The necessity of more generally diffused infornmtion concerning the variety and importance of our forest trees is 'justification enough for the ap])earance of this work, especially at this day, when the demands of Forestry in this country are constantly more and more keenly felt. The work was undertaken at the suggestion of my fatlier, whose intense in- terest in Forestry, and a kindred taste, at once gave me inspiration to the work. It was entered upon with tlie expectation of his valuable com- panionship and counsel during its progress, but, alas ! that I was destined to have only at the outset, and, while I was then left ever to mourn the loss of a kind father, companion and teacher, the reader must fail to find _u these pages that value and finish which his mind would have given them Among the happiest pictures of my memory are those in which I see my father's delight, as I would show to him, from time to time, my suc- cessful progress in devising a way of making tlie st^ctions for tiiis work, and if only for the happiness which its appearance would have caused him, could he have lived until this day, I have felt duty-bound to go on with it, even though left to do it alone. The work is the outgrowth of one, of somewhat similar plan, jiropi-sed by my father some years since, but which he did not carry into effect. Its design is primarily and principally to show, in as compact find perfect a manner as possible, authentic specimens of our Amcriian woi.ds, both native and introduced. For that end three sections, respectively transverse, radial and tangential to the grain \see Glossary), are made of each timber, sufliciently thin to allow in a measure the transmission of light, and securely mounted in well made frames. The three jilanes above mentioned show the grain from all sides, so to speak, no plane being iM)ssil)le but that would be either one of them or a combination of them. The difficulty, hov/ever, of cutting a great number of sections exactly on those planes is obvious, so let it be under- stood that the terms, "transverse," '"radial " and " taiigcurial," are, in many cases, only approximately exact in their application. My enaeavor is to shovv. either in a part or all oT tlie sections standing to represent a species, both the heart and sap-wood, but with some woods vi Preface to the Seribs. as the Sumach, for instance, wiiere usually only the outermost ring, or a part of it, could be said to represent the sap-wood, the display of that is quite impossible. In certain other woods, as the Spruce, etc., the tran- sition from sap to heart-wood is almost indistinguishable by any difference in color, and, although both may be shown in the sections, one can scarcely distinguish between them. Tlie sequence of the Jiumbers given to the various species is of import- ance only to show the botanical arrangement within a given Part, each Part beiiig independent of the others. The text of this work has been added rather as a secondary matter, to supply to those not having it in other form, such information as is of importance, in connection with the wood specimens, to give a fairly good acquaintance with the trees represented. It contains little, if any thing, new to the botanist, but to others it is hoped it may be of some value. In its preparation some use has been made of my father's Elements of Forestry, and thanks are due the publishers of that work — Messrs. Robert Clarke & Co. of Cincinnati, Ohio — for the use of cuts in repro- ducing a number of its illustrations. Other valuable books of reference have been the works of Drs. Gray, Wood and Bessey, LeMaout and Decaisne's Descriptive and Analytical Botany, Prof. C. S. Sargent's Report on the Forest Trees of North America (constituting Vol. IX, Tenth Census of the United States, 1880), Micheaux and Nuttall's North American Sylva, George B. Emerson's Trees and Shrubs of Massachu- setts, D. J. Browne's Trees of America, etc. The authenticity of the timbers represented in this work has been a subject of personal attention and special care on the part of tlie author. The trees selected for specimens have been identified in the field, before felling, while the leaves, flowers or fruit (one or more) have been obtain- able, and lie can, hence, vouch for the authenticity of every specimen represented. Succeeding Parts, uniform in style with Part I, and representing in each case twenty-five additional species, are planned to appear later, with the ultimate end in view of representing, as nearly as possible, all of the American woods, or at least the most important, in such a series of vol- umes as (his one. Upon tho reception which this meets in public favor, and upon the co-operation of those interested in the cause, must naturally depend the carrying out of that plan. It is hoped that greater experience and skill will enable us to obviate in future parts the faults which occur, from lack of those qualities, in this. Notice of errors in this work will be thankfully received in hopes of profiling therefrom in the future. LowviLLE, N. Y., March 30, 1888. PREFACE TO PART VIII. Part YIII, American Woods, is tlie tliird installment of the woods of the Pacific slope, and in the announcement of its completion I feel a special pleasure in that I am able to show in it the interesting wood of a palm. The successful sectioning and representation of palm woods has long been an unsolved problem with me, and not until my recent experiments with the California Fan Palm have I met with any success in its solution. The result of our experiments is shown in the accompanying sections. Another gratifying success is shown in the sections of the wood of the Cactus, Opuntia Tuna. This, too, is a wood whicli we took up hardly expecting to succeed with it. The result was a happy surprise and the sections were found to be most interesting. The sections of the Palm and Cactus are so fragile that we have found it necessary to protect them with mica, which I trust will be sufficient, and I feel confident that their appearance in American AV^oods will be welcomed by our patrons with as much pleasure as we include them. I am pleased to acknowledge gratefully the assistance rendered by Mr. Samuel B. Parish, Mr. Chas. H. Shinn, Dr. H. E. Hasse and others while gathering the woods. For the privilege of collecting specimens of the interesting woods on Santa Catalina Island I am under obligation to Mr. J. B. Banning, and for courtesies and valuable assistance in the work to Mrs. Blanche Trask and Mr. W. S. Lyon. I wish also to acknowledge with sincere thanks the courtesies extended by Pres. C. P. Huntington, of the Southern Pacific Railroad Company, which have greatly aided me in my work. LowyiLLE, N. Y., July 31, 1899.

