x Introduction to Fifth Edition 



travelled over the greater part of the United Kingdom 

 and have examined much of the ground that could be set 

 aside for this purpose, including the peat bogs of Ireland ; 

 while at altitudes up to 1,100 ft. I have formed plantations 

 on the bare and wind-swept hillsides of Wales and Scotland, 

 which to-day are proving not only a boon to the farmers 

 in the way of the shelter they afford, but also a considerable 

 source of profit to the owners. 



The above investigations, combined with the examina- 

 tion of and reports on several of the largest woodland 

 properties in this country, made at the request of the 

 owners, have given me a wide insight into the forestry 

 problem generally, but particularly with reference to our 

 requirements in the near future, in view of the fact that 

 the United Kingdom is by far the largest timber importing 

 country in the world.
