110 : EXPEDITION OF THE “ALBATROSS,” 1899-1900. 
late clay, containing much Manganese in the form of larger and smaller 
nodules and small grains, and many sharks’ teeth.' 
A peculiar assortment of large continental rock fragments more or less 
impregnated and covered with Manganese was brought up by the trawl at 
Station 2, lat. 28° 23’ N., long. 126° 57° W., 2368 fathoms, 450 miles from 
Guadalupe Island, the nearest land, where the deposit is an extremely 
pure Red Clay. These look like fragments transported by ice. 
A comparison of this map with the map published in the “Challenger” 
Report on Deep-Sea Deposits in 1891 shows at a glance that a large mass 
of information bearing upon the distribution of marine deposits has been 
collected in the interval. From the numerous surveys made under the 
auspices of the British Admiralty in the S. W. Pacific, and northeastward 
to the Sandwich Islands and the American coast, in connection with the 
British cable between Australia and British Columbia, from the work of the 
‘“ Albatross” and other ships of the U.S. Navy and U.S. Fish Commission, 
and from other sources, we have derived much information both regarding 
the depth and the deposits of the Pacific. The chief modifications on the 
deposit map of 1891 are, — 
(1) The increased area occupied by the Radiolarian Ooze, in lat. 8° to 
12’ N., extending from long. 165° to 80° W., and also in lat. 8°S. to 6° N. 
and long. 162° to 177° W. 
(2) The alterations in the form of the Globigerina Ooze areas, which 
are now, in the vicinity of the Coral Islands, more circumscribed, while the 
Red Clay is proportionally increased in area and more closely approaches 
the islands. 
(3) The introduction of Pteropod Ooze in many localities not indicated 
on the earlier map; and 
(4) The introduction of a band of Diatom Ooze in the extreme North 
Pacific Ocean, extending from off Yezo Island, Japan, hugging the Kurile 
and Aleutian Islands, to off Vancouver Island, British Columbia. “The 
existence of this Diatom Ooze band was recognized during the examination 
1 Tt is rather surprising that no Cetacean bones are included in the material from this Station, 
indeed among the material sent to us for examination no Cetacean bones have been observed, although 
Mr. Agassiz mentions.having obtained them at Stations 2 and 18.
