"I have nothin' much, but an albuminoid rib."
"What kind of a rib?"
"That's what you call it. If it isn't that it's alkali."
"What kind of a rib is an alkali rib?" asked John.
"Why, it's one of those things that's about as light as paper. Here, I'll show it to you," he added as he drew from his inner pocket a metal rib, which he at once handed to Fred.
"That looks like aluminum to me," said Fred quickly.
"That's just what I said," retorted Sam. "I thought I'd bring it along in case anything happened. I'll have some feet and hands comin' later."
"What for?" laughed Fred.
"What do you s'pose they're for? They're for you to wear."
"If you had brought along a head," said Grant solemnly, "it might have been a good thing. I have known Fred to lose his several times."
