Penguin Breeding Grounds.

These birds often occupy acres for their breeding ground, which is laid out and leveled and divided into squares, as nicely as if done by a surveyor. They march between the compartments as accurately as soldiers on parade, and somewhat resembling them from a distance, or, according to another similitude which has been used, looking like bands of little children in white aprons. Bennett describes one breeding ground on Macquarie Island as covering thirty or forty acres, and, to give some notion of the multitudes, speaks of 30,000 or 40,000 birds as continually landing, and as many putting to sea.
