ve us!" cried Jean, clasping her
hands in admiration. "What will you do with it all?"

"I'll show you!" said Alan. "Where's Jock?"

"He and Sandy have gone up the burn, exploring," said Jean. "They
said you were to follow, and if you didn't find them, keep
whistling the pewit's call three times till they answered you."

"What is the pewit's call?" asked Alan.

"Michty me!" said Jean. "Think of not knowing that!" She pursed
up her lips and whistled "Pee-wit, pee-wit, pee-wit."

"You see, we don't have them in London;" Alan apologetically
explained, "unless it's in the Zoo; but I say, Jean, aren't you
coming, too? You're as good as a boy any day. Come along!"

"All right," said Jean. "I wanted to dreadfully. I'll get a
basket for the lunch." She went to the closet and brought out a
basket which her father had made out of split willow twigs,
packed the lunch in it, and off they started.

They passed the place where the fish-bones were buried, and the
spot where Alan had fallen into the water the day before, and
then plunged into the deep pine forest which filled the glen and
covered the mountain-sides. The pine-needles lay thick on the
ground, and above them the pine boughs waved in the breeze,
making a soft sighing sound, "like a giant breathing," Jean said.
The silence deepened as they went farther and farther into the
woods. There was only the purring of the water, the occasional
snapping of a twig, or the lonely cry of a bird to break the
stillness. It was dark, too, except where the sunshine, breaking
through the thick branches overhead, made spots of golden light
upon the pine-needles.

"It's almost solemn; isn't it?" said Jean to Alan in a hushed
voice. "I was never so far in the woods before."

"I wonder which side of the burn the boys went. If we should
take the wrong side, we might not find them," said Alan.

"Let's whistle," said Jean. She puckered her lips and gave the
pewit call, but there was no answer.

"Perhaps they didn't hear it because the burn makes such a noise.
It keeps growing louder and louder," said Alan.

Whistling and listening for an answer at every few steps, they
climbed over rocks and fallen trees, keeping as close as possible
to the stream, until suddenly they found themselves gazing up at
a beautiful waterfall which came gushing from a pile of giant
rocks reaching up among the topmost boughs of the pines.

"Oh, it's bonny! but how shall we get up?" cried Jean.

"We must j
