_Nov. 23._ To-day it has been finger-cold.[94] Unexpectedly I found ice by the side of the brooks this afternoon nearly an inch thick. Prudent people get in their barrels of apples to-day.[95] The difference of the temperature of various localities is greater than is supposed. If I was surprised to find ice on the sides of the brooks, I was much more surprised to find quite a pond in the woods, containing an acre or more, quite frozen over so that I walked across it. It was in a cold corner, where a pine wood excluded the sun. In the larger ponds and the river, of course, there is no ice yet. It is a shallow, weedy pond. I lay down on the ice and looked through at the bottom. The plants appeared to grow more uprightly than on the dry land, being sustained and protected by the water. Caddis-worms were everywhere crawling about in their handsome quiver-like sheaths or cases. The wild apples, though they are more mellow and edible, have for some time lost their beauty, as well as the leaves, and now too they are beginning to freeze. The apple season is well-nigh over. Such, however, as are frozen while sound are not unpleasant to eat when the spring sun thaws them.[96] I find it to be the height of wisdom not to endeavor to oversee myself and live a life of prudence and common sense, but to see over and above myself, entertain sublime conjectures, to make myself the thoroughfare of thrilling thoughts, live all that can be lived. The man who is dissatisfied with himself, what can he not do? _Nov. 24._ Plucked a buttercup on Bear Hill to-day. I have certain friends whom I visit occasionally, but I commonly part from them early with a certain bitter-sweet sentiment. That which we love is so mixed and entangled with that we hate in one another that we are more grieved and disappointed, aye, and estranged from one another, by meeting than by absence. Some men may be my acquaintances merely, but one whom I have been accustomed to regard, to idealize, to have dreams about as a friend, and mix up intimately with myself, can never degenerate into an acquaintance. I must know him on that higher ground or not know him at all. We do not confess and explain, because we would fain be so intimately related as to understand each other without speech. Our friend must be broad. His must be an atmosphere coextensive with the universe, in which we can expand and breathe. For the most part we are smothered and stifled by one another. I go and see my friend and try his atmosphere. If our atmospheres do not mingle, if we repel each other strongly, it is of no use to stay.
