lower size than the White elm, attaining generally onlv 
40 or 50 feet. According to Michaux, it may be 
distinguished from the latter even in winter, by its buds, 
which are larger and rounder, and which are covered a 
fortnight before their development with a russet down 
The leaves are larger, rougher, and thicker than those 
of the White elm ; the seed-vessels larger, destitute of 
fringe ; the stamens short, and of a pale rose color. This 
tree bears a strong likeness to the Dutch elm, and the 
bark abounds in mucilage, whence the name of Slippery 
elm. The branches are less drooping than those of the 
White elm. 
The Wahoo elm (Z7. alata) is not found north of 
Virginia. It may at once be known in every stage of 
its growth by the fungous cork-like substance which 
lines the branches on both sides. It is a very singular 
and curious tree, of moderate stature, and grows rapidly 
and well when cultivated in the northern states. 
The common European elm. ( U ’. campestris.) This 
is the most commonly cultivated forest tree in Europe, 
next to the oak. It is a more upright growing tree than 
the White elm, though resembling it in the easy 
disposition and delicacy of its branches. The flowers, 
of a purple color, are produced in round bunches close 
to the stem. The leaves are rough, doubly serrated, 
and much more finely cut than those of our elms. It 
is a fine tree, 60 or 70 feet high, growing with rapidity, 
and is easily cultivated. The timber is more valuable 
than the American sort, though the tree is inferior to 
the White elm in beauty. There are some dozen or 
more fine varieties of this species cultivated in the 
English nurseries, among which the most remarkable are
