Thoreau's manner of botanizing was, like most of his habits, somewhat singular. His vasculum was his straw-hat. "I never used any other," he writes, "and when some whom I visited were evidently surprised at its dilapidated look, as I deposited it on their front entry-table, I assured them it was not so much my hat as my botany-box." With this vasculum he professed himself more than content. I am inclined to think that my hat, whose lining is gathered in midway so as to make a shelf, is about as good a botany-box as I could have; and there is something in the darkness and the vapours that arise from the head--at least, if you take a bath--which preserves flowers through a long walk. Flowers will frequently come fresh out of this botany-box at the end of the day, though they have had no sprinkling. The joy of meeting with a new plant, a sensation known to all searchers after flowers, is more than once mentioned in the _Journal_: the discovery of a single flower hitherto unknown to him makes him feel as if he were in a wealth of novelties. "By the discovery of one new plant all bounds seem to be infinitely removed." He notes, too, the not uncommon experience, that a flower, once recognized, is likely soon to be re-encountered. Seeing something blue, or glaucous, in a swamp, he approaches it, and finds it to be the _Andromeda polifolia_, which had been shown him, only a few days before, in Emerson's collection; now he sees it in abundance. At times he adopts the method of sitting quietly and looking around him, on the principle that "as it is best to sit in a grove and let the birds come to you, so, as it were, even the flowers will come." Swamps were among Thoreau's favourite haunts: he thinks it would be a luxury to stand in one, up to his chin, for a whole summer's day, scenting the sweet-fern and bilberries. "That is a glorious swamp of Miles's," he remarks; "the more open parts, where the dwarf andromeda prevails. . . . These are the wildest and richest gardens that we have." The fields were less trustworthy, because of the annual vandalism of the mowing. "About these times," he writes in June, "some hundreds of men, with freshly sharpened scythes, make an irruption into my garden when in its rankest condition, and clip my herbs all as close as they can; and I am restricted to the rough hedges and worn-out fields which had little to attract them." Among Thoreau's best-beloved flowers, if we may judge by certain passages of the _Journal_, was the large white bindweed (_convolvulus sepium_), or "morning-glory." "It always refreshes me to see it," he writes; "I associate it with holiest morning hours. It may preside over my morning walks and thoughts." Not less worthily celebrated by him, in another mood, are the wild rose and the water-lily.
