of long duration, it should never be placed where it is intended to act as a 
screen. Like all objects the chief beauty of which consists in their singularity, 
it produces the most striking effect when standing alone on a lawn. If trained 
to a single stem, either of the forms of this species may be made an interest- 
ing small tree, but not one of many years’ durability. Price, in the London 
nurseries, 1s. a plant, and seeds 1s. an ounce ; at Bollwyller, 50 cents a plant ; 
and in New York, 25 cents a plant, and seeds 1 dollar a quart.

figured in Dend, Brit., t. 16., has dicecious sexes, and red flowers. 
It is distinguished by a more upright habit of growth, and smoother 
branches and leaves, than &. glabra. The leaves are glaucous 
underneath ; and the fruit is of a rich velvety crimson. 
Description, §c. The general appearance of the species 
is similar to that of R. typhina; but the plant is smaller, 
the branches more spreading and smooth, and the leaf- 
lets wider, less serrated, and of a deeper green. There 
are many varieties of R. typhina in North America; 
and, to us, it appears highly probable that 2. glabra is 
only one of these. According to Kalm, the species or 
variety under notice is exceedingly common in woods 
throughout great part of North America, both in culti- 
vated and uncultivated districts. In woods, it is found 
on the margins of open glades; and, in cultivated parts 
of the country, it less common in low meadows than 
in corn fields, ‘‘ It is like a weed in some parts of the 
country ; and, if a field be left a few years uncultivated, ( 
this shrub overruns it, from berries whieh are brought , 
by birds; and, when the ground comes again into til- 
lage, the roots stop the plough very much. The fruit _ 
remains on the shrub during winter; but the leaves drop 
very early in autumn. It seldom grows above 9ft. high. The wood burns 
well, without much crackling. On cutting the stem, a yellow juice comes 
out between the bark and the wood; one or two of the outer circles of the 
wood are white, but the innermost are of a yellowish green; it contains a 
pith frequently half an inch in diameter, or more, of a brown colour, and so 
loose, that it is easily pushed out by a stick. The branches, boiled with the
