and suppled by pounding, it is used in the Northern States for 

 the bottoms of common chairs. The wood makes good fuel, 

 and produces ashes strongly impregnated with the alkaline 

 principle. 



Red or Slippery Elm. Ulmus rubra. 



Except the maritime dis- 

 tricts of the Carolinas and 

 Georgia, this species of elm 

 is found in all parts of the 

 United States and of Canada. 

 It bears the names of Red 

 Elm, Slippery Elm and 

 Moose Elm, of which the 

 two first are the most com- 

 mon. The French of Can- 

 ada and "Upper Louisiana 

 call it Orme gras. This 

 tree is less multiplied than 

 the white elm, and the two 

 species are rarely found 

 together, as the red elm 

 requires a substantial soil 

 free from moisture, and even delights in elevated and open 

 situations, such as the steep banks of the Hudson and the 

 Susquehannah. In Ohio, Kentucky and Tennessee it is more 

 multiplied than east of the mountains, and grows on the richest 

 lands of an uneaven surface. 



This tree is 50 or 60 feet high and one or two feet in diameter. 

 In the winter it is distinguished from the white elm by its buds, 

 which are larger and rounder, and which a fortnight before their 

 developement, are. covered with a russet down. The leaves are 

 oval-acuminate, doubly denticulated and larger, thicker and 

 rougher than those of the white elm, and emit an agreeable odor. 

 It blooms in the month of April. The flowers are aggregated at
