FORESTRY 241 



following a few simple rules, any one who owns timber 

 land may harvest a crop of timber ju-t as regularly as 

 be harvests wheal ot torn. Let oa suppose the case of 

 a farmer who owns 800 acree of woodland and wishes 

 to derm an income from the sale of timber. Now, fan

 into sections of Bay ten acres each, and cut the 

 timber from one section each year; being careful to 

 protect the young timber from harm. By the time he 

 has cut over his 200 acres the young timber on the first 

 ten acres cut has had twenty years added to its growth, 

 and much of it will be ready for cutting. In this way 

 he derives a steady annual income from his timber.

 every two, three, or four years; say twenty acres every 

 other year, or twenty-five or thirty acres every three 

 years. By following some system such as this he can 

 derire a steady income from his timber land, and yet 

 hand it down to future generations uninjured.
