Having disposed of all there was to eat and drink, the two lads walked around the little room to keep warm. Then Dave went at the door again, examining the lock with great care, and feeling of the hinges.
"Well, I declare!" he cried, almost joyfully.
"What now, Dave?"
"This door has hinges that set into this room and are held together by little rods running from the top to the bottom of each hinge. If we can take out the two rods, I am almost certain we can open the door from the hinge side!"
This was interesting news, and Phil came forward to aid Dave in removing the tiny rod which held the two parts of each hinge together. It was no easy task, for the rods were somewhat rusted, but at last both were removed, and then the boys felt the door give way at that point.
Now that they could get out, Phil wanted to know what was to be done next.
