A MAN GOES SKY-ROCKETING THROUGH THE RIVER-BED
Nothing very exciting occurred until the last day of our contract week, That day started wrong. In the first place, the gang foreman failed to show up, and we went down the shaft without him, taking our regular places. Soon the superintendent came down and appointed one of the more experienced men foreman of the gang. That ‘s where the trouble first started.

Several men were outside of the shield at work in the different pockets. The new foreman climbed up into one of the upper pockets, when he noticed a bad leak at the edge of the “apron.” The apron in this case was a curved steel plate that projected from the upper part of the shield, like the poke of a sunbonnet,and protected the men below from material that might fall on them. It was supported by slanting braces. As soon as he saw the leak, the foreman called the men to bring up bags of sand and hay to choke up the hole. Two men climbed up through the door in the diaphragm with bags of sand. The first one, “Jerry,” was about to hand up the bag, and the other fellow, “Jake,” was right behind him, when suddenly, with a sound like a giantVol, XL,—81.
