is strongly marked on all sides except 

 on the southwest, where a small stream 

 breaks through and drains the lake into 

 China Sea. An active volcano rises as 

 an island from the middle of the lake to 

 the height of a thousand feet. 



In the southern part of central Luzon 

 are numerous volcanoes, most of them 

 extinct. Southeastern Luzon has a very 

 irregular outline and contains a number 

 of short ranges and mountains of no 

 great height. The greater elevations 

 of this part of the island consist of active 

 or extinct volcanoes. Of the former 

 the most notable is the beautiful and 

 symmetrical cone of Mayon, which rises 

 from the shores of Albay Gulf to the 

 height of 8,000 feet. This has been in 



eruption several times within the his- 

 toric period and has done great damage 

 to native towns and villages situated 

 about its base. Another fine volcano, 

 not now active, is Mount Isarog, which 

 rises over 6,000 feet above the town of 

 Nueva Caceras. 



The island of Mindoro is little known 

 except along the coast, as settlement 

 has not penetrated the interior and few 

 explorers have been far inland. It was 

 crossed last spring at its widest part by 

 Captain Offley, the governor of the 

 province. The main topographic feat- 

 ure of the island is a range of mountains 

 running from the northwest corner 

 southeastward and then southward to 

 the southern point, with broad spurs.