Species whose AVoods are Represented in the AccoM' PANTING Sections. The timbers comprised in the series which this text is designed to accompany belong to what are known, botanically speaking, as Floicering and mostly Exogenous Plants. At the outset, therefore, we will, once for all, define these groups; and, as the characters herein given are equally true of all the species enumerated in the fob lo\ving pages, they need not be repeated in the further definition of the various sub-groups and species. FLOWERING or PH^NOGAMOUS PLANTS. Plants producing flowers which consist essentially of stamens and pistils, the latter bearing ovules or seeds. In distinction from the Flowering Pla.rds are the Flowerless or Cryptognmous Plants, comprisinj!; the rest of the vegetable kingdom, from the very simply- organized SUme Moulds and Bacteria up to the highly organized Ferns and Club Mosses. But in the study of timbers this group is unimportant, as only in a few rare cases do any of its representatives attain the dimensions of trees. Those exceptions are the Tree-Ferns of tropical countries — gigantic ferns, which some- times attain the height of fifty or sixty feet, with straight shafts quite like tree trunks and tops consisting of a bunch of enormous plume-like fronds. They, however, are of practically no value as timber. EXOGENOUS OR DICOTYLEDONOUS PLANTS. Flowering plants whose stems consist of a central colimin of pith surrounded by wood in concentric layers, and this in turn by bark ; the stems increasing in thickness by the addition of a new layer each year to the wood externally and to the bark internally. Leaves mostly netted-vein. First leaves of the embryo (cotyledons) two and opposite, or (in the Coniferje) several in a whorl. Parts of the flower in fours or fives, very rarely in threes. 24 Hough's American "Woods. A second class of Flowering rinnta and comprisinfj: tho rest of the group is the Endogenous or Monocofiilcdouoits I'lmifs, cliarartt'ri/.cil hy liaving stems in which the wood occurs as threads or bundles running tlirough a Cflluhir, pitii-like tissue 8o that a transverse section exhibits the wood as dots and not in concentric rings. Leaves mostly parallel-veined. Embryo with single cotyledon, or rarely two. and then alternate and unequal. Parts of the flower generally in threes. In southern United States and elsewhere in or near the tropics trees are found, such as the Palms, etc., which belong to this class, but none we have to do with at present. Exog(!nou8 plants are subdivided into two well -marked groups or sub-classes — Angiospermce and Gymnospermce. The former includes by far the greater part of the Flowering Plants, and most of the species represented iu " American Woods " are representatives of it ANGIOSPERM^. Flowering, exogenous plants in which there is a complete pistil — with stigma and closed ovary — containing ovules which develop into seeds at maturity. This sub-class comprises many groups of plants known as Orders, and such as are represented by plants which attain the dimensions of trees, within the limits of the United States, we propose to consider in the following pages : Order RHAMNACEAl: Buckthorn Famh^y. Leaves simple, mostly alternate and with stipules small or wanting. Floivers small, often polygamous and sometimes dioecious ; sepals valvate in aestivation, small, distinct, concave and involute in the bud or wanting ; staaiens as many as the petals and opposite them, inserted with them in the edge of a perigynouB disk lining the calyx-tube, short and sometimes connected with the lower part of the ovary ; pistil solitary, with mostly superior ovary, 2-5 celled, each cell with a single erect anatropous ovule ; stigmas 2-5. Fruit a drupe or pod with one seed in each cell and not arilled ; embryo large with broad cotyledons and sparing flieshy albumen. Order represented by small trees and shrubs of warm and temperate countries, with slightly bitter juice and often nauseous or purgative fruits. Genus RHAMNUS, Linnaeus. Leaves mostly alternate, pinnately veined, entire or dentate, petiolate, condupli- cate in vernation; stipules small and deciduous. Floivers small, greenish, in axillary racemes or cymes, ])olygamous or dioecious ; calyx campanulate, the tube lined with the disk, 4-5 cleft, the lobes keeled within antl deciduous ; jietals small, with short claw, more or less notched at apex and turned in aroimd the Btamens, deciduous ; stamens with very short subulate filaments and introrse 2-celled anthers opening lengthwise ; pistil free, with 2 4-lobed stigma and 2-4-celled ovary, each cell containing a solitary, erect, anatropous ovule. Fruit a globose or oblong, blackish. berry-Hke drupe, with fleshy epicarp, and containing 2-4 cartilaginous. 1-seeded nutlets; seeds longitudinally grooved on the back. Trees and shrubs of considerable economic importance, and the name, Rhamnus, is the classical Greek name, ^d|ivos, of the European Buckthorn. TliiAMxus ixsii.AHis — Island Blckthorx. 