object of beauty, is equalled by very few flowering shrubs, and 
far surpasses that produced by any other tree. 
In the forest, it rises with a uniform shaft sixty or eighty 
feet, with its diameter but slightly diminished until near the 
top, when it tapers very rapidly and forms a head round and 
full of branches. Below, it is set with stiff, broken, dead limbs, 
projecting at right angles to the trunk. The rapid tapering of 
the extremity of the stem, may be noticed at every period of its 
growth, and forms a striking peculiarity in the appearance of 
the tree. 
The trunk of the hemlock is covered with a reddish bark, 
somewhat roughened by long shallow furrows, when it is old, 
but less so than on many other trees. The branches and 
small twigs have a smooth, light gray bark. The branchlets 
are very small, light and slender, and are set irregularly on 
the horizontal sides of the small branches, forming with them 
a flat surface. This arrangement renders them singularly 
well adapted to the making of brooms, a use of the hemlock 
familiar to housewives in the country towns throughout New 
England. In the disposition of the limbs, there is no approach 
to the regular stages of whorls, characteristic of the other pincs, 
but they are scattered without order along the trunk, and being 
rather small, and horizontal, with an easy sweep upward, ren- 
der a hemlock of forty or fifty feet, which has stood alone, the 
most graceful of the evergreens. ‘The leaves are very small 
and flat, entire or with a few minute teeth towards the end, 
green above, and shining with rows of silvery dots beneath. 
They are on very small, thread-like footstalks, arranged in 
spirals around the branch, but disposing themselves, by the 
bending of the footstalks, in two rows on the sides. 
The sterile flowers are on small aments at or near the end of 
the smaller branches. Each ament has at its base a few mem- 
branaceous brown scales, and, at a little distance above them, 
an oblong head, one-tenth of an inch long, formed of from ten 
to twenty heart-shaped, hollow scales, beneath each of which 
are two cells full of the fertilizing dust. 
The fertile aments are on the ends of the outer branchlets, 
They are egg-shaped, one-fourth of an inch long, and imbri-
