I have had models of the machines made here. Those interested in mechanics will discover for themselves the mechanical defects and unnecessary complications introduced into them. I was working under the supervision of fairly good mechanical engineers, so that defects might not be made too glaring. Some were detected and rectified, but the main defects were not seen, being beyond the powers of calculation of Abdallah; and Hamaida, who could and did see them, was enjoying the pranks which were played. The various ideas I had picked up while associated with Gordon's old corps were now standing me in good stead. When the model of the cartridge machine was taken over to Abdullahi, instead of being pleased with it he was furious: Berber had been taken! He said, "I want cartridges, not models;" and gave orders that I should be taken from my house, kept at work all day in the arsenal, and locked up at night in the arsenal prison with the convicts employed there as labourers.
To gain more time, I insisted upon a full-sized wooden model of the cartridge-machine being first made for the metal workers to work from. Yacoub had given orders that all the material and labour of the arsenal was to be put at my disposition. While the wooden model was being made, I occupied myself in selecting the metal required, and in doing this I laid hands upon everything Osta Abdallah required for the ordinary works in hand. I appropriated the paddle axle of one of the steamers, as I said I required this to be cut with eccentric
