ces, forms a tree of the second or
third order, with a handsome outline,
and picturesque appearance.
In its
natural habitat, it seldom exceeds the
height of twenty feet, although in a
state of cultivation, it often attains
more than double that elevation.

Varieties. In the Acer campestre, we recognize six forms or varieties, which may be described as follows:

1. A. c. HEBECARPUM, Loudon. Downy-fruited Field Maple. This variety is the form usually regarded by British authors as the type of this species, and is characterized as rather a small tree, with spreading branches; the bark corky, and full of fissures; that of the branches smooth. The leaves about one and a half inches broad, downy while young, as are their footstalks, obtusely fivelobed, irregularly notched, and sometimes quite entire. The flowers grow in clusters, which terminate the young shoots; they are hairy, erect, short, somewhat corymbose, and of a green colour. The anthers are hairy between the lobes. The capsules downy, spreading horizontally, with smooth, oblong, reddish wings.

2. A. c. FOLIIS VARIEGATIS, Loudon. Variegated-leaved Field Maple. This variety is considered as the handsomest of all the variegated-leaved Maples.

The leaves are blotched and striped with white, or whitish-yellow, and preserve their vegetation with a healthy appearance.

3. A. c. COLLINUM, Loudon. Hill-inhabiting Field Maple. This variety is a native of France. The fruit is smooth; the lobes of the leaves obtuse, and the flowers small.

4. A. c. AUSTRIACUM, Loudon. Austrian Field Maple. This variety, as its name imports, is a native of Austria; also of Podolia, and Tauria. It is larger in all its parts than the Acer campestre hebecarpum, and is of much freer growth. The trunk rises erect and straight, and sends out its branches regularly on every side, so as to form a cone, almost like a fir-tree. The lobes of the leaves are somewhat acuminated, and the fruit is smooth.

5. A. c. LEVIGATUM, Loudon. Smooth-leaved Field Maple.

6. A. c. NANUM, Loudon. Dwarf Field Maple.

Geography and History. The Acer campestre is found throughout the middle states of Europe, and in the north of Asia. According to Pallas, it abounds in New Russia, and about Caucasus. It is common in hedges and thickets in the middle counties and south of England; but in the northern counties, and in Scotland, it is rare. It is not indigenous to Ireland, and perhaps not to Scotland.

The largest tree of this species in Britain, and possibly on the globe, is at Blairlogie, in Stirlingshire, which, in 1835, was three hundred and two years old, fifty-five feet high, with a trunk four feet in diameter, and an ambitus or spread of branches of forty-five feet. Another tree at Braystock, in Essex, had arrived at the height of fifty feet in eighty years.

In France, in the botanic garden at Toulon, there is a tree of this species, which attained the height of forty-five feet at forty-eight years after planting. In Saxony, at Wörlitz, there is an Acer campestre, which attained the height of forty feet, in sixty-five years after planting.

This species was introduced into the United States in 1822, by the late Mr. Prince, of Flushing, New York, and may be found in the American nurseries and collections.

Soil, Situation, &c. A dry soil suits the Acer campestre best, and an open situation; but, to attain a timber-like size, it requires a deep, free soil, and a situation sheltered by other trees. In nurseries, plants of this species are raised from seeds, most of which often remain eighteen months in the ground before they come up, though a few vegetate the first spring. The varieties are propagated by layers.

Insects, &c. There are but a few insects or their larvæ which appear to feed upon the leaves of this species, with the exception of a small, dark-green aphis; and the tree is not much liable to accidents and diseases. Loudon observes that the misletoe is sometimes found growing upon it.

