My first action on reaching the bottom of the shaft was to taste the water. To my great relief I found that it was fresh, and we, therefore, had no reason to suppose that we should not be able to contend with this difficulty, as we had with so many before.

It was impossible to approach the head-wall in the lower heading, and the door there was open ; but men went up to see that the door in the upper heading was properly closed, and to put additional timbers in the sloping heading to secure the head-wall there.

As there was a hole existing from the tunnel at Sudbrook to the new pumping-shaft on the south side of the line, bricklayers were at once started to close this hole with brickwork in cement. As soon as these works were started, I ascertained the following facts with regard to the inburst of the water.
