15 other two were only two yards wide, and were the air’s return passages, as thered dart and crossing, one stenting down, show, and the crossing over the mam horseway one pillar east of the engine. There is a barrier of coal left rorty or titty yards thick on the south side of the water level board, and nmnmg; parallel therewith the full extent of the mine to south and east, i aS 4.1 in^en^on °f the authorities to put these stoppings in the barrier e ow the water level board; and, on a day when the pit was off work (excep ie deputies and wastemen), the overmen set two of the deputies .°.J'nt °ut tiie ground work for the monster stopping in the centre amt. 1 had then no knowledge of this, but before the day was over Happened to go where the process was going on, and found the hands at work. 1 asked them what they were doing there ? They told me all icy knew. I then turned to the overman, and asked him if it was intended to stop off the goaf in that manner. He said, “I do not know Jiit 1 was ordered to set these men on, as you see them.” “ Well ” 1 ?? 1;!bour T1 vai1!’and y°u know it ought not to be done, and cannot be done ; I would not continue in a pit with a goaf barred off under any consideration.” The following day, in a conversation with the under-viewer, I discovered that my remarks had been taken hold of which gave us an opportunity to discuss the subject freely. I asked his permission to try the experiment, which he gave with a good grace. We then put a twenty meh stopping in the centre drift, as a necessity to its permanency, and the security of the goaf; but in the east headways we put only a ten inch stopping, at the same time making every other part safe against accident, &c. We now had this goaf stopped off, and it might continue to be so for months, it might be years. Yet still it was iraught with danger, as 1 will show you. (Consult the Plan.)
