54 OHIO EXPERIMENT STATION: MONTHLY BULLETIN 



that does not warp, shrink, twist or splinter, which is light. yet 

 strong and capable of withstanding shock. It grows in all parts 

 of Ohio but requires a fairly deep, fertile soil, moist but not wet. 

 It should not be planted on abandoned fields nor on dry exposures 

 in southeastern Ohio. The growth of the walnut is moderately 

 rapid. 



Sugar maple, Acer saccharum. Sugar maple is a native 

 species of good timber value, and prized by many on account of its 

 sugar product. It was distributed quite generally over the State 

 in the native forest. The species is a moderate grower, of good 

 form, requiring soils of moderate fertility. It may be planted in 

 groves and on account of its tolerance can be used to fill gaps in 

 woodlands. The original beech-maple groves are a good criterion 

 of its natural range. Avoid its use in dry sterile soils. 



Cottonwood, Populus deltoides. Cottonwood is a native of 

 species of extremely rapid growth and good form. It requires 

 deep, moist soils, and is especially adapted for planting overflow 

 lands along streams. Its wood is used in the manufacture of 

 paper pulp, and its timber is tough and strong and is useful for 

 many purposes. It should not be planted on dry soils. It will 

 yield approximately 20,000 board feet of lumber per acre in 30 

 years, or 50 cords of pulp wood per acre in 20 years. 



Basswood, Tilia Americana. This is a native species the wood 

 of which is similar to the tulip poplar. It is especially valuable 

 for special uses in making beehive squares, fruit baskets and 

 wooden ware. It requires soils of moderate strength but will not 

 thrive on wet clays. Its growth is moderately rapid. 



POST TIMBERS 



A number of species may be planted for fence post timbers. 

 A considerable number of kinds of wood are used for this purpose. 

 The following species are recommended because more is known of 

 their habits of growth and the durability of their wood. 



Osage orange, Toxylon pomiferum. A native of the Red 

 River district and restricted in its natural range. Planted in 

 various parts of the United States in the 'seventies for hedge pur- 

 poses, it has proved unpopular for this use. Its wood is probably 

 the most durable that can be grown in the United States. It is 

 far ahead of any native timber in this respect. The tree does not 

 attain a large size and is of rather poor form. Its growth is 

 moderate but the stems can be used for posts in small sizes, owing 

 to its extreme durability. It does best in soils of moderate fer- 

 tility^ will not tolerate wet places and is somewhat inclined to
