the underground flowage, and bring into operation desiccating conditions 
It is urged that here, as in all other districts where artesian wells are 
in use, the flow of a well should be regulated, and that a stop-tap should 
required. In the case of every borough and township a pressure-gauge 
each other by not less than a quarter of a mile. Many facts of public 
use could be gathered if the authorities would agree to work together, 
and I do not doubt that the artesian beds underneath the Heretaunga Plain 
could be preserved for many years by careful attention to the condition 
of the wells. If it has been deemed necessary to establish a River- 
conservation Board, surely the need is as great In the matter of water- 
conservation for domestic use. Under a properly constituted authority 
a vast amount of information might be collected as to flowage, corrosion я 
pipes, changes in the pressure, and the changing character of the materials 
held in solution. These facts could be used to suggest profit and ets 
the sources of supply, and the corrosion of pipes, and even as to whether 
creeps are taking place in overlying beds.
