_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?
