XLVI. HYDRAULIC ASPECT OF THE ARTESIAN PROBLEM. 
(b) Comprehensive and deliberate investigation. 
(c) Opportunity to make required tests at the various 
bores. vf “83 
(d) Insistence in future that complete and accurate 
records of all strata pierced shall be kept. 
(e) Insistence on the making of suitable flow and pressure 
observations at new bores. 
(f) Utilisation of all other sources of knowledge, i.e., 
geology, chemistry, biology, ete. 
Thirdly, ‘When should the investigation be made?’ The 
observation of the phanomena of varying pressure and 
efflux, should undoubtedly have commenced when the 
first bore was opened, and should have been going on ever 
since. As previously stated, the difficulty has been seri- 
ously increased by neglect to do this, and the longer the - 
lapse of time before we start, the greater the region of 
uncertainty in the resulting information. For in rightly 
deciding the most probable initial pressures and other con- 
ditions in the artesian stratum, lies the true solution of the 
problem, The failure of our artesian supplies would be a 
great calamity, and too big a price to pay for any want of 
foresight. 
2. Necessity for legislative control of frequency of 
bores.—A rule for determining how far it is wise to allow 
the tapping of the artesian sources, must be dependent upon 
the results of the investigation indicated. .There is no 
other exact way of deciding which is not wise after the 
event. The solution must not be through disaster. The 
interference of one bore with another, and the possibility 
of general failure, all go to shew how careful should be 
the control of the whole matter. Boring is a matter of 
some expense, and the best control in the common interest 
is the crux of the solution, and asks urgently for that
