would have been destroyed. The work was mainly done by 

 women and boys, the stumps being stripped of bark to a 

 point well below the surface of the ground. The cost was 

 moderate, probably not exceeding 2s. 6d. or 3s. per acre. 

 The damage done by weevil during the succeeding summer 

 months was negligible, the pest being entirely under control. 



It is evident from this experiment that the removal of the 

 larvae from the stumps where an attack is expected can be 

 undertaken at moderate cost, and thus the delay of several 

 years in replanting is avoided, as well as the loss of rental 

 and the deterioration in the surface condition of the soil 

 which invariably follow where a cut-over area is left unstocked 

 for a period of years. J. H. Milne Home. 



The Uprooting of Trees. 

 ( With Diagram.) 



The attached rough sketch shows the method employed at 

 our Kirriemuir Company for removing the trees on the right-of- 

 way of the light railroad. 



The equipment consists of a 75-horse-power donkey engine, 

 an inch main line steel cable, and an inch haul-back cable. 

 The diagram gives a very fair idea of how the system works 

 out. In the first instance, the main strain is taken on what is 

 known as the lead tree, which is strengthened by being stayed 

 by a guy fastened to two trees close by. At the end of the 

 main cable there is a swivel, to which is attached a tag line. 

 The tree which is to be felled is snubbed about 7 feet from the 

 ground with a choker line, which in turn is hooked on to the tag 

 line. The swivel is important in order that no twist may be 

 possible on the main line. The haul-back line is fastened to the 

 main line cable on the swivel by means of scissor hooks. 



The felling commenced at the end nearest the engine. Each 

 tree as it was pulled down was limbed and cross cut, the main 

 cable being then pulled to the next tree by means of the haul- 

 back cable. No easing or cutting of the roots was found 

 necessary. 



I trust that the above information will be sufficient to give 

 an idea of the method. L. F. Strickford,
