 to which it is often exposed. What are known as two-year-old 

 seedlings and three-year-old transplants are the two grades 

 ordinarily employed in establishing commercial plantations. 

 The former has been grown for two years in a seedbed ; the latter 

 was transplanted after one or two years in a seedbed and has

grown one or two years since transplanting. Three-year-old 

 transplants cost approximately three times as much as two- 

 year-old seedlings and are much stronger plants. The present 

 tendency is to use seedlings only on the most favorable sites, and 

 this is the wiser course. 



The relative merits of pure and mixed forests have already 

 been discussed. It is safe to say that most of the planting in this 

 country will be pure, that is, that there will be little mixture of 

 species on the same area. This is because it is simpler and, on 

 the whole, a pure plantation of a tree well adapted to the soil is 

 more satisfactory than a mixture. It is well, however, for the
