_Oct. 29th, 30th, and 31st_.--Wonderfully fine, with the full harvest moon, dazzling and silvery. I have haunted the river every night lately, where I could get a look at the bridge by moonlight. It is indeed a structure of perfection and beauty unsurpassable, and I never tire of it. The river at present is very low; I noticed to-day it had much more of a blue-clear look than usual. I hear the slight ripples, the air is fresh and cool, and the view, up or down, wonderfully clear, in the moonlight. I am out pretty late: it is so fascinating, dreamy. The cool night-air, all the influences, the silence, with those far-off eternal stars, do me good. I have been quite ill of late. And so, well-near the centre of our national demesne, these night views of the Mississippi. UPON OUR OWN LAND "Always, after supper, take a walk half a mile long," says an old proverb, dryly adding, "and if convenient let it be upon your own land." I wonder does any other nation but ours afford opportunity for such a jaunt as this? Indeed has any previous period afforded it? No one, I discover, begins to know the real geographic, democratic, indissoluble American Union in the present, or suspect it in the future, until he explores these Central States, and dwells awhile observantly on their prairies, or amid their busy towns, and the mighty father of waters. A ride of two or three thousand miles, "on one's own land," with hardly a disconnection, could certainly be had in no other place than the United States, and at no period before this. If you want to see what the railroad is, and how civilization and progress date from it--how it is the conqueror of crude nature, which it turns to man's use, both on small scales and on the largest--come hither to inland America. I return'd home, east, Jan. 5, 1880, having travers'd, to and fro and across, 10,000 miles and more. I soon resumed my seclusions down in the woods, or by the creek, or gaddings about cities, and an occasional disquisition, as will be seen following. EDGAR POE'S SIGNIFICANCE _Jan. 1, '80_.--In diagnosing this disease called humanity--to assume for the nonce what seems a chief mood of the personality and writings of my subject--I have thought that poets, somewhere or other on the list, present the most mark'd indications. Comprehending artists in a mass, musicians, painters, actors, and so on, and considering each and all of them as radiations or flanges of that furious whirling wheel, poetry, the centre and axis of the whole, where else indeed may we so well investigate the causes, growths, tally-marks of the time--the age's matter and malady?
