Took the drill out of the box sans trigger. Found trigger rammed it in all OK.

The super modified tub worked well zooming up the belt with full loads. Ever onward but a week off next week.

The data for most of this year. Rainfall at Taunton top and shaft water level bottom. There is a close relationship between the two though other factors like plant and tree growth come into play. The lowest theoretical shaft water level would be close to 9m thus opening up the lower drainage adit but this has not happened in the three years of monitoring. The second big shaft takes a lot of water in very wet spells. Not directly from the surface but a metre or so below the cap. The adit outflow runs the same most of the time so its all a balance of input over output. The adit clearly throttled by blockage somewhere. Of course as the water table lowers the hydrostatic pressure reduces thus decreasing the outflow. Maybe one day ---

Work continues with a trip on Sunday and another tomorrow. However its attritional and only creeping forward slowly. I will come back to this thread when something of note happens if ever. Meanwhile we have returned to our old digs at Fairy Cave Quarry at Quarter Way Up Hole.

Just a note to say thanks TOR for cataloguing this dig and for sharing it with us. I have enjoyed the story so far, the photos, the elaborate ironmongering, the hydrology and the slight mystery of its location. That all takes effort from you and I appreciate that.
