I have been to-night with Anthony Wright to look through Perez Blood’s telescope a second time. A dozen of Blood’s neighbors were swept along in the stream of our curiosity. One who lived half a mile this side said that Blood had been down that way within a day or two with his terrestrial, or day, glass, looking into the eastern horizon [at] the hills of Billerica, Burlington, and Woburn. I was amused to see what sort of respect this man with a telescope had obtained from his neighbors, something akin to that which savages award to civilized men, though in this case the interval between the parties was very slight. Mr. Blood, with his skull-cap on, his short figure, his north European figure, made me think of Tycho Brahe. He did not invite us into his house this cool evening,—men nor women,—nor did he ever before to my knowledge. I am still contented to see the stars with my naked eye. Mr. Wright asked him what his instrument cost. He answered, “Well, that is something I don’t like to tell.” (Stuttering or hesitating in his speech a little as usual.) “It is a very proper question, however.” “Yes,” said I, “and you think that you have given a very proper answer.”

Returning, my companion, Wright, the sexton, told me how dusty he found it digging a grave that afternoon,—for one who had been a pupil of mine. For two feet, he said, notwithstanding the rain, he found the soil as dry as ashes.

With a certain wariness, but not without a slight shudder at the danger oftentimes, I perceive how near I had come to admitting into my mind the details of some trivial affair, as a case at court; and I am astonished to observe how willing men are to lumber their minds with such rubbish,—to permit idle rumors, tales, incidents, even of an insignificant kind, to intrude upon what should be the sacred ground of the thoughts. Shall the temple of our thought be a public arena where the most trivial affairs of the market and the gossip of the tea-table is discussed,—a dusty, noisy, trivial place? Or shall it be a quarter of heaven itself, a place consecrated to the service of the gods, a hypæthral temple? I find it so difficult to dispose of the few facts which to me are significant, that I hesitate to burden my mind with the most insignificant, which only a divine mind could illustrate. Such is, for the most part, the news,—in newspapers and conversation. It is important to preserve the mind’s chastity in this respect. Think of admitting the details of a single case of the criminal court into the mind, to stalk profanely through its very sanctum sanctorum for an hour, aye, for many hours! to make a very bar-room of your mind’s inmost apartment, as if for a moment the dust of the street had occupied you, aye, the very street itself, with all its travel, passed through your very mind of minds, your thoughts’ shrine, with all its filth and bustle! Would it not be an intellectual suicide? By all manner of boards and traps, threatening the extreme penalty of the divine law, excluding trespassers from these grounds, it behooves us to preserve the purity and sanctity of the mind.[219] It is so hard to forget what it is worse than useless to remember. If I am to be a channel or thoroughfare, I prefer that it be of the mountain springs, and not the town sewers,—the Parnassian streams. There is inspiration, the divine gossip which comes to the ear of the attentive mind from the courts of heaven; there is the profane and stale revelation of the bar-room and the police court. The same ear is fitted to receive both communications. Only the character of the individual determines to which source chiefly it shall be open and to which closed. I believe that the mind can be profaned by the habit of attending to trivial things, so that all our thoughts shall be tinged with triviality. They shall be dusty as stones in the street. Our very minds shall be paved and macadamized, as it were, their foundation broken into fragments for the wheels of travel to roll over. If we have thus desecrated ourselves, the remedy will be, by circumspection and wariness, by our aspiration and devotion, to consecrate ourselves, to make a fane of the mind. I think that we should treat our minds as innocent and ingenuous children whose guardians we are,—be careful what objects and what subjects we thrust on their attention. Even the facts of science may dust the mind by their dryness, unless they are in a sense effaced each morning, or rather rendered fertile by the dews of fresh and living truth. Every thought that passes through the mind helps to wear and tear it, and to deepen the ruts, which, as in the streets of Pompeii, evince how much it has been used. How many things there are concerning which we might well deliberate whether we had better know them![220] Routine, conventionality, manners, etc., etc.,—how insensibly an undue attention to these dissipates and impoverishes the mind, robs it of its simplicity and strength, emasculates it!

Knowledge does not come to us by details but by lieferungs from the gods. What else is it to wash and purify ourselves? Conventionalities are as bad as impurities.[221] Only thought which is expressed by the mind in repose—as it were, lying on its back and contemplating the heavens—is adequately and fully expressed. What are sidelong, transient, passing half-views? The writer expressing his thought must be as well seated as the astronomer contemplating the heavens; he must not occupy a constrained position. The facts, the experience, we are well poised upon! which secures our whole attention!

The senses of children are unprofaned. Their whole body is one sense; they take a physical pleasure in riding on a rail, they love to teeter. So does the unviolated, the unsophisticated mind derive an inexpressible pleasure from the simplest exercise of thoughts.

I can express adequately only the thought which I love to express. All the faculties in repose but the one you are using, the whole energy concentrated in that. Be ever so little distracted, your thoughts so little confused, your engagements so few, your attention so free, your existence so mundane, that in all places and in all hours you can hear the sound of crickets in those seasons when they are to be heard. It is a mark of serenity and health of mind when a person hears this sound much,—in streets of cities as well as in fields. Some ears never hear this sound; are called deaf. Is it not because they have so long attended to other sounds?

July 8. Tuesday. Walked along the Clamshell bank after sundown. A cloudy sky. The heads of the grass in the pasture behind Dennis’s have a reddish cast, but another grass, with a lighter-colored stem and leaves, on the higher parts of the field gives a yellowish tinge to those parts, as if they reflected a misty sunlight. Even much later in the night these light spots were distinguishable. I am struck by the cool, juicy, pickled-cucumber green of the potato-fields now. How lusty these vines look! The pasture naturally exhibits at this season no such living green as the cultivated fields. I perceive that flower of the lowlands now, with a peculiar leaf and conspicuous white umbels.[222]

Here are mulleins covering a field (the Clamshell field) where three years [ago] were none noticeable, but a smooth uninterrupted pasture sod. Two years ago it was plowed for the first time for many years, and millet and corn and potatoes planted, and now where the millet grew these mulleins have sprung up. Who can write the history of these fields? The millet does not perpetuate itself, but the few seeds of the mullein, which perchance were brought here with it, are still multiplying the race.
