the full length of the log in estimating the length for the purpose 

 of determining its cubic contents. 



VI. The volume of pieces of timber which come to a point or 

 nearly to a point at one end, will be determined by multiplying 

 the square of the average diameter by eight-tenths and the result 

 by the length; one-half of the diameter of the large end will be 

 considered the average diameter. 



VII. Pieces of wood more than one and one-half meters in 

 length and fifteen centimeters in diameter will be designated 

 as timber. 



VIII. In determining the Goverimient charges on minor forest 

 products other than firewood — i. e., charcoal (carbon vegetal), 

 gums (gomas and gutapercha), resins (almaciga and. breas), 

 wood oils ( balao ) , dyewood ( sibucao, maderas tintoreas ) , dye- 

 bark (uigue), and tanbark ( cascalote ) ^the actual value at the 

 market nearest the forest where the product is gathered will 

 be taken as the "actual market value." The following weights 

 and measures will be used in manifesting such minor forest 

 products : 



The metric quintal for gums, resins, and dyewoods. 



The liter for wood oils. 



The cubic meter for charcoal. 



Tanbark and dyebark will be estimated by the thousand pieces, 

 provided that where the pieces are not of uniform size or are 

 so small as to make their counting burdensome, the metric 

 quintal may be used. 



GENERAL PROVISIONS RELA.TIVB TO LICENSES. 



IX. (a) Licenses issued under the provisions of The Forest 

 Act will entitle the holders for certain fixed periods of time to 

 enter upon definite tracts of public land and obtain therefrom, 

 under conditions stated in the licenses, the material designated 

 therein, but will not convey any further right or authority. 



( b ) Licenses to cut, collect, and remove timber, firewood, gums, 

 resins, or other forest products from public forests and forest 

 reserves will, with the approval of the Secretary of the Interior, 

 be granted by the Chief of the Bureau of Forestry: Provided, 

 That special authority to grant licenses for small amounts of 

 forest products may be given by the Chief of the Bureau of 

 Forestry to foresters, assistant foresters, inspectors, and assistant 

 inspectors. They will be of the following four general classes: 



( 1 ) License agreements, which will provide for the exclusive 

 privilege of cutting, collecting, and removing forest products for 

 a period not to exceed twenty years over areas of public forest 

 larger than those granted in ordinary licenses. 



These agreements will provide certain conditions, limitations, 

 and restrictions, including a minimum amount of timber to be 

 cut during the first year, and methods of cutting and hauling 

 the same to prevent undue injury to the forest, responsibility 

 of agents and employees, and the charges to be collected on forest 

 products. 



(2) Miners' licenses, which will provide for the cutting, collect- 

 ing, and removing of timber from the public forests or forest 

 reserves for use in developing the mines mentioned in the licenses. 

 The timber so cut to be paid for at one-half the ordinary Govern- 

 ment charges on such timber.
