80 EXPEDITION OF THE "ALBATROSS," 1809-1900. 



One cannot fail to notice the frequent occurrence of particles of man- 

 ganese and of small manganese nodules in the deposits through the Pau- 

 motus and Society Islands. 



In the deep water between Nine and Tonga which culminates at Station 

 186 (lat. 21° IS' S., long. 173° 51' W.) in 4540 fathoms, we meet with red- 

 clay deposits containing Radiolaria, as at Stations 183 (lat. 19° 04' S. long. 

 167° 41' W.), 184, and 185 in 2472, 3141, and 4173 fathoms, though at 

 Station 182 the red clay in 2882 fathoms contained a considerable percent- 

 age of Globigerinje. 



On the way from Vavau to Fiji we found volcanic mud to the westward 

 of Lette while crossing the volcanic ridge which runs parallel to the Tonga 

 Islands PLateau. Crossing the eastern Fiji Plateau we meet with deposits 

 of coarse coral-sand, Pteropod ooze, and fine coral-ooze, associated with man- 

 ganese particles and Globigerinaa, much as in the deposits of the Pauuiotus. 



On our way through the Ellice and Gilbert Islands to Jaluit we obtained 

 in the proximity of the islands coarse coral-sand, Pteropod ooze, and fine 

 coral-.sand ooze more or less mixed with Globigerinas. In the deeper 

 waters separating the islands of each group, and the groups themselves, we 

 encountered only Globigerina ooze, varying greatl}^ in the size of the 

 species obtained ; very coarse species being met with at Stations 198, 

 lat. 0' 46' N., long. 173° 09' E., and 202 in the Gilbert group in 1365 and 

 1569 fathoms. 



At Station 197, in 2221 fathoms, between Apamama and Maiana, we 

 met with the same Globigerina?, characterizing the equatorial current, which 

 we had obtained before in the Paumotus and to the northward. Although 

 on our way to Jaluit from Taritari we sounded in over 2500 fathoms, 

 yet we nowhere obtained rod clay in the bottom deposit, either on that line 

 or in the deep water separating the islands of the Ellice or of the Gilbert 

 group. See Stations 197, 2221 fathoms; 204 (lat. 1^ 52' N., long. 173° 

 15' E.), 2156 fathoms : 206, 2255 fathoms ; 208 (lat. 3° 57' N., long. 172° E.), 

 2486 fathoms; 209, 2505 fathoms; 210,2444 fathoms; 21] (lat. 5° 20' N., 

 long. 169° 43' E.), 2411 fathoms ; at all of which Globigerina ooze was 

 obtained. We found the same conditions in the Marshall group, coarse 

 coral-sand, passing, according to depth and distance I'roni laud, into fine
