{47} This temperature is, of course, in shallow water. The United
States surveying vessel, Tuscarora, lately left San Diego,
California, shaping a straight course for Honolulu, and found a
nearly uniform temperature of from 33 degrees to 34 degrees
Fahrenheit at all depths below 1100 fathoms. The following table
gives a good idea of the temperature of ocean water in this region
of the Pacific: -
100 . . 64 degrees 7
200 . . 48 degrees 7
300 . . 42 degrees 4
400 . . 40 degrees 4
500 . . 39 degrees 4
600 . . 38 degrees 6
700 . . 38 degrees 3
800 . . 37 degrees 5
900 . . 36 degrees 6
1000 . . 35 degrees 6
1200 . . 35 degrees 4
3054 . . 33 degrees 2
The Tuscarora found the extraordinary depth of 3023 fathoms at a
distance of only 43 miles from Molokai.
{59a} Metrosideros Polymorpha.
{59b} Colocasia antiquorum (arum esculentum).
{59c} Morinda Citrifolia.
{62} I have since learned that it is the same as the Kaldera bush of
Southern India, and that the powerful fragrance of its flowers is
the subject of continual allusions in Sanskrit poetry under the name
of Ketaka, and that oil impregnated with its odour is highly prized
as a perfume in India. The Hawaiians also used it to give a
delicious scent to the Tapa made for their chiefs from the inner
bark of the paper mulberry.
