Putnam's Sons I said I will not walk with men to-day, But I will go among the blessed trees, — Among the forest trees I '11 take my way, And they shall say to me what words they please. And when I came among the trees of God, With all their million voices sweet and blest, They gave me welcome. So I slowly trod Their arched and lofty aisles, with heart at rest. Then all around me as I went, Their loving arms they lightly bent, And all around leaf-voices low Were calling, calling soft and slow.

DEAR SIRS : — I have been interested in glancing over the manuscript of Mr. Newhall's book on our native trees, and am much pleased to learn that it is to be published. There is great need of such a popular work. It will do much good in supplying information to our people about some of the common things around them, and this in an attractive manner. Yours very truly, N. L. BRITTON. LIST OF GENERA.

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. 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 arch- ing 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 fibres. It is used in making saddle-trees and for Fig. 23 Fig. 2.?. — White Elm. (U. Americana, L.j Fig. 23. — Slippery Elm. (U. fulva, Mirhaux.), NATURAL SIZE. 46 Trees with Simple Leaves. [A n 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 plank 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-boss shay" : " So the deacon inquired of the village folk Where he could find the strongest oak, That could 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 things 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. Corky White Elm. U. racembsa, Thomas. In foliage and shape and in the qualities of its timber this tree very closely resembles the white elm. A very noticeable difference is in its branches, which are often marked lengthwise with many large, corky, almost winged ridges. Its seeds resemble but are rather larger than those of the white elm. Pound, from Southwestern Vermont through Western New York and Southern Michigan to Northeastern Iowa, and southward through Ohio to Central Ken- tucky. Its finest growth is in Southern Michigan.

Apex, taper-pointed. Base, slightly heart-shaped or rounded. Leaf-stem, about one eighth inch long, stout and rough. Buds hairy. Leaf, four to seven inches long, three to four inches wide. The upper surface is rough both ways, and very rough downwards, almost like a fine file. The under sur- face is slightly rough. The ribs beneath are prominent and straight, and hairy in their angles. Bark of the larger branches, brownish ; branchlets, light- gray and very rough, becoming grayish-purple. The inner bark is very gummy and "slippery" Seeds, flat, round, winged, but not fringed. Last of May. Pound, along the lower St. Lawrence to Ontario, and from Western New England westward and south- ward ; in woods and along streams. A tree thirty to forty feet high. Its wood is hard and strong, but splits easily when dry. Though otherwise inferior, for posts it is superior to white elm. Its inner bark is sold by druggists as "slippery elm," and is nutri- tious and medicinal. Its name of red elm is due to the reddish-brown tinge of its large rounded and hairy buds in the spring. The English Elm [U. campestris, L.] was introduced early, and is often found in cultivation. It differs from the white elm, especially in these items : Leaves, usually smaller, and more closely placed upon the branch. 48 Trees with Simple Leaves. [An Bark, darker and much more broken. Branches, compact and more or less horizontal and straight to their ends, instead of arching and drooping. Seeds, resembling in shape those of the slippery elm. The tree is sometimes seen sixty to seventy feet high, but usually is much smaller. Like all the elms it is of rapid growth. Genus CELTIS, L. (Hackberry.) An ancient name for the Lotus.

Friiit, about the size of a pea ; solitary ; drooping from the bases of the leaf-stems, on stems once or twice as long as the leaf-stems ; rounded ; pulp thin, sweet, and edible ; purplish red ; ripe in September. Found, from the valley of the St. Lawrence westward and southward. A tree fifteen to thirty feet high (but much larger at the South), most common, and reaching its finest growth in the basin of the Mississippi. It is very variable in size and in the shape and texture of its leaves. Variety crassifblia is sometimes found, in which the leaves are thicker and usually toothed all around. Fig. 24. — Hackberry.

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 south- ward. A tree fifteen to twenty-five feet high ; in the Middle and Western States much larger. It is most common and reaches its finest growth along the lower Ohio and the 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. Fig. 25. — Red Mulberry.

Base, rounded or slightly pointed, rarely, in the small leaves, slightly heart-shaped. Leaf-stem, rough. Leaf, usually about five inches long, sometimes nine inches ; thick ; rough above, very velvety-rough. The main ribs are very distinct, and are thickly netted with smaller ones. Bark, light and smoothish. Flowers, in long aments and balls. Fruit, not edible. An introduced tree, common around houses or escaped from cultivation. A low-branching, large-headed shade tree of medium size, introduced from Japan. In Japan and China the bark of the Paper Mulberry is made into paper, whence the name. Leaves Alternate. 53 Genus PLATANUS, L. (Buttonwood.) From a Greek word meaning broad, in reference to the breadth of its shade or of its leaf.

