LXXIV. CANADIAN TREES.

FIRST READING.—SOFT WOODS.

The principal evergreen, or cone-bearing trees, natives of Canada, are Pines, Firs, and Thujas.

As every one cannot distinguish a Pine from a Fir, this lesson is illustrated with drawings, showing the peculiar character of each, so that any boy or girl may be able, when looking at a cone-bearing tree, to decide whether it is a Pine or a Fir.

Fig. 1 represents a small piece of the twig of a White Pine. On examination it will be seen that the leaves are needle-shaped, and spring from the young shoot in little tufts of fives, all issuing from one point. This arrangement and form of the leaf are peculiar to Pines, and should be kept in mind when examining a tree, in order to know whether it is a Pine or a Fir. Every Pine tree, however, has not five leaves issuing from one point; some have only two, and there are others, again, that have three.

Fig. 2 represents a twig of the Hemlock Spruce Fir, a tree well-known to nearly every young person in Canada. Looking at this illustration, we at once observe that the leaves are distributed singly on the young shoot, and stand out in two rows. In the case of a few species of Fir, however, the leaves are not thus arranged, but are scattered all round the twigs, being stiff and pointed, as shown in Fig. 3, which represents a twig of the common Black Spruce Fir. In all cases, Firs have their leaves springing singly from the twigs, an arrangement by which any child can distinguish them from Pines.

Of all our native trees, Pines are considered the most valuable, as their timber can be used for almost every purpose for which wood is required, especially for house-building, ship-building, fencing, and railway construction. The two principal species are the White and the Red Pine.

The White Pine is one of the grandest trees of our Canadian forests. It grows to very large proportions on dry, gravelly lands, where it is not crowded by other trees. We often find individual pine trees rising to the height of 200 feet, with stems from four to six feet in diameter near the ground; but in general they may be said to reach 150 feet, with a diameter of about three feet. In the earlier settled parts of the country, the best and largest trees of this species were cut down long ago; but thousands of fine specimens are still to be met with in the backwoods.

The Red Pine does not grow to so large a size as the White, nor is it found so plentifully in our forests. It is to be met with only on dry, gravelly knolls, and in rocky parts of the country, generally in patches of small extent, and seldom among other trees. Its timber is of the best description, and is much sought after by lumbermen. Owing to this cause it is now comparatively scarce. All Pines are reared from seeds, which may be found ripe in their cones in the month of November.

Although our Fir trees are, generally speaking, not so important as our Pines, still, there are two or three of them well worthy of being brought under notice here, particularly the Douglas Fir, the Hemlock Spruce Fir, the common Black Spruce Fir, and the Balsam Fir.

The Douglas Fir is not found in the woods east of the Rocky Mountains, but it grows in the immense forests of British Columbia to heights varying from 150 to 250 feet, with trunks from three to ten feet in diameter. A peculiar feature of this Fir is, that the bark on old trees is found from ten to fourteen inches thick. Where full grown, this grand Fir usually stands apart from other trees, and forms a majestic object in the landscape, being clothed with horizontal branches from the base to the top. The timber is exceedingly durable, and in its native province is much used for general purposes. It is also exported for ship-masts, the tall, clean stems making the best of material for this purpose.

The Hemlock Spruce Fir, most young people of Canada are acquainted with, as it is widely distributed, and found in many bushes of the country. In open situations, and on cool-bottomed lands, the Hemlock is a noble tree; while young it is very graceful in form, and when approaching maturity its horizontal limbs give it the appearance of the Cedar of Lebanon. Its timber, however, is not esteemed so highly as that of the Pine, being of a loose and open character. But, although this is the case, it is largely used for rough boarding purposes, as in building barns, and in making side-walks. The bark of this tree is valuable for tanning leather.

The Black Spruce Fir, or Gum Spruce, as it is often called, is very common on most flat and cool-bottomed lands in Canada, and also on the banks of lakes and rivers. It is a tall and beautifully formed tree, having a dark brown bark, and very dark green leaves. It is from these characteristics that it derives its name. It grows to a height varying from 70 to 100 feet, but the stems seldom attain diameters over two feet at the bottom. The timber, though light, is very tough and strong.

The Balsam is one of the handsomest members of this family. Commercially it is not of much value, but as an ornamental tree it is unsurpassed—its regular conical form, closely set branches, and deep green leaves, rendering it a conspicuous object in any landscape. The Balsam seldom exceeds forty or fifty feet in height.

Although the Firs, like the Pines, are reared from seeds which ripen in October and November, they may be grown from cuttings of the young wood, as rare kinds sometimes are when their seeds cannot be had.

The Thuja, or Arbor vitÆ, as it is generally called, is a very useful class of Canadian trees. It grows to a large size, and is found chiefly on the Pacific slope. There is only one species which is a native of Ontario, and to it alone we shall here refer. It is known to most people in Ontario under the name of the White Cedar. How it came to be called a Cedar we do not know; but its true name is the Arbor vitÆ. This species is too familiar to the people of the eastern provinces of Canada to require any lengthened description, as many farmers have it growing in the swampy parts of their bushes, and find it useful for various purposes, especially as rails for fencing.

The leaves of this tree are so small, that to a casual observer, they scarcely appear to be leaves. If they are closely looked at, however, it will be seen that they are in opposite pairs, and lie flat and pressed on the twigs, each pair overlapping the other like the shingles on a house-top. When they are roughly handled, they give out a strong aromatic smell. The tree, although it grows to large dimensions—some times to eighty or ninety feet in height, with stems from two to three feet in diameter—cannot be considered an ornamental one, as its branches are too loose and open, and its leaves too small, to give it a clothed look. Its timber, however, is of the most valuable description, being very durable, and in this respect it is not surpassed by any other tree. Much of it is used for railway ties. The Thujas are all grown from seeds, but like the Firs, they may be reared from cuttings.
