892 REPORT OF COMMISSIONER OF FISH AND FISHERIES. [20] 



STATIONS FOR 1874 AND 1875, WITH HEADQUARTERS AT NOANK, CONN., 

 AND WOOD'S HOLL, MASS. 



In 1874, the headquarters of the United States Fish Commission were 

 established at Noank, Conn., and the area covered by its dredgings in- 

 cluded Fisher's Island Sound ; the eastern part of Long Island Sound ; 

 Block Island Sound ; and Gardiner's and Peconic Bays ; and also ex- 

 tended some distance to the east, south, and southwest of Block Island. 

 In 1875, with headquarters at Wood's Holl, Mass., dredgings were car- 

 ried on in Vineyard and Nantucket Sounds; Buzzard's Bay; over a 

 portion of Nantucket Shoals; to the southward of Nantucket Island 

 and Martha's Vineyard ; and also on and about Southwest Shoal. The 

 dredgings were all made by the United States steamer Bluelight, Com- 

 mander L. A. Beardslee, and a separate series of numbers, to designate 

 the stations, was employed for each year. To facilitate the recording 

 of all the dredging stations of the United States Fish Commission on 

 charts, and to bring the southern ones into uniformity with those made 

 to the north of Cape Cod in more recent years, and already recorded 

 both on charts and in reports prepared for publication in a single series 

 of numbers ranging from 1 to 378, 400 has been added to the 1874 

 dredgings and 600 to those of 1875. In this way all the dredging sta- 

 tions from 1S74 to 1879, inclusive, are included in a single series. 



The temperature observations recorded in the two following tables 

 were mostly taken with much care. Former experiences had proved 

 that the Miller-Casella thermometers were slow in acting, requiring from 

 three to ten minutes (according to the depth of water) to obtain a cor- 

 rect reading, and they were, therefore, always left down a suitable length 

 of time. The bottom and surface temperatures, in nearly all cases, were 

 taken with Miller-Casella self-registering thermometers; occasionally a 

 United States naval thermometer was employed for surface tempera- 

 tures, and the same instrument was generally employed for the air.
