Temptress of Planet Delight

A sears-monkey flew to vend his wares
On a planet strangely groomed.
Lo and behold, he lost all his cares
As the genetic experiment bloomed.
When the alarm signalled the first whiff of the atmosphere of the next planet on his route, Herl Hofner stopped chinning by his strapping six-foot self and left the little gym. Slipping into the swivel chair at the desk he clipped the pile of loose papers into an empty niche at the side of the desk, spun the chair around to the instrument panel of the Krylla . Dialing with his left hand, he swept the bank for incoming signals while his right hand adjusted the microphone frequencies.
Class M-for-Mary ship requesting permission to land. Do you have automatic beam landing device? Class M-for-Mary ship requesting permission to land. Do you have automatic beam landing? His dial pointer swept back and forth.
Come in, class M-for-Mary.
Herl's left hand moved to the autobeam switch. What band for M-for-Mary landing? What band for M-for-Mary landing?
Come in on seventy-three point eight, M-for-Mary. Come in on seventy-three point eight, M-for-Mary.
Herl's left hand now centered the needle neatly on the appropriate setting as his right pressed the stud for extending the wings with their powerful atmosphere motors; and he sank back into the chair cushions with a relieved sigh. This was still a civilized planet. He'd be able to get back maybe a month sooner than he'd expected after the most recent setback. Forty years, he frowned, was too long between visits from Galactic Central, even if Central had no responsibility for autonomous groupings. A lot could happen in forty years on these isolated planets. The unprecedented mutation leaving half the population deaf and dumb had made the last call a long and tedious one. But by the signs so far, this planet was still ticking along satisfactorily with radio and radar and standard language, a space-port and all the comforts of civilization.
The speaker hummed into activity. Please state vessel name, registration, number of crew, destination, and nature of business, M-for-Mary entering on band seventy-three point eight.
