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.

The pulling was done in 45 days, an average of 23 per day. The 

 average number of stumps per acre was about 20. This tract was 

 logged 30 years ago. Fires had kept down all underbrush. All logs

 set on fire at night, and usually the following morning the unburned 

 stumps were repiled. The sizes of 87 white-pine stumps measured
