25 UPTON, MAINE 1872 June 2 - 14 lar sapling. E. minimus. Abundant but locally distributed: not found in the forest depths. E. flaviventris. Heard at last the bona fide song of the male, a single sl-ap, something like the che bee of E. minimus, and repeated at intervals of about 20 seconds.

T. fuscens. Found them rather common up along Cambridge river. T. swainsonii. Very common everywhere: usually sang low down and had a habit of flitting a few feet at the end of each utter-
