has been got rid of. It also necessitates the work of two men ; at least, two men 

 can do it to very much better advantage than one. Although less costly as regards 

 actual outlay of money, on account of the very much smaller amount of powder used, 

 it is rather slower. The system is as follows: 



Instead of using a big charge of powder often as much as a whole box (50 Ib.) 

 as is necessary under the system described above, a very much smaller charge is 

 used, approximately about a fifth to a seventh of 50 Ib. It is impossible to lay down 



any fixed figures for this ; experience 

 alone can determine. A deep hole is 

 put underneath the stump as deep 

 as it can be got in the same way 

 as that previously described. After 

 the shot has gone off none of the 

 stump is blown out, tout all of it is 

 lifted perhaps 6 to 12 inches and the 

 ground slightly heaved. The top of 

 the stump will have been split into 

 four or more portions and will lean 

 outwards, making open forks of the

upper part of the stump (see Fig. 



10), and the dirt will have been 

 blown clear from the centre. Into the forks of the stump are piled up all the 

 logs and loose roots and rubbish -within easy reach so as to make a big fire. 

 Do not be afraid to make a big one. While this is burning the various roots 

 leading from the stump are traced down, and at about two-thirds of the length 

 (anything from 10 to 20 feet from the stump, depending upon its size) the root 

 is uncovered and is chopped through. This procedure is followed with all the 

 roots which can be got at. By the time this is done the heart of the stump will 

 have burned itself out. A long pry or pole, as big as two men can handle, is then 

 procured. This is inserted underneath the chopped-off root and the end where it 

 was chopped pried up so that the split portions of the stump, separated by the 



blast, are forced back together again. This will result in the ends of the roots 

 being left sticking up in the air (see Fig. 11). The bringing together of the tops of 

 the stump will usually cause the fire to start up again. More logs and roots are piled 

 on and by the time this second fire goes down it will be found that practically all 

 the roots which were pried up are loose and can be rolled into the fire. This leaves 

 the toes of the various roots which were chopped off to be dug out by hand, but this
