(e)Each Inspector of Excise is required to maintain a confidential note book, wherein all information relating to offence under the Excise and Opium laws etc., and the names of notorious smugglers, suspects, informers and spies residing or working within his charge should be noted. The officer will also enter in the confidential note book details of work done with informers and spies on every occasion and progress made towards the detection of a particular case or cases. Such note books will be open to inspection and scrutiny by his superior inspecting officers. When an officer is transferred from one station to another, he will make over the confidential note book to his successor or leave the same in a sealed cover to be opened and received by the latter.
