John Cooper, Pete Hann and Adrian Vanderplank. Slightly wetter today but not as bad as 3 weeks ago. Took in plastic sheet which Adrian installed in the bottom chamber to keep Pete dry when cementing in future weeks. On the way in Pete put 2oz fluoresceine in the soakaway at the bottom of the Entrance Shaft. After about 15 minutes working at the bottom the water flowing along the final rift turned green. It was still flowing green when we left an hour later. On the way out it was found to be entering near the bottom of Father Duckmas Shaft. Above that point the water was flowing clear. The water in the bottom chamber is more than twice that at the bottom of the Entrance Shaft. 1½ hours. John.
