Occasionally the boy called the putter came by, shoving a rolley or little band-waggon before him. On to this the full corve was lifted and the empty one left in its place. Sometimes he proceeded by cutting a space on each side of the square bed of coal, from the roof to the floor. He then bored a hole in the middle of the block, into which he rammed a charge of gunpowder, and having lighted it by a slow match, retired to a distance. The powder exploding, shattered the whole mass, and it came tumbling down to the ground in fragments. This could only have been done where no foul air was present, otherwise the moment the lamp was opened there would have been a fearful explosion, and he, with many others, would perhaps have been killed. He laboured on incessantly until dinner time, when he and all the men in the working, including the putters, came out, and taking Mark with them, repaired to a central spot where there were casks of water, and seats, the only accommodation required by the rough miners. Here their dinners, which had been sent down during the morning, were eaten. "Well, how do you get on?" asked his uncle of Mark. "I kept awake, opened the door when the rolleys came by, and shut it again after they had passed!" answered Mark. "That's what I had to do!" said Simon. "I only wish that I had a candle, and had brought a book down to read. I should not have minded it much then, although it was a hard matter to keep awake!" "You were not afraid, then?" asked another man. "What was there to be afraid of?" asked Mark. "I heard noises, but I knew what they were, so I did not mind them!" "You'll do!" said his uncle in an approving tone. Mark ate his dinner, and then went back to his trap. He there sat all alone in the dark, anxiously waiting for "kenner" time. It came at last, and Mark heard the words "kenner, kenner," which had been shouted down the pit's mouth, passed along the galleries. It was the signal for the miners to knock off work, and return to the upper world. Mark, however, could not venture to move until his uncle came for him. He was very thankful when he saw the glimmer of a light along the gallery. Slowly it approached. It was carried by his uncle, who having closed the door, led him along through the main tunnel towards the shaft. Together they ascended, and returned home. Mrs Gilbart had been dreadfully alarmed at her son's absence, until told by a neighbour that she had seen him going along with his uncle towards the pit's mouth.
