The Douglas Fir is of pyramidal outline, with the lowest branches

bending to the ground under their weight of branchlets and leaves;

above, they spread horizontally, but the uppermost are more or less

ascending. The branchlets are given off mostly in opposite pairs,

densely clothed with slender, rich green leaves, 3/4 to 1-1/4 inches in

length, paler beneath. They endure for six or seven years, and are

arranged in three or four ranks. The male flowers will be found

clustered at intervals on the underside of the previous year's shoots,

whilst the cones are formed at the tips of the lateral branchlets, and

hang downwards. These cones are somewhat elliptical in outline, from

2-1/2 to 4 inches long, with large scales, and from the back of each

there extends a three-clawed bract, whereof the middle claw or awn is

very long. Several well-marked varieties of the Douglas Fir are also to

be met with occasionally in parks and gardens.

The Douglas Fir produces excellent timber, and is a most valuable forest

tree, not only on that account, but because of its adaptability to

varying conditions of soil and climate. It is the most widely

distributed of all American forest trees, and the area of its

distribution is spread over thirty-two degrees of latitude, and from end

to end of this range it has, in the words of Sargent, "to endure the

fierce gales and long winters of the north, and the nearly perpetual

sunshine of the Mexican Cordilleras; to thrive in the rain and fog which

sweep almost continuously along the Pacific coast range, and on the arid

mountain slopes of the interior, where for months every year rain never

falls." It appears to thrive best where the air is humid and the soil

well drained. It begins to bear cones about its twenty-fifth year. The

straight tapering trunk is largely used for the masts and spars of

ships, its suitability for this purpose being evident to all visitors to

Kew who have gazed at the flag-staff set up in the arboretum. This pole

is 159 feet long, with a circumference of 6 feet at the base, tapering

to 2 feet 2 inches at the top, and weighing about 3 tons. It was brought

from Vancouver Island, and an examination of its rings before it was set

up showed that it represented the growth of about 250 years. The full

life of the Douglas Fir is estimated to be about 750 years.

[Illustration: _Pl. 165._ Bole of Stone Pine.]

The Stone Pine (_Pinus pinea_).

Between the tall, graceful spire of the Douglas Fir and the squat,

heavy, umbrella-like head of the Stone Pine, there is an enormous

contrast. It must be confessed that the Stone Pine is less beautiful

than picturesque, a point that strongly commends it to the landscape

painter working in the countries bordering the Mediterranean, in

which region it is native. The date of its introduction to Britain is

not known, but it has been in cultivation here certainly for more than

three centuries and a half, for Turner mentions it in his "Names of

Herbes in Greke, Latin, Englishe, Duch, and Frenche," published in 1548.

In its native countries it attains a height of sixty to eighty feet, but

in this country the finest examples are only about thirty-five feet,

whilst ordinary British-grown examples are only half that height. Its

trunk, covered with rugged, and deeply fissured, thick, red-grey bark,

forks at no great distance from the roots, and sends off massive

spreading branches of great length. For several years the young tree

produces short single leaves, but later leaves are five or six inches

long, slender, and of a bright green tint, in pairs, united at their

base by a pale sheath. These leaves endure for two or three years. The

pollen-bearing flowers are crowded into a spike. The female flowers are

about three-quarters of an inch long, composed of pale greenish scales.

After fertilization, these grow to a length of four to six inches, of a

rugged oval form and red-brown colour, ripening in the third year. The

scales of these cones are somewhat wedge-shaped, with a stout rhomboid

boss, which has a depression round the central protuberance. The seeds,

which are eaten for dessert and preserved as sweetmeats in the countries

where the Stone Pine is native, are enclosed in a bony shell, and it is

from this circumstance that the tree gets its name.

[Illustration: _Pl. 166._ Austrian Pine.]

[Illustration: _Pl. 167._ Bole of Austrian Pine.]

The Austrian Pine (_Pinus laricio_).

What is known as the Austrian Pine is a variety of the Corsican or Larch

Pine, and its botanical name correctly set out is _Pinus laricio_, var.

_austriaca_. The name has reference to the fact that its chief home as

an indigenous tree is in the southern provinces of the Austrian Empire.

The range of the type and its varieties together includes Central and

Southern Europe, and part of Western Asia. It is a comparatively recent

addition to our sylva in both forms, for the type was introduced in

1759, in the belief that it was a maritime form of the Scots Pine, but

the variety _austriaca_ was first sent out by Lawson and Son, the

Edinburgh nurserymen, in 1835.

[Illustration: Austrian Pine.]

