna and the Ganges in Western India ; yet be- 
tween these two regions there are essential differences. The 
Antarbeda of Western India consists almost entirely of clay, 
sand, and loam, in which the Slightest vestige of stone cannot 
be traced ; and, farther, it is perfectly level, except where the 
bounding rivers, working on such soft materials, have excavated 
channels of great deptli, leaving enormous rugged clifts, which, 
in most places, render a descent to the river very difficult, and 
totally prevent the farmer from availing himself of their water 
for irrigation. In the Antarbeda of Eastern India, on the con- 
trary, and parallel to the Erawadi, there is a chain of rocky 
hills, the foundations of which prevent the river from sinkings 
so that, during the periodical rains, it inundates a great extent ; 
and, farther, this chain of hills gives rise to a stream, the Muk- 
hiaun, which has been already mentioned, {Phil. Journal^ 
Vol. IV. p. 83.), and which is advantageously applied to irriga- 
tion, forming two very extensive reservoirs, laid down with care 
in the accompanying map. From this it would also appear, 
that the southern portion of this chain bf hills, which is very 
rugged and barren, but not high, and which contains fine quar- 
ries of pure white marble, extends lo no great distance, that is 
to say, lor only about twenty miles in length, when it is inter- 
rupted by a level reaching from Mmngun, the usual country
