276 Practical Forestry 



showed that both sound and unsound stumps could be suc- 

 cessfully blasted, and whole trees an Apple and an Oak 

 were also uprooted by the same method with equal success, 

 using only one bore-hole and about the same charge of 

 explosive. The timber of the trees so treated, however, 

 is very much split, so that blasting is only advisable when 

 the timber is considered of little value. 



The particular explosives used are unaffected by damp, 

 and, in consequence, the method is applicable in both wet 

 and dry situations. Firing the charges was done at the 

 demonstrations mostly by ladies, and a photographer was 

 able to get sufficiently near to obtain photographs of the 

 effect of the explosion without danger. The principal recom- 

 mendations of this method, therefore, are cheapness, effective- 

 ness and safety.
