FOREST RESOURCES 23 



Cottonwood. — Several species (Populus sp.) are found in 

 abundance and of large size in the bottoms of the lower Mis- 

 sissippi River. The greater part of the annual production comes 

 from the states of Arkansas, Louisiana and Mississippi. It is 

 in demand for boxes, wood pulp, lining for refrigerator cars, 

 excelsior, woodenware and cheap furniture. 



The cut in 1910 was 220,305,000 feet, which was the lowest 

 output in many years. 



The stumpage in Mississippi is valued at from $1.50 to $3 

 per thousand feet and in Indiana at from $6 to $10. 



Other Hardwoods. — There are many other hardwoods placed 

 on the market, among them tupelo or bay poplar {Nyssa aquat- 

 ica), which is manufactured into flooring, interior finish, plank- 

 ing, and box boards in Louisiana and other Southern States; 

 the cucumber tree {Magnolia acuminata) , sold largely as yellow 

 poplar; the buckeye {Mscidus glabra), manufactured into pulp, 

 interior finish and woodenware; sycamore {Platanus occiden- 

 talis), used for furniture and plug tobacco boxes; black walnut 

 {Juglans nigra); cherry (Prunus serotina); and other valuable 

 cabinet woods. These timbers with the exception of tupelo 

 are common to the South Central and Appalachian regions and 

 are associated with the other hardwoods.
