"Trummying of the temples with floures, boughes, and garlondes, was taken of the heathen people, whiche decked their idols and houses with suche array.: Early church councils made rules and restrictions concerning the practice - e.g., in France Christians were forbidden "to decke up their houses with lawrell, yvie, and green gouches in the Christmas season," for "Hedera est gratissima Baccho." (The ivy is most acceptable to Bacchus.)

Leaf/Stem - slender and very much flattened sidewise. Leaf - two to two and a half inches wide, and usually about one half inch shorter than wide; dark green; smooth on both sides when mature, with a slight down on the edge. Ribs distinct above and below and whitish. Bark - of trunk, greenish-white and smooth, often with blotches of very dark brown, especially under the ends of the branches. The bark is exceedingly bitter. Found - from Northern Kentucky and the mountains of Pennsylvania northward to Hudson Bay and Newfoundland, northwest to the Arctic Ocean, and along the Rocky Mountain slopes. It is the most widely distributed of North American Trees.  General Information - A tree twenty to fifty feet high, with white, soft wood that is largely used in place of rags in making coarse paper. The tremulousness of its foliage, which the slightest breeze stirs, is due to the thinness of the sidewise-flattened leaf-stems. Tradition accounts differently for the motion of the leaves. It says that the wood of the aspen tree was taken for the Saviour's cross, and that, ever since, the tree has shivered. Another tradition claims that, when Christ went by on his way to Calvary, all the trees sympathized and mourned, excepting the aspen; but when he died, there fell upon the aspen a sudden horror of remorse, and such a fearful trembling as has never passed away. In describing the occupations of the fifty maidens in the hall of the "gorgeous palace" of King Alcinous, Homer says: "...some wove the web, Or twirled the spindle, sitting, with a quick, Light motion like the aspen's glancing leaves."

Fruit - a small four-celled prickly burr, splitting half-way to the base when ripe, and with two sweet, three-sided nuts in each shell.Found - in rich woods, Nova Scotia to Florida and westward, with it finest growth on the "bluffs" of the lower Mississippi basin. General Information - Large stately trees, with spreading branches and a delicate spray, fifty to eighty feet high. The wood is hard and very close-grained, and is used largely in the making of chairs, handles, plan-stocks, shoe-lasts, and for fuel. When the tree is not crowded, it sends out its nearly horizontal or drooping branches as low as from ten to thirty feet above the ground. Lumber-men make the distinction of "red Beech" and "White Beech," claiming that the former is harder, with a redder and thicker heart-wood.  Among woodsmen and the Indians, the Beech is said to be a favorite refuge in thunder-storms. They claim that it is scarcely ever struck by lightning. Lumber-men claim a difference in the quality of trees which retain their leaves and those which shed them. "Said a neighbor to me one day: 'You might 'a knowed that beech would split hard with all the dry leaves on it,' -- and it did. That was the first I'd ever heard of the sign, but I've never known it fail since."

The largest trunks are usually hollow.  The wood is hard and compact, difficult to split and work, of a reddish-brown color within. Its principle use is in the making of tobacco boxes. There is a fine and somewhat noted group of these trees on the grounds of James Know, in Knoxboro, N. Y. In old times they formed a favorite camping place for the Indians in their trading expeditions. They all measure not far from three feet in diameter. The name "sycamore," though a common one, should be dropped - it belongs to another and very different tree. From a Greek word meaning broad, in reference to the breadth of the buttonwood's shade or of its leaf.

Apex - long pointed (when there are side lobes their ends may be rounded). Base - heart-shaped, and more or less one-sided. Leaf - three to seven inches long, rather thin, rough above and downy below, sometimes becoming very smooth. The ribs are very distinct, and whitish below. Bark - grayish, and much broken. Berries - about the size and shape of small blackberries. When ripe they are very dark purple (nearly black), juicy, and sweet. July. Found - from Western New England, westward and southward. General Information - A tree fifteen to twenty-five feet high; in the Middle and Eastern States much larger. It is most common and reaches its finest growth along the lower Ohio and Mississippi rivers. Its wood is valuable, light, and soft, but very durable in contact with the ground. The White Mulberry (M. alba) is sometimes found around old houses and in fields. It was introduced from China, and was formerly cultivated as food for silk-worms. Its leaves resemble those of the Red Mulberry in shape, but are smooth and shining.

C. oblongifolia, T. and G., differs somewhat from the above in the dimensions of the flowers and flower clusters, etc. The name "shad-bush" is given because the trees blossom about the time that the shad "run".

Found - northward to Southern Newfoundland; southward to Florida; westward to the Black Hills of Dakota. Toward the western and southwestern limits it is found only in the river-bottom lands. General Information - One of the very noblest of American trees, eighty feet or more in height, and of strong and graceful proportions. The trunk divides at a slight angle into two or three arching limbs, and these again into many smaller curving and drooping branches. The trunk and the larger branches are often heavily fringed with short and leafy boughs. The tree is widely cultivated. Streets planted with it become columned and arched like the aisles of a Gothic cathedral. The wood is hard, and very tough from the interlacing of its fibers. It is used in making saddle-trees and for wheel-hubs, and is now largely exported to England to be used in boat- and ship-building. One day I found four men in a stone quarry, working with iron bars and rollers over a heavy flat slab. They were moving the stone slowly up a narrow plant into their cart. "John, " I said, "I would not think that board could hold a stone of such weight two minutes. Is it hickory?" "No sir, " said John, " that's an elm plank; it can't break." It did not break. It was one of the woods which the Deacon used in building his famous "one-hoss shay": So the deacon inquired of the village folk Where he could find the strongest oak, That count n't be split nor bent nor broke, - That was for spokes and floor and sills; He sent for lancewood to make the thills; The cross-bars were ash, from the straightest trees; The panels of whitewood, that cuts like cheese, But lasts like iron for thing like these; The hubs of logs from the Settler's Ellum; - Last of its timber, - they could n't sell 'em, Never an axe had seen their chips, And the wedges flew from between their lips, Their blunt ends frizzled like celery-tips;" --Oliver Wendell Holmes
