This too well-known climbing shrub is gaining ground in certain sections of the country. Formerly it was unknown in New England, but now it infests many farms and roadsides there, as in New York and New Jersey. It flourishes in salt air and in every kind of soil. By means of tiny rootlets on its stem it climbs to the very tops of high trees, enveloping their trunks in a mass of hard-stemmed, 3-leaved foliage; or it covers fences, stopping at the posts for extra decorative effects. It carries itself flauntingly and gaudily, in fall faintly imitating the Virginia creeper, with sickly hues of red and yellow. When it cannot climb it masses itself on the ground. The juice of the plant is thick and yellowish,becoming black after being exposed to the air. It produces an exceedingly irritating eruption upon the skin of persons susceptible to the rhus poison, often dangerous and difficult to heal Even of persons who are "immune" to this poison, if the juice of the plant is brought in contact with the blood, abscesses and painful sores will almost certainly be produced. It should be rooted out with hoe and plow by every self-respecting land-owner. (See illustration, p. 386.)
