"Not much of a door yard. Where's the garden?" wondered Stacy, looking about him curiously.
The entrance to the cave dwelling was blocked by a huge boulder, that completely filled the opening. How it had been gotten there none could say. The only possible explanation was that the boulder had been found on the shelf and applied to the purpose of protecting the cave dwellers' home.
"Now we're here, we can't get in," grumbled Ned.
"Nothing is impossible," answered Kris Kringle.
"Except one thing."
"What's that, Master Ned?"
"To hammer the least little bit of sense into the head of my friend, Chunky Brown."
"You don't have to, that's why," retorted Stacy quickly. "It has all the sense it'll hold, now."
"I guess that will be about all for you, Ned," laughed Walter. "At least, Chunky didn't foul the dinner table when he jumped it."
The guide, in the meantime, was experimenting with the boulder, inserting a pike pole here and there in an effort to move the big stone. It remained in place as solidly as if it had grown there.
