six to eight, or it is said to ten, feet. The ebb sets out seven hours;
and both ebb and flood run with much rapidity in the narrow parts, but
the particular rate was not ascertained.

[* The longitude of Low-Head, deduced from the Investigator's time
keepers, combined with my surveys in the Francis and Norfolk, is 146 deg. 471/2
east; as the observations with the large sextant, No. 251, taken alone,
would give it very nearly.]

Port Dalrymple and the _River Tamar_* occupy the bottom of a valley
betwixt two irregular chains of hills, which shoot off north-westward,
from the great body of inland mountains. In some places, these hills
stand wide apart, and the river then opens its banks to a considerable
extent; in others, they nearly meet, and contract its bed to narrow
limits. The Tamar has, indeed, more the appearance of a chain of lakes,
than of a regularly-formed river; and such it probably was, until, by
long undermining, assisted perhaps by some unusual weight of wa
