 per acre; and after that, a triennial profit of about 12/. per acre, 

 until the oak left standing may be supposed to be fit for the naval

The following estimate of the expense of purchasing, planting, 

 fencing, and subsequent management of an acre of poor moun- 

 tainous land with larch, and also of the returns during a period of 

 sixty years, was drawn up with a view to promote the formation of 

 a society for the provident investment of money : —
