rapidity of growth and early maturity, while the walnut, developing 

 into large proportions, will form a permanent forest on the planting 

 site long after the disappearance of the catalpa. 



Plat 20 has been planted 4 feet by 8 feet with black walnut. This 

 species is adapted to planting on fertile soils from southern Minnesota 

 to Texas, and from West Virginia to Kansas. It produces very valu- 

 able cabinet wood. The heartwood of the walnut is very durable in 

 contact with the soil, forming one of the best fence-post timbers we 

 have. Wide spacing between the rows allows of long continued culti- 

 vation, while at the same time the close spacing in the rows secures a 

 sufficient density for the production of well-shaped trees. 



Plat 21 has been planted 6 feet by 6 feet with pecan and black 

 walnut in equal proportions. This mixture is adapted to the river 

 bottoms of southern Kansas, Indian Territory, Oklahoma, and Texas. 

 The wood of the pecan possesses many of the valuable qualities of our 

 hickories, while the species grows fairly rapidly. Its association with 

 the walnut will make an excellent long-lived plantation where early 

 maturity of the product is not absolutely essential. 



Plat 22 has been planted 6 feet by 6 feet with pecan. This species 

 is adapted to the rich river bottoms in the southern half of our coun- 

 try east of the Rocky Mountains, and may often be profitably planted 

 for both timber and nuts. 



Plat 23 has been planted 4 feet by 8 feet with hardy catalpa and 

 Russian mulberry. This mixture is suited to the river valleys south 

 of the forty-first parallel and east of the ninety-eighth meridian. The 

 Russian mulberry is introduced into the plantation in order that it 

 may assist in pruning the catalpa, thereby compelling that tree to grow 

 clean and straight. 



Plat 24 is planted 6 feet by 8 feet with sycamore and Carolina pop- 

 lar in equal proportions. These species are very hardy, rapid-growing 

 trees, adapted to the river bottoms of the Middle West south of the 

 forty-fifth parallel of latitude and east of the Rocky Mountains. 



Plat 25 is planted 4 feet by 4 feet with slippery elm and black cherry 

 in equal proportions. These trees are adapted to the region north of 

 the thirty-eighth parallel and south of the Great Lakes and Minnesota 

 and east of the Missouri River. The mixture should be limited to 

 moist, well-drained soils. 



Plat 26 is planted 4 feet by 4 feet with arborvitse and white spruce 

 in equal proportions. This mixture is suited to swampy or moist, 

 untillable land in the Northern States east of the Mississippi. The 

 arborvitae produces an excellent fence post or telegraph pole, and when 

 ripe for these uses may be cut out, leaving the spruce as the perma- 

 nent stand. 



Plat 27 has been planted 4 feet by 8 feet with tamarack and balsam 

 fir in equal proportions. This mixture is suited to moist land in the 

 New England and Lake States. The tamarack produces an excellent
