PT: A message about nitroglycerin and President Bush found scrawled in the hold of a cargo ship just in from Guatemala shut down a Southern California deep-water port for several hours Monday, but federal investigators found no explosives. The harbor in Ventura County was closed just before noon after a dockworker discovered the writing in the hold of the ship, which was carrying a load of bananas, said Will Berg, the port’s marketing director.

Federal authorities said it was written in English and read: �Nitro + glycerin my gift for G. W. Bush and his Jewish gang.�

The message, scrawled in marker on a metal pillar within the ship, was being investigated by the FBI, Secret Service and local officials.

FBI spokeswoman Laura Eimiller said no nitroglycerine or other explosives were found during a thorough search.

�No threat exists,� she said.

Divers inspected surrounding waters.

About 20 people were evacuated from the 30,000-ton refrigerated vessel, identified as the Wild Lotus which arrived from Quetzal in Guatemala on Sunday evening,
