PROCEEDINGS OF SECTION B. 
Remarks . — The water gave an alkaline reaction to litmus paper, 
due to the carbonated alkali present. Contains a very small amount 
of suspended matter, which consists almost entirely of carbonate of 
lime. No poisonous metals detected. 
This water contains more carbonate of soda than hitherto found 
in the waters examined from this district. I am of opinion, however, 
that with careful use and deep drainage this water is suitable for 
irrigation purposes.

opinion that the water from this bore may be used for irrigation

The soluble saline matter consists mainly of alkaline carbonates, 
chloride of sodium, sulphuric acid, &c . ; the “insoluble,” of silica and 
traces of carbonate of lime and magnesia. The water gave an alkaline 
reaction before and after evaporation. The quantity of water received 
in both samples (Native Dog and Youngerrina) was too small to enable 
a more detailed analysis being made ; these waters may be used for 
irrigation purposes, and are suitable for all domestic purposes. 
It will be observed that the saline matter consists mainly of 
carbonated alkalies, which are known when present in large quantities 
to exert a serious influence on plant life by their corrosive action on
