“The average irrigation for the five years in question was 442,302 inclusive of 11 per cent. which only receives first waterings. This divided by the average supply, 1,685, entering the head of a canal gives a duty of 263 acres per cusec at the heads of distributaries.

“The rabi irrigation of the new projects is 1,321,019 acres,[48] and this divided by 442,302 gives approximately the multiplier 3 referred to at (a) in the above table.
[48] Including the Lower Jhelum.
“The figures given in the above [table] and in the foregoing remarks relate to the aggregate of the areas in the rabi which receives a perennial supply and which only receives first and last waterings. On the Upper Bari Doab Canal the rabi which receives perennial irrigation is averagely 393,649 acres; the average supply of 1,685 cusecs gives on this area a duty of 234 acres per cusec at the heads of the distributaries.
“In the case of the three projects the aggregate rabi area receiving perennial irrigation as shown by the [table], paragraph 21[49] supra, is 1,164,595 acres: this is 2·96 times 393,649; so that the proportional supply required on this basis would be slightly less than that given by the multiplier 3 in the above [table].
[49] Not printed. The area is the total rabi area less the area which is to receive only first waterings.
In explanation of the difference of the duties:—
| Lower Chenab Canal | 208 | acres per cusec, |
| Upper Bari Doab Canal | 234 | ditto, |