The typical species (Corsican Pine) is a slender tree of somewhat

pyramidal form, growing to the height of 80 to 120 feet. The Austrian

Pine, though a large tree, is of smaller proportions--from 60 to 80 feet

high--but with stouter and longer branches, and denser foliage. The

leaves, which vary from three to five inches in length, are sheathed in

pairs, convex on the outer side, rigid, glossy, dark green, and with

toothed margins. The cone is conical (!), with a rounded base, two to

three inches in length, and its position on the branch is almost

horizontal, the scales somewhat similar to those of the Scots Pine, but

with stronger bosses, and of a yellowish-brown colour, polished. It

takes about seventeen months to become full grown and ripen the seeds.

[Illustration: _Pl. 168._ Cones of Austrian Pine.]

The Austrian Pine is one of those that do well on poor soils, and takes

kindly to chalk. From the density of its foliage, it makes a good shade

and shelter tree. Its timber, though coarse in grain, is very durable,

and useful for outside work.

[Illustration: _Pl. 169._ Cedar of Lebanon.]

Cedar of Lebanon (_Cedrus libani_).

Made familiar, by name at least, from very early times by frequent

references to it in the books of the Old Testament, it is rather strange

that so hardy a tree was not one of the first of those introduced for

ornament into Britain. It is true that local legends attaching to some

old Cedars in this country credit them with having been planted in "the

spacious times of great Elizabeth"--as the great Cedar at Whitton,

Middlesex, blown down in 1779; but, on the other hand, we have the fact

that no mention is made of the Cedar by John Evelyn in his "Sylva"

(1664). This, it is true, is only negative evidence; but it is strong

none the less, for it is not at all likely that so keen and pious an

arboriculturist would have omitted mention of so noteworthy a tree had

such been growing here when he wrote. There is reason to believe,

however, that the still-existing Enfield Cedar was planted about the

date of Evelyn's publication by Dr. Uvedale, master of the Enfield

Grammar School.

The researches of Sir J. D. Hooker, subsequent to his memorable

expedition to Lebanon and Taurus in 1860, established the specific

identity of the three Cedars known as the Mount Atlas Cedar, the Cedar

of Lebanon, and the Deodar. Though the arboriculturist still treats them

as distinct species, they are scientifically regarded as geographical

forms of one species. For convenience we here adopt the

arboriculturist's view.

[Illustration: _Pl. 170._ Bole of Cedar of Lebanon.]

[Illustration: Cedar of Lebanon.]

The Cedar varies greatly--no tree more so--in height and general

outline, according to situation and environment, and though the stature

of well-grown trees in this country may be correctly stated as from 50

to 80 feet, we are not without examples of 100 and 120 feet where the

conditions have been specially favourable. There is one of 120 feet at

Strathfieldsaye, and among the numerous fine Cedars at Goodwood there is

the celebrated Great Cedar, 90 feet high, with a bole 25 feet in

circumference, and a broad conical head whose base has a diameter of 130

feet. But the Cedar, as usually seen on lawns and in parks, has a low,

rounded, or flattened top, the great spreading arms having grown more

rapidly than the trunk. Thus grown, the huge bole has seldom any great

length, throwing out these timber branches at from six to ten feet from

the ground, and immediately afterwards the trunk is divided into several

stems. From these the main branches take a curving direction, at first

ascending, but the part furthest from the trunk becoming almost

horizontal. It is chiefly at the extremity of the branches that the

branchlets and leaves are produced.

The evergreen leaves last for three, four, or five years, and are of

needle-shape, varying in length from a little less to a little more than

an inch. They are produced in a similar manner to those of the Larch--in

tufts that are arranged spirally round dwarf shoots, mostly on the upper

side of the branchlets. The male flowers are to be found at the

extremity of branchlets which, though six or seven years old, are very

short, their development having been arrested. The solid, purple-brown

cones are only three or four inches long, broad-topped, and with a

diameter of about half the length; the scales thin and closely pressed

together; they are at first greyish-green, tinged with pink. The

development and maturity of these cones takes two or three seasons, and

they remain on the tree for several years longer. The seeds are angular,

with a wedge-shaped wing.

The trees do not produce cones until they are from twenty-five to thirty

years old; but they may be a century old before producing either male or

female flowers.

The trunk is covered with thick, rough, deeply fissured bark. On the

branches the bark is smooth, and peels off in thin flakes. The Cedar, in

its native habitat, produces admirable timber, but that of trees grown

in our own country is described by Loudon as "reddish-white, light and

spongy, easily worked, but very apt to shrink and warp, and by no means

durable." For these reasons the tree is grown almost solely for

ornament.

The name Cedar is supposed to be derived from the Arabic _kedroum_, or

_k[e']dre_ (power), and has reference to its majestic proportions and

strong timber.

