it lies near the middle of the South Pacific (Lat 27° 10' S ; Lon 109° 26' W.) ; it originated as a volcano, without connection with other land it has an area of about thirty-four square miles ; it possesses ; and mountains (to 1700 feet), and it is covered with vegesense of disappointment comes upon one when in the course of his investigations he realizes how much the island lacks age, that its birth plains, hills, tation A has been too recent for the evolution of species and varieties in a fauna of its own, when he decides that what is possessed it has borrowed in times not very remote and that he must direct his attention to the route by which it was brought Possibly more than one start was made by flora and fauna to be destroyed by later activity of the expiring volcano ;
