P. M. - To Walden.
Very hot. The piper grass bloom in prime. Examined the flying squirrel’s nest at the base of a small white [oak] or two (sprouts), four inches through, in a small old white oak stump, half open above, just below the level of the ground, composed of quite a mass of old withered oak leaves and a few fresh green ones, and the inside wholly of fine, dry sedge and sedge-like bark-fibres. The upper side of the nest was half visible from above. It was eight or nine inches across. In it I found the wing of an Attacus luna, - and July 1st another wing near Second Division, which makes three between June 27th and July 1st.
At the railroad spring in Howard’s meadow, I see two chestnut-sided warblers hopping and chipping as if they had a nest, within six feet of me, a long time. No doubt they are breeding near. Yellow crown with a fine dark longitudinal line, reddish-chestnut sides, black triangle on side of head, white beneath.
River falls several inches.
