He was back shortly with two sticks of wood one about a foot long and an inch or more thick while the other was nearly four feet long and about three times as thick.
"Here we are," he said as he handed the small piece to Jack. "Now, you hold that against one corner and I'll see what I can do."
Jack did as directed and Bob began to hammer the end of the stick with his club, gently at first and then harder as the frame showed no sign of yielding.
"Guess they must have used spikes," he said as he paused to examine the frame after he had struck thirty or more blows.
"Mebby better try other one," the Indian suggested.
"Not a bad idea," Bob agreed. "Come on, Jack, perhaps that one isn't nailed so hard."
"I'm going to get in there if I have to break the glass," Jack declared as he followed the others around to the other side.
"I hope it won't be necessary."
"She's giving a bit," Jack shouted after Bob had been hammering away for about five minutes.
"Good."
