So, the decision was taken to abandon digging at the base of the inlet and move out further into the choke, more or less directly below the new drop. This meant reshoring up the wall at the back and moving some of the stacked spoil behind it. With everyone finding themselves very busy it fell to Frank on a solo trip to install the appropriate planking. Personally I much admired the pictures of his handiwork from my sun lounger in Greece 8)
Franks solo shoring. Being more of a poet than a builder - it's the best he's ever done!

Very soon the full team was back on hand for serious hauling. When we had a big team the spoil went straight out to the surface ? Mick commanded it. If there was only four or less we built up another wall in front of the inlet and this eventually grew to quite a height.
There were some gaps appearing, annoyingly mostly right under the line of the shoring. The solid wall here haded downwards and we followed it. One day, Dave opened up a small hole and a good draught blew out of it. It was probably the best indicator yet of things to come. Some large limestone blocks started to appear which held back a lot of the clag and smaller debris, as long as they stayed put. Getting some scaffold in under these blocks to restrain them was key if not tricky. Whilst one side was resting on the solid wall the other was embedded in the debris some of which needed removing to make it large enough. This was still the fill from the surface pothole and, even by this stage was at least 20m deep.

The big guys shored in and the way on heading under the scaffolding
Never the less the big guys held and holes opened up headed back along the wall but away from our nice safe shaft. We had been in a solid corner but opted to follow the gaps which seemed to lead diagonally down to a passable 3m drop. With careful digging and shoring Bones eventually got down this, the wall cut under more and there were the tell-tale signs of clean washed cobbles. But the way on was back under ourselves, towards the corner. On two of the digging trips the draught did blow and this was obviously the right way to go. The draught was annoyingly inconsistent with some days not even a flutter. This seemed directly related to the atmospherics of the day, piling out when high pressure loomed, zilch in the mizzle and cloud.
Heading under away from the corner

Digging back under ourselves was fraught with problems of shoring and hauling out. Already you needed six or seven to get the bucket to the surface. We decided to abandon that route and go straight down in the corner through the thicker mud and rock, presuming it would get us to the same place as the source of the draught. We could also use the space of the original route for backfilling.
Change of plan - digging down in the corner
It took two or three trips to accomplish this, where hints of a roof appeared at foot level in the corner. More scaffold was needed and that required a further whip round for funds and a visit to Rolland in Kendal. Any breakthrough would have to come soon as we were nearing the limits of hauling efficiency?
Meanwhile on the surface winter is closing in. Geoff and Nick out in the cold - time to get underground
