“Oh!” sounded the surprised five girls.

“You must have slept like a multi-millionaire on his sea-going yacht,” laughed Zan.

“I did, and without fear of going to the bottom by a torpedo from a submarine,” retorted Miss Miller.

“We have a wonderful roof on the back verandah—all decked and railed in,” remarked Jane, mentally picturing a row of tents on that desirable camp-site.

“I could use the rear porch that opens from our dining-room windows,” added Nita.

“We have a box-like porch on the second floor that has a back-stair going down from it. It is screened in and can be used for a sleeping-place, I s’pose,” murmured Elena.

“Our flat-house was built soon after Noah landed so we have no sleeping-porch, but I might hang a cot from the fire-escape—until the police make me take it down,” ventured Hilda, with a thoughtful manner.

The others shouted with merriment at the idea of big muscular Hilda swinging from a fire-escape over the street.

“I have my lodging all planned out,” now said Zan. “I shall utilise that square of side-piazza roof over the entrance to Dad’s office. It has a two-foot high coping about it and that makes it perfectly safe for me in the dark. I can use a screen, too, to hide the cot from the street.”

“You girls have all caught my last-night’s idea so suddenly that I haven’t had an opportunity to continue explaining,” interrupted Miss Miller.
