[1] Originally given as a temporary advance for six pays, afterwards converted into an ordinary advance.
[2] Originally given for six pays, afterwards continued for further period of six pays, and again extended until pays ending 15th and 22nd April 1899; it was then continued as an ordinary advance.
[3] Of this advance one and a quarter per cent. was given for seven pays, and afterwards merged in the ordinary percentage.

A THEORY SHOWING HOW COAL DUST IS IGNITED AND EXPLODED IN A COAL MINE, MORE ESPECIALLY ON IN-TAKE AIR ROADS
In the first place, there must be a considerable quantity of very fine and dry coal dust in the immediate proximity of a shot when fired; and if the shot is a strong one the concussion will be very great.
This force, acting on the air, throws the finest particles of coal dust into the circulating current, in a finely divided state, with orbid motion, thereby causing each particle of coal dust to be surrounded with air, and these particles of dust in this condition coming in contact with the flame of a shot, are easily ignited.
