Explosives. . 



There are many kinds of explosives on the market, most of which are 

 applicable to the varying work of land clearing. Gelignite, dynamite, rack-a- 

 rock, and black powder are the most generally known and distributed, and 

 are therefore comparatively easy to obtain; in normal times most of the 

 agents for explosives handle the above. They all have their advocates and 

 will all do good work ; but the conditions under which some will and some 

 will not, make it essential to explain in detail.
