After the sweets have come away, cold water is passed through the char until no trace of lime or sulphate of lime is found in it; then a large manhole at the bottom of the cistern is opened, and the washed and spent char is removed.
One of the crewmembers entered the manhole to unclog the hose.
The sea was smooth, the night dark with wind from N.W., but hardly had the ships left Dunkirk when the "Sappho" blew out a manhole joint in her boiler and had to put back.
Entrance is up the gill on the right beneath a covered manhole.
Goring reported problems with blocked waste pipes to the Pavilion, which did not have the necessary manhole covers on them.
