72 EXPEDITION OF THE “ALBATROSS,” 1899-1900. 
From south of Tahiti on the way to Valparaiso the “Challenger” 
also obtained manganese nodules at Stations 285, 286, 289, in 2375, 2335, 
and 2550 fathoms; and further to the east, at Stations 293 and 297, in 
2025 and 1775 fathoms. The “Challenger” also found manganese nodules 
in 2160 fathoms, about 100 miles from the coast of South America, as well 
as in the Atlantic far from continental land, and at one station in the 
Indian Ocean in 2600 fathoms; but the ‘‘ Challenger” obtained none north 
of the Equator, either in the Atlantic or in the Pacific, so that this first 
haul of ours in lat. 28° 23’ N. and long. 126° 57’ W., as well as hauls further 
south on our way to the Marquesas, greatly extend the area over which 
such deposits of manganese nodules and red clay probably exist, — areas 
which, according to Murray, are situated in deep water and far from 
continental land, too far from land to be masked by telluric deposits, and 
at too great a depth to be covered by the shells of Foraminifera and 
other pelagic animals, as suggested by Murray. The “Valdivia” obtained 
manganese nodules in the Southern Atlantic in lat. 30° 84.9’ S., long. 
6° 10.2’ W., about 2600. fathoms. 
We could find no spherules of cosmic iron in the few samples of 
manganese nodules which we ground to powder. 
In the track of great oceanic currents Globigerinw shells extend to 
greater depths, and their tests are found mixed with red clay quite 
frequently at depths quite beyond those at which they ordinarily disap- 
pear; see Stations 14 to 22, on our way to the Marquesas, where the 
deposit is a Globigerina ooze at depths far beyond those at which, accord- 
ing to. Murray, Globigerina ooze should occur,—in depths of 2776, 2440, 
2463, 2495, and 2287 fathoms. 
At Station 10, in 8088 fathoms, lat. 16° 38’ N., long. 136° 14’ W., 
we lowered the “Blake” trawl. Unfortunately there was no evidence 
of the trawl having been on the bottom, although we had as much 
wire-rope out in proportion to the depth as in other hauls. The net 
came up clean, and although it towed open through such an immense 
length of column of water, the net contained nothing which we had 
not caught with the tow-net inside of 200 fathoms from the surface. 
It had so-called deep-sea fishes, — Cyclothone and Myctophum,— and deep- -
