In pursuance of this appointment he called at the lodging of Castles on the following Sunday morning, and produced several papers, one of which was a plan of the Tower, and another a plan of the machine, which he had described on the Thursday before, for obstructing the cavalry. It was to run upon four wheels, with sharp knives, which were to be on each side, and spikes in the middle. The knives were to be something like scythes, and placed horizontally. There were also several other drawings of the Tower-bridge, and different places and entrances about the Tower. "He then," continued Castles, "asked me how many men I could bring; and how many I knew. I told him I knew a great many, but I did not know whether they would act when put to the test; he begged I would exert myself as much as I could. I told him that I was a smith, and that I had nothing but my little business to live on; but he said never mind that, they would find something better for me than that; they had plenty of money for everything. We then made another appointment, and I met him at one Newton's. Similar conversation took place there, and he said they had got a committee consisting of five; namely Harrison, Preston, Thistlewood, and his son, and himself; and that I should be made one of the generals, and head a party of pikemen and other men, and that I should hear further in a few days, and might consider myself as one of the committee from that time; that I should make the sixth, and they would not have any more. "Shortly afterwards I met the elder Watson, and we went to King Street barracks, and across the Park to a small magazine in Hyde Park, where the powder is kept, to examine the whole of the avenues, and determine which was the best place for setting fire to the barracks. There was also one Skinner with us, but he left us in the Park, and Watson said he thought that Skinner had been a cleverer man than he was; that he intended to have made an officer of him, but he found him not at all calculated, as he had not any cultivated idea whatever.
