Crop-Dusting Manual Found, Time Reports

The FBI in Washington said it had not seen the report and had no comment on it.

The magazine said its issue due out Monday would disclose that a manual for crop-dusting equipment had been found during a search of the suspected hide-outs of some of those believed responsible for the attacks.
