Cost With Mechanical Puller 



Puller and two yoke of oxen, per day $5.00 



Three men at $1.50 per day 4.50 



Total $9.50 



Number of stumps averaged, per day 40 



Cost per stump 1-40 of $9.50= $ .24 



Cost By Blasting 



(Labor figured at $1.50 per day) 



Cost of boring stump $ .025 



Cost of charge of dynamite (average) 07 



Cost of detonator 01 



Cost of fuse 01 



$ .115 or lie. 



This indicates a saving of at least 12c. per stump by the use of 

 dynamite. Figuring 100 stumps to the acre, which is certainly not 

 excessive, the saving will be $12.00 per acre. 



The extremely low cost of blasting a stump is further illustrated 

 by these figures which we quote from the Engineering Contracting 

 Magazine of May 13, 1908. They refer to the blasting of 3,500 stumps 

 18 inches to 7 l /2 feet in diameter, averages, of course, being given. 

 This work was done on Long Island. 



Cost per Stump 



Labor (at $2.00 per day) $ .059 



Dynamite 086 



Caps 008 



Fuse . .009 



Total cost per stump $ .162 



By preparing the charges the evening before, one man blasted 

 100 stumps in one day, thus reducing the labor item to a little over 

 2c. per stump. It will be observed that these were very large stumps. 

 Of course, the skill of the blaster counts for much. The more care 

 and judgment is used, the more economical the blasting. 



Dynamite Cheaper Than Stump Puller 



I blasted from my property 1,000 white pine stumps averaging about two 

 and a half feet, all of which were removed very successfully with Red Cross 

 Dynamite. 



This land was always unproductive prior to 1910 when I started to farm, 

 but by removing these stumps I have reclaimed about eight acres, which were 

 planted to corn and potatoes in 1910 and 1911. 



I have approximately 7,000 more stumps on this property, all of which will 

 be removed as quickly as possible, and it will be dynamite for me all the time, 

 as I find its use easily one-half cheaper than it was possible to do this work with 

 a team and stump puller. 



We had a stump puller but sold it as we found that dynamite did the 

 work easier, cheaper, and quicker and the results were better.
