The task of finding a new keeper fell to the United States consul living in Panama, and this task was no small one: first, because it was absolutely necessary to find the man within twelve hours; second, the man must be unusually conscientious,—it was not possible, of course, to take the first comer at random; finally, there was an utter lack of candidates.

He cannot leave his rocky island except on Sundays.
