 STEAMER ALBATROSS FOR 1906. 



This expedition of the Albatross covered the period from May 3 to 

 December 10, 1906. The vessel sailed from San Francisco via Seattle 

 to Dutch Harbor, Alaska ; thence to the westward, among the Aleutian 

 Islands, swinging northward and back again, to take in Bowers Bank 

 in Bering Sea : from the end of the Aleutian chain northwestward to 

 the Komandorski Islands, then to Petropaulovsk, Kamchatka; 

 thence rounding the southern point of this peninsula and up its west- 

 em coast to latitude 51° 40': from this point southwestward in the 

 Okhotsk Sea along the Kuril Islands to Hakodate, whence the course 

 was taken along the western coast of Hondo, crossing the Sea of 

 Japan to the Korean coast : thence zigzagging southward among the 

 numerous islands at the lower end of the Japanese Archipelago, 

 including the northern Linschotens: northward along the eastern 

 Japanese coast, through the Inland Sea and along the outer coast of 

 Hondo, again to Hakodate, thus completely circumnavigating 

 Hondo and Kjoshiu. From Hakodate the ship cruised northward 

 west of Hokkaido, up the western coast of Saghahn Island to latitude 

 47° 40', returning and rounding the lower end of the island to Cape 

 Patience on the eastern side; from Cape Patience south again to the 

 eastward of Hokkaido and back to Hakodate, retiurning thence to 

 Yokohama, from which point, after a -short cruise in Suruga and 

 Sagami bays, the vessel sailed for San Francisco. 



Three hundred and eighty-five stations were occupied during this 

 expedition, the work including dredging and other collecting, and 

 hydrographic and meteorological observations. Complete data for 

 each of these stations are given in the following tables. Serial tem- 

 perature records where taken are separately tabulated. 



All stations where apparatus was employed to collect natural 

 historA' material are given numbers in the "dredging" series, and 

 are indicated by the prefixed letter D. The hydrographic stations, 

 where soundings only v\'ere made, have another series of numbers and 

 are designated by the letter H. At times specimens were taken 

 with dip nets during the occupation of a hydrographic station, but, 

 on account of the irregularity of such collecting, the station was not 

 regarded as a collecting station. The last previous dredging station
