OGEAX TEMPEKATDEES. 163 



Body's /ofiiiK/ liijht-honse. — Located uear tho sonthcrn end of Body's Island, abont 35 miles uortb of Capo Hatteras, 

 and 8(j miles from Cape Lookout. The shore is similar iu cliaraoter to that at Capo Lookout, but tho surface observa- 

 tions were takeu where the depths are from 7 to 9 feet. The temperature curves for the surface and air are almost 

 precisely alike, and the observations cannot bo regarded as of any value with respect to the open waters ofl' shore. 



VlltGIXIA. 



Winter Quarter Shoal Uyht-ship. — Anchored iu 10+ fathoms of water, 8^ miles off Assateague Island, and about 

 midway between the entrances to Chesapeake Bay aud Delaware Bay ; distant about \iS miles from Body's Island. 



NliVir JERSEY. 



Five-Fathom Banlc light-ship. — Anchored iu 12 fathoms of water, abont 14 miles off the coast, just east of Cape Mu^ 

 and oil' the entrance to Delaware Bay ; distant about 56 miles from Winter Quarter Shoal light-ship. 



Absceon light-house. — Located on the beacb in front of Atlantic City, and just south of tho entrance to Absecoii 

 lulet ; 34| miles distant from Five Fathom Bank light-ship. The shore is faced with shoals, but the surface observa- 

 tious were takeu iu the channel leading to the inlet, iu depths of 9 to 15 feet of water. The surface records are much 

 more satisfactory than at either of the previous shore stations (Cape Lookout and Body's Island), and the surface 

 curves are nearly as regular as at Five Fathom Bank light-ship. 



NICW YORK. 



Sandy Hoolc lightship. — Anchored in 14 fathoms of water off the entrance to New York Bay ; (J miles east of Sandy 

 Hook, N. J., the nearest land ; and about 70 miles from Absecou light. 



Fire Island light-house. — Located on the east side of Fire Island Inlet, south side of Long Island, 31 miles from 

 Sandy Hook light-ship. The surface observations were taken in the entrance to Great South Bay, between Fire 

 Island and Oak Island, iu 3 feet of water. A strong current Hows through the channel, which is somewhat similar in 

 character to the entrance to Absecou Inlet. 



lillODE ISL.VND. 



liloclc Island southeast light-house. — Located at the southeastern corner of Block Island, 82 miles from Fire Island 

 light. The observations were taken at the lower edge of the beach, which faces the open sea to the south. The 

 surface temperature curves are comparatively regular aud show less variation from local iuflm-uces than would be 

 expected at a shore station of its character. 



Brenton's Beef light-ship.— knchoTcd in Hi fathoms of water, off the entrance to Nanagausfclt Bay, aud about IJ 

 miles from land ; 17f miles distant from Block Island southeast light. 



MASSACHUSETTS. 



Vineyard Sound lighl-sliip. — Anchored in 15 fathoms of water, on the western side of the southern eutrauce to 

 Vineyard Sound, di miles from Cuttyhuuk Island, the nearest laud, aud 17^ miles from Brenton's Reef light-ship. 



Nantueket Neie South Shoal light-ehip. — Anchored in 16 to 18 fathoms, at the southern edge of Nantucket shoals, 

 and 21 miles southeast of Nantucket Island, the nearest land ; distant about 58 miles from Vineyard Sound light-ship. 

 This station occupies a very imiJortaut position with reference to the ofl-shore fisheries. 



Follock Hip light-ship. — Anchored in 5 to 7 fathoms of water, iu the eastern eutrauce to Nantucket Sound, aud 3J 

 miles SE. by E. ^ E. from Monomoy Point light-house. Cape Cod ; distant abont 36 miles from Nantucket New South 

 Shoal light-.ship. This light-ship is mostly surrounded by numerous shoals which are separated by channels occupied 

 by strong tidal currents. 



Thatcher's Island ii(//i(s.— Located ou Thatcher's Island, olf the eastern extremity of Cape Ann, about 73 miles from 

 Pollock Kip light-ship. Depths of 60 fathoms occur within a distance of 6| miles to the eastward. The surface tem- 

 perature observatious were taken where the water is 7 feet deep, and show variations from local influences. Obser- 

 vations were first made at this station by one of the light-house keepers, but after April, 1881, by an observer of the 

 U. S. Signal Service. 



MAINE. 



Boon Inland liglit-house. — Boon Island is a small rocky island lying off York Harbor, and 5f miles from the nearest 

 janil. It is distant about 35 miles from Thatcher's Island, and. is surrounded by depths of SJ to 25 fathoms within a 

 radius ofl mile. The depth of water where the surface observations were taken is 9 feet. Many gai)s occur iu the 

 records of this station, aud the reductions plotted on the chart are therefore probably not reliable. 



Seguin Island lighthouse. ^Seguin Island is small and rocky, aud is situated about 2i miles off the nearest point 

 of the mainland, on the eastern side of the entrance to Kennebec Eiver, and about 47 miles from Boon Island. The 

 light-house is on the western side of the island, where the water is from 6 to 8 fathoms deep close inshore at the 

 place of observation. 



Matinicus Boek light-house. — Mafinicus Bock is a rocky islet about 14 miles south of Viual Haven, at the mouth of 

 Penobscot Bay, and about 80 luiles from Seguiu Island. Depths of 4 to 45 fathoms occur within a radius of 1 mile, 

 the depth where the surface observatious where taken rauging from 6 to 12 fathoms. 



Mount Desert Bock light-house. — Mount Desert Rock is similar iu character to Matinicus Rock, and io situated 

 about IS miles otl' Moiuit Desert Island and 34 miles from Matinieus Rock. Within a radius of 5 miles the depths
