MAINE (L. Umbagog) 1876. Friday June 23 2nd nest of Colaptes. G. Philadelphia Return to Cambridge Clear and a fine cool day. Spent most of the forenoon gathering. In P.M. took a ride over along the Essex road with Herrifor who visited my Swallow flycatcher's nest for me but found it deserted and empty, though evidently a new nest. It was placed in a Darnus at the height of about 10 ft. Later in P.M. went out to my Colaptes' nest with Purdin and took from it 6 eggs. This is a second set by the same birds, which when the first laying was finished, dug the bush down a foot deeper & commenced laying again. Purdin took 3 sets of other flocks but he brought in nothing. Saturday June 24 Clear and almost cold at sunrise. Left the lake this morning for home driving down to Bethel with Purdin in an open buggy, took a nest of Y. Swainsoni on the edge of the road, with 4 eggs nearly hatched. This nest was the one that I found with 2 eggs June 13th. We heard 8 Mourning Warblers singing between the lake house and Poplar Tavern. Most of them were between the notch and the latter place, and in one spot two was singing together within a few rods of each other. At Bethel we fell in with Prof. Morse of Salem whom P. was acquainted with. He had been taking altitudes with the barometer in & aroud the notch. The following are some of his determinations. Sparkled Mt. 4,000 ft. Saddle-back Mt. 3,700 . Road in notch 1250ft. Lake Umbagog about 800 ft. We arrived in Boston all right at 5:15 P.M.
