"Cadets—staaaaaaaand to!"
There was a shuffle of feet as the boys rose as one.
"All the purple slips follow me," he roared and turned toward the door. The cadets with purple slips marched after him.
Lieutenant Saminsky stepped briskly to the front of the room.
"Cadets with orange slips will please come with me," he said casually, and another group of cadets left the room.
From the rear of the room Captain Strong snapped out an order.
"Blue slips will come with me!"
He turned smartly and followed the last of Lieutenant Saminsky's cadets out of the room.
Tom looked around. The room was nearly empty now. He looked over at Astro and saw his big friend slumped moodily over against his desk. Then, suddenly, he noticed Roger Manning. The arrogant cadet was not smiling any longer. He was staring straight ahead. Before him on the desk, Tom could see a green slip. So he had failed too, thought Tom grimly. It was poor solace for the misery he felt.
Dr. Dale stepped forward again.
