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.
