and the poem destroyed. The third requisite which is also recommended should be observed in correspondence, is writing in chemical inks, that is, with such inks that it is impossible to read them without special adaptations. If a secret Party letter falls into the hands of the police written in invisible ink they must first of all guess that it is written in invisible ink; the open text of such letters must be made perfectly blameless, for example, a son is writing to his mother that he is alive and well and of the good things he wishes her. Not a word about revolution. The police must guess first of all that under this apparent innocent text there is a hidden text. Having discovered this secret the police tumble against the cipher. If they succeed in deciphering the cipher, they stumble up against a code and they have still to decipher that code. But all this takes time in the course of which the police can do nothing. If the police succeed in reading it in the course of two or three weeks, then by that time the Party organization has been able to cover up all the consequences of the question which was written about in the letter. What kind of invisible ink should be used? Invisible inks exist in a very great number. They can be bought in any chemist’s shop. Finally, comrades must use the latest inventions of chemistry in this direction. The simplest invisible ink which can be recommended and which can be found everywhere, is, for example, onion juice and pure water. 16. PLAN OF WORK OF THE PARTY COMMITTEE
