After they were all sworn, and the fixed determination of hanging the first informer, a number of confidential persons were appointed as spies, to watch the conduct of others. We also appointed other trusty men to watch the movements of the turnkeys and sentries, and see that the prisoners held no conversation with either of them. We then divided ourselves into parties to work, and who were alternately to dig and relieve each other. After taking a correct survey of the ground, measuring and making it out, and taking the course, on the twentieth we made a beginning in both prisons, and dug directly down. In this perpendicular direction we must sink our work twenty feet, which would come on a horizontal plane with the road. On this horizontal plane we must then pursue the work, in an eastern direction, two hundred and fifty feet, which distance would carry us beyond the outer wall and under all the foundations which extended below the surface of the earth about six feet; if this work were performed we should then have a passage into the road. The digging could be carried on with very little difficulty: but the great obstacle before us was to convey away the dirt, and this, on a little consideration, seemed to vanish when we considered the stream of water in the yard, which passed under the prison at the rate of four miles an hour; into this stream we threw great quantities of fine dirt, which passed off. We, as another means to get clear of the dirt, obtained permission to bring into the prison a large quantity of lime, under the pretence of white-washing the walls of the prison. These walls were made of large rough stone, and every night we made of the dirt a sort of morter, and plastered on the walls, and then white-washed it over. No. 5 prison containing no prisoners, and not being visited by the keepers, we thought best to begin a similar operation in that prison, as we could pass and repass into it unknown to the keepers. In this we commenced digging in the day-time, and found a hollow place under the prison to stow the dirt away. In these three different places we made our attacks, and very rightly supposing, that if one should be discovered, that we should still have another, which we could proceed in without suspicion; we were apprehensive that the run of water, which passed through an iron grating at the outlet, might get stopped with the dirt, and lead to a discovery. We hastened on the work, every man as busy as a bee, and flushed with the hope and full belief that we should shortly make our escape. At the close of the month, we had dug toward the wall in a horizontal direction forty feet, without the least suspicion. As we entered so far under ground we found a want of fresh air, and to remedy this, we contrived a lamp to keep burning in the hole, that would expel all the axotic gas, or dead air, and bring in a constant supply of fresh.