25 176. RHAMNUS INSULARIS, Ctukksk. Island IUckthorn, Island Bearwood. Ger., Ell dnd'i. seller Kivnzdorii ; Fr. , y^erprun hisulaire ; Sp., Iiff/nno d<' isla. Specific Characters :• — Leare.s altercate, persistent, ovate-oblong, 1 to lA and sometimes 3 in. in length, coriaceous, glabrous or sparingly pubescent, about equally pointed at both ends, minutely glandular crenate-serrate with short stout petioles and straight prominent mid-ribs, yellowish green, paler and frequently yellowish beneath : stipules faUing away early ; new growths'sparingly pubescent. Flowrra four-nunierous, dioecious, greenish, in small clusters from the axils of the leaves on the shoots of the year, or of small bracts, with slender sparingly pubescent pedicels rather more than i in. in length ; calyx canipanulate with acuminate lobes ; petals wantmg (tiiough according to Prof. Trelease are some- times present) : stamens with stout incurved tilaments and large antlers : pistil with ovoid ovary ami rather slender style two-lobed above. Fruit red. subglo- bose, about I in. or a tritie more in length, slightly grooved, with thin, dry flesh and containing 1-8 ovoid nutlets pointed at the apex, dehiscent along the inner angle, grooved on the back, with thin bi'own testa and thick foliaceous cotyledons. {lusiilaris is the Latin for belonging to an island and relates to the habitat of the species.) A small tree with rio;id branches, rarely more than 25 ft. (7 m.) in height, with trunk sometimes 12 in. (0.30 m.) in diameter and having a dark l)rown l)ark abont ^ in. thick and rough with small, iirm, irregular scales and ridges. Habitat. — The islands off the coast of southern California, Santa Cruz Mountains on the adjacent mainland and Cedros Island off the coast of Lower California, growing along slopes with Scrub Oak, whicli it considerab'ly resembles in general aspect, Ceanothus afhoreiis, etc. Physical Properties. — Wood very heavy, hard and close grained, with very line regularly arranged ducts, susceptible of a very smooth polish and of a rich red-brown color with scant yellow sap-wood. Uses. — We know of no use to which this small tree is applied, though the bark might be used for dyeing purposes, as with other representatives of the genus, and the wood would make excellent fuel. Medicinal Properties we believe have not been reported of this species, but would doubtless be found to be tonic and laxative as with other species of the genus. Rhamnns hiftularis, Greene, is considered by some botanists as a variety of lihamnus erocea, jVutt., {Rhamnufi crocea insularh, Sa/'(/.), 1)ut it is certainly a well-marked form differentiated from the true R. crocea i)y characters as important as distinguish many otliet species, and I am inclined to agree with Prof. Greene in giving it specific rauk. Hough's Amkrican Woods. Genus CEANOTHUS, Linnaeus. Leaves mostly alternate, petioled. coriaceous or somewhat so, glabrous or vari- ously pubescent, deciduous or persistent, with slender stipules falling away early, Floicers perfect, in showy terminal or axillary thyrsoid or cymose clusters, blue or white and with colored pedic-els ; calyx colored. 5-lobed, cohering witli the ovary below, the triangular lobes incurved and deciduous ; petals much exserted. hooded, spreading, witii long slender claws : stamens 5, opposite the petals and inserted with them, spreading and often persistent, with long filaments anti introrse 3-celled antiiers longitudinally dehiscent ; pistil with three short styles united below and single 3-celled and usually 3-lobed ovary surrounded with a fleshy persistent disk and containing a single erect orthotropous ovule in each cell. Fruit subglobose, 3-lobed. drupe-like at first, with persistent calyx-tube adnate at base, finally becoming dry and separating into three 2-valved dehiscent cocci each liberating a single obovate lenticular seed with thin crustaceous testa, ventral raphe and fleshy albumen. The genus is composed of about thirty species, mainly of shrubs, and is confined *^^o North America, the greater number being found in California where some natural hybrids seem to occur. The name is of classical Greek origin and of ratner obscure application. 177. CEANOTHUS ARBOREUS, Greene.* Tree Myrtle. Ger., Baiimisehe Myrte ; Fr., Myrte d' arhre ; Sp.. Mirto de Arhol. Specific Characters : — Leaves alternate, ovate to broad elliptical, 2-4 in. long, acute, rounded at base, glandular cienate-serrate, dark green above, and with pale dense short tomentum and inominent veins beneath : petioles i-| in. in length and, as with the new growtlis, (iensely i)ale-toinentose; stipules about i^ in. long and early deiiduous -. branchlets slightly angled. Flowers pale blue, produced in ample <(iin|M.uii(l lHiary-i)nl)es(eiit tliyrsoidal clusters on axillary peduncles near the extieinities of youiig l)ranches, with slender hair-like pedicels produced in the axils of large »carious hoary caducous bracts. Fruit black when mature and i in. in diameter. (Arboreus is a Latin adjective from arbor, tree.) Tlii.-^ is a small liaiidsonie tree with wide top, rarely over 25 ft. (7.50 111. ) in lieiiilit, or with trunk more than 10 or 12 in. (0.30 m.) in diameter. The hark, at tirst of a gray color and quite smooth, becomes with age of a dark hi-owii color lissured into small square thickish scales. It is the most truly arboreal representative of the genas, though in many regions is only a bush with many slender branches. Habitat. — The islands of Santa Catalina, Santa Cruz and Santa Rosa, off the coast of .-outhern C^difornia, growing along the slopes and sides of canons. PiivsicAi, Properties. — Wood very heavy, hard, close-grained, with annual layers marked by an aggregation of tine open ducts, and of a red-brown color with lighter sap-wood.

