found in cold, shaded exposures, along the whole range, to their termination in Georgia. In many of the forests of Maine and New Hampshire, this species constitutes a great part of the undergrowth, seldom exceeding ten feet in height but where it is not shaded by other trees, it attains a height of twenty feet and upwards.

This tree was introduced into England in about 1760, and was cultivated, not far from that time, by Miller. It was probably soon after introduced on the continent, where it is still growing in many of the gardens.

The largest tree of this species in Europe, and probably on the globe, is at Schönbrunn, in Germany. In 1835 it was between thirty and forty feet high, with a trunk eighteen inches in diameter.

The largest specimen in England, in 1835, mentioned by Loudon, was at White Knight's, near Reading. At twenty-five years after planting, it was twenty-one feet high. Another tree is noticed by him at Oriel Temple, in Ireland, which, at thirty-five years planted, was twenty-seven feet high.

Properties, Uses, fc. The wood of the Acer striatum is white, and finegrained and is sometimes used by cabinet-makers as a substitute for holly, or other woods, for forming the lines with which they inlay mahogany. According to Michaux, in Nova Scotia cattle are fed with the leaves of this tree, both in the green and dried state; and in spring, when the buds begin to swell, horses and cattle are turned into the woods to browse on the young shoots, which they devour with avidity. The same thing is practised, at present, in regions where this tree abounds, both in Canada, and in the United States.

From the great beauty of the bark and foliage of this tree, it deserves a place in every collection. It is propagated by seeds, or by grafting on the Acer pseudoplatanus.

NO HE Large-leaved Ma

ple is one of the most
graceful of trees in the

country it inhabits, varying from forty to ninety feet in height, and from two to five feet or more in diameter. The trunk is covered with a rough, brown bark, and the branches are wide and spreading. The leaves vary much in size, and also in the manner in which they are lobed. Some are cut nearly to the base, so as almost to merit the appellation of palmate, while others are not more deeply cut than those of the Acer platanoides. The largestsized leaves are nearly a foot broad. The flowers are of a greenish-yellow, and very fragrant, appearing in April and May. The fruit is hispid, with elongated, slightly diverging, glabrous wings.

Geography and History. The Acer macrophyllum is a native of the northwest coast of North America. It is found exclusively in woody, mountainous regions along the sea-coast, between forty and fifty degrees of latitude, and on the great rapids of the river Columbia.

" This noble tree," observes Dr. Hooker, "was unquestionably discovered by Mr. Menzies, the first naturalist who visited the coast where it grows." Mr. David Douglass, who subsequently found it, prophetically adds, "It will, at some future time, constitute one of our most ornamental forest trees in England.” It was introduced into Britain in 1812, where, however, it had not flowered in 1835. The largest specimen of this tree is in the garden of the London Horticultural Society, where it attained a height of twenty-five feet in twenty-three years.

Properties and Uses. The wood of the Acer macrophyllum is whitish, beau- . tifully veined, and resembles the curled maple. It is said to exhibit a grain scarcely inferior in beauty to the finest satin-wood. Hence, from its great size, it cannot fail to be admirably adapted for cabinet-making, as well as for numerous other purposes. The tree contains, perhaps, as much sap as any of its congeners, except the Acer saccharinum; but it is not used by the natives for making sugar.

This magnificent species cannot be too warmly recommended to the attention of amateurs and planters, as it is perfectly hardy and well suited for general cultivation, both in Europe and in America. It is propagated by layers in the nurseries of Messrs. Loddiges, where the annual shoots often acquire a length of six to ten feet.

