Definition of "dead end"

The ventilation of dead ends — always a serious problem — has in some mines been an absolute necessity. At the Oriental Consols Gold Mine a crosscut at a depth of 2,600 ft. has been continued to over 1,400 ft. from the shaft, and at the No. 2 South Great Eastern Gold Mine crosscutting and driving has been carried on at depths of 1,750 ft. and 2,000 ft. In order to ventilate these dead ends blowers have been used to force air into the faces through lines of pipes.

Cut the ends of the hair once a month certain — no matter if you do cut but just the tips of a fourth of an inch, cut it. Cut off the dead ends every month as regularly as the new moon comes round.
