Note on the Bcdn-Nall in the Mahanuddy Basin. [No. 3, 
Now, if we suppose that hut for the great rain storm which produced 
the extraordinary flood, the rivers would have continued to run 
during this seven-day period, at the level at which they had been for 
some days previously ; they would have discharged per' second (vide 
Table 1G, Report Part II.) during this period— 
The Mahanuddy, 
„ Kajooree, .. 
Cubic feet 3,40,923

and in the seven days, cubic feet 6,35, 2G3 % / Y. 24 X GO X 60= 
384,207,062,400 cubic feet. 
Deducting from the whole discharge—

The above amount of » 384,207,062,400 
We obtain „ 377,565,580,800 
as the volume of water thrown into the Mahanuddy by the rain storm. 
Distributing this amount over the whole area above Cuttack we 
obtain 877,565,580,800 _q -3 f oc t 0 r 36 inches

45,000 x 5280 x 5280 
as the portion of the rainfall which found its way into the channel of 
the Mahanuddy ; and if we suppose this to be fths only of the total 
rainfall, that rainfall must have amounted to (inches 3'6 X f — ) 
9 inches. 
Question 2.— What must have been the rainfall throughout the 
year 1856 in the Mahanuddy Basin above the Delta, to have produced 
the discharge which has been calculated to have taken place at Cut- 
tack, as per subjoined extract from Table submitted with my Re- 
port Part II. vie . : —
