Ty, Einstein, and Kath Two were fitted with hinged collars of bent steel. When these were closed around the neck, loops in the free ends came into alignment so that a chain could be run through them, locking them shut while stringing all the captives together. At one end, the chain was terminated by an ancient padlock that was too large to pass through the loops on Kath Two’s collar. The other end was then affixed, by means of a bolt, to a large wooden stake that an especially burly Digger had pounded into the ground with a stone-headed maul that looked like a miniature Thor.