CHE Acer platanoides

is a handsome tree, of
the first rank. Its

general appearance, at a distance, is like the Acer pseudo-platanus, but on a nearer approach, the leaves are found of a smoother and finer texture. The trunk is somewhat shorter than that of the sycamore, and the tree seldom exceeds sixty or seventy feet in height. The roots extend considerably, both laterally and downwards. The bark is green on the young shoots, but it afterwards becomes of a reddish-brown, dotted with white spots; that of the trunk is brown, and somewhat cracked. The buds are large and red in autumn, becoming of a still darker hue in the course of the winter; those on the points of the shoots are always the largest. The leaves are thin, green on both sides, and shining. In an early or half-expanded state, they are of a delicate yellowish-green, and in autumn, before they fall, become of a clear red, or of a rich, warm yellow. They fall, in England, about the end of October. When the petiole is broken, an acrid, milky sap issues from it, which coagulates on being exposed to the air. The leaves are about five inches long, and nearly of the same width. The petioles are longer than the leaves. The flowers appear just before the leaves, near the end of April, and form a short raceme, somewhat corymbose. They are yellowish-green, sweetscented, and eagerly sought after by bees, to which they afford an early, and at the same time, a valuable pasture. The fruit or keys have their wings yellow. They ripen in England in September and October, and generally prove abortive until the tree arrives at an age of nearly forty years.

Varieties. At least four varieties of the Norway maple are known, and may be distinguished as follows:

1. A. P. LOBELII, Loudon. Lobel's Platanus-like Maple. The leaves of this variety are very slightly heart-shaped, irregularly toothed, five-lobed, with the lobes more or less abruptly pointed. The bark of the young wood is striped, somewhat in the manner of that of the Acer striatum; by which circumstance the plant, in the young state, may readily be known. It is a large tree, native of the kingdom of Naples, and found on mountains.

2. A. P. PUBESCENS, Loudon. Downy-leaved Platanus-like Maple. This variety may be distinguished by the pubescence of the leaves on their under sides.

3. A. P. ALBO VARIEGATUM, Loudon. Silvery Variegated-leaved Platanus-like Maple. This variety has been represented as having its foliage beautifully and handsomely marked; but it is thought to be inferior in beauty to the variegated sycamore.

4. A. P. LACINIATUM, De Candolle. Cut-leaved Platanus-like Maple. This is a very distinct variety, with the leaves deeply and variously cut. There is a sub-variety of this race, sometimes called by nurserymen, the eagle's claw, or hawk's-foot maple.

Geography and History. The Acer platanoides is a native of Europe, from the west coast of Norway to Switzerland, and from France to the eastern boundary of European Russia. Pallas says that it does not occur beyond the Ural Mountains, or in Siberia, but that it is common through all the woods of Russia. In the north, it forms a stunted bush, but in the Ukraine it is a lofty tree.

This species is recorded as having been first cultivated in Britain in the Edinburgh botanic garden, by Mr. James Southerland. It is also stated by the late Dr. Walker, of Edinburgh, that it was first introduced at Mount Stewart in 1738. Since that time it has very generally been propagated in Britain, and on the continent.

The largest tree on record, is at Schwöbber, near Hanover, in Germany. It had attained the height of eighty feet in 1835.

At Charleville Forest, in King's county, Ireland, there was, in 1835, a tree of this species, sixty years planted, which had attained the height of seventy-eight feet, with a trunk three and two-thirds feet in diameter, one foot from the ground.

At Taymouth, in Perthshire, Scotland, there was, in 1835, a Norway maple, fifty years planted, which was fifty feet high, with an ambitus, or spread of branches, of fifty-one feet.

This species was introduced into the United States by the late Mr. Prince, of Flushing, New York, prior to 1820, and is usually found in American nurseries and collections.

Soil and Situation. To attain a considerable size, this tree should be planted in a free, deep, rich soil, not surcharged with moisture; and the situation ought to be low rather than high. It thrives remarkably well along the sea-shore on the Baltic, and on the west coast of Norway.

Accidents, fc. The leaves of the Acer platanoides, in common with those of the Acer pseudo-platanus, and perhaps those of several other species of the same genus, are subject to what is commonly called the honey-dew, which, from its clamminess in the neighbourhood of the smoke of mineral coal, is apt to attract and retain the particles of soot that are continually floating in the air. In consequence of insects resorting to the leaves in quest of the honey-dew, they are frequently blackened with their excrement. This honey-dew, or manna, as it is called in some parts of France, is thought by some, to be produced by the extra
