he shall mspect thoroughly each sheet and Descriptive Report, and in a general way the 

 accompanying records. Any deficiency must be fully explained. All results of field 

 work shall be forwarded to a Processing Office or to the Washington Office as soon as 

 practicable after the completion of the field work and, unless otherwise authorized, 

 before the beginning of another project or another season's work.
