charged with an explosive to be fired by electricity, the charge being tamped with water or clay. Wires were laid connecting the several charges, and afterwards themselves connected with a cable, which was laid for a distance of about a hundred yards to a place where a galvanometer and firing battery were provided.
The duty of the deceased was confined to boring the holes, laying out the cable, and connecting the wires to it, the rest of the operations, including the firing, being conducted by Fleay himself. When the wires had been duly connected with the cable, it was itself connected with the galvanometer in order to ascertain that the circuit was complete. When this had been ascertained, Fleay, by holding up his hand, signalled to the deceased to indicate that the cable was about to be connected with the battery. In the ordinary course the deceased would then leave the stump and seek shelter. After an interval of about a minute, occupied in making connection with the battery, Fleay would fire the charge.
Fleay says that on the occasion of the fatal accident this practice was followed, and that on his making the usual signal the deceased acknowledged it, and walked away as if going for shelter. Fleay also says that just before firing he looked towards the stump and could not see him.
After the explosion took place the deceased was found to have been killed by it. It appeared from the nature of his injuries that he must have been close to the stump at the time of the discharge.
Upon these facts, which are not in dispute, it is contended that the fatal injury to the deceased did not arise out of his employment.
Mr. Pilkington relied upon the case of Plumb v. Cobden Flour Mills Co. Ltd. 1, in which two tests were suggested by Lord Dunedin as aids to assist in solving the question. The first relates to the case in which the injury has occurred in consequence of the disobedience of the workman to an order of his employer, and is put in this way: Did the order which was disobeyed limit the sphere of the employment, or was it merely a direction not to do certain things or to do them in a certain