Base, more or less heart-shaped, squared, or rounded. Leaf-stem, downy when young, smoothish when old ; and covering the leaf-bud with its swollen base. Leaf, three and a half to eight inches wide, and usually broader than long ; downy beneath when young, be- coming smooth. Bark, the thin outer bark peels off each year in hard and brittle strips, leaving the branches and parts of the trunk with a mottled, whitish, polished-looking sur- face. i Flozvers, small, in compact, round balls (about one inch in diameter) like round buttons, which dry and harden, and cling to the branches by their slender stems (three to four inches long), and swing like little bells during a good part of the winter. Found, from Southern Maine, southward and westward, in rich, moist soil, oftenest along streams. Its finest growth is in the bottom lands of the Mississippi and Ohio rivers. * The name " sycamore," though a common one, should be dropped. It belongs to another and very different tree. \ \ Fig. 26. — Buttonwood. (P. occidentalis, L.) NATURAL SIZE. Leaves Alternate. 55 The largest of the trees of the Atlantic forests, com- monly sixty to eighty feet high ; along the western rivers often eighty to one hundred and thirty feet high, some- times more, with a circumference of forty to fifty feet. A tree in Eaton, N. J., is one of the largest in the State. It is eighty-five feet high. At a point eight feet from the ground its circumference is fourteen feet three inches. 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 Knox, 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. Genus BETULA, L. (Birch.)

Outline, triangular. Apex, taper-pointed. Base, vari- able, more or less squared, sometimes slightly hollowed, rounded, or pointed. Leaf-stem, long and slender, about three quarters of an inch or more in length. Leaf, one and three quarters to three inches long. Smooth and shining on both sides. 56 Trees with Simple Leaves. [AII The outer bark of the mature trunk is chalky-white and thin, but not, like the bark of the Paper-birch, easily separable into layers. Usually it is marked with blackish dots and lines. Often the branchlets and twigs are blackish, and in very young trees the bark may be light reddish-brown, and marked with white dots. Found, on poor soil, from Delaware and Pennsylvania northward (mostly toward the coast), and in orna- mental cultivation. It springs up abundantly over burned and abandoned lands. A slender, short-lived tree, twenty to thirty feet high, with white, soft wood, not durable ; used largely in mak- ing spools, shoe-pegs, etc., and for fuel. A still more graceful cultivated species is the Eu- ropean Weeping Birch [B. pendula]. Its branches are very drooping, with more slender leaves, and a spray that is exceedingly light and delicate, especially in early spring.

Bark of trunk very tough and durable ; thick ; snow- white on the outside ; easily removed from the wood, and then itself very separable into paper-like sheets. The inner sheets are of a reddish tinge. Found, in the mountains of Northern Pennsylvania, New England, and far northward, farther than any other non-evergreen tree of America, excepting the aspen. A tree, forty to seventy feet high. The wood is light, hard, and very close-grained, but decays rapidly when exposed — more rapidly than the bark, which often remains as a shell long after the wood within has disappeared. It is very largely used in making spools, pegs, shoe-lasts, in turnery, for wood-pulp, and for fuel. The waterproof bark is much used by Indians and trappers for their canoes. " Give me of your bark, O Birch-Tree ! Of your yellow bark, O Birch-Tree ! Growing by the rushing river, Tall and stately in the valley !

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.

[Am It is very probable that the "Black Oak" and the "Scarlet Oak" ought to be considered as one, and de- scribed, not as species and variety, but as slightly different forms of the single species Q. coccinea. Though the most distinctive leaves of the " Black Oak " are easily recognized, often others are so nearly like those of the "Scarlet Oak" that it is not easy to distinguish between them ; and the same is true of the fruit and the bark. Michaux f. says : " The only constant difference between the acorns of the Scarlet Oak and the Black Oak is in the kernel, which is white in the Scarlet Oak and yellow in the Black Oak." The Gray Oak (Q. c., ambigua, Gray) is a variety sometimes found along the northeastern boundary of the States (as far as Lake Champlain) and northward.

" Give me of your balm, O Fir-Tree ! Of your balsam and your resin, So to close the seams together That the water may not enter, That the river may not wet me ! " And the Fir-Tree tall and sombre, Sobbed through all its robes of darkness, Answered wailing, answered weeping, 'Take my balm, O Hiawatha ! ' " Fig. 91 Fig. 90.— Balsam Fir.

