THE ' ' ALBATROSS ' ' PHILIPPINE EXPEDITION V 



marine forms, noteworthy collections of land plants and land animals, 

 especially birds, reptiles, and mollusks, were made, mostly by or 

 under the immediate direction of Dr. Paul Bartsch. 



In 1910 there was published Dredging and Hydrographic Records 

 of the United States Bureau of Fisheries Steamer Albatross during the 

 Philippine Expedition, 1907-1910 (Bureau of Fisheries Document No. 

 741, 97 pp.) This publication gives for each station occupied data as 

 to the locality, date, time of day, depth of water, character of bottom, 

 surface and bottom densities, apparatus used, duration of trial and 

 depth at which apparatus was employed, and other particulars of the 

 operations at sea, at anchorages, and on shores and reefs. It appears 

 that 577 dredging stations were established, of which 220 were at 

 depths of less than 100 fathoms, 120 at 100 fathoms or more but less 

 than 200 fathoms, 153 between 200 and 499 fathoms, 72 between 

 500 and 999 fathoms, and 12 at over 1,000 fathoms. The greatest 

 depths at which dredging was done were 1,804 fathoms in the China 

 Sea off Formosa, 2,275 fathoms in the Sulu Sea, and 1,560 fathoms in 

 the Molucca Sea. The hydrographic stations numbered 41. At these 

 no apparatus for collecting natural history specimens was employed, 

 although at times dip nets were incidentally used during the occupa- 

 tion of such stations; the usual physical data obtained as at dredging 

 stations, including a sample of the bottom, were secured. Hydro- 

 graphic stations of special interest, at which Lucas' sounding machine 

 and Sigsbee sounding rod were used, were one of 1,570 fathoms in 

 the Sulu Sea off Mindanao and three of 1,220, 1,498, and 1,758 fath- 

 oms in the China Sea off Hong Kong. 



Immediately on the arrival of the collections in Washington, 

 arrangements were made with specialists in America, Europe, and 

 Asia for studying and reporting on them. The collections in some 

 cases were assigned by the Bureau of Fisheries, in other cases they 

 were transferred to the United States National Museum and by it 

 assigned for study and report. 



The series of reports on the aquatic resources of the Philippines 

 and contiguous regions have been published as parts of Bulletin No. 

 100 of the United States National Museum. Some 23 such reports 

 have been issued and others are in course of preparation and print- 

 ing. For convenience, the reports are now bound together in vol- 

 umes with separate title-pages, tables of contents, and indexes. 



With the issuance of the outstanding reports, there will be pub- 

 lished a general review of the scientific results of the Albatross 

 Philippine Expedition.

 Director of the Expedition.
