"I have given you the background to explain why I cannot handle the job, Mr. Reich. I am a 2nd Class Esper. I can telepath normal applicants rapidly and efficiently, but I cannot handle other Espers with the same speed and economy. All Espers are accustomed to using mind-blocks of varying effectiveness depending on their rating. It would take me one hour per 3rd for an efficient screening interview. It would take me three hours per 2nd. I could not possibly peep through the mind-block of a 1st. We must hire a 1st like Blonn for this work. The cost will be enormous, of course, but the necessity is urgent."