* * * * *

[Illustration: _Pl. 171._ Deodar.]

The Deodar, or Indian Cedar (_Cedrus deodara_).

Although, as we have indicated, the differences between the Cedar of

Lebanon and the Cedar of Himalaya are not such as can be scientifically

accepted as constituting specific distinctness, they are sufficient to

at once strike the ordinary observer. In proportion to the height of the

trunk, for example, the main branches are much shorter, the result being

a more regular pyramidal outline, terminating in a light spire. The

terminal shoots of the branches are longer, more slender, and quite

pendulous. These differences, though really slight, transform the rather

heavy majesty of the Cedar, as represented by _C. libani_, into one of

graceful beauty. Although the experience of sixty years has sadly

falsified the high hopes entertained as to the suitability of the Deodar

for cultivation in this country as a timber tree, its value for

ornamental purposes and in landscape gardening has not been impaired.

The headquarters of the Deodar are in the mountains of north-west India,

where it forms forests at various altitudes above 3500 feet. Its

vertical distribution, indeed, extends to a height of 12,000 feet, but

its principal habitat lies between 6000 and 10,000 feet. Deodar timber

produced in its native forests is exceedingly durable, being compact and

even grained, not liable to warp or split, and standing the test of

being alternately wet and dry. Loudon states that when a building, which

had been erected by the Emperor Akbar in the latter part of the

sixteenth century, was pulled down between 1820 and 1825, the Deodar

timber used in its construction was found to be so sound that it was

again used in building a house for Rajah Shah. And Brandis tells of very

much more ancient bridges in Srunagar, whose piers are of Deodar wood,

and appear to be as yet unaffected by decay.

[Illustration: Deodar. A, cone.]

It is to the Hon. W. L. Melville that we are indebted for the

introduction of the Deodar to Britain in 1831, and during the next ten

years many young trees were raised here from seeds. Favourably impressed

by the rapidity of growth of these seedlings, the government, fearing a

coming shortage of Oak for naval purposes, imported and distributed

large numbers of Deodar seeds, and high estimates were formed of the

future value of these trees. But in framing these estimates one

important factor was omitted--the uncertainty of the British climate,

with its rapid changes, "everything by turns, and nothing long." A score

or two of years served to demonstrate that such conditions were opposed

to the longevity and uniform development that produced sound timber on

the Indian mountains; and to-day the Deodar is not mentioned among the

trees that are to bring riches to the British timber grower. In spite

of this failure, there are to be seen in many parts of these islands

fine young Deodars of forty or fifty years, and from fifty to seventy

feet in height.

[Illustration: _Pl. 172._ Bole of Deodar.]

There is no necessity for repeating the particulars already given

respecting the Cedar of Lebanon, and which apply to the Deodar with such

modifications as are indicated in the first paragraph above. Specimens

grown where they have sufficient space for spreading out their long

arms, retain their branches to the base of the trunk, and if these are

cut off they can reproduce them. Several nursery varieties--with golden

(_aurea_), silvery (_argentea_), or more intense green (_viridis_)

foliage than the type--have appeared as a result of European

cultivation.

* * * * *

[Illustration: _Pl. 173._ Lawson's Cypress.]

Lawson's Cypress (_Cupressus lawsoniana_).

Lawson's Cypress belongs to that section of Conifers which includes the

Junipers and Thuias, and is a representative of the North American

Sylva. It is a native of South Oregon and North California, where it is

believed to have been first discovered by Jeffrey, about 1852. Two years

later seeds were received by Messrs. Lawson, the Edinburgh nurserymen,

from Mr. William Murray, and from these seeds were raised the first

young trees of this species sent out by the firm. The name was bestowed

in honour of Mr. Charles Lawson, the then head of the firm, and by this

name it is generally known in Europe, but in the United States it is the

Port Orford Cypress. At Port Orford, on the Oregon coast, according to

Sargent, "it forms one of the most prolific and beautiful coniferous

forests of the continent, unsurpassed in the variety and luxuriance of

its undergrowth of Rhododendrons, Vacciniums, Raspberries, Buckthorns,

and Ferns," and any one who has seen well-grown specimens in the

pleasure-grounds of this country can easily realize something of the

beauty of such a forest, though allowance has to be made for the fact

that in forest growth the lower branches are lost at an early age.

[Illustration: Lawson Cypress.]

