RECONNAISSANCE IN PHILIPPINES AND BORNEO 



375 



of at least some areas carrying stands heavy enough to warrant de- 

 velopment on a large scale. The detailed data thus acquired would 

 then be of immediate use when such areas were opened up, and, al- 

 though there were was the possibility of running unnecessarily detailed 

 surveys in areas which would eventually turn out to carry too low a 

 stand to make the area commercially valuable, this policy has been 

 adequately justified by results. The v/ork has now been under way 

 four years and, excluding explorations which have been of a prelim- 

 inary character, fifteen detailed surveys have been completed. Of 

 these, twelve have resulted in the location of commrecial stands easily 

 accessible from navigable rivers or harbors, the great bulk of the 

 timber lying within five miles of tide water. The total area covered 

 by these twelve surveys is 185,136 acres and the total estimated stand of 

 timber 333,889,000 cubic feet. The estimate has been based on 5,420 

 acres of valuation survey, or 2.92 per cent of the area covered by 

 the surveys, and the average stand per acre works out at 1,803 cubic 

 feet. The close relation of Bornean forests to those of the Philippines 

 is shown by the following comparative table, which gives the stand 

 per acre and percentages for the important Borneo species and for 

 identical, or closely related, species in the Philippines : 



The Philippine data for the above table were compiled from Fox- 

 worthy's resume of reconnaissance work done in the Philippines, two 

 pieces of work covering 2,225,000 acres being excluded because the
