"If we're a Clan, we'll have to have a chief," said Jean, "and if the Chief bids us do anything, we'll just have to do it. That's the way it was in the real Rob Roy Clan. Father said so."

"Jock thought of it first. Let him be Chief," said Alan.

"No!" cried Jean promptly. "Are you thinking I'll put my head in a bag like that, and he my own brother? 'Deed, I'd never get a lick of work out of him on Saturday if I did! Na, na, lads! Whoever's Chief, it won't be Jock."

"Maybe you'd like to be the Chief yourself," retorted Jock, "but it's enough to be bossed by you at home! Besides, whoever heard of a girl being Chief, anyway?"

"Alan can be Chief," said Jean, and so the matter was settled.

"If I'm Chief," said Alan, "you'll all have to swear an oath of fealty to me."

"What's an oath of fealty?" Jock demanded suspiciously, and Jean added in a shocked voice, "Alan, you'd never be asking us to take the name of the Lord in vain!"

"It's not that kind of an oath," laughed Alan. "You just have to vow to obey the Chief in everything." Then an idea popped into his head. "In a real Clan they are all kinsmen, but here's Sandy, and he's neither Campbell nor McGregor. We'll have to make a blood brother of him before he can join."

"What's a blood brother? How do you make 'em?" asked Sandy.

"I'll show you," said Alan. He drew his knife from his pocket and while the other three watched him in breathless admiration, he made a little cut in his wrist and immediately passed the knife to Jock. "You do the same," he commanded.
