I'd always been fascinated by 'what lies underneath the ground' and at about the age of 13 I dug a huge pit in our garden, in the floor of our old Anderson, eventually arriving at a bed of gravel lying some 8 feet down. The following day I discovered there was a lot of clear water flowing across my pit; I'd struck an amazing underground river! This epic news was not well received by Ma, - who stored her garden tools there - so it was promptly filled in again.
