however a matter of detail.
(13)
It is at present, I think,
unnecessary to
discuss details of construction.
The scheme as a
521
whole is sound in principle, and I recommend its adoption.
Any questions of detail may be discussed hereafter.
(14) It will be well to continue the records of
rainfall, and discharge from gathering-grounds.
If
not already done, rain-gauges should be established on the several gathering-grounds. The weak point in the
experimental data, available up to date is the absence of
any measurement of the overflow from the reservoirs. The existing bywashes do not lend themselves to
accurate measurement of the overflow.
In new construc-
tions, it will be well to arrange the overflows so that
a fair approximation to the discharge may be obtained.
I have the honour to be,
Gentlemen,
Your obedient servant,
