The sides of the earth fell away sharply, down, down. Betty shouted, and the empty echo of her voice came back to her.
"The ground"s so shaly and crumbly," she said thoughtfully, "that it would be impossible to let a man down with a rope--the earth would cave in and bury him."
"I think I see a diamond," reported Libbie. "Don"t you see something glittering down there?"
"Can"t even see the bottom," said Bobby curtly. "Much less a diamond. Oh, girls, to think of those valuables at the bottom of a chasm like this and none of us able to think up a way to get "em out."
"Well, lots of people have tried," said Alice reasonably. "If grown-up men couldn"t salvage "em for grandma, I guess it"s nothing to our discredit that we can"t get them."
"We might push Libbie in," suggested Bobby wickedly. "Then she could tell us how deep it is."
This had the effect of sending Libbie scurrying away from the dangerous place, and the others followed her more slowly to resume the search for nuts.
"I wish we could think of a way, Norma, dear," said Betty.
"Oh, I don"t care--not so very much," answered Norma bravely. But then she sighed deeply.
CHAPTER XVII
CAUGHT IN THE STORM
The Shadyside gymnasium was equipped with a fine pool, and it was the school"s boast that every girl learned to swim during her first term.
Perhaps the proximity of the lake and the lure of the small fleet of canoes and rowboats tied up at the wharf had something to do with the success of the swimming cla.s.ses. No girl who could not swim was permitted on the lake, alone or with a companion.
Betty and her chums awaited their final tests eagerly--so excited the last day or two they could scarcely keep their minds on their books or sit in patience through a recitation--and pa.s.sed them with flying colors.
Constance Howard was an excellent swimmer, and it was the sight of her paddling gracefully about the lake on sunny Sat.u.r.day afternoons that spurred the seven who could not swim on to greater effort.
"Come on," cried Betty gaily, taking the gymnasium steps two at a time.
"Come, girls--this afternoon we go rowing. I"ve my "stiffcut," as Mr.
Peabody used to call it, and we"ve all pa.s.sed. Oh, it"s cloudy!"
She looked at the sky disappointedly. When they had gone into the pool an hour before the sun had been shining brightly, but now the gray clouds were thick overhead and the air was chilly.
"Who cares for the weather?" said Bobby scornfully. "Guess it will take more than a little rain to stop me! I"ve been crazy to take a row-boat out for three weeks."
"Perhaps it will clear," contributed the optimistic Louise.
But after lunch the sky was still overcast.
"Don"t be silly--it won"t rain," urged Bobby, as her chums demurred.
"Next Sat.u.r.day it may be too cold. Oh, come on, girls."
Thus incited, they went down to the wharf and made their choice of boats.
Norma and Alice wanted to take out a canoe, and they offered to paddle for Libbie, who seemed disinclined to exercise. Betty had wondered once or twice if the girl were ill, for she seemed very nervous, jumped if a door slammed or some one spoke to her suddenly, and in the morning looked as if she had not slept well.
Betty and Bobby selected a flat-bottomed row-boat and for pa.s.senger they took Frances, who offered to help row if they became tired.
Louise and Constance chose another canoe.
They headed north, and once out in the center of the lake, paddled and rowed steadily. Betty"s rowing experience was limited, but Bobby was proud of her "stroke," and soon taught her chum the secret of handling the oars.
"Ship ahoy!" shouted Bobby presently.
Libbie jumped and looked ahead anxiously.
"It"s only the boys," she said dully.
An eight-oared rowing sh.e.l.l shot down to them, and the freckled-faced c.o.xswain, Gilbert Lane, one of the boys the girls had met at Bob and Tommy"s "party," grinned cheerfully.
"Where you going?" he asked, resting a friendly hand on the rowboat"s rim.
Bobby described an arc with her oar that incidentally showered the questioner with shining water drops.
"We"re out for adventure," she answered airily.
"Just got our swimming certificates to-day," volunteered Betty.
Bob flashed her a congratulatory smile.
"Race you to the end of the lake?" suggested Tommy Tucker.
Bobby regarded him with magnificent scorn.
"As if eight of you couldn"t beat two!" she said significantly. "I never heard such talk! Why you"d have a walk!" she added.
The boys shouted with laughter.
"You"re a poet, Bobby," declared Tommy. "Tennyson had nothing on you--had he, Libbie?"
Libbie turned her dark eyes on him and frowned a little.
"I wasn"t listening," she said indifferently.
"Well, anyway, row up to the end of the lake, will you?" suggested Gilbert. "With drill night ahead of us, we want a little brightness to remember the day by."
Canoes, rowboat and sh.e.l.l swept on up the lake, and when the scrubby pines that bordered the narrow peak of the north sh.o.r.e were in sight, Bobby glanced back over her shoulder at Betty.
"You"re spattering me," she complained.
"I thinks it"s beginning to rain," said Betty mildly, and even as she spoke, Louise called to them:
"Girls, it"s beginning to pour!"
A sudden blast of wind struck them, blowing the rain against their backs.
