8 fresh and brackish or even salt water is 
struck in wells a few yards apart. It is, however, easily accounted for. Water- 
generally flows in channels under the earth’s surface, and starts fresh from its 
source, hundreds of miles away, perhaps passing through salt country in its 
course. It necessarily follows that much of the water will escape by infiltra-. 
tion, form into lesser streams, and, owing to the soil being saline or mineralised, 
the water in these lesser channels becomes the same, whereas that in the 
main channel, by reason of its flowing rapidly and continuously, remains fresh. 
If in sinking for water you miss the main stream, and strike a subsidiary one,. 
the result is bad water. It is a well-known fact that most underground streams 
are serpentine, so that 50 wells might be sunk but not one of them in the right 
spot. Imagine the Darling River an underground stream. We know there is 
an abundance of fresh water there. At the same time 100 wells could be sunk 
and all of them might happen to be on the bends, in which case either there 
would be no water or it would be salt, though perhaps within 20 feet of the- 
river. ‘This is where the divining rod is of service,
