Seite 1 - THERE rolls the deep where grew the tree. O earth, what changes hast thou seen ! There where the long street roars, hath been The stillness of the central sea. The hills are shadows, and they flow From form to form, and nothing stands ; They melt like mist, the solid lands, Like clouds they shape themselves and go.
Seite 57 - ... water, and four or five feet higher up, is greatly enlarged by prodigious buttresses, or pilasters, which, in full grown trees, project out on every side, to such a distance, that several men might easily hide themselves in the hollows between. Each pilaster terminates under ground, in a very large, strong, serpentine root, which strikes off, and branches every way, just under the surface of the earth...
Seite 39 - Tree! a living thing Produced too slowly ever to decay; Of form and aspect too magnificent To be destroyed.
Seite 211 - I know, Some harshness show, All vain asperities I day by day Would wear away, Till the smooth temper of my age should be Like the high leaves upon the Holly Tree.
Seite 57 - ... on the ground as a dark intervening cloud, which from time to time excludes the rays of the sun. The delicacy of its color and the texture of its leaves exceed everything in vegetation.

No less than seventeen different forms have been described from the rocks of this age, and the localities where they have been found are scattered from Australia to Bohemia, Greenland, and Vancouver Island. A large...
Seite 57 - Cupressus disticha stands in the first order of North American trees. Its majestic stature is surprising; and on approaching it, we are struck with a kind of awe, at beholding the stateliness of the trunk, lifting its cumbrous top towards the skies, and casting a wide shade upon the ground, as a dark intervening cloud, which, for a time, excludes the rays of the sun.
Seite 257 - Between 90 and 100 fossil forms have been described. In that grand display of dicotyledonous genera which during the mid-Cretaceous replaced the old Mesozoic flora of ferns, cycads, and conifers and which appeared with such apparent suddenness at a number of points in the northern hemisphere, we find unmistakable evidence of the abundance and wide distribution of species of Diospyros. No less than seventeen different forms have been described from the rocks of this age, and the localities where they...
Seite 77 - ... plants are the remains of a species of walnut, a striking commentary on the changes which have since taken place. I have attempted to give a graphic summary of the present and past range of the walnuts on the accompanying sketch map (fig. 2), where the areas of distribution of the existing species (somewhat exaggerated) are shown in solid black. It is possible that the part of the range of Juglans regia in southern Asia should be extended eastward over Tibet, through northern China to Japan....
