ELMS 



Four elms are found in Ohio, the white or American elm {Ulmus 

 americana), the red or slippery elm ( Ulmus pubescens), the rock or 

 cork elm ( Ulmus racemosa) and the winged elm ( Ulmus alata). The 

 white elm and the slippery elm are more frequent and more widely 

 distributed, the former being- the most important commercially but 

 on the market rarely any distinction is made. The trees are usually 

 distinguished by the bark and the leaf; the inner bark of the slippery 

 elm being* mucilaginous and nutritious and has a leaf with a very 

 rough upper surface, whereas the white elm leaf has a smooth sur" 

 face and the outer bark, like all of the other elms, is deeply furrowed. 

 Elm wood has properties which fit it for a number of special uses. 

 In some respects it is one of the best American woods, its elasticity, 

 for instance, is exceeded only by hickory. Bicycle rims have been, 

 largely made of it on account of its resiliency and tensile strength, 

 the same qualities that have made it preeminently the best wood for 

 patent barrel hoops. Its scarcity prevents its use for many articles 

 where it would be of exceptional value. Generally a large 'supply of 

 elm goes into the manufacture of farm implements, slack barrel 

 staves for flour barrels, bent parts of chairs and vehicle bodies, 

 banjo rims, piano case parts, etc. The principal uses in Ohio are 

 indicated by the industries calling for it, which are:
