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 
ready 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 334 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 vears before, 7,000 white-pine 
stumps, averaging 22 inches in diameter, were pulled with a tiipod 
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. 
18, 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 tracts was about 300. The stumping and part of 
the piling was done from July 15 to October 1, 1912. The remainder 
of 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.
