A fine stand of second-growth oak. This woodlot will at some future time 

 cut a lot of good logs, poles, posts and fuel wood. 



Yield. The cottonwood will probably return the greatest 

 financial yield per acre per year of any tree that is suitable for 

 woodlot planting. As shown in the accompanying table, a 

 normal yield at forty years of age is thirty thousand board 

 feet per acre, which at $12 per thousand is $360 per acre, 

 equivalent to a rental value of $9 per acre per year. There is 

 no other species that can be planted in this state that will 

 yield more than half this amount of lumber in the same length 

 of time. Because of its rapid rate of growth it requires less
