In some coal-districts fossil fruits, named cardiocarpum and trigonocarpum, have been found in great quantities, and these have now been decided by botanists to be the fruits of certain conifers, allied, not to those which bear hard cones, but to those which bear solitary fleshy fruits. Sir Charles Lyell referred them to a Chinese genus of the yew tribe called salisburia.

I do not aver that the railroad is devoid of a kind of poetry of its own, the same kind of sentiment, nearly, that resides about anvils and smelting-furnaces in the Hartz Mountains and in the great coal-districts: an infernal kind of sentiment, for the most part, being inseparable from burning fiery furnaces and grime; as in "Fridolin," and in the "Song of the Bell," and in the "Forging of the Anchor."
