front signals were special at the curves and flashed green just as you neared the semaphore."
"Absurd!" exclaimed Ralph.
"That's what the conductor says, too," said Clark. "He told the station agent so. They nearly had a fight. 'Color blind!' he told the station agent and challenged him to find green lights on No. 999 if he could. The station man was awfully rattled and worried. He says he knew a special was on the list, but being new to this part of the road he acted on Rule 23 when he saw the green lights. He sticks to that, says that he will positively swear to it. He says he knows some one will be slated, but it won't be him."
"What does the conductor say?" inquired Ralph.
"He says Rule 23 doesn't apply, as the white lights prove. If there was any trickery or any mistake, then it's up to the fireman, not to the engineer."

The torch he carried illuminated a pale, twitching face. His eyes were filled with a craven fear, and Ralph tried to imagine what was passing through his mind.
