AMERICAN FORESTRY 



first time there is given the layman an 

 opportunity to learn how to know and to 

 appreciate them. 



The bulletin is published in two parts. 

 Part I gives a discussion of the general 

 type of vegetation with estimates of the 

 extent of the virgin forest, second growth 

 forest, grass lands and cultivated areas. 

 The forests themselves are discussed under 

 twelve separate types, five of which are 

 known as the Dipterocarp types, compris- 

 ing seventy-five per centum of the entire 

 area of the virgin forest and forming the 

 bulk of the timber manufactured in the 

 islands. The IMolave, Mangrove, Beach 

 and Mossy types are treated more briefly 

 and a discussion of their economic im- 

 portance is also included. 



Under the general heading of "Wood 

 Uses" is given a brief discussion of the 

 kinds of wood employed for different pur- 

 poses, such as house construction, piling, 

 wharf building, railroad ties, etc. "Lum- 

 bering in the Philippines" is another head- 

 ing. It contains a discussion of the mar- 

 ket, logging and milling operations, trans- 

 portation and labor. Dr. Whitford esti- 

 mates the annual cut of timber at eighty- 

 eight million board feet. The number of 

 steam sawmills has increased from thirty- 

 one in 1907 to sixty in present operation. 

 Under "Minor Forest Products" are dis- 

 cussed such subjects as fuel, resins, oil, 

 gutta percha, almaciga, rubber, etc. An 

 exceedingly valuable feature of the bulletin 

 is a number of diagrams showing from 

 just what sources all of these minor pro- 

 ducts are derived. For instance, on page 

 fifty-seven is a table showing the sources 

 of wild and cultivated gutta percha and 

 rubber, including all of the trees in the 

 islands from which these two products may 

 be obtained. There is also a chapter of 

 the bulletin devoted to a discussion of the 

 relation of the government to the forests 

 and their products; here is shown by dia- 

 gram how the government disposes of the 

 forest products and what the charges are. 

 How long-term exclusive licenses, or "con- 

 cessions," may be obtained is also fully 

 discussed. Part I is illustrated with 

 twenty-eight full page plates which add 

 greatly to its usefulness. 



Part II treats of the "Principal Forest 

 Trees." Non-technical descriptions are 

 given of one hundred and six trees which 

 include all of the principal timber species 

 whose lumber is of importance in the com- 

 mercial markets. Brief mention is made 

 of some two hundred and seventv-seven 

 other trees of the Islands that are found 

 in the forests or else are cultivated for 

 ornament or for fruit. This part of the 

 bulletin contains one hundred and three 

 illustrations showing the bark, leaf and 

 wood characteristics of the principal spe- 

 cies. 



This bulletin is not for free distribution, 

 but is sold at a price of |1.25 per copy.
