rapidly. The locust grows somewhat faster than the mulberry, and 

 will form the upper story, while the latter will shade the ground and 

 assist in forcing the locust into a straight growth. The unequal spac- 

 ing will allow of long-continued cultivation in one direction, which is 

 very desirable in the semiarid regions. 



Plat 7 has been planted 4 feet by 8 feet with equal proportions of 

 white elm and black locust. This mixture is suited to the southern 

 half of the Middle West. The locust is the more rapid-growing 

 species, and will furnish posts and fuel at an early date, while the 

 elm will maintain conditions of shade and litter necessary for keeping 

 up the quality of the forest soil. The wide spacing in one direction 

 is to facilitate cultivation. 



Plat 8 has been planted 4 feet by 8 feet with an equal mixture of 

 black locust and Osage orange (bodark), and is suited to southern 

 Kansas, Oklahoma, and northern Texas. This mixture has the same 

 advantages as the plantation on plat 6. The Osage orange, however, 

 furnishes wood peculiarly well adapted for fence posts, for which in 

 the estimation of the farmers of the region it holds the first place. 

 The wide spacing in one direction will allow of cultivation, even after 

 the thorny Osage orange has grown to considerable size. 



Plat 9 is planted 4 feet by 8 feet with Osage orange (bodark) and 

 Russian mulberry in equal proportions. This mixture also is adapted 

 for the prairies of the southern half of the Middle Western States. 

 Wherever the black locust is infested with borers, the use of the mul- 

 berry and bodark for the production of fence posts may be the most 

 feasible solution of the difficulty. 



Plat 10 has been planted 4 feet apart with western yellow pine and 

 jack pine in equal proportions. This mixture of very hardy conifer- 

 ous species is adapted to sandy, poor soil in the prairies west of the 

 Mississippi and north of the fortieth parallel, where long-continued 

 cultivation is not practicable. The jack pine is the temporary species, 

 and should be cut out whenever it begins to interfere with the growth 

 of the yellow pine, which is designed to form the final stand. 



Plat 11 is planted 4 feet by 8 feet with black locust, Osage orange, 

 Russian mulberry, and hone} 7 locust in equal proportions. This mix- 

 ture is adapted to the semiarid prairies of the South Central States, 

 and is given chiefly for the purpose of illustrating a mixture of more 

 than two species. All these trees grow rapidly, endure great extremes 

 of drought, and furnish wood well adapted for fence posts. 



Plat 12 is planted 4 feet b} 7 6 feet with pure black locust. This 

 method of planting is suited to a large area of country south of the 

 fortieth parallel of latitude, wherever the black locust thrives. The 

 wide spacing in one direction is to facilitate cultivation. 



Plat 13 is planted 4 feet apart with boxelder and cottonwood in 

 equal proportions. This mixture is suited to the river bottoms of the
