Now it was getting a little hairy. It was 10pm and we were not hitting bottom with the probe. We were running out of room in the neighbors flat and the 30 foot chain ladder was starting to worry us also. It was rolled out at 30 feet and there was at least 7 foot left to dig to hit bottom. I was in the hole when I decided I had enough. I was down there for over half an hour. When I made my way out I realized I had left the light the probe and my shovel down there, I thought someone would go next to dig. But no one wanted to go down. We were pretty much beat up. We had to fill it in when we were done and that was going to take super human strength. Don decided to go back down to get the tools and scratch around a bit more. He probed one more time and the 6 foot probe sunk to the handle! with out touching bottom! That meant there was a lot left to go and we were out of space ,energy and ladder length. This Monster privy may have gone 40 feet or more! It is a shame we could not finish it. I know the bottom was pontil age. The house was built in 1858. No doubt it would have had some cool civil war era stuff down there also. We did not know what to expect when we started this thing. Next time we will have a longer ladder!
