As well as they were able, the two boys gazed around them. The hole was irregular in form, but about fifteen feet in diameter. One side was of rough rocks and the other dirt and tree roots. At the top the treacherous bushes overhung all sides of the opening, partly concealing the yawning pit below.
"The rain is coming in pretty lively," was Sam's comment, presently. "I wonder if there is any danger of this hole filling up with water."
"I don't think so, but if it does we can swim out."
"Or get drowned."
"Now who is getting blue?" demanded Tom.
To keep out of the worst of the rain Sam leaned against one of the sides of the hole. He felt it give beneath his weight and before he could save himself he went down into another hole, and Tom came after him.
The boys were scared and both cried out lustily. They did not fall far, however—in fact, they rather rolled, for the second opening was on a slant of forty-five degrees. They brought up against something soft, but this time it was not a bank of decayed leaves.
"Sam! And Tom!"
"Dick!"
"Where did you come from?"
"How did you get here?"
