From the diary of Samuel Pepys (1663-1703)
This night my boy Wainman, as I was in my chamber, [I] overheard him let off some Gunpowder; and hearing my wife chide him below for it, and a noise made, I call him up and find that it was powder that he had put in his pocket, and a mach carelessely with it, thinking that it was out; and so the match did give fire to the powder and had burned his side and his hand, that he put into his pocket to put out the fire. -- Pepys' Diary, 2 Nov. 1661
