ence at the
first sign of inactivity.

"We must go right back and get permission from Mr. Ferris to locate our
camp somewhere near the Graham home," said Katherine. "We ought to get
our tents pitched just as soon as possible, and we mustn't run any risk
of not being able to find Mr. Ferris today."

"Don't you think it would help to allay their suspicions if we all
remained here a while and looked around as if interested in the scenery
just as tourists?" Azalia Atwood suggested.

"No, I don't," Katherine replied quickly. "Either that man Langford
suspects us or he doesn't. If he suspects us, he has grounds for his
suspicion, and any such attempt to throw him off the track would result
in failure. I think we had better assume that he knows what we are up to
and act accordingly, without appearing to admit it."

"But won't they try to cover up the evidence that we are after?"
Julietta Hyde reasoned.

"Of course they will," Katherine answered.

"That will be one of the most interesting features of this adventure,"
said Helen Nash, who already had a reputation wider than the Camp Fire
circle for natural shrewdness. "When they begin to do that, we'll have
some great fun."

"Can't you point out from the lake the place or places where you think
it would be well for us to locate our camp?" Miss Ladd inquired,
addressing Hazel and Katherine.

"You can get a pretty good view of it right from here," Hazel replied.
"It's right up the shore between those two cottages which are about the
same distance up from the water and have similar paths and flights of
steps running down to their boat landings. Between those two places is a
stretch of timberland that doesn't seem to be used by anybody in
particular. We didn't explore it because we didn't have time, but it
surely must contain some good camping places. We saw several small open
spots near the road that could be used if nothing better is found. We
must make a thorough inspection, of course, before we select a site, but
that won't take long and can be done when we bring our outfit up here."

"We ought to take a run in the boat along the shore and see if we can't
find a good landing place," Katherine suggested. "Wouldn't it be
delightful if we could find a suitable place on the side of that hill
and overlooking the lake? Let's take enough time for that."

"It's a good idea," said Miss Ladd warmly. "Let's do that at once and
then run back to Twin Lakes. But remember, girls, d
