F. sambucifolia —Blade Ash. 
F. viriclis —Green or Grey Ash. 
Ash.— Of this light colored tough wood we have in this 
market an abundant supply, including the four varieties of 
white, grey, black and bine. The white and grey is largely 
used for flooring and alternating with black walnut, or 
other dark wood, is much used for wainscoting and the 
inside finish of houses, in oil or varnish, without paint. 
The toughness, elasticity and straight grain of this timber 
make it superior to all other woods with the exception of 
hickory, in the manufacture of all classes of machinery 
which have to sustain sudden shocks—for which reason

black ash is largely used in making baskets, and all the 
ashes are superior street shade and ornamental trees. 
G1 editschia triacanthos —Three-thorned Acacia—Honey

A tall, but not large tree, with light foliage and large 
thorns, flattish at the base and tapering to a sharp point. 
The thorns are grouped in triangles one to three inches 
long. The tree is found generally on the rich soils. The 
bloom is quite fragrant. The acacia is much prized as 
an ornamental tree, and in the arts is approved as a mag¬ 
nificent finishing wood. Its thorns are used in the more 
primitive rural districts in place of buttons, and for fasten¬ 
ings for wool packages. 
Gymnocladus Canadensis —Kentucky Coffee tree—Nicker 
tree—Stump tree. 
Is a fine ornamental timber tree of good size. Height, 
forty to eighty feet. Blooms in the early summer. It 
ripens late in the fall a large indurated pod six to ten inches 
long and two wide, with seeds a half inch in diameter. It 
is a desirable street tree, but shoots from the root make it