The wood is doubtless excellent for fuel. Medicinal Properties. — We do not know that the medicinal properties of this species have yet been studied. Order ANACARDIACEiE : Cheshew Family. Leaves alternate, simple or coiupound. without pellucid dots : stipules none. Flowers polypetalous, small, often polyganunis, regular and furnished with bracts ; sepals '6-r>, united at the base, persistent ; petals o (or sometimes wanting), imbricated in the bud ; stamens 5 or 10, alternate with the petals and perigynous, ovary free, 1-celled and 1-ovuled : styles or stigmas 3. Fruit a berry or drupe, the seed containing no albumen. Trees or shrubs with a milky resinous or gummy acrid juice, which, as well as the exhalations, are often poisonous. Genus SCHINUS, Linnaeus. Leaves evergreen, alternate, unequally pinnately compound, with sessile leaf- lets. Flowers, small, whitish, dioecious, in laige axillary terminal bracteate panicles ; calyx short, with 5 imbricated lobes ; petals 5, imbricated, annular disk rather broad ; stamens 10. styles 3: ovary 1-celled with single ovule suspended from above the middle of the cell. Fruit, small globose oily drupes. A genus of trees and shrubs of about a dozen mostly tropical American species and the name. Schinus, is the old Greek name, o-xivos, of the Mastic-tree, applied to tliis genus on account of the mastic-like juice which exudes from its various representatives. 178. SCHINUS MOLLE, L. Pepper-tree. Chili Pepper. False Pepper. Ger., Pfefferhainn ; Fr., Poivrler faux ; Sp., Phniento falso. Specific Characters : — Leaves 8-12 in. long, of numerous (13 or 15 or more) pairs of remi)te and irregularly disposed lanceolate sessile entire or remotely ser- rate leaflets, the terminal one longest; leaves and new growths generally" very thinly coated with agummj- exudation. Flowers (in Feb. and Mar. in California) in large pendent tbyrses. small yellowish green, terminating the long flexuous branchlets. Fr?nY small drupes scarcely as large as peas, beautifully rosy-cheeked, of strongly pungent flavor and hanging in long loose clusters. The specific name, Molle. is a modification of the Peruvian name of the species MuUi. A tree sometimes 3 or -1 ft. (1 m.) in diameter of trunk, with rather irregular, wide top, of few large branches and long, gracefully pend- ent branchlets. It is a very handsome tree in all seasons of the year, with its drooping graceful habit and airy evergreen foliage, but when bedecked with its many clusters of light-red fruit lianging from the tip of each branchlet it is of very striking and beautiful appear- ance. The bark of trunk is of a grayish-brown color and with age becomes split into many longitudinal and obliquely connecting, firm, fibrous ridges. 28 Hough's American Woods. Habitat, — The Schinus Molle is a native of tropical America, Mexico to Brazil and Peru, but has been extensively planted in warm countries elsewhere for ornamental purposes. The climatic conditions of southern California seem thoroughly congenial to it and it has there been vei-y extensively planted, becoming naturalized in places. Physical Properties. — Wood rather soft, light, tough, with obscure layers of growth, fine medullary rays and quite regularly dis- posed bands of fine ducts. It is of a mottled brown color with coi)i- ous pinkish or brownish- white sap-wcod. Uses. — Almost the exclusive use of this tree with us is for orna- mental planting, for which it is justly very popular. It is found ornamenting the streets and door yards everywhere throughout south- ern C'alifornia where it grows rapidly and attains its largest size. In that region it is now a feature of almost every snl)url)an scene. The trees when felled make fairly good fuel. Medicinal Properties. — The leaves and bark and the gum-resinous exudation have been employed medicinally. Tlie fruit has been used successfully in the treatment of gonorrhoea, as a substitute for culjebs.* It also possesses purgative properties. Note. — When fragments of the fresh leaves of this tree are placed in water they move about by jerks as they float upon its surface, as though animate objects possessed of an ability of voluntary motion. This motion is caused by the bursting of glands in tlie tissues and tlie discharge tlierefrom of a volatile oil. Genus RHUS, Linnaeus. Leaves alternate, mostly compound (rarely simple) without stipules.

