1 Tract stumped in the summer of 1913. 
The low cost of stumping was largely due to the sandy nature of the 
soil and the fact that the stumping crew was experienced. This work 
was done by the same contractor who stumped tracts Nos. 7 and 8. 
The stumps were piled and burned later in the year. 
TRACT NO. 10. 
Tract No. 10 contained 46 acres of nearly level silt-loam to clay- 
loam soil. In places the tract was very stony; round cobblestones 
predominated. The outfit used was a tripod stump puller. This 
tract had been logged 30 years before. The second growth and logs 
had been previously removed. 
The sizes of 114 white-pine stumps selected at random and meas- 
ured on this tract were as follows: 12-inch, 1; 18-inch, 2; 20-inch, 8; 
22-inch, 7; 24-inch, 22; 26-inch, 9; 28-inch, 10; 30-inch, 12; 32-inch, 17; 
34-inch, 9; 36-inch, 10; 38-inch, 1; 40-inch, 3; 42-inch, 1; 44-inch, 1; 
48-inch, 1. The average diameter was 28.6 inches and the average 
height 36 inches. The total number of stumps pulled was 1,812. 
The average number pulled per day was 48. The average number 
per acre was 39. This work was done under contract at 35 cents per 
stump for pulling and cleaning.’ The actual cost of pulling and clean- 
ing was 32 cents per stump, as shown in Table X.
