"But it's like a dancing-floor or a parade-ground for soldiers!" cried Colin as, reaching the top of the hill, he looked across a stretch of upland plain at least half a mile across. There was not a blade of grass, not a twig of shrubbery of any kind, all had been beaten down and the bare ground was as smooth as though it had been

leveled off and rolled. Upon this bare plain, thousands of the holluschickie were playing, the most characteristic game seeming to be a voluntary march or dance, when the bachelors would roughly gather into lines or groups and lope along at exactly the same speed together for about fifty feet, stopping simultaneously for a few moments, and then going on again, as though obeying the commands of a drill-sergeant.

"They don't seem to play with each other much," commented Colin as the two walked among the holluschickie, who showed neither fear nor excitement, merely shuffling aside a foot or two to let them pass.

"They do in the water," the agent said. "Play 'King of the Castle' on a flat-topped rock for hours together. One seal pushes the other off the coveted post, only to be dislodged himself a minute after. And I have never once seen any sign of ill-humor. They never bite. They never injure one another. They never even growl angrily. It's hard to believe that their tempers can change so quickly when they reach the rookery."

"They seem to be of all ages and sizes," said Colin.
