[5j LISTS OF DREDGING STATIONS. 877 



LISTS OF THE DREDGING STATIONS OF THE U. S. FISH 

 COMMISSION FROM 1871 TO 1879, INCLUSIVE, WITH TEM- 

 PERATURE AND OTHER OBSERVATIONS. 



[Arranged for publication by Sanderson Smith and Richard Rathbun.] 



The following lists include all the recorded dredging stations made 

 by, or in connection with, the United States Fish Commission, from 

 its organization up to date. The stations are, for the most part, ar- 

 ranged chronologically, and are designated by four series of numbers or 

 letters, as follows: One series of numbers, from IV to 87 V, with letters 

 appended, represents the stations for 1871. The 1872 stations (in the 

 Bay of Fundy) are designated by letters from t to z. Those for 1873 

 are indicated by a second series of numbers, from 1 to 212, with B. 

 (Bache) or Bl. (Bluelight) added, according as the dredgings were car- 

 ried on from the steamers Bache or Bluelight. In this series, however, 

 are also included the stations of the Bache for 1S72 and 1871, as well as 

 those for 1873. The last series combines all the stations from 1874 to 

 1879, inclusive (omitting 1876, during which year sea-work was sus- 

 pended), in numbers running from 1 to 7G9. For the sake of obtaining 

 greater uniformity in recording the stations on charts, as explained fur- 

 ther on, the stations for 1871 and 1875, originally numbered separately, 

 have been united with those from 1877 to 1879, and given numbers fol- 

 lowing 1879. The numbers for these later years run as follows: 1874, 

 from 400 to 580; 1875, from GOO to 769; 1877, from 1 to 128; 1878, from 

 129 to 238; 1879, from 239 to 378. 



The stations of the Speedwell for 1877, 1878, and 1879 are indicated 

 by numbers only, and are readily distinguished from those of the Bache 

 and Bluelight, which have B. or Bl. affixed to them. In the following 

 tables the localities given are taken from the original record books, 

 whenever such exist (i. e., for all the work of the Speedwell and much 

 of that of the Bluelight — 101 Bl. to 166 BL), with some other uotes added 

 to facilitate the finding of the localities on the chart. In many cases the 

 positions were marked, at the time, on the steamers' charts by the com- 

 manding officer, and all such positions have been adopted, even though 

 differing somewhat from those given by the record books. From the 

 nature of the operations of dredging and trawling, it becomes almost
