But, after all, man is the great agent in promoting vegetable migration. It is by his agency that the most precious seeds are borne across the wide ocean. He carries them in all his wanderings among his richest treasures; while others follow his course, whether he will or not, mingling with his rarer seeds, or adhering unseen to his household stuff. The animal fleabane (Erigeron Canadense) was sent from Canada to France, in bales of fur, and from thence, by natural propagation, into all the countries of Europe. The tree primrose (Œnothera biennis), so common in our own vicinity, was first naturalized in the neighborhood of Liverpool, and from thence distributed by its own spontaneous effort all over the civilized world.

Our own vicinity is a remarkable exemplification of the fact. All around us we see trees, shrubs, and herbacious plants, that once were strangers to the soil. A change is still sweeping over the face of nature. The noble race of forest-trees, and the
