The average height of the pine stumps was 33 inches. The average 
number pulled each day was 48. The cost of pulling, cleaning, and 
tipping was 25.9 cents 
per stump. Dynamite 
had been used in stump- 
ing this land, but be- 
cause of the loose nature 
of the soil it had proved 
too expensive. 
TRACT NO. 5 
Tract No. 5 contained 
50 acres of very gently 
rolling pasture land 
with sandy-loam soil 
and clay subsoil. The 
outfit consisted of a 
capstan stump puller, 
shovels, axes, and bars. 
The stumps were piled 
by the device shown 
in figure 9. Details of 
the cost of removing 
1,018 stumps from this field are given in Table V.
