“What do you see?” Doris demanded.
“It looks like a cracking big cave.”
Somewhat reassured, the girls wormed their way through the opening and Dave brought up the rear. It was pitch dark inside, but the beam of Marshmallow’s light furnished a faint illumination.
“Follow me,” Marshmallow commanded.
He led the way deeper into the cavern. The cave consisted of two chambers, and as the four friends entered the second room Marshmallow flashed his light over the ceiling. They saw strange formations resembling icicles hanging from above.
“Stalactites!” Doris exclaimed.
“Aren’t they odd?” Kitty cried. “What causes them anyway?”
“I’ve read that stalactites are caused by the dripping of water which contains carbonate of lime,” Doris explained.
“Folks, I guess we’ve seen all the sights,” Marshmallow, who had gone on a short way ahead, announced. “It isn’t as large a cave as I thought.”
“No buried treasure, either,” Kitty murmured in disappointment. “Still, the stalactites are interesting. Imagine living this close and not knowing anything about them.”
