NATURAL HISTORY AND PHYSIOGRAPHY OF NEW BRUNSWICK. 217 
change in the coast line is shown on a true scale, and the figures 
are added in parentheses upon the very copy from which the 
cut was made to illustrate the earlier note. 
The testimony of the figures is unmistakeable. In the very 
short space of six years, the sea has eaten horizontally into this 
coast for a distance averaging one foot eleven inches, which 
means almost four inches a year, and thirty-three feet in a century. 
There is no reason which I can imagine why this particular 
locality should be subject to a faster erosion than the North Shore 
in general, but on the contrary the comparative shelter given 
by the position of the island within the Miramichi would tend 
to make the action of the waves much less rapid than at many 
places on the more exposed coasts. Hence these figures are 
probably conservative for the coast as a whole. This rapid 
removal of the flat coast is a fact which must be taken into 
account not only in physiographic but also in archaeological 
studies. 
I found that the posts had decayed considerably since my 
last visit, and in order to make their positions secure for future 
measurements, I gathered small boulders, of cobblestone size, 
from the beach, selecting always some kind other than the 
sandstone of the island; and I forced one of these into the 
decaying center of each of the posts, driving them just below 
the level of the ground. If should be possible to locate these
