As to the best means of conveying the water from this point, and as to what 
advantage, if any, would he gained, from an engineering point of view, by taking the 
water from here instead of from above Bight’s Falls, it is not for us to say. The 
distance saved in a straight line would not be great; hut it may be the engineering 
would be simpler. 
There are still, however, two alternatives possible. The one is, to enlarge the 
reservoir at the Botanic Gardens, so as to make it capable of storing a six weeks’ 
supply. If this were done the water could be taken in at a point of the river not far 
removed from the present pumping station. The other is to dam back the salt water 
by submerged flood-gates above the Prince’s Bridge. As to which would be most 
feasible and economical, from au engineering point of view, we cannot say. 
In conclusion we have to acknowledge that the main labour of gathering and 
testing the samples for the purpose of this investigation has devolved upon Mr. P. R. 
Scott, the water analysis assistant in the Agricultural Laboratory. 
We have the honour to be, Sir, 
Your most obedient servants, 
C. R. BLACKETT, 
Government Analyst.
