17–23 May 1858

Yesterday walked with Henry Thoreau to the spring in Everett's pasture and found Ranuncu- lus abortivus and bulbosus, and the Equisetum htemale, scouring rush, and Saxifraga Pennsyl- vanica, and golden saxifrage; heard a note of Henry's nightwarbler and saw at Gourgas's pond two yellow-legs flying like ducks, only with a curlew cry ("telltale"), and a pair of tat- lers who continued their researches in the water without regard to our spyglasses ; saw the wood frog [Rana sylvaticd).
