others have been partially affected by the loss of sons ; but all of 

 them have had great attention and humanity shown them by the 

 owners of the colliery. In the progress of procuring the bodies no 

 part of the mine appeared to have been set on fire: not a cinder or 

 singed prop was seen in any part of it. On Tuesday the ventilation 

 for the renewal of working it was commenced, and regularly carried 

 on till Thursday morning, about eight o'clock, when the workmen 

 were suddenly alarmed by finding the coal on fire in a part of the 

 waste. From this circumstance it was immediately determined to 

 close up the mouths of the shafts.
