Isaac Hartley
One of the accidents (No. 6 in the list) caused the deaths of three men, and, although very serious in its consequences, was not of a nature altogether uncommon where minerals are worked in large veins. The vein in which the occurrence took place is about 10 to 15 feet wide, and the mode of working adopted is to drive drifts in the vein at various levels, leaving from 10 to 12 feet thickness of solid mineral, locally termed middlings, between each level, which is afterwards removed, or as much of it as possible, by robbing. In the process of working a very large area of "overhanging" side becomes exposed, and this, if it gives way, brings a collapse or crush on all the workings within its influence. Fortunately, generally speaking, when such a thing is about to occur, indications are apparent for a considerable time, and in this case it would appear that it was not altogether unexpected. The crush came, however, sooner than was expected, and buried the three men in the debris. The accident was a subject of long and searching inquiry, but I felt satisfied that care had been exercised in working the mine. The Coroner's Jury did not feel at liberty to append any recommendations to a verdict of Accidental Death.
