566 Lieutenant Burnes’ Memoir on the 
river, selecting that month because the floods in the Indus would have pro- 
perly set in before I arrived, and the opportunity, on that account, would 
be very favourable for its examination. In the intermediate time, too, 
between March 1827 and August 1828, I had visited the whole northern 
frontier of the Bombay Presidency, from Lacpat to the mountain of Abi, 
and had minutely examined all the islands on the Runn, and the Runn 
itself at every point, as well on the borders of Guzerat as at Pdrcar, 
it appearing to me that it would be necessary to bring that singular tract of 
country clearly under review to comprehend fully the alterations which the 
Indus had undergone. The following sheets, therefore, will be found 
to contain a theory on the formation, filling, &c. of the Runn, with many 
novel opinions concerning it, which I have no where met with, and which 
are nevertheless founded upon those facts only which have come under my 
personal observation. 
I sailed from Lacpat to Allah-band on the 9th of August, which, as may 
be remarked, is about the period when the south-westerly winds blow with 
the greatest violence, and I was, therefore, prepared to meet a greater body 
of water, and found the inland lake, before described, deeper by two feet, 
and the river increased in proportion. The channel through the Al/ah-band 
I found to be wider, with more of the west side washed away, and changed 
from a sloping declivity to a perpendicular bank, like the eastern shore. I 
sailed two miles up the river or channel which the flood of 1826 cut 
through Allah-band, and found the water gradually to decrease from two 
and a-half fathoms to as many feet, which I was informed was its depth as 
high up as Chatitar, above Ali band, and about twenty miles distant, 
where the water comes from the Ginz river, and to which the flat-bot- 
tomed boats could still ascend. This proved, at all events, that the bands 
have not been again thrown up in the P’harran river, though I could glean 
no more positive information on this head than I have already given. 
The grand embankment called Arrore, the bursting of which produced 
the changes before described, has been renewed, which will fully account 
for the decrease of water from the channel of the river between Allah-Land 
and Chatitdr. The greater distance which I ascended the river gave me a 
clearer view of the effects of the inundation of 1826; the banks of the 
channel which it cut through are of clay, and as they are perpendicular, 
and the river comes directly from the north, without any windings, I can
