. Trees and shrubs : an abridgment of the Arboretum et fruticetum britannicum : containing the hardy trees and schrubs of Britain, native and foreign, scientifically and popularly described : with their propagation, culture and uses and engravings of nearly all the species. Trees; Shrubs; Forests and forestry. / + 1991. T. occident41Is. which is surmounted by a short wing. Compared with the Oriental, or Chinese, arbor vitae, the American species is a loose irregular-headed tree, with the branches much more horizontal than in that species. The rate of growth, in the climate of London, is from 6 in. to 1 ft. in a year. In ten years, in fa- vourable soils, it will attain the height of 10 or 12 feet; and in 30 or 40 years, in moist sheltered situations, drawn up by other trees, it will attain the height of 30 or 40 feet. The most common use of this tree in America is for rural fences, for which it is highly esteemed. The posts last 35 or 40 years, and the rails 60 years ; or three or four times as long as those of any other species. The posts remain undecayed twice as long in argillaceous as in sandy soils. In Britain, the American arbor vitae can only be considered as an ornamental shrub or low tree ; thriving well in any soil, even in the most exposed situa- tions, but attaining its largest size in low, sheltered, and moist places. It grows much faster than the oriental arbor vitse, bears the knife and the shears, and is frequently employed to form hedges for shelter in gardens and nursery grounds. Readily propagated by seeds, which are procured in abundance from America or gathered from British trees, or by cuttings. i. it 2. T. (o.) plica'ta Donn. The plicate, or Nee's, Arbor Vitae.
