For the second time in eight days, the Japanese Censorship Office in the Hardoon Building received a threatening letter from anti-Japanese terrousts on Saturday, the "Shanghai Mainichi" stated yesterday.
The letter, apparently written by the same person who sent the first one on March 4, warned the Japanese censorship authorities that powerful explosives would be hurled at the office unless work was suspended there. Early in February a bomb s tossed through the transom of the office door but it caused little damage.
