vi PREFACE. 



Neither have I considered it necessary to alter 

 the figures in the calculations given as examples, 

 because there are no fixed figures which can be 

 accepted. Each example may be brought up to 

 date to meet increased wages, cost of seedling trees, 

 and other items. It should be borne in mind that, 

 though costs have increased, the value of timber has 

 increased in like proportion. 



Finally, I may express the hope that Forestry may 

 in the near future become a more practical and 

 necessary industry, on lines similar to those of 

 agriculture, and that landowners may recognise their 

 woodlands as one of their chief assets.
