STATIONS FOR 1873, WITH HEADQUARTERS AT PEAK'S ISLAND, CASCO 

 BAY, MAINE; AND ALSO STATIONS OF THE UNITED STATES COAST 

 SURVEY STEAMER BACHE FOR 1872, 1873, AND 1874, IN THE GULF OF 

 MAINE, ETC. 



lu this list the dredgings indicated by the above heading have been 

 grouped together, as they appear on the chart prepared for publica- 

 tion, Numbers ranging from 1 B. to 78 B. were originally assigned to 

 the Bache dredgings for 1873 and 1874, in papers published by Profes- 

 sor Yerrill in the American Journal of Science for April, 1874, and June, 

 1875, and elsewhere. To these the dredging stations of the Bache for 

 1872, 18 in number, have been added, thus increasing the list to 97 B. 

 As to the regular series of dredgings made by the Blueliglitj under 

 command of Lieut. Commander L. A. Beardslee, in and off Oasco Bay, 

 no serial numbers were given to the hauls until the commencement of 

 the temperature observations, July 21. To the numbers (1 to QQ)^ given 

 to such of the subsequent hauls as were accompanied by temperature 

 observations, 100 has been added (101 Bl. to 166 Bl.), and numbers from 

 167 BL to 190 Bl. have been given to the hauls from July 12 to July 21, 

 and from 191 Bl. to 212 Bl. to those taken after July 20, but not in- 

 eluded in the temperature series. The descriptions of localities from 

 101 Bl. to 166 Bl. are taken from the record books for temperatures, 

 with some additions, and from 167 Bl. to 212 Bl. from the eight books 

 of dredging lists, which were kept. Additions to 101 Bl. to 166 Bl., 

 taken from the dredging books, are marked D. L. 



The dredging stations of the Bache for 1872 were on and about Saint 

 George's Bank and La Have Bank, and extended as far as Halifax, I^. 

 S.; in 1873 they were mostly in the Gulf of Maine, especially in the re- 

 gion of Jeffrey's and Cashe's Ledges, a few being made in Massachusetts 

 Bay; those for 1874 were entirely in the Gulf of Maine.
