"The noblest and most beautiful English Elms in this country are found in Roxbury, the largest of which measures fifteen feet five inches five feet from the ground; it holds its size fully to the height of twenty or twenty-five feet, where it divides into three large branches, the main central one of which rises upward to a height much above one hundred feet." "As among the ancient Romans, so in France at the present day, the leaves and shoots are used to feed cattle. In Russia, the leaves of a species of the Elm are used as a substitute for tea. The inner bark is in some places made into mats, and in Norway they kiln-dry it, and grind it with corn as an ingredient in bread." THE BIRCH. Of the Birch family there are several varieties, called the Black, Yellow, Red, Canoe, the Gray, and the Dwarf. Of these the Yellow and Canoe Birches are the most interesting and useful. The general outlines of the Yellow Birch often resemble the Elm, the root-spurs rise high up the trunk, protruding much beyond the regular circle of its shaft. It is very firmly rooted, capable of withstanding a violent blast. It attains to the height of seventy or eighty feet, and often measures from nine to ten feet in circumference three and four feet from the ground. Its wood is very useful for cabinet purposes, and is excellent for fuel. The White or Canoe Birch is most remarkable for the beautiful thin sheets of bark which it affords, from which the Indian canoe is constructed. It also makes excellent covering for a tent. In some parts of the northern regions it is said to attain a diameter of six or seven feet. The White Birch possesses "in an eminent degree the lightness and airiness of the Birch family, spreading out its glistening leaves on the ends of a very slender and often pencil spray, with an indescribable softness. So that Coleridge might have called it as he did the corresponding European species, "Most beautiful Of forest trees--the lady of the woods." THE MAPLE-TREE.