Leaves, SIMPLE ; INDETERMINATE in position because of their smallness and closeness. They are arranged in four rows up and down the branchlets. In young or rapidly growing sprouts the leaves are awl- shaped or needle-shaped, somewhat spreading from the branch, very sharp and stiff, placed in pairs (or sometimes in threes), usually about one fourth of an inch long, and with the fine branchlets, which they cover, rounded. In the older and slower-growing trees the leaves are scale- like and overlapping, egg-shape, closely pressed to the branchlets which they cover, and with the branch- lets square. As the branchlets grow, the lower scales sometimes lengthen and become dry and chaffy and slightly spreading. Bark, brown and sometimes purplish-tinged, often shred- ding off with age and leaving the trunk smooth and polished. " Berries" about the size of a small pea, closely placed along the branchlets, bluish, and covered with a whitish powder. Found, in Southern Canada, and distributed nearly throughout the United States — more widely than any other of the cone-bearing trees. 1 82 Trees witk Simple Leaves. [c i An evergreen tree, fifteen to thirty feet high (much larger at the South), usually pyramid-shaped, with a rounded base, but varying very greatly, especially near the coast, where it is often twisted and flattened into angular and weird forms. The wood is very valuable, light, straight-grained, durable, fragrant. It is largely used for posts, for cabinet-work, for interior finish, and almost exclusively in the making of lead pencils. The heart-wood is usually a dull red (whence the name), the sap-wood white. Among the most picturesque objects in a Turkish landscape, standing like sentinels, singly or in groups, and as slender and upright as a Lombardy Poplar, are the black cypress trees (C. sempervirens). They mark the sites of graves, often of those which have long since disappeared. In America, more than any other northern tree, the red cedar gives the same sombre effect, whether growing wild or planted in cemeteries. The Common Juniper (J. communis, L.), common as a shrub, is occasionally found in tree form, low, with spreading or drooping branches, and with leaves re- sembling those of a young Red Cedar, awl-shaped and spreading, but arranged in threes instead of opposite.

Also about 1804 it was brought to Rhode Island from South America. But the source of most of the trees now found abundantly in the region of New York is Flushing, Long Island, where it was introduced in 1820.

Native in the Alleghany Mountains from Penn- sylvania (Monroe County — Porter) to Georgia ; but now very generally naturalized throughout the United States east of the Rocky Mountains. A tree usually forty to fifty feet high, sometimes ninety feet, and of rapid growth. Its wood is exceedingly hard and strong, and remarkably durable when in contact with the ground. It is used largely for posts, in ship-building, and in turnery, and it is preferred to all other native wood for treenails. It is one of the most valuable trees of this or of any country. But its cultivation as a timber tree, which at one time was very general, has nearly ceased in the United States on account of the constant damage o done by the grub of the Painted Clytus (Clytus pictus). This troublesome borer not only injures the new growth, but also pierces and detaches large branches, leaving the tree ragged and stunted. Clammy Locust. R. viscbsa, Vent. This species is native to the high ranges of the southern Alleghany Mountains, but is now very widely cultivated and sometimes naturalized in the Atlantic States. It differs from the common locust especially in its smaller size, in having its leaf-stem and branchlets "sticky" and slightly rough, and its flowers rose-tinted and scarcely fragrant, and in close and erect bunches.

The wood is very soft and brittle ; yellow within ; the sap-wood white. The young shoots, with the pith removed, are used in the spring as " sap quills" in drawing the sap from the sugar maples. The downy and irregular branchlets are suggestive of the horns of a stag, whence the name. An infusion of the berries is sometimes used as a gargle for sore-throat. This species is not poisonous.

[D n Found, from Northern New England westward and south- ward, oftenest in swamps. A small tree (or more often a tall shrub), six to eighteen feet high. It is violently poisonous to the touch, causing in most persons a painful eruption ; some are poisoned by it without touching it ; probably by rea- son of the drifting pollen of its flowers. A recommended application is sugar of lead, applied after the use of saline cathartics ; or a thick paste of bicarbonate of soda rubbed into the skin as soon as the eruption appears. It is also claimed that relief and, if used promptly, frequent cure follow the use of belladonna, of apis mellinca, or of arsenicum album — taken in homoeopathic doses. Apart from other differences the Poison Sumach can be easily and quickly distinguished from all the other sumachs by these signs : It differs from the Stag-horn Sumach and the Smooth Sumach (a shrub) in having the edge of its leaflets entire ; from the Dwarf Sumach (a shrub) in the absence of the winged stem between its leaflets, and by its red leaf-stem.

Found, from Labrador and Newfoundland through the Northern States and southward along the Alleghany Mountains. Its finest growth is on the northern shores of Lake Huron and Lake Superior. A slender, somewhat pyramid-shaped, tree, ten to thirty feet high, much and justly prized as one of the best of the native trees for ornamental planting. Its bark and the unripe fruit are very astringent, and are sometimes used medicinally. A slightly different species (P. sambucifolia) is some- times found in cold swamps and on the borders of streams, along the Northern frontier. The cultivated European Mountain Ash or Rowan Tree [P. ancuparia], which is very common in many parts of Europe, and especially in the Highlands of Scotland, differs but slightly from the American Mountain Ash. It varies chiefly in the following items : Leaflets blunter, and rather coarsely double-toothed. Bark rather rough. Fruit larger, oftenest red, but sometimes orange. Leaves Alternate. 203 The Mountain Ash or " Rowan Tree" has for a long time been renowned as a safeguard against witches and all evil spirits. A mere twig of it suffices.
