What the delicate pinkish and yellowish flower with hoary-green stem and leaves, of rocky hills.[182]

Saw Bunker Hill Monument and Charlestown from the Wayland hills, and across the valleys to Milton Hill.[183] Westward, or west by south, an island in a pond or in the river (!which see!) A grand horizon. Probably saw the elm between Wayland and Weston which is seen so far in the horizon from the northwest part of Sudbury. A good, a rare place this must be to view the Sudbury or Wayland meadows a little earlier.

Came back across lots to the black spruce.

Now, at 8.30 o’clock p. m., I hear the dreaming of the frogs.[184] So it seems to me, and so significantly passes my life away. It is like the dreaming of frogs in a summer evening.

May 27. I saw an organ-grinder this morning before a rich man’s house, thrilling the street with harmony, loosening the very paving-stones and tearing the routine of life to rags and tatters, when the lady of the house shoved up a window and in a semiphilanthropic tone inquired if he wanted anything to eat. But he, very properly it seemed to me, kept on grinding and paid no attention to her question, feeding her ears with melody unasked for. So the world shoves up its window and interrogates the poet, and sets him to gauging ale casks in return. It seemed to me that the music suggested that the recompense should be as fine as the gift. It would be much nobler to enjoy the music, though you paid no money for it, than to presume always a beggarly relation. It is after all, perhaps, the best instrumental music that we have.

May 28. The trees now begin to shade the streets. When the sun gets high in the sky the trees give shade. With oppressive heats come refreshing shadows.

The buttercups spot the churchyard.

May 29. It is evident that the virtues of plants are almost completely unknown to us, and we esteem the few with which we are better acquainted unreasonably above the many which are comparatively unknown to us. Bigelow says: “It is a subject of some curiosity to consider, if the knowledge of the present Materia Medica were by any means to be lost, how many of the same articles would again rise into notice and use. Doubtless a variety of new substances would develop unexpected powers, while perhaps the poppy would be shunned as a deleterious plant, and the cinchona might grow unmolested upon the mountains of Quito.” Sawyer regards Nux vomica among the most valuable. B. says (1817): “We have yet to discover our anodynes and our emetics, although we abound in bitters, astringents, aromatics, and demulcents. In the present state of our knowledge we could not well dispense with opium and ipecacuanha, yet a great number of foreign drugs, such as gentian, columbo, chamomile, kino, catechu, cascarilla, canella, etc., for which we pay a large annual tax to other countries, might in all probability be superseded by the indigenous products of our own. It is certainly better that our own country people should have the benefit of collecting such articles, than that we should pay for them to the Moors of Africa, or the Indians of Brazil.”

The thorn-apple (Datura Stramonium) (apple of Peru, devil’s-apple, Jamestown-weed) “emigrates with great facility, and often springs up in the ballast of ships, and in earth carried from one country to another.” It secretes itself in the hold of vessels and migrates. It is a sort of cosmopolitan weed, a roving weed. What adventures! What historian knows when first it came into a country! He quotes Beverly’s “History of Virginia” as saying that some soldiers in the days of Bacon’s rebellion, having eaten some of this plant, which was boiled for salad by mistake, were made natural fools and buffoons by it for eleven days, without injury to their bodies (? ?).

The root of a biennial or perennial will accumulate the virtues of the plant more than any other part.
