UPTON, MAINE 1871 The town of Upton is situated at the foot of Lake Umbagog and consists of a few scattered houses only. The adjacent country which we made our collecting ground is one vast valley with sloping hills on every side towering into mountains in the distance. To the South about a dozen miles is a range of lofty mountains which apparently forms the limit of the range of many species of birds and mammals. Sceirus Carolinenis, for instance, is said to be seldom taken North of this range and Pyranga rubra rarely strays beyond it; through this the road passes by a narrow gorge with "Saddleback" mountain on the right, and a decided change of fauna is immediately per- ceptible; Dol. orizivorus becomes very scarce and Cyanospiza Cyanea quite disappears: De. maculosa is quite abundant all the way up although we did not detect it at Bethel the start- ing point of our stage ride. At that place we found T.Suain- soni, S.noveboracensis, L.albicollis, T.fuscescens, P.savanna, my.canadensis, G.trichas, D.Pennsylvanica, D.aestiva and many other species abundant and settled for the season. D.Black- burniae was numerous in the blossoming apple trees, but appar- extly migrating. D.striata was also common and we took one of E.flaviventris, but were unable to detect D.castanea. Icterus baltimore and V.gilvus common here, we saw no further up the valley. E.Trailli commenced a few miles to the North and was heard as far as the Poplar Tavern at Newcry where we secured two June 10th. Why it did not occur at the Lake I do not un- derstand as the alder runs its favorite resort were there abun- dant.
