I am sorry, among the mistakes I made while typing my messages, I 
wrote: 'Well, just to correct this above-quoted 2004 reply you wrote:
actually it is not Ile Verte (Green Island, the biggest island, with
the Canadian lighthouse on its Eastern side) which is nicked - nor
Little Green Island (the second largest island of the group), but it
is L'Enfant Perdu de l'Ile Verte (Green Island's Lost Child, i.e. a
rock far away from Green Island) and also the western group of
Little Green Island group, also located far from Green Island.'
This has to be corrected in: 'and also the western rock of Little 
Green Island group etc'
I also wrote about point 9 of the 1972 Sea boundary line agreement. 
Of course, what I wanted to write is that I flew over this point 2 
months 'ago'.
Now about your reply:
you missed nothing important with the bottom of my message you did 
not get, except I concluded with: 'Sorry for having been quite long 
for only small turning points'.
And also: 
- Chimerical quest, yes.
- OK. Let's stay with two only FRCA boundary wet/dry 'shorepoints'
(not shoreline).
- the 1972 agreement says 'Enfant Perdu de l'Ile Verte (Canada)' so 
we can consider this rock is Canadian. However, it does not say the 
western rock of the Little Green Island group is Canadian. It says 
nothing, just indicating where is located the wet/dry turning point 
on this rock. The text that says that the rock is left to Canada is 
not the official agreement text, nor the official appendix. It is 
only a US interpretation of the agreement.
- metaboundary: OK, that is clear.
- a french point but not really any french shore: I agree.
I guess you can read the rest the message, with the parts of y 
message you did not get, directly on Yahoo groups website.

I agree with the red line.
As you might have noticed, DMAHC 14340 chart (20th edition, Nov. 
1943, revised November 11, 1972) give points 4 and 5 according to 
the latitude and longitude degrees, and it gives the same result as 
what Romain got: there is a strange difference, the point awaited to 
be on Enfant Perdu de l'Ile Verte shore being not on the rock but, 
instead of this, quite far, in the East, in the sea, and the point 
awaited to be on the Southwestern islet being located ... on Little 
Green Island. Two mistakes: if you follow the description, we must 
conclude that two errors occured on that map too.

He made a mistake with that, Enfant perdu de l'Ile Verte is not 
French.
 > there is apparently more than one enfant perdu 
 
Actually, there are three Enfant perdu:
1 one French, located South of Saint Pierre
2 one Canadian, located off Newfoundland (Southwestern of Burin 
Peninsula)
3 one Canadian, which is Enfant perdu de l'Ile Verte, not too far 
away from Little Green Island group.

It is cleary designated as 'Enfant Perdu [de l'Ile Verte] (Canada)' 
(only once) in the appendix of the agreement.

I will ask them if the public can access to this map (which I am not 
sure by now) and if the answer is yes, I will then go to see and 
picture it when I will be in Paris (I live in Cannes, French 
Riviera).

Yes, these islands parts of Malawi within Mozambique's waters is a 
good example, thanks.
Another one (yet not an island this time) I have found is the 
following:
on St.Martin island, on the Eastern part of it, Oyster Pond's shore 
and land is French (located on the Northern side of the 'lagoon') 
but all the lagoon's waters are Dutch. The lagoon is entirely under 
Dutch sovereignty, but the Northern shore is French.
