or $22.50 per acre. The contractor still considers $30 a fair price, but 

 owing to circumstances and bad weather wages were not made upon 

 this work. 



In another case in this neighborhood the owner of 640 acres of land 

 gave all the Norway-pine stumps on it for the clearing of 15 acres 

 readv for the plow. 



TRACT NO. 16. 



On a tract of 35 acres of nearly level land, having a sandy-loam 

 surface soil and a clay subsoil, which had been logged 30 years before, 

 1 ,050 white-pine stumps, averaging 26 inches in diameter, were pulled 

 with a tripod machine at a contract price of 33$ cents per stump for 

 pulling, cleaning, and tipping. 



TRACT NO. 17. 



On another tract of 105 acres of nearly level land, having a sandy- 

 loam surface soil and a clay subsoil averaging 18 inches below the 

 surface, which had been logged 25 to 40 years before, 7,000 white-pine 

 stumps, averaging 22 inches in diameter, were pulled with a tripod 

 machine at a contract price of 25 cents per stump for pulling, cleaning, 

 and tipping. These stumps were hauled into fence rows for 18 cents 

 per stump, contract price. 



TRACT NO. 18. 



On a tract of 10 acres of gently rolling land having a sandy and 

 gravelly loam surface soil and in places a clay subsoil, which had been 

 logged 25 years before, 600 white-pine stumps, averaging 18 inches in 

 diameter, were pulled with a tripod machine at a contract price of 30 

 cents each for pulling, cleaning, and tipping. 



TRACT NO. 19. 



On an adjoining tract of 16 acres, with soil the same as in tract No. 

 is. and using the same outfit, 330 stumps were pulled, cleaned, and 

 tipped for 30 cents each. The contractor took both jobs at a flat rate 

 of 30 cents per stump. 



TRACT NO. 20. 



Tract No. 20 contained 18 acres of cedar-swamp land that had 

 been very severely burned in 1908 and 1911. The soil varied from 

 a clay loam to a heavy clay. Practically all the roots had been 

 burned off. The stumps rested on top of the ground. One horse 

 could easily pull nearly every stump on this tract. The few stumps 

 that were too firmly rooted to be pulled by a horse were loosened 

 by the use of dynamite. The number of trees and stumps per acre 

 on adjoining similar tract- was about 300. The stumping and part of 

 the piling was done from July 15 to October 1, 1912. The remainder 

 <>f the piling and all of the burning was done after April 12, 1913. 

 The work of clearing was thorough. The details of cost are shown 

 in Table XIV.
