LOBLOLLY OB NOKTU CAROLINA PINE. 



Actual stumpage pricv which is offered, using as a basal diameter the 

 diameter breasthigh of the average sized tree on the tract. For ex- 

 ample: If board measure stumpage were worth $1.50 per thousand feet, 

 the volume which is given for the average tree in the board measure 



iinn should In- multiplied by 1.50. If the cordwood stumpage meas- 

 ured after peeling were worth 50 cents a cord, the value given of the 



rage sized tree which is under this head should 'be multiplied by 

 j-arisou of the two resultant figures will show in which form 

 the timber could be marketed most profitably. Cords of 128 cubic feet 

 with bark on can be converted to cords of 160 cubic feet with bark on 

 by deducting one-fifth from the value per cord of 128 feet. The table 

 is based on all trees in stands 6 inches and over in diameter breasthigh. 

 Cordwood is cut to 3 inches inside the bark at the top for small trees 

 and 6 inches for large trees. If knotty tops are not used the values of 

 the trees must be reduced about one-tenth.

8ILVICULTUBAL SYSTEMS OF CUTTING IN DIFFERENT TYPES. 



The widely different conditions under which loblolly pine grows re- 

 quire different methods of cutting in order to obtain the most thorough 

 restocking. At times, however, it is not possible to adopt what is re- 

 garded as the most suitable system of restocking on account of the 

 method of logging which is employed, and there must be a compromise 

 in order to meet the logging requirements. 



There are in common use three different methods of logging loblolly 

 pine. On wet land logging railroads are used with cable skidding, gen- 

 erally with overhead cable; or sometimes skidding is done by cable 

 dm-ot from the streams or canals dug for the purpose. On uplands log- 

 ping railroads are used, particularly on large tracts in .extensive opera- 

 tions with slack cable skidding or drag skidding. This is frequently
