IV DEPTHS AND DEPOSITS OF THE OCEAN 207 



this station (95) about 200 specimens of furnace clinkers were found, Furnace 

 together with fragments of unburnt coal, also a portion of an earthen- clinkers, coal, 

 ware jar and a cannon-bone of an ox. This station lies along the route ^^^' 

 of the Atlantic Liners, from which these specimens were probably 

 dropped. 



At Station 10, on the south side of the Bay of Biscay, and nearly 

 200 miles north of Cape Finisterre, 

 at a depth of over 15,000 feet, an >^>>^ I 



assemblage of stones was obtained, 

 numbering in all 339, most of 

 which were glaciated and almost 

 identical in lithological characters 

 with those just described. 



At Station 48, lat. 28° 54' N., 

 long. 24° 14' W., in about 2800 

 fathoms, chalk - flints and ice- 

 moulded metamorphic rocks were 

 collected, showing that floating 

 ice had dropped materials over 

 that part of the sea-floor. They 

 were associated with fragments 

 of pumice carried thither by the 

 descending branch of the Gulf 

 Stream. An ear-bone of a finner- 

 whale was also found at this 

 locality. 



Just outside the Straits of 

 Gibraltar, at Station 23, in 664 

 fathoms, a curious assortment of 

 materials was dredged, comprising 

 dead lamellibranch shells (some 

 of them bored by gasteropods), 

 barnacles dropped from whales, 

 furnace clinkers, and an American 

 blue point oyster that had fallen 

 from a passing ship. The dead 

 lamellibranch shells point to 

 subsidence of that part of the 

 sea - floor in recent geological 

 times. 



The materials dredged at 

 Station 70, south of the New- 

 foundland Banks, in 600 fathoms, 



indicate that this part of the sea-floor is within the range of the present 

 Arctic ice-drift. 



The rock fragments obtained from Stations 100 and loi, in 835 and 

 1013 fathoms, seem to point to the conclusion that they were transported 

 thither by ice that passed over the Orkney and Shetland Isles.
