We next crossed to the northern end of Great Island land- ing first on the western side of the cove to visit a Warbler's nest found on the 11th in a big hemlock fully 60 feet high. Watrous reached it with some difficulty when it proved to be an old nest apparently of D. castanea! We have had many such disappointments of late. A similar-looking nest, found by Watrous on the 11th in a large red spruce 200 yards or more back from the water on the opposite side of the cove, was next visited. It turned out to be a Bay-breast's containing a fine set of 5 fresh eggs. The nest was fully 50 feet above the ground near the end of a stout, drooping branch about 15 feet from the main trunk. Watrous reached this nest by climbing a tall, slender maple which, by the aid of a rope, Jim and Gilbert drew over and held within arm's reach of the nest.
