THE NORTHERN CYPRESS.
The Northern Cypress, or White Cedar, is a more stately tree than the juniper, but it is never seen by our waysides; it will thrive only in swampy soils. This is the tree that covers those extensive morasses known as cedar swamps, which are, perhaps, the best examples extant of the primitive forest. The White Cedar is not often called the Cypress in New England, and in general appearance, and especially in the style of its foliage, bears but little resemblance to the Southern Cypress; but its similarity to the juniper is very striking. It is a taller tree than the European Cypress. By some botanists it is classed with the arbor-vitæ.
This tree is not confined to inland moors, but is often found upon marshes which are overflowed by the tide of the ocean. Cedar swamps are common in all the maritime parts of the country. In many of them in New England the trees are so closely set that it is difficult to traverse them. Their wetness presents another obstacle to the traveller, except in winter, when the water is frozen, or in the driest part of summer. In these swamps there is a covering, in some parts, of bog-moss, from six inches to a foot deep, always charged with moisture, in which are embedded several half-parasitic plants, such as the white orchis. The White Cedar constitutes with the southern cypress the principal timber of the Great Dismal Swamp, and is the last tree, except the red maple, which is discovered when travelling through an extensive morass.
Michaux remarks that in the Southern swamps which are occupied by the Northern and Southern Cypress, the former “are observed to choose the centre of the swamps, and the southern cypresses the circumference.” In the region of the southern cypress the cedar swamps are skirted by the tupelo and the red maple. There is but little superficial resemblance between the two cypresses. The foliage of the Northern tree is evergreen. “Each leaf,” says Michaux, “is a little branch numerously subdivided, and composed of small, acute, imbricated scales, on the back of which a minute gland is discovered with the lens. In the angle of these ramifications grow the flowers, which are scarcely visible, and which produce very small rugged cones of a greenish tint, that change to bluish towards the fall, when they open to release the fine seeds.”
