At the Barnsley West Riding Court yesterday, Tom Westwood, trammer, of Great Houghton pleaded not guilty to a charge of committing a breach of the Coal Mines Act.

Col Hewitt, who prosecuted, said on June 15 an ordinary safety pin was found inserted through the covering of the cable conveying electric power in the pit.

The cable carried 600 V, and one third of that power was sufficient to kill a man.

Defendant said he did not realise the danger of his action, and he could not say why he did it.

He was fined 40 shillings and costs.
