I am interested in each contemporary plant in my vicinity, and have attained to a certain acquaintance with the larger ones. They are cohabitants with me of this part of the planet, and they bear familiar names. Yet how essentially wild they are! as wild, really, as those strange fossil plants whose impressions I see on my coal. Yet I can imagine that some race gathered those too with as much admiration, and knew them as intimately as I do these, that even they served for a language of the sentiments. Stigmariae stood for a human sentiment in that race’s flower language. Chickweed, or a pine tree, is but little less wild. I assume to be acquainted with these, but what ages between me and the tree whose shade I enjoy! It is as if it stood substantially in a remote geographical period.
