3. Some Observations on Planting New Ground. 



By John Boyd.

 consider capable of growing timber and which would be more profit-

 Therefore it may not be out of place to make a few observations 

 on several phases of the subject that have appealed to the writer 

 during a few years' practical experience of the work, with the 

 hope that they may interest readers, and probably be of some
