Scribner rule will be used for lagging and saw logs, and each 

 stick must be scaled and stamped separately. Hasty methods 

 of averaging different sizes will not be allowed. 



Railway ties are rated as follows: 



8-foot ties, 33i feet B. M. each. 



6-foot ties, 25 feet B. M. each. 



Posts, poles, and piles are measured by linear feet, the valu- 

 ation per foot increasing with the length and size of the stick. 



Shake and shingle- bolt material is measured by the cord. 



Square material is scaled like lumber, at its actual contents 

 B. M., maldng no allowance for saw kerf. Thus, an 8 by 12 

 inch 16-foot stick contains 128 feet B. M. 



Where green logs 8 inches and over in diameter are made 

 into cord wood, they are paid for as saw timber at the rate of 

 2 cords to the 1,000 feet B. M. 



All wood and timber must be scaled before removal from 

 the tract or landing, and every stick of timber and pile of 

 wood must be stamped with the " U. S." marking hammer. 



In cases of "free use" of timber the same precautions are 

 necessary as in the cases of sale of timber. 



Every application, whether approved by the supervisor or 

 by the Department, should be accompanied by a definite report 

 giving sufficient information to enable a proper decision. 

 The blank form provided for such report (see p. 62) should 

 be followed. 



The sowing of tree seeds has been carried on experimentally 

 in some of the reserves in California. There are many places 

 where an expenditure of money for that purpose may, at some 

 future time, be warranted. Generally, however, the great 

 extent of the reserve forests, the limited market, the uncer- 

 tainty of success in the very places where this method is most 

 called for, indicate a conservative attitude, and not until a far 

 more liberal appropriation of money is assured is there reason 

 for introducing seeding and planting methods on more than an 

 experimental scale.
