TRACT NO. 13. 



Tract No. 13 contained 20 acres of practically level pasture land 

 having a sandy, and in places a gravelly, surface soil. The subsoil 



was generally below 

 root depth. This 

 land had been logged 

 25 years before. 

 There were no logs 

 or underbrush. The 

 outfit used was a tri- 

 pod stump puller. 



Stumps to the 

 number of 1,293 were 

 pulled, piled, and 

 burned at a contract 

 price of $500, or 38.7 

 cents per stump. By 

 means of the tripod 

 piler shown in figure 

 10 all these stumps 

 were put into four piles. The stumps were pulled in November, 1912. 

 The sizes of 98 white-pine stumps selected at random and meas- 

 ured on this tract were as follows: 12-inch, 6; 14-inch, 8; 16-inch, 

 8; 18-inch, 5; 20-inch, 10; 22-inch, 16; 24-inch, 16; 26-inch, 11; 

 28-inch, 5; 30-inch, 8; 32-inch, 2; 34-inch, 1; 38-inch, 2. The 

 average diameter was 23.2 inches. 



Several other owners in this neighborhood had contracted to have 

 stumps pulled, cleaned, and tipped for 25 cents each. The general 

 clearing conditions on these contracts were the same as for tract 

 No. 10. 



TRACT NO. 14. 



Tract No. 14 contained 7.4 acres of very gently rolling pasture 

 land, having a loose, sandy-loam soil. The outfit used was a tripod
