2. GEOGRAPHY AND GEOLOGY 



By F. A. Dalburg 



Situation. — The San Jose Estate is situated in the south- 

 western part of Mindoro and on the low plain at the foot of the 

 western cordillera system. Mangarin formerly was the principal 

 place of habitation, but at present the new town of San Jose 

 has been built near the center of the estate. San Jose is sur- 

 rounded by lowlands which formerly had only a vegetation of 

 talahib and buri palms, but is now devoted to the cultivation of 

 sugar cane. (Fig. 1.)
