"Oh, an airship!" exclaimed one. "How lovely! We thought it was an
earthquake, and we were afraid to come up for quite a while. But an
airship! I've always wanted to see one, and now I have an opportunity.
It will be just the thing for my physical geography and natural
history class. Young ladies, attention, and I will explain certain
things to you."

"Miss Delafield, do you understand enough about an airship to lecture
on one?" asked Miss Perkman smartly.

"Enough so that my class may benefit," answered the other teacher, who
was quite pretty.

"Ahem! That is sufficient, and a different matter," conceded Miss
Perkman. "Young ladies, give your undivided attention to Miss
Delafield, and I trust you will profit by what she tells you.
Meanwhile I wish to have some conversation concerning damages with the
persons who so unceremoniously visited us. It is a shame that the
pupils of the Rocksmond Seminary should be disturbed at their studies.
Sir, I wish to talk with you," and the principal pointed a long,
straight finger at Mr. Sharp.

"Young ladies, attention!" called Miss Delafield. "You will observe
the large red body at the top, that is-"

"I'd rather have you explain it," whispered Mary Nestor to Tom. "Come
on, slip around to the other side. May I bring a few of my friends
with me? I can't bear Miss Delafield. She thinks she knows everything.
She won't see us if we slip around."
