EXPLOSION IN A COAL MINE. 



We regret to record the following fatal accident in the coal- 

 pit, at the Newton Green, Ayr : — About seven o'clock in the 

 morning of Thursday, 18th June, Mr. Miller, the manager of 

 the coal works belonging to Messrs. Taylors, in the prosecution 

 of his dutv, went into the pit ; and he and the oversman of the 

 pit, after providing themselves each with a safety- lamp, pro- 

 ceeded to examine a part of the mine wrought some time ago, 

 in order to open a door by which to increase the circulation of 

 the air, and they were followed at a little distance by six of the 

 ordinary colhers. When they had proceeded a considerable 

 way, the lamps indicated the presence of hydrogen; bat, having 

 confidence in their efficacy, they proceeded until both lamps be- 

 came red hot, and then the gas exploded, scorching and tossing 

 them about. The oversrnan, although severely burnt, escaped 

 with his life ; but the manager was found dead, from all appear- 

 ance suffocated by the choke damp which succeeded the explo- 

 sion. The colliers escaped with little or no injury, and the 

 oversman got out immediately; but the body of the manager was 

 not found till an hour or two afterwards. Mr. Miller was a 

 young man of exemplary conduct and promising abilities, and 

 his loss is much deplored. 



We cannot doubt that particular inquiries will be made into 

 all the circumstances of this explosion. In the mean time let 

 it serve as a caution to miners to be prudent and vigilant, and 

 to act with great circumspection when visiting old workings. 

 This, on the face of it, appears to be one of those cases in which
