FROM DIKOBRAZ NO. 21 -- 23 MAY 1968Josef Pavel, Minister: "What keeps growing here?" Pavel was the popular Minister of the Interior during the Prague Spring. The "signs" in his garden all refer to government monitoring of private communications: "When will censorship of telegrams cease?", "What about the jamming [of foreign radio broadcasts]?" "Bugging continues," "Invisible ears and eyes," "May I speak to comrade Bretschneider?" -- a reference to Bretschneider, the imperial secret policeman in Jaroslav Hasek's classic novel The Good Soldier Svejk, who hangs around taverns trying to provoke patrons into making treasonous statements against the Austro-Hungarian Emperor.
