I chose for various reasons the cellar as the spot at which to make the first attempt. In the first place it was already dug down to a certain depth, so that the labour would be less; and in the second, my working could be kept more secret. In clearing the foundations of the house the workmen had gone down to the rock nearly all round. Just at the end of Witsennan point there seemed to be a sort of bowl-like hollow, where the thin skin of earth lay deeper than elsewhere. It was here that the cellar was dug out, and the labour of cutting or blasting the rock saved. With a pick-axe I broke and stripped away a large patch of the concrete in the centre of the cellar, and in a short time had dug and shovelled away the earth and sand which lay between the floor level and the bed rock. I cleared away till the rock was bare some four or five feet square, before I commenced to work on it. I laboured furiously. What I wanted was work, active work which would tire my muscles and keep my thoughts from working into channels of gloom and disintegration.
It took me some time to get into the way of using the tools. It is all very well in theory for a prisoner to get out of a jail or a fortress by the aid of a bit of scrap iron. Let any one try it in real life; under the most favourable conditions, and with the best tools available, he will come to the conclusion that romancing is easy work. I had the very latest American devices, including a bit-and-brace which one could lean on and work without stooping, and diamond patent drills which could, compared with ordinary tools of the old pattern, eat their way into rock at an incredible rate. My ground was on the gneiss side of the geological division. Had it been on the granite side of the line my labour and its rapidity might have been different.
I worked away hour after hour, and fatigue seemed to
