The iiiaiM points dealt witli in tliis ])aper are the fullowiii^ : — 



(1) The fixing of atmospheric nitrogen by electricit\- in the pi-oductioii 



of tile fertilising agent known as C'aleiuin Nitrates, by tlif Uiikclaiid- 

 Eyde process. 



(2) A second process of a similar character resulting in the production 



of the fertiliser called Calcium Cyamimide or Nitrolim.

(11) Experiments with electrified seed-wheat in South Australia, and 

 with various seeds at Werris Creek. 



(12) The practicability of establishing nitrogen-fixing industries in 

 Australia, and the i)robable forces available for generating the- 

 electricity. 



(1.3) Electricity in farm household life and in fi(>ld machinery operations 

 in other countries.
