Clearing Costs Reduced 



The recent land clearing tests conducted by the University of 

 Wisconsin have revolutionized methods and established conclu- 

 sively much lower clearing costs per acre 



The leading kinds of stump pullers — hand and power — were 

 represented. The dynami'e used was 



R.CD CROSS FARM POIVDER 



These tests proved the following important facts: 

 1st — The cheaper Red Cross Farm Powders will in most soils blast 

 out stumps as well as the most expensive 30% and 40% grades. 





2nd — The combined use of Red Cross Farm Powder and a slump 

 puller is often the cheapest and best way to clear land. 



3rd— Properly placed charges fired with a blasting machine greatly 

 reduce the amount, strength and cost of the dynamite required. 



As a result the average stump covered land can now be cleared at 

 less cost per acre than before the war
