AUSTRALIAN AGRICCLTURB. 



All Water should be Analysed. This is an absolutely 

 necessary precaution before laying out land for irrigation, 

 or applying water to land for agriculture, and is especially 

 necessary before using well or sewerage water. 



Irrigation from Wells At a huge strawberry 

 farm in Santa Clara, California, the author saw the effects 

 of irrigation from artesian wells, and the necessity that 

 exists for exposing water to the air before using it on crops. 

 In the case under notice an immense tank of concrete had 

 been raised some 10 feet above the level of the cultivated 

 land, which is level plain of great extent. In this tank 

 the well water was aerated, and mineral substances were got 

 rid of before the water was used. The elevation was suffi- 

 cient to give water pressure all over the cultivation land. 



Irrigation by Soakage. This process is followed 

 usually where capital and skill are brought to bear, and is in 

 general favor. Very efficient work of that kind is in opera- 

 tion at the sewerage farm, at Botany, connected with the 

 Sydney water supply. The land is laid out in levelled 

 paddocks, fields, or beds. Crops, such as lucerne, are sown

either upon this levelled land or the land is laid up in 

 ridges by the plough, and the crops are planted or sown 

 upon the ridges. The water is brought upon the land at a