Properties and Uses. The wood of the Acer campestre, when allowed to become a tree, and of a proper age, is very compact, possesses a fine grain, sometimes beautifully veined, and is susceptible of a high polish. When dry, it weighs fifty-two pounds to a cubic foot. It makes excellent fuel, and produces charcoal of the best quality, which is sometimes employed in the manufacture of gunpowder. It was celebrated among the ancient Romans for tables; and Pliny, who has treated at length upon the brusca and mollusca, the names under which the knobs and excrescences of this tree were known, informs us that cabinetwork of the most costly description was fabricated from them. In France, and other European countries, it is still extensively used by turners, carvers, and cabinet-makers, and the wood of the roots, which is often knotted and curiously marbled, is wrought into snuff-boxes, pipes, and various other articles of fancy.

The British poets generally place a maple dish in every hermitage they speak of. Wordsworth, in his "Ecclesiastical Sketches," says:

Methinks that to some vacant hermitage

My feet would rather turn,-to some dry nook
Scooped out of living rock, and near a brook
Hurled down a mountain-cave, from stage to stage,
Yet tempering, for my sight, its bustling rage
In the soft haven of a translucent pool;
Thence creeping under forest arches cool,
Fit haunt of shapes whose glorious equipage
Would elevate my dreams. A beechen bowl,
A maple dish, my furniture should be;
Crisp, yellow leaves my bed; the hooting owl
My night-watch; nor should e'er the crested fowl
From thorp or vil his matins sound for me,
Tired of the world and all its industry.

Wilson and Cowper both furnish the hermit's cell with the article so requisite for such a habitation:

The young shoots of this tree, being tough and flexible, are employed by coachmen, in some parts of France, instead of whips. In that country it is also much used for forming hedges, and for filling up gaps in old fences. It is advantageously employed in topiary works, and in geometrical gardens, being found to bear the shears better than most other trees. The leaves and young shoots are gathered green, and dried, for winter provender for cattle. The sap yields more sugar, in proportion to the quantity taken, than that of the sycamore.

HIS genus was constituted by Moench from the Acer negundo of Linnæus, and comprises three species, one native of CochinChina, one of California, and the other of Canada and the United States. The Dobinea vulgaris, a hardy shrub, native of Nepal, with elliptical, oblong, acutely-serrated leaves, belongs to the same natural family. No other genus, has hitherto been discovered, or recorded as belonging to the order Aceracæ, either of a hardy or tender

nature.

Derivations. The meaning of the word Negundo, is unknown. It is supposed by some to have originated among the French of Illinois, and had some connection with the tremulous and playful motions of the long pinnated leaves of this tree. The Illinois name, Erable à giguières, signifies, literally, romping or frisky maple. The specific name, aceroides, is derived from the Latin, acer, a maple, and the Greek, eidos, resemblance, and was originally applied by Moench, from the analogy this spe cies bears to the maples. The specific name, fraxinifolium, is derived from the Latin, frazinus, the ash, and folium, a leaf. Engravings.

Description.

HE Negundo fraxinifolium, in favourable situations, attains a height of forty or fifty feet, with a diameter of fifteen to twenty inches. The bark of the trunk is brown, the inner portion of which has a disagreeable odour; and that of the young branches is of a smooth, rush-like appearance, interrupted only by a few buds, and is of a beautiful pea-green, like the shoots of the Jasminum officinale, but on a larger scale. The trunk ramifies at a small distance above the ground, and forms a loose, and wide-spreading head. The leaves are opposite, and from six to fifteen inches long, according to the vigour of the tree, and the moisture of the soil in which it grows. Each leaf is composed of two pair of leaflets, with an odd one. The leaflets are petiolate, oval-acuminate, and sharply

toothed. Towards autumn, the common petiole becomes of a deep red. The flowers are produced profusely, in April or May, and appear with the leaves. They occur in slender pendulous racemes, are small, and of a green colour, which renders them difficult to be seen, unless they be closely watched in the flowering season. The racemes of fruit, that succeed the flowers, increase gradually to the length of six or seven inches, and as the season advances, they appear conspicuous among the foliage.

Variety. According to Loudon, there is a variety of this species growing in the arboretum of the London Horticultural Society, called Negundo f. crispum,
