20 COOPERATIVE PROJECT 



(5) To determine the value of beveling the tops of fence 

 posts in a dry climate. 



MATERIAL. The material will consist of sound fire-killed 

 posts approximately 7~ft. long and with 5-in tops. They will be 

 cut on the Colorado National Forest near Ward, and shipped to the 

 plant at Fort Collins on Government bill of lading. They will con- 

 sist of approximately the following number by species : 



120 Lodgepole pine. 



1 20 Engelmann spruce. 

 50 Alpine fir. 



The cost of the posts will be a little more than twenty cents 

 apiece at the plant (10 cents apiece for cutting and delivering on 

 car at Ward, and from 10 to 12 cents for freight). 



The preservative will be furnished by the College and also any 

 labor necessary in treating the posts. 



METHODS 



DIVISION OF MATERIAL. The material will be carefully in- 

 spected at the plant and numbered with brass tags, and in addition 

 stamped with steel dies. A card form will be numbered to corre- 

 spond with each post and its complete history will be kept on that 

 card which will be filed at the State Forester's office, and consti- 

 tute the permanent record for the Agricultural College. The For- 

 est Service will keep its records on the standard forms for experi- 

 mental post records. 



One-half of the material for each type of treatment will be 

 beveled in order that the value of this practice in a dry climate may 

 be determined. 



The material will be divided as follows for treatment :
