A most interesting supplement to the report of the Rowlatt Commission is a museum that has just been opened at the Police training school in Calcutta. Here are gathered together various exhibits that have been produced from time to time in courts, when men have been put on their trial for assassination, dacoity or other crimes. Bombs of many types are displayed, the first being highly dangerous book bomb that was sent to Mr. Kingsford by the members of Maniktala Garden conspiracy in 1907. Progress of anarchists in the art of bomb making can be traced in these interesting exhibits from the time when they experimented with cocoanuts, brass and copper to the dangerous type of bomb made with the aid of a common cigarette tin.
