The thick heads of the yellow dock warn me of the lapse of time.

Here are some rich rye-fields waving over all the land, their heads nodding in the evening breeze with an apparently alternating motion; i. e. they do not all bend at once by ranks, but separately, and hence this agreeable alternation. How rich a sight this cereal fruit, now yellow for the cradle,—flavus! It is an impenetrable phalanx. I walk for half a mile beside these Macedonians, looking in vain for an opening. There is no Arnold Winkelried to gather these spear-heads upon his breast and make an opening for me. This is food for man. The earth labors not in vain; it is bearing its burden. The yellow, waving, rustling rye extends far up and over the hills on either side, a kind of pinafore to nature, leaving only a narrow and dark passage at the bottom of a deep ravine. How rankly it has grown! How it hastes to maturity! I discover that there is such a goddess as Ceres. These long grain-fields which you must respect,—must go round,—occupying the ground like an army. The small trees and shrubs seen dimly in its midst are overwhelmed by the grain as by an inundation. They are seen only as indistinct forms of bushes and green leaves mixed with the yellow stalks. There are certain crops which give me the idea of bounty, of the Alma Natura.[223] They are the grains. Potatoes do not so fill the lap of earth. This rye excludes everything else and takes possession of the soil. The farmer says, “Next year I will raise a crop of rye;” and he proceeds to clear away the brush, and either plows it, or, if it is too uneven or stony, burns and harrows it only, and scatters the seed with faith. And all winter the earth keeps his secret,—unless it did leak out somewhat in the fall,—and in the spring this early green on the hillsides betrays him. When I see this luxuriant crop spreading far and wide in spite of rock and bushes and unevenness of ground, I cannot help thinking that it must have been unexpected by the farmer himself, and regarded by him as a lucky accident for which to thank fortune. This, to reward a transient faith, the gods had given. As if he must have forgotten that he did it, until he saw the waving grain inviting his sickle.

July 9. When I got out of the cars at Porter’s, Cambridge, this morning, I was pleased to see the handsome blue flowers of the succory or endive (Cichorium Intybus), which reminded me that within the hour I had been whirled into a new botanical region. They must be extremely rare, if they occur at all, in Concord. This weed is handsomer than most garden flowers. Saw there also the Cucubalus Behen, or bladder campion, also the autumnal dandelion (Apargia autumnalis).

Visited the Observatory. Bond said they were cataloguing the stars at Washington (?), or trying to. They do not at Cambridge; of no use with their force. Have not force enough now to make mag[netic] obs[ervations]. When I asked if an observer with the small telescope could find employment, he said, Oh yes, there was employment enough for observation with the naked eye, observing the changes in the brilliancy of stars, etc., etc., if they could only get some good observers. One is glad to hear that the naked eye still retains some importance in the estimation of astronomers.

Coming out of town,—willingly as usual,—when I saw that reach of Charles River just above the depot, the fair, still water this cloudy evening suggesting the way to eternal peace and beauty, whence it flows, the placid, lake-like fresh water, so unlike the salt brine, affected me not a little. I was reminded of the way in which Wordsworth so coldly speaks of some natural visions or scenes “giving him pleasure.” This is perhaps the first vision of elysium on this route from Boston. And just then I saw an encampment of Penobscots, their wigwams appearing above the railroad fence, they, too, looking up the river as they sat on the ground, and enjoying the scene. What can be more impressive than to look up a noble river just at evening,—one, perchance, which you have never explored,—and behold its placid waters, reflecting the woods and sky, lapsing inaudibly toward the ocean; to behold as a lake, but know it as a river, tempting the beholder to explore it and his own destiny at once? Haunt of waterfowl. This was above the factories,—all that I saw. That water could never have flowed under a factory. How then could it have reflected the sky?

July 10. A gorgeous sunset after rain, with horizontal bars of clouds, red sashes to the western window, barry clouds hanging like a curtain over the window of the west, damask. First there is a low arch of the storm clouds in the west, under which is seen the clearer, fairer, serener sky and more distant sunset clouds, and under all, on the horizon’s edge, heavier, massive dark clouds, not to be distinguished from the mountains. How many times I have seen this kind of sunset,—the most gorgeous sight in nature! From the hill behind Minott’s I see the birds flying against this red sky, the sun having set; one looks like a bat. Now between two stupendous mountains of the low stratum under the evening red, clothed in slightly rosaceous amber light, through a magnificent gorge, far, far away, as perchance may occur in pictures of the Spanish coast viewed from the Mediterranean, I see a city, the eternal city of the west, the phantom city, in whose streets no traveller has trod, over whose pavements the horses of the sun have already hurried, some Salamanca of the imagination. But it lasts only for a moment, for now the changing light has wrought such changes in it that I see the resemblance no longer.

A softer amber sky than in any picture. The swallows are improving this short day, twittering as they fly, and the huckleberry-bird[224] repeats his jingling strain, and the song sparrow, more honest than most.

I am always struck by the centrality of the observer’s position. He always stands fronting the middle of the arch, and does not suspect at first that a thousand observers on a thousand hills behold the sunset sky from equally favorable positions.

And now I turn and observe the dark masses of the trees in the east, not green but black. While the sun was setting in the west, the trees were rising in the east.

I perceive that the low stratum of dark clouds under the red sky all dips one way, and to a remarkable degree presents the appearance of the butt ends of cannons slanted toward the sky, thus:—
