"Well, I must say, this is a very unceremonious proceeding!" exclaimed the spectacled woman. "Pray, gentlemen, to what are we indebted for this honor?"

"Humph! I suppose it was an accident that the tower of this building was damaged, if not absolutely loosened at the foundations. You will have to pay the damages!" Then turning, and seeing about two score of young ladies behind her on the flat roof, each young lady eying with astonishment, not unmixed with admiration, the airship, the elderly one added: "Pupils! To your rooms at once! How dare you leave without permission?"
"Oh, Miss Perkman!" exclaimed a voice, at the sound of which Tom started. "Mayn't we see the airship? It will be useful in our natural philosophy study!"