(The specific name is from the Latin integer, entire, and folium, leaf.) A small evergreen tree with low wide top of strai;-oliiiir branches, the lowermost often reclining upon the gronnd, and all forming a dome of foliage. In its center is found a short thick trunk, some- times 2 or 3 ft. (O.T m.) in diameter, covered with a reddish-gray bark which flakes olf in rather small irregular scales. It sometimes attains the height of 30 ft. (9 m.). It is commonly only a wide impenetrable bush, and when in exposed places close to the coast seeming like a bank of foliage smoothly trimmed from the ground up, and when these banks are bestrewn with its many waxen rose- colored panicles of honey-scented flowers, or later with its hunches of viscid red drupes, it is a very handsome object. Habitat. — This Sumach is found along the Paciflc Coast from near Point Conception into Lower California, and on some of the off-lying islands, attaining its greatest development in Lower Cali- fornia. Physical Properties. — Wood heavy, hard, strong, with flue grain and susceptible of a smooth polish ; the heart is of a salmon pinkish color, lemon-yellow near the thin white sap-wood of eight or ten annual layers.

They Avere quite generally planted about mission walls in southern California in early days, and we can imagine invading Indians must have considered it worse to pass than the adobe wall itself. The plant has also been used extensively for hedges in southern Europe, and we learn that when the Island of St. Christopher was to be divided between the English and French three rows of this cactus were planted by common consent along the boundaries. The fruit is edible l)ut unless the numerous minute hair-like prickles are thoroughly wiped off and rind removed before ti^dng to eat it the barbed prickles are sure to become lodged in the lining of the mouth and annoy one for some days after This is a favorite species of Cactus for supporting the cochineal insect, an industry principally of Mexico, Central America and the Canary Islands. Medicinal Properties are not recorded of this species. Order CORNACEiE : Dogwood Famly. Leaves opposite (except in one species) simple, mostly entire.

Flowers monoe- cious or dioecious, sometimes without floral envelopes; calyx, if present, gamo- sepalous ; corolla poly{)etalous or monopetalous, liypogenus or perigenous, or commonly wanting, imbricated or twisted in a?stivati(>n : stamens 1 to many with globose or dulymous anthers : pistil witli free usually 3-celled ovary (rarely 1 to 2 or several-celled) with a single or pair of anatropous ovules suspended from the summit of each cell. Fruit a capsule mostly 3-celled and :Mobed, the lobes elastically separating from a persistent axis and then loculicidally splitting into two valves ; seeds anatropous, crustaceous, with large straight embryo, broad cotvledons and rather scant albumen. 44: n< iron's A^lkricax Woods. A very large and important order of over 3,000 species of lierbs, slirulis and trees, usually with ii^ilky, acrid juice. About half of the representatives belong to tropical America and some yield valuable medicines, others active poisons and others important foods. GENUS RICINUS, Tourxefort. Leaves alternate, large (often a foot or two acro.ss) peltate and palmately seven to many lobed. lobes unecjually serrated. Floirers monoecious, disposed in long, glaucous, sub- paniculate racemes at the ends of the branches, short pediceled, the staminate clustered above pistillate flowers ; calyx in the staminate flowers closeil in the bud, in the pi.stillate sheath-like, cleft and very caducous ; petals wanting in both sorts of flowers: stamens very numerous, with crowded branched filaments, each branch bearing two separate roundish anther-cells ; ovary 3-celled with 2-cleft plumose styles and a single ovule in each cell. Fruit a subglobose smooth or prickly capsule, hardly 1 in. in diameter and dehiscent septicidally from tlie base into three cells (cocci) which in turn are dehiscent loculicidally and from each is liberated a large compressed oblong seed, with smooth crustaceous brown and white testa, terminal hilum, fleshy albumen and broad flat cotyledons. A genus of the single following species (of which, however, there are several garden varieties) and the name, Ricinus, is the ancient Latin name of a tick which insect the seeds of this plant are said to resemble. 189.

