1841.] Wood's Report on the River Indus. 519 



Breadth of the Stream. — The width of the surface water in the dry 

 season, varies from 480 to 1600 yards ; the usual width is about 

 680 yards. 



Depth, — When the river is in full freshes twenty-four feet ; but 

 in an opposite season of the year, nine, twelve, thirteen, and fifteen 

 feet are the usual maxima of its soundings. The greatest depth of 

 water in the Indus occars between Kalabagh and Attock ; one hun- 

 dred and eighty-six feet has been here sounded. 



Velocity. — Seven knots an hour in the freshes, and three when the 

 river is low. It is scarcely necessary to remark, that the three last 

 items are very inconstant. At no two places are the measurements 

 exactly alike, nor do they continue the same at one place for a single 

 week. A more particular account of these will be found under the 

 next head. 



Fall per mile. — From Attock to Kalabagh, . . . . 20 inches. 

 Ditto Kalabagh to Mittun, .. .. 8 ditto. 

 Ditto Mittun to Sea,* 6 ditto. 



Discharge per second.— Cnhic feet Maximum — 

 in August, 446,080 



Maximum in December, 40.857 



Annual Z)2.sc^ar^e.— 5,383,600,934,400— or 150,212,079,642 tons 

 avoirdupois. 



Power of Transport.— -Rolled pebbles do not occur in the bed of 

 the Indus below Chandia-ke-kote, a village five miles South of Kala- 

 bagh. Above Kote, though not below it, the sand of the Indus is 

 searched for gold. The precious mineral is also found at Dera Ismail 

 Khan ; but not in the river. 



It is washed down by the rains from the Soliman mountains. 

 Pebbles also occur at a certain spot in the river below Hyderabad, 

 in Lower Sinde; but they can be traced to hills in the neighbourhood. 



Height of the River's BawA:^.-— Assuming for the purpose of expla- 

 nation that the source and the embochure of the Indus are upon 

 the same level, the river in its long course may be said to have 

 two maxima of rise. These are shewn in the following sketch, where 

 the measurements are those of the stream when in full flood.
