The author showed interesting photographs of a current-wheel which he had 

 constructed and erected at Alexandra, and gave an account of its power and work- 

 ing-capacity, and the quantity of water it could lift and discharge, and showed 

 clearly that there was an almost unlimited supply of power entirely untouched in 

 the midst of a great district with enormous possibilities in the way of fruit-pro- 

 duction under a comparatively economical system of irrigation. In the course of 

 the discussion that followed Mr. Payne stated that the wheels could be multiplied 

 indefinitely on a river such as the Clutha, and that the cost per head by current- 

 wheel was about £500, as against £1,400 per head for water brought in by the 

 usual pipe-lines.
