use the cntii-c force, or pressure, from artesiau flows obtainable can be made 

 available for all industrial purposes, with a greatly reduced cost, wider range 

 of application, and fuller adaptation to varying requirements, than has before 

 been reaUsed. Nothing in a mechanical way has so signally and quickly 

 proved its own usefulness, as well as its right to the first place in hydraulic- 

 power appliances. Every stream or waterfall, aad every bore outflow, is 

 a mine of energy that, by means of this most simple appliance, can be con- 

 verted directly into useful effect, witli almost entire absence of machinery, 

 and made available for any desired purpose, witli a high degree of efficiency 

 and comparatively small outlay.

" The following bore pressures (which may be taken as representative 

 ones) are from the New South Wales Government Report (1905), the other 

 calculations being made by myself. It will be seen that bore pressures are 

 of a very high value, as shown by the equivalent pressures from the high 

 heads of fallinfj water : —
