He jumped into the water without further argument and soon they could dimly see him feeling his way along the edge of the cave. It seemed a terribly long time before he came back.
"Haven't found it yet," he said with an attempt at cheer. "It seems as if it ought to be easy enough to find a two foot opening but the top shelves down pretty sharp just there and the opening is now probably five or six feet from the surface. It's mighty discouraging to swim around under there and not find anything. I must rest up a bit."
"Why are you putting that light out, Chick-chick?" asked Apple.
"We c'n see jest's well with one as two, an' I've an idea we may need it wuss later on," replied Chick-chick, significantly.
"You're not getting scared, Chick-chick?" said Glen.
"No, I'm not gettin' scared. I'm just tryin' to use me thinker a bit. We got a boy here that may need 'tention. Won't do to be without light. You fellers got any matches?"
"Yes, I have some," said Apple. "I've kept 'em dry, too."
"All right, then. If Brick has to quit experimentin' in the water without findin' anything, we'll put out t'other light, too, an' just use 'em when we need 'em. This water's goin' to go down sooner or later, but while we have to wait a light when we need it will be awfully handy."
"I'm not through, yet," said Glen. "As soon as I find that opening I'll run to camp and get a rope, and we'll have you fellows out in no time. I've got marks outside to show me how to get back in all right."
Glen stayed away longer the next time, but he came back, shivering and exhausted.
