My father told me that he and his dad used to do water witching when he was a boy out on the farm. It always worked for them. I think the explanation above is a feasible explanation. Delilah's aunt (a Witness) used to do water witching and I know she was spoken to by the elders about "dabbling in demonizm".
Funny you should mention this, Mary, I was about to...My aunt's m/i/l did the water witching as well, she was never a witness, and she always found water. They were never without water on their two farms. Imagine, the debbil looking after a witness family...hahahaha
