March 11.
C. says that Walden is almost entirely open to-day, so that the lines on my map would not strike any ice, but that there is ice in the deep cove.
It will be open then the 12th or 13th.
This is earlier than I ever knew it to open.
Fair Haven was solid ice two or three days ago, and probably is still, and Goose Pond is to - day all ice.
Why, then, should Walden have broken up thus early? for it froze over early and the winter was steadily cold up to February at least.
I think it must have been because the ice was uncommonly covered with snow, just as the earth was, and as there was little or no frost in the earth, the ice also was thin, and it did not increase upward with snow ice as much as usual because there was no thaw or rain at all till February 2d, and then very little.
According to all accounts there has been no skating on Walden the past winter on account of the snow. It was unusually covered with snow.
This shows how many things are to be taken into account in judging of such a pond.
I have not been able to go to the pond the past winter.
I infer that, if it has broken up thus early, it must be because the ice was thin, and that it was thin not for want of cold generally, but because of the abundance of snow which lay on it.
The water is now high on the meadows and there is no ice there, owing to the recent heavy rains.
Yet C. thinks it has been higher a few weeks since.
C. observes where mice (?) have gnawed the pitch pines the past winter. Is not this a phenomenon of a winter of deep snow only? as that when I lived at Walden, a hard winter for them. I do not commonly observe it on a large scale.
My Aunt Sophia, now in her eightieth year, says that when she was a little girl my grandmother, who lived in Keene, N. H., eighty miles from Boston, went to Nova Scotia, and, in spite of all she could do, her dog Bob, a little black dog with his tail cut off, followed her to Boston, where she went aboard a vessel.
Directly after, however, Bob returned to Keene.
One day, Bob, lying as usual under his mistress's bed in Keene, the window being open, heard a dog bark in the street, and instantly, forgetting that he was in the second story, he sprang up and jumped out the chamber window. He came down squarely on all fours, but it surprised or shocked him so that he did not run an inch, --- which greatly amused the children, - my mother and aunts.
The seed of the willow is exceedingly minute, - as I measure, from one twentieth to one twelfth of an inch in length by one fourth as much in width, - and is surrounded at base by a tuft of cotton - like hairs about one fourth of an inch long rising around and above it, forming a kind of parachute. These render it the most buoyant of the seeds of any of our trees, and it is borne the furthest horizontally with the least wind.
It falls very slowly even in the still air of a chamber, and rapidly ascends over a stove. It floats the most like a mote of any, — in a meandering manner, — and, being enveloped in this tuft of cotton, the seed is hard to detect.
Each of the numerous little pods, more or less ovate and beaked, which form the fertile catkin is closely packed with down and seeds. At maturity these pods open their beaks, which curve back, and gradually discharge their burden like the milkweed. It would take a delicate gin indeed to separate these seeds from their cotton.
If you lay bare any spot in our woods, however sandy, as by a railroad cut, no shrub or tree is surer to plant itself there sooner or later than a willow (commonly S. humilis or tristis) or poplar.
We have many kinds, but each is confined to its own habitat. I am not aware that the S. nigra has ever strayed from the river's brink. Though many of the S. alba have been set along our causeways, very few have sprung up and maintained their ground elsewhere.
The principal habitat of most of our species, such as love the water, is the river's bank and the adjacent river meadows, and when certain kinds spring up in an inland meadow where they were not known before, I feel pretty certain that they come from the river meadows.
I have but little doubt that the seed of four of those that grow along the railroad causeway was blown from the river meadows, viz. S. pedicellaris, lucida, Torreyana, and petiolaris.
The barren and fertile flowers are usually on separate plants. I observe [?] that the greater part of the white willows set out on our causeways are sterile ones.
You can easily distinguish the fertile ones at a distance when the pods are bursting.
And it is said that no sterile weeping willows have been introduced into this country, so that it cannot be raised from the seed.
Of two of the indigenous willows common along the brink of our river I have detected but one sex.
The seeds of the willow thus annually fill the air with their lint, being wafted to all parts of the country, and, though apparently not more than one in many millions gets to be a shrub, yet so lavish and persevering is Nature that her purpose is completely answered.

See Walden ("In 1845 Walden was first completely open on the 1st of April; in '46, the 25th of March; in '47, the 8th of April; in '51, the 28th of March; in '52, the 18th of April; in '53, the 23rd of March; in '54, about the 7th of April. "); April 18, 1856 ("Walden is open entirely to-day for the first time, owing to the rain of yesterday and evening. I have observed its breaking up of different years commencing in ’45, and the average date has been April 4th. ") NoeFrom 1995 to 2015, ice out ranged from Jan. 29 in the record-breaking warm winter of 2012 to as late as April 12. The median ice out date over that period was March 21.

C. observes where mice (?) have gnawed the pitch pines the past winter. See January 23, 1852 ("Mice have nibbled the buds of the pitch pines, where the plumes have been bent down by the snow."); April 8, 1861 ("The pitch pines have been much gnawed or barked this snowy winter . . . At the base of each, also, is a quantity of the mice droppings. It is probably the white-footed mouse. ") See also A Book of the Seasons, by Henry Thoreau, The Wild Mouse
