16 - BULLETIN 91, U. S. DEPARTMENT OF AGRICULTURE. 
Because of the shallow rooting system and small size of the stumps, 
most of them could be pulled by a 2,800-pound team without the 
use of blocks and line. The stumps that could not be pulled by a 
team were split by a small charge of dynamite, and the remaining 
pieces were pulled out by a team. The second growth on this land 
consisted of poplar and bird cherry. Smalllogs were numerous. The 
various items entering into the cost of clearing were not kept sepa- 
rately. The superintendent said that they were approximately as 
follows:

TRACT NO. 7. 
Tract No. 7 contained 60 acres, principally of heavy clay soil, in 
a few places having sandy-loam soil with a heavy clay subsoil 6 inches 
below the surface. The land was nearly free from stones and was 
gently rolling. The outfit used was a tripod stump puller. This 
tract had been logged 20 years before. All the stumps were white 
pine. There was no undergrowth or logs. The tract had been pas- 
tured several years and at the time of stumping was covered with a 
fairly good clover sod. 
The sizes of 354 white-pine stumps selected at random and meas- 
ured on this tract were as follows: 12-inch, 2; 14-inch, 2; 16-inch, 11; 
18-inch, 28; 20-inch, 37; 22-inch, 35; 24-inch, 88; 26-inch, 65; 
28-inch, 42; 30-inch, 21;.32-inch, 13; 34-inch, 6; 36-inch, 4. The 
average diameter was 24.6 inches. The average height was 36 inches. 
The total number of stumps pulled was 2,464, the average per day 
being 54. Thé average number per acre was about 41. Details of the 
cost are given in Table VII. The stumps on this tract were piled 
in the fall of the year and will be permitted to dry out for about 
two years before any attempt will be made to burn them.
