of the entrance to Vineyard Sound from this lighthouse across to the lightship is about seven miles. The northeastern extremity of the Elizabeth Islands is Naushon, and between it and the main land of Cape Cod are the strait and harbor formerly known to the sailor as Wood's Hole, but now refined into Wood's Holl, just as "Holmes's Hole," another popular harbor over on "the Vineyard," has since become Vineyard Haven. Both of these "holes," and particularly the latter, have always been favorite places for schooner skippers to run into and avoid adverse winds. The Elizabeth group has four large islands, the others being small. Narrow and often tortuous channels separate them. Cuttyhunk is about two and one-half miles long, and the present successor of Gosnold's ill-starred colony is a club from New York who have a seaside establishment there. Not far away, to the northward, is Penikese Island, covering about one hundred acres, which was formerly the location of Professor Agassiz's "Summer School of Natural History." East of Cuttyhunk is Nashawena, three miles long, and next comes Pasque Island, also the abiding-place of an attractive club comfortably housed. Naushon is the largest island, eight miles long, stretching from Pasque almost to Wood's Holl, and having opposite each other, on its northern and southern shores, two noted harbors of refuge, the Kettle and Tarpaulin Coves. Upon Naushon, early in the nineteenth century, lived James Bowdoin, the diplomatist and benefactor of Bowdoin College in Maine, which was named for his father. Naushon is a very pretty island, and was described in those days by a distinguished English lady traveller as "a little pocket America, a liliputian Western world, a compressed Columbia." Clustering around its northeastern extremity are some of the smaller islets of the group--the Ram Islands, and Wepecket, Uncatina and Nonamesset. The strait at Wood's Holl forms a rocky gateway leading from Buzzard's Bay into Vineyard Sound, and just beyond, on the Cape Cod shore, is its guiding beacon on the point of Nobska Hill. Wood's Holl has but a small harbor on the edge of the contracted and tortuous passage, which is full of rocks, difficult to navigate, and generally having the tide running through like a millrace. The settlement is small, displaying attractive cottages on the adjacent shores, and here are located the station and buildings of the United States Fish Commission and the Marine Biological Laboratory.