This is used chietly in medicine, hut is also valuable as a lubricant and formerly was used as a luminant. Some years ago the streets of Lima, Peru, it is said, were lighted by it, and the machines used in the works of the sugar plantations of Peru were lubricated by it. Tlie Castor Bean is very popular for ornamental gardening for wiiich it is admirably adapted, as it springs (piickly from the seed and soon becomes a large and beautiful plant of tropical aspect. Medicinal Properties. — Castor Oil, expressed from the seed, is a mild and speedy cathartic, decidedly the best and safest cathartic, as a general rule, for children. Order JUGLANDACEiE : Walnut Family. Leaves alternate, pinnate and without stipules. Flotcers monrecious and apetal- oup. excejit in some cases in the fertile flowers.

Uses. — The wood is not extensively used, though sound trunks, when large enough, are suitable for sucli uses as the allied Black Walnut is applied, as in cabinet making, etc. It is often planted as a shade tree. The fruit, though small, is considered, by cliildren at least, as well worth gathering on account of the good edible qualities. They are sometimes })lanted as young stocks on which to graft the English AValnut.

The specific name, Wish'zeui, is given in compliment to Dr. F. A. Wislizenus. an eai-ly botanical explorer who gathered the type specimens on which the species was founded. This beautiful tree attains the height of 75 or 80 ft. (24 m.), with round wide close top of strong spreading branches and dense dark green foliage. The trunk, which is generally short, is occasionally 5 or fi ft. (1.5(1 m.) in diameter, and its bark is of a dark brown color, ridged longitudinaliy and covered with firm closely ajij^ressed scales. It is a handsome tree and adds not a little to the charms of tlie land- scape scenery in the regions in which it abounds. Habitat. — California — from IMount Shasta southward along the foothills of the Sierra Xevada Mountains to the Tehachapi ^NEountains and among the Coast ranges as far south as Santa Lucia ]\rountains. In its tree form it is confined to the interior, back some distance from the sea, being supplemented near the coast by the Quercus agrifolia, a tree of very similar aspect and with which it was at first confounded.

It is planted sometimes in oui- southeastern states, in South America, Australia, and extensively in southern and western Europe. Note. Visitors to the home of the ^Monterey Cypress are often told by the people residing thereabouts that " this tree is only found PiNUs >[oxopnYLLA— Single-leaf Pinox Pink. 55 lierc and in the Holy Land." This is an error. The tree in the Holy Land t(» which reference is made in this statement is the Cedar of Lchanoii {Ct^/i'us Libani), very different, of course, from the Cypress hitanically, though its habit of growth is so similar to that of the tiat- ropped Cypress trees of Cypress Pouit that it has given rise to the ])opular helief, among people not particularly versed in trees, that they are the same.

Uses. — The wood of this tree has been used for fuel, and its large seeds, which are rich and delicious in flavor, are often gathered and eaten raw or roasted. Note — The inroads upon this tree for fuel by irresponsible people residing near it has been so great that its extermination has been greatly feared, hut fortunately the city of San Diego has recently pas.sed an ordinance jn-ohibiting the cutting of any of the trees within the city limits under penalty of a heavy fine. As most of the existing trees are in the city limits, as now extended, it is reasonable to expect that the species will be perpetuated at least for a long time to come in its native home. 58 Hough's Amkrican Woods. 198.

