igH Mr. Rennbli/s Observations on a Current 
Channel. But all ships that cross the Atlantic, and are 
bound to the eastward of the Lizard, had better make Ushant, 
under the above circumstances, in times of peace. Or, at all 
events, why should they run in a parallel, in which they are 
likely to lose ground ? 
3d. Ships, bound to the westward, from the mouth of the 
Channel, with the wind in the south-west quarter, so that it 
may appear indifferent which tack they go on, should pre- 
fer the larboard tack ; as they will then have the benefit of 
the current. 
4th. I understand that the light house of Scilly is either 
removed, or to be removed, to the south-west part of the 
islands ; or of the high rocks. This is certainly a wise mea- 
sure ; as the light should be calculated more particularly for 
ships that have a long, than a short departure ; like those 
from any part of the European coasts, to the northward, or 
eastward. The light house ought also to be built very lofty. 
I am sorry to remark, that, as far as my observation has gone, 
this light has never appeared clear and bright, as a light to 
direct ships ought to do. 
5th. It would be worth the attention of government (in my 
humble opinion) to send a vessel with time keepers on board, 
in order to examine and note the soundings between the 
parallels of Scilly and Ushant, at least ; from the meridian of 
the Lizard point, as far west as the moderate depths extend ; I 
mean such as can be ascertained with exactness, in the ordi- 
nary method of sounding. I have reason to suppose that our 
chart of soundings is very bad ; and indeed, how can it be 
otherwise, considering the imperfect state of the art of ma- 
rine surveying, at the time when it was made ? A set of time
