"<em>Genus</em> Saimiri. The animals of this genus are but about ten inches in length and are the most slender, graceful, and interesting of the whole monkey family. The large development of the brain is one of their most striking characteristics. The tail is slightly prehensile, yet used in climbing trees." &mdash;Goodrich, 1885

"Resemble the common squirrels, with a lateral membrane similar to that of the Pteromys. By means of this they make enormous leaps, sometimes nifty yards or more, from tree to tree, usually at first decending, and then rising and alighting in the manner of birds about to terminate their flight." &mdash; S.

In Illiois and canada it was given to a gray burrowing squirrel, in Wisconsin to a striped squirrel, and in Missouri to a burrowing pouched rat. All these are mammals; but in Georgia the term is applied to a snake, and in Florida to a turtle."&mdash;(Charles Leonard-Stuart, 1911)

"A bridge. As the rivers of Greece were small, and the use of the arch known to them only to a limited extent, it is probable that the Greek bridges were built entirely of wood, or, at best, were nothing more than a wooden platform supported upon stone piers at each extremity. Pliny mentions a bridge over the Acheron 1000 feet in length; and also says that the island Euboea was joined to Boeotia by a bridge; but it is probably that both these works were executed after the Roman conquest. The Romans were the first people who applied the arch to the construction of bridges, by which they were enabled to erect structures of great beauty and solidity, as well as utility. The width of the passage-way in a roman bridge was commonly narrow, as compared with modern structures of the same kind, and corresponded with the road leading to and from it. It was divided into three parts. the centre one, for horses and carriages, was denominated agger or iter; and the raised foot paths on each side decursoria, which were enclosed by parapet walls similar in use and appearance to the pluteus in the basilica." — Smith, 1873

"Dormoy's rabble differs from others of this class in being worked by rotation like a hair-brushing machine; the tool being made to revolve very rapidly (300 to 500 turns per minute for white iron and 800 to 1000 for grey pig) gives the metal such an impulse that it gyrates horizontally round the bed, continually renewing the surface in contact with the atmosphere; this is further aided, by making the end of the rabble to carry a disk, which is replaced by a short twisted point when the metal comes to nature." &mdash; The Encyclopedia Britannica, 1893

Leaves - compound (odd-feathered; leaflets, seven to nine); opposite; edge of leaflets slightly toothed or entire; entire at base. Outline - of leaflet, long oval or long egg-shape. Apex - taper-pointed. Base - somewhat pointed. Leaf/Stem - smooth. Leaflet/Stem - about one fourth of an inch long, or more; smooth. Leaf/Bud - rusty-colored and smooth. Leaflet - two to six inches long; pale beneath; downy when young, but becoming nearly smooth, except on the ribs. Bark - of the trunk, light gray. In very young trees it is nearly smooth, but it soon becomes deeply furrowed - the furrows crossing each other, and so breaking the bark into irregular, somewhat square or lozenge-shaped plates. Then in very old trees it becomes smooth again, from the scaling off of the plates. The branches are smooth and grayish-green. The young shoots have a polished, deep-green bark, marked with white lines or dots. Winged seeds - one and a half to two inches long, with the "wing" about one fourth of an inch wide, hanging in loose clusters from slender stems. The base of the seed it pointed and not winged. Found - in rich woods, from Southern Canada to Northern Florida and westward. It is most common in the Northern States. The finest specimens are seen in the bottom lands of the lower Ohio River basin. General Information - a tree forty to eighty feet high. Often the trunk rises forty feet without branching. Its tough and elastic timer is of very great value, being widely used in the manufacture of agricultural implements, for oars, and the shafts of carriages, and in cabinet-work. Fraxinus from a Greek word meaning "separation," because of the ease with which the wood of the Ash can be split. I find in the notes of an old copy of White's "Natural History of Selborne" this comment: "The Ash, I think, has been termed by Gilpin the Venus of British trees." Gerardes' "Herbal" comments: "The leaves of the Ash are of so great a vertue against serpents, as that the serpents dare not be so bolde as to touch the morning and evening shadowes of the tree, but shunneth them afarre off, as Pliny reporteth in his 16 book, 13 chap. He also affirmeth that the serpent being penned in with boughes laide rounde about, will sooner run into the fire, if any be there, than come neere to the boughes of the Ash." In Scandinavian mythology the great and sacred tree, Yggdrasil, the greatest and most sacred of all trees, which binds together heaven and earth and hell, is an Ash. Its roots spread over the whole earth. Its branches reach above the heavens. Underneath lies a serpent; above is an eagle; a squirrel runs up and down the trunk, trying to breed strife between them.

Leaves - compound (odd-feathered; leaflets, seven to nine); edge of leaflets nearly entire or slightly toothed. Outline - of leaflet, long oval or egg-shape. Apex - taper-pointed. Base - somewhat pointed. Leaf/Stem - velvety-downy. Leaflet/Stem - about one fourth of an inch long, or somewhat less, and velvety-downy. Leaf/Bud - rounded, nearly concealed by the leaf-stem, downy, and of a dark, rusty brown. Leaflet - two to six inches long, downy beneath, and pale, becoming reddish. Bark - of the trunk, dark ashy or granite-gray, or of a deep brown. It is slightly furrowed up and does, the furrows seldom joining or crossing. The branches are grayish. The young shoots are velvety, with a grayish or rusty down. Winged seeds - resembling those of the White Ash, but usually with the end of the wing more rounded. Found - along borders of streams and in low and swampy ground - New Brunswick to Minnesota, and southward to Northern Florida and Alabama; but rare west of the Alleghany Mountains. Its finest growth is in the Northern Atlantic States. General Information - A medium-sized tree, usually thirty to fifty feet high, of less value than the White Ash.

Leaves - compound (odd-feathered; leaflets, seven to eleven, usually nine); opposite; edge of leaflet toothed. Outline - of leaflet, narrow, long oval or long egg-shaped Apex - taper-pointed. Base - rounded. Leaf/Stem - lacking. Leaf/Bud - deep blue or blackish. Leaflet - three to five inches long, smooth and green on both sides, excepting where it is slightly hairy along the lower part of the middle rib. When crushed it has an Elder-like odor. Bark - of trunk, dark granite-gray, somewhat furrowed and broken up and down with roughness, which continue in the old tree. The young branches are smooth and grayish and marked with black and white dots and warts. Winged seeds - nearly one and one half inches long, with the wing three eighths of an inch wide and extending around the seed. Ripe in July. Found - along low river-banks and in swamps, which it sometimes fills; in Delaware, the mountains of Virginia, Northwestern Arkansas, through the Northern States to Canada. It is the most Northern of the American Ashes. General Information - Usually a small or medium-sized tree. The wood is largely used for barrel-hoops, baskets, in cabinet-work, and interior finish.
