IS ADVICE FOE FOREST PLAXTEES IN OKLAHOMA. 



usually have more sapwood than those of the same kind that grow 

 slowly, and hence have wood that is less durable and sometimes less 

 valuable in other ways than old tree-. Young black walnut in par- 

 ticular generally has a large portion of light-colored sapwood that is 

 relatively of little value. Catalpa, however, produces little sapwood 

 under any circumstances, and the rapidly grown wood is more val- 

 uable than that grown -lowly, because straighter. The sapwood of 

 hickory is tougher and better than the heart. 



The catalpa trees arc to be set 3 feet apart in rows 8 feet apart, 

 the walnut and red oak approximately 4 feet by s feet, and the 

 mixtures of hickory and collective the same. The walnut and pecan 

 are to he set 6 feet by s feet, iu order that they may produce nut- as 

 well a- timber. No attempt was made' to set the tree- in check rows 

 on any of these plantation-. The wide spacing in one direction will 

 permit long-continued tillage, which is. very desirable, particularly 

 with the nut t rees. 



It' the plantation- made under this planting plan are carefully 

 attended to. the growth of the tree-, particularly of the catalpa. will 

 he -o rapid that some returns may he expected within ten years. At 

 that age about half the catalpa tree- in the pure plantation should be 

 cut out for fence posts. After about fifteen years more the remainder 

 should be suitable d>v telegraph pole-. If the latter are desired, the 

 side branches should be pruned from the tree- as soon as they die.

 the various species proposed for this plan :
