I might here quote the following, with the last—of roots: “They may even strike in the open air and light, as is seen in the copious aërial rootlets by which the Ivy, the Poison Ivy, and the Trumpet Creeper climb and adhere to the trunks of trees or other bodies; and also in Epiphytes or Air-plants, of most warm regions, which have no connection whatever with the soil, but germinate and grow high in air on the trunks or branches of trees, etc.; as well as in some terrestrial plants, such as the Banian and Mangrove, that send off aërial roots from their trunks or branches, which finally reach the ground.” So, if our light-and-air-seeking tendencies extend too widely for our original root or stem, we must send downward new roots to ally us to the earth. Also there are parasitic plants which have their roots in the branches or roots of other trees, as the mistletoe, the beech-drops, etc. There are minds which so have their roots in other minds as in the womb of nature,—if, indeed, most are not such?! _May 21. Wednesday._ Yesterday I made out the black and the white ashes. A double male white ash in Miles’s Swamp, and two black ashes with sessile leaflets. A female white ash near railroad, in Stow’s land. The white ashes by Mr. Pritchard’s have no blossoms, at least as yet. If I am right, the _black_ ash is improperly so called, from the color of its bark being lighter than the white. Though it answers to the description in other respects, even to the elder-like odor of the leaves, I should like still to see a description of the yellow ash which grows in made [_sic_]. The day before yesterday I found the male sassafras in abundance but no female. The leaves of my new pine on Merriam’s or Pine Hill are of intermediate length between those of the yellow pine and the Norway pine. I can find no cone to distinguish the tree by; but, as the leaves are _semicylindrical_ and not _hollowed_ I think it must be the red or Norway Pine, though it does not look very red, and is _spruce_! answering perhaps to the description of the yellow pine, which is sometimes called spruce pine. To-day examined the flowers of the _Nemopanthes Canadensis_,—a genus of a single species, says Emerson. It bears the beautiful crimson velvety berry of the swamps, and is what I have heard called the cornel. Common name wild holly. * * * * * I have heard now within a few days that peculiar dreaming sound of the frogs[170] which belongs to the summer,—their midsummer night’s dream. Only that thought and that expression are good which are musical.
