Coast Survey Map of the region of the Friendly Islands, Southern Pacific Ocean, showing the deep trenches dugout in the sea bottom between Samoa and New 

 Zealand. Here the Earthquakes are developing a great mountain range on the western side of the Pacific, analogous to the Andes on the East. In the contour lines 4 points 

 denote a depth of 4000 fathoms, 3 points 3000 fathoms, the continuous dashes 2000 fathoms, and the continuous line near shore 100 fathoms.
