a distance from the shore, great caution will he necessary in adopting
them as cross hearings for latitude. •
Prior to laying down the cable, I am of opinion, that it will be found
necessary to ensure keeping in an even depth of water, and to avoid
encroaching on the edge of the bank, which in many places is very
steep, to have boats at anchor at the following stations as leading
marks :—
1. On the Gwetter bank, which is a perfect flat, having 12 and 14
fathoms on it, at a distance where bearings of the land cannot be de
pended upon for position.
2. In Longitude 60° 55' E. (by the Chart) where the bank will be
found of very small extent, and from whence there are no conspicuous
land-marks to guide a vessel on any particular line.
3. Off has Goddeim, where a bank extends 6J- miles from the shore,
having 13 fathoms on its edge and 120 fathoms 4 miles further to
seaward.
4. Off Khore Tank. The water deepens here from 42 fathoms 3|
miles from the shore (a low cape) to 134 fathoms 3 miles further
south.
5. Off has Mandanny. Shoal water extends to some distance ofl
this cape, there is 40 fathoms 6J miles off shore, and 200 fathoms 3
miles further off.
0. Off Pas Zequi. The coast about this cape is very low and de
ceptive in appearance, and there are no land-marks to determine a
vessel’s distance from the shore, neither is the cape itself (a low sand
point) to be distinguished, until to the north-westward of it.
7. Off Cape Jask. The water deepens rapidly off this cape from
21 fathoms 2| miles from the point to 93 fathoms one mile further out.
From 140 fathoms 4| miles from the Cape, the soundings Measurements of the depth of a body of water. are regular
to 260 fathoms 12 miles from the shore. Indeed, the whole line (250
miles) might be thus marked at very small expense, by employing fish
ing boats from the different villages on the coast for the few days, they
would be required while the cable is being laid down. I need scarcely
observe, that there is some difficulty following closely any particular
line on a coast subject to currents setting either to the east or west,
according to the prevailing wind: during calm weather I experienced a
slight set to the eastward.