Uses. — Wood very inferior for lumber and fuel; hence but little used. The delicious edible nuts in early days were an important article of food with the Indians of California, known as Digger Indians, and from that fact it derived its common vernacular name, Dio^o'er Pine. Medici XAi. Properties. — A volatile oil is distilled from the resin- ous exudation of this tree and is extensively used in California under the name of (d>'u'tene and other less appropriate designations (as erasine, auraiitine and theoJine'). It is a nearly colorless liquid, with the odor of oil of Oranges, and is believed to possess powerful anaes- thetic properties. Its value in medicine has probably been. over- estimated, though it is extensively employed for removing grease spots and stains from clothine;, and to some extent as an insecticide.* 199. PINUS RADIATA, Don f Monterey Pine. (rer., Fichte von Monterey ; Fr., Pin de Monterey; Sp., Pino de Monterey. Specific Characters: — Leases from 4-6 In. long, in clusters of three eacli; slieatlies at first loose, scarious and from i to f in. long, but finally firmer, darker colored and onh' ^ in. long, leaves serrulate, stonatiferous on three faces, with two fibro-vascular bundles and usually a single liarenchymatous resin duct. Staminate flowers in densf cylindrical (iblong spikes 1 to U in. long, with ten involucral bracts and yellow anthers terminatijig in orbicular denticu- late crests. Pistillate flowers lateral, generally several together in a whorl on short stout bract-covered peduncles, dark purple, with, ovate slender-tipped scales and conspicuous orbicular bracts. At tlie end of the first year the young cones are nearly horizontal, ovoid, about 1 in. or less long and with niinute incurved spines. Cones wlien mature are 8 to 5 in. long, lustrous chestnut brown, short-stalked, very .ililicjue-ovoid, pomted at apex, deflexed, with scales rounded at tlie ai)ex. piu-ple beneath, the exposed portion of the scales on the outer side to\v;ir; Tichitli'e Approximate F'lit J VuJik, ; Moditlns of R>i2>tiir<\ 74(»; lusisf- (otce to LoiKjltud'mol Pt'esNKi'e, 417; Jtc-^isto/in' to Jmlentat'ion^ Ic."): Wchjld of a Cuh'ic Foot hi Povnds, 2S.51. l'si;s. — Formei'ly the ]\[onterey l^ine M'as used foi- hnnber, bur now it is only ut^cA to a limited extent tor fuel. The tree is very extensively ])lanred for ornaiuiMital j)urposi's and wind-bi-eaks. for which it is admirably suited, owing to its rapidity of growth and ada])tability to conditions of soil and climate. In this respect it re.sendtles the ]\[onterey Cypress, whicli, strangely, hails from the same li-itish possessions to southern Cali- f(U'nia. It is also successfully ])lanted in the southeastern states, ]\rexico, Australia ami New Zealand, and has long been ])0])ular in M'estern and southern Europe.

Flc^wt-rin,-; plants, in the steins of which the -.voody fibers an.l vessels are irregu- larly imbedded in bundles in cellular tissue (not in annual layers). The leaves are" mostly parallel-veined, sheathing at the base, alternate or scattered, not toothed and rarely separating by an articulation. First leaf of the embryo ^coty- ledon) single and the parts of tiie flower generally in tln-ees. FALM.^ : Palm Family. Leares flabellate or pinnately divided, rarely simple, springing from the ter minal bud, alternate and with base slieathing the stem. Floicers usually diclinous, on a branched spadix : perianth of six herbaceous segments in two rows ; stamens six ( rarely fewer or more) hypogynous or perigynous ; pistil with superior 3- (rarely if celled ovary of three separate carpels with a single or rarely 2 ovules ia each cell; styles short, free or connate. Fruit commonly a berry or drupe, with large seeds having a minute peripheric embryo in tiesliy or horny albumen. The order consists of upwards of 1.000 species of perennials — trees and shrubs — of tropical and subtropical regions, of elegant or majestic habit of growth and many of tiiem of great economic importance. Their stems present the typical endogenous structure, the wood forming in dense wire like bundles, known as fibro-vascular bundles, between which is a mass of thin walled pith like cells known as parenchynm. The woody bundles are crowded more closely together toward the peripliery of the stems, which is generally tiiere (juite hard in con- sequence and the central portion is comparatively soft. There is no true bark on these stems nor is there a central pith column as with exogenous stems. Genus Washixgtoxia, Wendlaxd. Leaves fiabellate, orbicular, plicate in vernation, deeply divided into many 2-eleft segments, from tlie margins of which hang numerous pale thread-like fibres, and at the union of the petiole with the blade above is a thin elongated laciniate ligula; petioles long, broad, with margins armed with strong, variously hooked and straight wide-ba.sed but thin spines, the base of petiole widening out and margined with a broad fabric-like chestnut-brown network of strong fibres. Flowers perfect, small, white, from the axils of ovate acute scarious bracts, on elongated paniculate glabrous spadices, which appears from among the leaves with numerous flexuose [lendulous branches; spathes luimerous. narrow, elon- gated, glabrous; calvx tubular, scarious. with tln-ee small eroded lobes, indurate at base, persistent, imbricated in ajstivation; corolla funnel-sliaped with fleshy tube half as long as the three lanceolate acute striate reflexed lobes, imbricated in aestivation, deciduous; stamens usually six. sometime three or many, exserted. with free filaments thickened below the middle, slender at apex and bearing linear-oblong 2-celled versatile pale yellow anthers, attached on the back and longitudinally dehiscent: ovary superior, sessile, 3-lobed. 