YIELD AND FINANCIAL RESULTS. 47 



It will be observed, that it pays to grow on such land larch, 

 ash (if the soil is otherwise suitable), Scotch pine and even 

 spruce. As regards beech and oak the margin is small ; hence 

 I shall give some further information regarding oak. Sup- 

 posing we grow oak on land of the first yield capacity : in 

 that case the following returns may be expected :

Final yield = 130 -- 6,400 Is. Gd. = 9,600 



If we make the calculations as before we obtain the following 

 results :

This shows that it pays to grow oak on really good land 

 valued up to 30 an acre (on average land up to '12). 

 In other words, land of good quality which lets for more than 

 15s. net an acre if used for agriculture, will lead to loss if 

 put under oak. 



Before I leave this subject, it will be as w r ell if I show the 

 financial results in case not large timber but only poles are
