on the bracing herewith furnished, this wall to be built as the Engineer proposes.
E would make the Tanks larger than shown in the Engineer's drawing, dispensing with the inner and end walls and the bottom lining of concrete.
This will add this much capacity, but I would still further enlarge the Tanks to the extent I have shown.
It will be noted that there are set-offs on the inner face of the wall. These will hold to the proposed lining.
I have enabled better cementing.
I have no means to alter or modify the estimates.
The word "Pley (Fire Pley)" is used by the Engineer. I trust this is an inadvertent slip and means Five fire hydrants, a different and more modern appliance than the old ones now discarded in modern water works.
The heads detailed, namely 410 feet, 385 feet, and 250 feet, will give effective service in each case. The total volume of water at command, upwards of 600,000 gallons, is not large, and great care will be required to make it effective in use at the commencement of a fire.
It is at the commencement, almost exclusively, that water under pressure is of most use. "Fire is not subdued by showers of water in drops but by bulk and force." That is, by a large volume.
