Cost of Subsoiling With Red Cross Dynamite 



The following table will give an approximate idea of the cost of 

 subsoiling, referring to the cost of materials only :

The labor cost will of course depend on the wages paid and the 

 ease or difficulty with which the holes are put down. Where very 

 tough hardpan is encountered the cost of putting down the holes may 

 amount to nearly the cost of the explosives and supplies. On the 

 other hand, where only a plow sole is encountered the holes can be 

 put down very rapidly and cheaply, and for that reason these tables 

 do not include labor cost. 



Where soil conditions are easy the holes can be put down at the 

 rate of about thirty per hour. Where soil conditions are difficult it may 

 take five minutes or more per hole. Priming the cartridges and tamp- 

 ing them in will take from two to three minutes per hole. In general, 

 subsoiling will seldom cost less than $10.00 an acre and will rarely 

 cost more than $25.00 an acre. 



Second Year Results Greater Than First 



ANDERSON, S. C, September 23, 1912. 



In reference to breaking land with dynamite for farming purposes will say 

 that the land so broken in the Spring of 1911 shows a greater improvement than 

 it did the first year. The upland corn was at least 40% better than the corn raised 

 on adjoining land that was not dynamited. I dynamited four acres this year and 

 I find a great difference in the corn compared with the adjoining land. The greatest 

 difference, as stated above, is the second year. I also broke some land for cotton 

 late in the spring this year and I am much pleased with the results, as the cotton 

 is still green and blooming and has stood the dry weather better than the other 

 land. 



Yours very truly,
