The river is only half an inch above summer level.

The meadow-sweet and hardhack have begun to leaf.

H. D. Thoreau, Journal, April 24, 1860


The river is only half an inch above summer level. See April 24, 1852 ("The water is still over the causeway on both sides of Carlisle Bridge for a long distance. It is a straight flood now for about four miles.");  April 24, 1857 ("The water is at its height, higher than before this year.") See aksi April 1, 1858 ("The river is at summer level; has not been up this spring, and has fallen to this.")

 The meadow-sweet and hardhack have begun to leaf. See  April 24, 1852 ("The leaves of the hardhack, curled up, show their white under sides");April 24, 1855 ("The Salix alba begins to leaf. "); April 24, 1856 ("The earliest gooseberry leaf has spread a third of an inch or more.") See also April 25, 1859 ("I see the meadow-sweet, thimble-berry (even in a swamp), high blackberry, and (on a dry rock in the woods in a sunny place) some Vaccinium Pennsylvanicum leafing (even the last) apparently two or three days "); May 4, 1852 ("The meadow-sweet begins to leave out") See also A Book of the Seasons, by Henry Thoreau, Spring leaf-out.
