"Get the map we drew the other night, and we'll try and make it plainer. Now, if you can imagine the moon making a silver streak along the heavens, it would pass along such a route that the following fixed stars would be in its path. Note them carefully, as follows: Hamel, Aldebaran, Pollux, Regulus, Spica, Antares, Arkat, Fomelhaut, and Markab."

"But how can we distinguish one of the fixed stars from the others? That is a matter which has always puzzled me."

"Because of the company it keeps. Isn't that like we judge people?"

"I don't understand what you mean."

"Each fixed star is set in the heavens with certain others stars arranged about it in such a way that it cannot be mistaken."

Angel's antics now attracted the attention of the company. He had been on the floor while the music was being performed, but disappeared shortly afterwards. He had his gun, and dodged from one chair to the next, and sighted his gun, and bounded away, as though attacking and running from an imaginary enemy.

This exhibition was a perfect mimicry of the boys' attitude during the previous week. The comical manner in which he fought and eluded the enemy brought out roars of laughter, but this did not affect him in the least; he sprang to the rafters, and began to chatter in imitation of the way he had warned the boys, and then sprang down and hid behind a chair.

But the acme of his exhibition was reached when he mounted the table and simulated the rocking motion of the wagon crossing the stream. George simply hugged him, and Angel joined in the laughter.

But the boys wanted to know about John and Chief. John was there to welcome their return, and Chief came up soon after, and held out a welcoming hand, as he had seen the others do. Of course, he had no idea what the party went away for, nor did he comprehend the failure to bring the boat back. His education had not yet advanced to such a state as would have made an explanation of that kind understandable.

But John seemed to realize the story, and his eyes often glistened as they had not done before. On all these occasions the Professor was ever on the alert to notice his symptoms.
