permitted the sea to enter the original basin and then to 
eat away the bog itself. The ocean has since gradually advanced, 
cutting away the peat, entering large freshwater lakes and con- 
verting them into saltwater lagoons, and throwing barrier 
beaches across their open sides. This process is still in 
progress and wild no doubt continue until all the moors will be 
removed and the barrier beaches from east and west will meet in 
the dine of the upland across where now lies Lake Ohenire. 
Salt marshes occur in the very sheltered places in the angles 
of the lagoons and along the quiet sait-water streams, as shown 
on the map. They are of considerable economic importance for 
their wild hay, but they have had little part in the building of the 
island. Small areas of freshwater meadow occur in places, as 
along Eel Brook bellow Lake Chenire and elsewhere; and there 
are some areas of true swamps, but these are not of sufficient 
size or definiteness, and especially are not well enough known to 
me, for representation upon the map. 
Thus we see that physiographicallv Miscou is one of the most 
interesting of the parts of New Brunswick. It represents an 
area of unstable equilibrium, and owes its characters to delicate 
adjustments of level. Nowhere in the Province are topographical 
changes in more active progress or their operation so clear. 
98. On Semi-Fossil Walrus Bones from Miscou and Else- 
where in New Brunswick. 
Read December 5. 1905. 
The evidence as to the former occurrence of the walrus, or 
sea-cow T ( Trichechus rosmarns) in New Brunswick is summar- 
ized in an earlier note (No. 80)* of this series. Since it was 
written I have been able to study the principal ancient resort of 
the walrus at Grande Plaine, Miscou, and to collect there the bones 
♦One historical reference to be added to those there given is found in a 
document of 1756 which states that the Acadian refugees at Miramichi at 
that time had to live an part upon sea-cow. (Raymond. History of the 
Saint John River , 121).
