By taking the ether the other day I was convinced how far asunder a man could be separated from his senses. You are told that it will make you unconscious, but no one can imagine what it is to be unconscious—how far removed from the state of consciousness and all that we call “this world”—until he has experienced it. The value of the experiment is that it does give you experience of an interval as between one life and another,—a greater space than you ever travelled. You are a sane mind without organs,—groping for organs,—which if it did not soon recover its old senses would get new ones. You expand like a seed in the ground. You exist in your roots, like a tree in the winter. If you have an inclination to travel, take the ether; you go beyond the furthest star. It is not necessary for them to take ether, who in their sane and waking hours are ever translated by a thought; nor for them to see with their hindheads, who sometimes see from their foreheads; nor listen to the spiritual knockings, who attend to the intimations of reason and conscience. _May 16._ Heard the whip-poor-will this evening. A splendid full moon to-night. Walked from 6.30 to 10 P. M. Lay on a rock near a meadow, which had absorbed and retained much heat, so that I could warm my back on it, it being a cold night. I found that the side of the sand-hill was cold on the surface, but warm two or three inches beneath.[167] If there is a more splendid moonlight than usual, only the belated traveller observes it. When I am outside, on the outskirts of the town, enjoying the still majesty of the moon, I am wont to think that all men are aware of this miracle, that they too are silently worshipping this manifestation of divinity elsewhere. But when I go into the house I am undeceived; they are absorbed in checkers or chess or novel, though they may have been advertised of the brightness through the shutters. In the moonlight night what intervals are created! The rising moon is related to the near pine tree which rises above the forest, and we get a juster notion of distance. The moon is only somewhat further off and on one side. There may be only three objects,—myself, a pine tree, and the moon, nearly equidistant. Talk of demonstrating the rotation of the earth on its axis,—see the moon rise, or the sun! The moonlight reveals the beauty of trees. By day it is so light and in this climate so _cold_ commonly, that we do not perceive their shade. We do not know when we are beneath them. * * * * * According to Michaux, the canoe birch (_Betula papyracea_) ceases below the forty-third degree of latitude. Sections of the wood from just below the first ramification are used to inlay mahogany, in these parts. It is brought from Maine for fuel. Common white birch (_B. populifolia_) not found south of Virginia. Its epidermis incapable of being divided like the canoe birch and the European white. The common alder (_Alnus serrulata_) blooms in January.
