The English Elm may be seen on Boston Common, and in front of old mansions in Medford and other ancient towns in Massachusetts. Very few trees of this species, however, have been planted since the Revolution. This royal Elm seems to have lost favor when republicanism took the place of monarchy. Yet in many points the English Elm is superior to the American species. It is not a drooping tree; it resembles the oak in its general form, but surpasses it in height. The trunk is not subdivided; throughout its entire length, the branches are attached to it by wide angles, sometimes spread out in an almost horizontal direction. Selby remarks, that, “in point of magnitude, grandeur of form, and majestic growth, the English Elm has few competitors in the British sylva.” In the form of the leaf and spray it closely resembles the American tree; but the leaf is of a brighter green, it comes out several days earlier in the spring, and continues green in the fall a week or ten days after the American elm has become entirely denuded. The same difference, in a less degree, has been observed in the leafing and falling of the leaf of all European trees, compared with their kindred species in the American forest.
THE CHERRY-TREE.
Among our fruit-trees the Cherry occupies the most conspicuous place, considered with reference either to shade or ornament, surpassing all the others in size and in comeliness of growth. All the species are handsome trees, and some of them are of great stature. They are natives of all countries in the northern temperate zone, but not of any region south of the equator. The three most remarkable species of the family are the common garden Cherry, or Mazard, which is believed to be a native of Asia; the Great Northern Cherry, or Gean, of Europe; and the Black Cherry of the United States.
THE BLACK CHERRY.
The Black Cherry, which is a tree of the first magnitude in favorable regions, is only a middle-sized tree in the New England States. In the South and West, especially on the banks of the Ohio River, it attains a very great size, rising sometimes to one hundred feet, according to Michaux, with a corresponding diameter. It is sensitive to the extremes both of cold and heat, and to an excess either of dryness or moisture. In Maine it is only a small tree, being checked in its growth by the severe Northern winters. Very far south it suffers from the hot and dry summers, but prospers well in the mountainous parts. It forms immense forests in many districts of North America, in company with the honey locust, the black walnut, the red elm, and the oak. It is sufficiently common in New England to constitute an important ingredient of our wood scenery, and though indigenous, it is most abundant in lands which have been modified by cultivation.
This tree differs very obviously in its ramification from the garden cherry, in which the branches are always subordinate to the trunk, and arranged in irregular whorls and stages, one above another, so that, if they were horizontal, they would resemble those of a fir-tree. The Black Cherry tree, on the contrary, is subdivided in such a manner that the main stem cannot easily be traced above the lower junction of the branches, except in those which have grown in a forest. The branches are spread out more loosely, without the least of any arrangement in whorls, and their terminations are longer and smaller. The leaves of the two trees are also widely different: those of the garden cherry are broad, ovate, rough, and serrate; those of the American tree are lanceolate and smooth, and almost as slender as the leaves of the willow. The one bears its flowers and fruit in racemes, the other in round clusters or umbels. The trunk and bark of the two species are similar, both resembling the black birch in the properties of their wood and the outside appearance of their bark. The branches of the Wild Cherry are too straggling and sparse to make a beautiful tree, and the leaves being small and narrow, the whole mass is wanting in depth of shade.
THE CHOKE CHERRY.
When we are rambling in rustic lanes, that lead through rudely cultivated grounds, we frequently meet with groups of tall handsome shrubs, covered in May with a profusion of white flowers, and in August heavily laden with bright scarlet fruit. Such is the Choke Cherry, a small tree with which all are familiar from their frequent disappointment on attempting to eat its fruit. Its promises to the sight are not fulfilled to the taste. Though of an agreeable flavor, it is exceedingly harsh and astringent. This is a more beautiful tree when in flower than the black cherry, though it is generally a mere shrub, never rising above fifteen or twenty feet in height. The racemes, when in flower, are not drooping, as they are when laden with fruit, but stand out at right angles with the branch, completely surrounding it, and giving to every slender twig the appearance of a long white plume. In the eastern part of Massachusetts I have found this species, as well as the black cherry, in old graveyards,—so frequently, indeed, that in my early days these trees were associated with graves, as the Lombardy poplar is with ancient avenues. I suppose their frequency in these places to be caused by the birds dropping the seeds at the foot of the gravestones, where they quickly germinate, and are protected, when growing, by the stone beside them.
The cultivation of the Gean, or Great Northern Cherry of Europe, which was named by Linnæus the bird cherry, is encouraged in Great Britain and on the Continent of Europe for the benefit of the birds, which are regarded as the most important checks to the over-multiplication of insects. The fact, not yet understood in America, that the birds which are the most mischievous as consumers of fruit are the most useful as destroyers of insects, is well known by all the farmers in Europe; and while we destroy the birds to save the fruit, and sometimes cut down the fruit-trees to starve the birds, the Europeans more wisely plant them for their sustenance and accommodation.