3-celled, with elongated flexuose exserted style, stigmatic at apex and containing a single lateral erect anatropous ovule "^in each cell. Fruit drupaceous, small, blackish, globose-elliptical, sliort stalked and crowned with the remnants of the style and abortive carpels, the fleshy pericarp thin and sweet, and the seed oblong-ovoid, with minute sublateral hilum, conspicuous raphe, thin brown testa, hoi-ny albu- men and minute lateral embrvo. Genus composed of two species; one. found in California and the adjacent regions of Lower California, is described below, and the other, WasJiiiigtonia Sonorae. is found in the mountain canons of western Sonora and southern Lower California and as yet is quite imperfecth' known. 62 II()i(,n's Amkrican "Woods. 200. WASHINGTONIA FILAMENTOSA. <>. K. Califokma Fan Pai.m, I)i;si;kt Pai.m. Ger. , Callfor/if'sr/ie Wi'ilAjMiliiK' • Fr., Ptilmn Pdhtia (le (ihanico. Specific Characters: — Leaves light green, 5 to 6 ft. in length and nearly as broad, with stout elongated petioles 4-6 feet long and about 2 in. bioad at tlie ujtper end, 5 or 6 in. at base, where they split and widen into the slieathing base, and strongly armed along the margins with variously curved and straiglit tliin broad-based spines; ligulas 4-G in. long irrejrularly lariniate. Floicers (May to June) slightly fragrant, in glabrous light-green paniculate spadices. 10 to 12 feet long, from tlie axils of upper leaves, at first erect and spreading, but finally pendulous. Fruit (ripe in September) very abundant black drupes, about I in. long with thin sweet pulp; seed i in. long. flie specific name, iila>iientosa, is from the hfitin filum, thread, refeiYing to the tliread-Uke fibres hanging from the edges of the leaves. This beautiful Palm, the lari^est of the family ^rowin^ within the United States, sometimes attains the lieiglit of 75 ft. (22 m.j, with a trunk o ft. ( I m.)(»i' somewhat more in diameter at liase. It !.- crowned with a tuft of i>;reat fan-s'haped liejht «rreen leaves, which, sprinii'ino; vertically from the f»:rowing summit, }j;radually hend <>nl- ward, and when finally brown and lifeless lop down about the trunk where a great mass of them accumulates and persists for some years until they gradually drop away and leave the naked brown columnar trunk rough with the projecting wire-like bundles of wood. This is the appearance of the tree unkempt, in its desert home, but with ornamental trees the old leaves are usually trimmed off as soon as they l)econie unsightly and droop. The trunk is then left, either wickered over, as it were, with the forked l»ases of the old leaves or those too are trimmed away and an annulated rind-like covering remains, riAiJiTAT. — Along the borders of the depression in the Colorado Desert, which was once filled l>y an inland sea, extending uj) some ot tlie canons <.'f the neighlioring San ,Iacinto and San Bernardino ]\Iountains and ranging southward into Lower California, growing in moist and usually alkaline soil near the beds of canons and water courses where it forms in jilaces small open groves. Physical Propehtiks. — The wood of this Palm is liglit and .«>ft, with rather large fibro- vascular bundles of a garnet color in old trunks, and sparsely distributed through the mass of pinkish colored pith like intervening tissue (parenchyma), each bundle with two or three large ducts near the periphery. The color above alluded to is wliat I have seen in old wood taken from near the base of the trunks "Washixgtoxia filamkntosa — Camfoknia Fan Paf.m. 63 wliose exterior was charred by repeated burnings of the accumulated (lead leaves about their crowns by the Indians, and I am inclined to think that the tissues of the trunk were colored in consecjuence. In new wood the parenchyma is nearly white, and the bundles of a light greenish yellow color. The wood shrinks very greatl}' in drying, the area covered by one of our transverse sections being now only about half what it was when the tree was freshly cut. As the shrinkage is mainly in the paren- chymatous tissue the bundles of wood must not be considered as being as close together in the growing tree as shown in the accom])anying section. UsKs. — The fruit of this tree has long been an article of food by the Indians, who eat it fresh and also grind the seeds into a flour. They have a habit of setting lire to the dead leaves which accumulate about the crown of the tree and which they are said to do for a double purpose — offering incense to the souls of theii- departed ancestors and hastening the ripening of the fruit, which I am told they can do l)y about a month. The Washington Palm is justly very popular for ornamental plant- ing, and so extensively has it been planted along the streets and about the orange orchards of southern California that it has become a feature already prominent in the aspect of the region, and in time will giv3 it the appearance in places, it would seem, almost of palm forests.
