He invented an engine for nipping lead shot, used for years in the royal laboratory, but for which an impostor and spy, named De Haine, received a reward of 500_l._ While filling the office of inspector of ordnance stores, he made various improvements in the mechanical and intrenching tools. He also detected many extraordinary frauds in the deliveries made by contractors. In one attempted imposition only, he saved the Government 2000_l._ He designed and constructed a life-ladder, which was frequently used with success at fires, and an ingenious mortar-mill which occasioned a great saving of expense to the department. At Chatham he invented many useful tools, implements, and apparatus, and his services were repeatedly acknowledged in the order books of the establishment. ----- 1812.

Major Pasley, R.E., on his appointment to the Plymouth station, occasionally practised his company in sapping and mining. He was one of those officers who took pains to improve the military appearance and efficiency of his men, and to make them useful either for home or foreign employment. He is believed to have been the first officer who represented the advantage of training the corps in the construction of military field-works.
