* Note. — These totals and their constituent figures are the sums of the daily observations of the Indus in cusecs.
To arrive at its total discharge during the period concerned, the figures given in the table must be multiplied by
86,400 (the number of seconds in a day.)
The observations at Dera Gazi Khan during the cold weather were discontinued this
year and in their place observations at Mithankot, above and below the junction of the
Chenab with the Indus, w r ere instituted. The latter observations will in future be continued. -
As the Mithankot discharges were measured from the middle of January to the end of March,
