"There are just twenty of us, sir, without you, and nineteen dinners. So if you divide among us four dinners a day, it will last for five days, and by that time I hope we shall be free."

Four men only could work at the face of the stall together, and Jack divided the twenty into five sets.

"We will work in quarter-of-an-hour shifts at first," he said; "that will give an hour's rest to a quarter of an hour's work, and a man can work well, we know, for a quarter of an hour. When we get done up, we will have half-hour shifts, which will give two hours for a sleep in between."

The men of the first shift, stripped as usual to the waist, set to work without an instant's delay; and the vigour and swiftness with which the blows fell upon the face of the rock would have told experienced miners that the men who struck them were working for life or death. Those unemployed, Jack took into the adjacent stalls and set them to work to clear a narrow strip of the floor next to the upper wall, then to cut a little groove in the rocky floor to intercept the water as it slowly trickled in, and lead it to small hollows which they were to make in the solid rock. The water coming through the two stalls would, thus collected, be ample for their wants. Jack then started to see how the men at work at the doors were getting on. These had already nearly finished their tasks. On the road leading to the main workings choke-damp had been met with at a distance of fifty yards from the stall; but upon the upper road it was several hundred yards before it was found. On the other two roads it was over a hundred yards. The men had torn strips off their flannel jackets and had thrust them into the crevices of the doors, and had then plastered mud from the roadway on thickly, and there was no reason to fear any irruption of choke-damp, unless, indeed, an explosion should take place so violent as to blow in the doors. This, however, was unlikely, as, with a fire burning, the gas would ignite as it came out; and although there might be many minor explosions, there would scarcely be one so serious as the first two which had taken place.

The work at the doors and the water being over, the men all gathered in the stall. Then Jack insisted on an equal division of the tobacco, of which almost all the miners possessed some—for colliers, forbidden to smoke, often chew tobacco, and the tobacco might therefore be regarded both as a luxury, and as being very valuable in assisting the men to keep down the pangs of hunger. This had to be divided only into twenty shares, as Mr. Brook said that he could not use it in that way, and that he had, moreover, a couple of cigars in his pocket, which he could suck if hard driven to it.

Now that they were together again, all the lamps were extinguished save the two required by the men employed. With work to be done, and a hope of ultimate release, the men's spirits rose, and between their spells they talked, and now and then even a laugh was heard.

Mr. Brook, although unable to do a share of the work, was very valuable in aiding to keep up their spirits, by his hopeful talk, and by anecdotes of people who had been in great danger in many ways in different parts of the world, but who had finally escaped.

Sometimes one or other of the men would propose a hymn—for among miners, as among sailors, there is at heart a deep religious feeling, consequent upon a life which may at any moment be cut short—and then their deep voices would rise together, while the blows of the sledges and picks would keep time to the swing of the tune. On the advice of Mr. Brook the men divided their portions of food, small as they were, into two parts, to be eaten twelve hours apart; for as the work would proceed without interruption night and day, it was better to eat, however little, every twelve hours, than to go twenty-four without food.

The first twenty-four hours over, the stall—or rather the heading, for it was now driven as narrow as it was possible for four men to work simultaneously—had greatly advanced; indeed it would have been difficult even for a miner to believe that so much work had been done in the time. There was, however, no change in the appearances; the water still trickled in, but they could not perceive that it came faster than before. As fast as the coal fell—for fortunately the seam was over four feet thick, so that they did not have to work upon the rock—it was removed by the set of men who were next for work, so that there was not a minute lost from this cause.

During the next twenty-four hours almost as much work was done as during the first; but upon the third there was a decided falling off. The scanty food was telling upon them now. The shifts were lengthened to an hour to allow longer time for sleep between each spell of work, and each set of men, when relieved, threw themselves down exhausted, and slept for three hours, until it was their turn to wake up and remove the coal as the set at work got it down.
