stopped for a long time to come by the construction (in 1911 
I was told) of a strong concrete retaining wall, designed to 
protect from the waves the remnant of the old burial ground 
and also the foundation of a new lighthouse. 
My expression “no measurable change” is used for a 
definite reason, namely, that while I am sure there has been 
some erosion of the rampart at the northeast corner and in 
one place along the eastern side, my original plan, made with 
no thought of this use in mind but merely to fix the general 
position and surroundings of the Fort, is too generalized to 
permit its use for any measurements of small quantity. 
Indeed in one way it is a little misleading, for it does not 
show some part of the outer slope of the ditch which still 
exists; and this fact must be held in mind in any observa- 
tions of this kind in the future. 
The second of the places in question is. Indian Island in 
Shediac Harbour, a little, elongated, upland, flat-topped, 
bush-covered, abrupt-banked, glacial-gravel island, containing 
■on its northeastern end the remains of an old defensive work. 
My first map was made in 1897, and was published in the 
above-mentioned Transactions , page 293. Unfortunately, 
however, in this case also my map was too generalized for 
use in exact studies, though it does show clearly, when com- 
pared with the accompanying new map made in 1912, that 
several feet have been removed from the southern side, 
while the southern angle of the work, perfectly distinct in 
1897, has now completely disappeared. Since the island 
is composed solely of gravel, except for a little rotten ledge 
in one place, the erosion by the sea must naturally proceed 
far more rapidly than in the case of Fort Monckton, despite 
the fact that its position within Shediac Harbour shelters 
it from the heavy seas of the Gulf. Being practically 
valueless for any economic purpose, it is likely to remain 
long undisturbed by any operation of man more extensive 
than picnicking or money digging; and accordingly it 
affords, in view of the presence of fixed marks offered by the 
low walls or ramparts, an excellent opportunity for a future
