Jan., 1915 BIRDS OBSERVED ON PORRBSTER ISLAND, ALASKA 41 12. Phalacrocorax pelagicus pelagicus. Pelagic Cormorant. This spe- cies is fairly common along the shores of Forrester Island and to a less extent occurs on both Lawrie and South islands. Nest building commenced during ' the first week in June and eggs were in evidence by the 26th. Young birds were in the nests twenty-four days later though it is possible that the period of incubation is somewhat shorter than this. Several times at sea these birds were seen feeding on herring.

BIRDS OF THE BOSTON MOUNTAINS, ARKANSAS By AUSTIN PAUL SMITH HE FOLLOWING list consists of birds that were met with by the writer during an eighteen months residence in the region'; or of species reported to him as occurring within the area hereafter specified. The Boston Mountains comprise a range of rough hills covering the greater par t of several counties in northwestern Arkansas and extending for a short distance into Oklahoma. Essentially a part of the Ozark plateau, this group constitutes the highest land within the state, with exception of a few isolated peaks of the Ouachita Mountains, that lie south of the Arkansas River. The Boston Mountains reach an altitude of 2200 feet, in the vicinity of Wins- low, Arkansas. At least ninety percent of the area of these hills is forested; but much of it is second growth timber. Such as remains of the primitive forest is largely confined to ravines and rough hillsides; but, wherever found, it contains most of the species of deciduous arborescent growth, general to the Carolinian zone within the Mississippi watershed. On areas that have been "cut-over", and allowed to revert to forest, the principal trees are oaks of several species, in- cluding Quercus velutina, alba, rubra, and coccinea ; hickory, mostly H. glabra ; chinqhapin (Castanea pum?la); sour gum (Nyssa sylvatica); and persimmon (Diospyros virginica). Wherever clearings have been made and abandoned, a vigorous growth of sassafras now exists. Sweet gum (Liquidamber styraci- flua), sycamore (Platanus occidentalis), and elm (Ulmus american. a) are usual- ly found in the immediate vicinity of streams. The undergrowth of the larger ravines is largely, often entirely, composed of indian currant (Symphoricarpos vulgaris). The geographical area of this article is confined to a radius of ten miles of Winslow, and within the limits of Washington county, unless otherwise stated; also at an altitude of 1800 feet, or over. I have found A. H. Howell's Birds of Arkansas (Biological Survey, Bul- letin no. 38) of great assistance in preparing this list, it being the only publi- cation that has yet appeared relative to the avifauna of that state. Acknowl- edgment is also due the Bureau of Biological Survey for the identification of several of the forms included herewith. ? Anas platyrhynchos. Mallard. A flock of eight birds, closely bunched, and not more than fifty feet overhead, passed November 23, 1913. In 1914, three birds were noted as early as September 1.