In its native home the Lawson Cypress attains a height of between 120

and 150 feet, occasionally reaching 200 feet, with a base circumference

of 40 feet. The thick brown bark splits into rounded scaly ridges. The

short horizontal branches divide a good deal towards their leafy

extremities, which are curved, and commonly drooping. The leaves are

little evergreen scales, which overlap, and being closely pressed to the

branchlet, completely clothe and hide it. They are bright dark-green in

colour, and endure for three or four years. The male flowers are

produced at the tips of short branchlets, formed a year earlier. They

are of cylindric form, crimson in colour, and each stamen bears from two

to six anther-cells. The small "cones" are more or less globular, but

instead of a large number of spirally arranged overlapping scales, as in

the Pines and Firs, here there are only eight, whose edges at first join

to form a box. When the "cone" is ripe these scales separate, to allow

the escape of the seeds.

The Lawson Cypress produces a valuable wood, close-grained and strong,

yet light. It is considered one of the most important timber trees of

North America; but in this country it has been planted solely with a

view to its ornamental qualities. Its perfect hardiness and its freedom

of growth may, with longer experience than half a century affords, lead

to its being regarded as a timber producer here also.

The Common Cypress (_Cupressus sempervirens_) of the Mediterranean

region and the East, of which poets have sung in all ages, has been

cultivated in this country for at least three hundred and fifty years.

[Illustration: _Pl. 174._ Bole of Lawson's Cypress.]

The Chili Pine (_Araucaria imbricata_).

The Chili Pine, or "Monkey Puzzle," is a familiar sight on suburban

lawns, where, however, it seldom attains a large size or long retains

health. The lower branches drop off, and the upper ones become brown, as

though scorched. But away from the smoke-laden atmosphere and

uncongenial soils, some handsome and massive Araucarias may be seen

rising from fair lawns, with dense branches curving at their tips, and

regularly disposed in whorls from the dome-like head of the tree to the

grass at its base. Such was the magnificent specimen at Dropmore that

died in 1902, such is the fine tree at Woodstock, Co. Kilkenny, which

now presumably takes the position of eminence in these islands hitherto

held by the Dropmore example.

[Illustration: Chili Pine, and cone. A, seed, with attached wing.]

The Chili Pine is a native of Southern Chili, where it was discovered by

a Spaniard, Don F. Dendariarena, in 1780, as he was prospecting for

timber. About the same time two other Spaniards, Drs. Ruiz and Pavon,

were botanizing in Chili, and came across the Araucaria, of which they

sent herbarium specimens to Europe. But in spite of this three-fold

opportunity for Spain, the actual introduction of the Araucaria to

Europe must be credited to Britain. Archibald Menzies, who accompanied

Captain Vancouver as botanist on his celebrated voyage, came across the

tree in Chili, and brought home both seeds and young plants. One of

these became a fine tree at Kew, where it was for many years the object

of admiration and interest, but it perished in 1892.

[Illustration: _Pl. 175._ Chili Pine.]

The Araucaria forms extensive pure forests in the province of Arauco,

from which it gets its name, and to whose inhabitants the seeds are a

most important item of their food-supply. Not only do the trees in these

forests lose their lower branches, but even those growing in the open

plains of their native country have similarly bare trunks for nearly

half their height. It is therefore a satisfaction to know that the

finest specimens grown in this country have really surpassed those grown

in their natural home. The height reached by old trees is from eighty to

a hundred feet, with a trunk-girth of from sixteen to twenty-three feet.

The tapering of this trunk is very slight, and a few of the stiff,

spine-tipped leaves, with which its younger extremity is densely

clothed, still remain attached in a dried-up condition far down the

column. These leaves will have been observed to entirely cover the

branches, not being restricted, as in most trees, to the newly formed

branchlets and twigs. They are very hard, and endure for about fifteen

years; are about an inch and a quarter long, and overlap, though their

sharp-pointed ends turn away from the branch.

The cylindrical male flowers are four or five inches long, borne singly

or in small clusters. It was formerly supposed that the sexes were on

separate trees, but though many individuals only produce flowers of one

kind, this is by no means the general rule. The female flowers are about

four inches long, almost round in shape, but broader at the base than

above. They are covered with long, narrow, overlapping scales, beneath

which are found the seeds when the flower has developed into the brown

cone, which is six inches in diameter. The scales are then easily

detached; in fact, when the seeds are ripe, the cone falls to pieces.

The seed is about an inch and a half long, enclosed in a hard, thin

shell.

The Chili Pine does not succeed in this country unless it is given pure

air, sunshine, abundant moisture, and an open subsoil to carry it off.

Yet it will grow to a very handsome tree if these conditions are

observed. Very fine effects have been obtained in some places by

planting an Araucaria grove. Such an avenue is in fine condition at

Woodstock, Co. Kilkenny (running parallel with an avenue of _Abies

nobilis_), every tree with its branches intact from turf to summit, and

bearing fertile cones. There is a similar, but less perfectly preserved,

Araucaria grove at Bicton in Devonshire.
